Abstract
Nanotechnology is currently one of the fastest growing scientific fields. The products of this science have become part of our everyday lives. However, to date, regulatory agencies have not yet established a single definition for nanomaterials and nanotechnology. Therefore, each country has its own definitions and legislation to control products containing nanomaterials. Being relatively new materials, there are no long-term studies showing their impact on human health and the environment. Consequently, countries control the amount of nanomaterials present in cosmetics, allowing the end consumer to choose which cosmetic to use, by choosing products with or without nanomaterials. Therefore, the primary objective of this study was to identify the most used nanomaterials in cosmetics and verify whether these formulations are in accordance with the laws in force in the United States, the European Union and Brazil, thereby determining if the cosmetics on the market are in line with the existing laws in these three economic powers. This study is unique and will contribute to furthering the discussion on existing laws pertinent to the use of nanotechnology in cosmetics.

INTRODUCTION
What's Nanotechnology?
Nanotechnology is the science of manipulating atoms at the nanometer scale (1 nm = 10-9 m), creating a new organizational structure presenting different behaviors and properties of materials currently known.11 Cadioli, L.; Salla, L. D.; R. C. Exatas e Tecnol. 2006, 1, 98.
From a molecular standpoint, many nanomaterials are equal or very similar to bulk materials with higher dimensions and dependent size.22 Daniel, M. C.; Astruc, D.; Chem. Rev. 2004, 104. Thus, the fluorescence properties, melting point, chemical reactivity, electrical conductivity, magnetic permeability, change according to the particle size used in the formulation of products.22 Daniel, M. C.; Astruc, D.; Chem. Rev. 2004, 104. Moreover, reduction in particle size results in increased area/volume ratio. Thus, the nanoparticles have area surface/mass unit ratio much greater than the larger particles of the same material, which increases their reactivity,33 Oberdorster, E.; Environ. Health Perspect. 2004, 112. being more used in cosmetic and pharmaceutical formulations, although their cytotoxicity is controversial.
Nanotechnology
Since last decade, the nanotechnology has been acquired prominence in several
Science fields. This science is increasingly inserted in our daily life being
used as raw in cosmetics and pharmaceutical materials, in the manufacturing of
packaging.44 Kimbrel, G. A.; Global Regulatory Issues for the Cosmetics
Industry
2007, 1, 117. As vectors for gene
manipulation, diagnosis and anticancer treatment.55 Knopp, D. Tang, D.; Niessner R.; Anal. Chim. Acta
2009, 647. As adjuvants in the formulations of vaccines and antimicrobials,
and in the development of tools and analytical instruments.55 Knopp, D. Tang, D.; Niessner R.; Anal. Chim. Acta
2009, 647. Moreover, because it is a multidisciplinary technology,
it is applied and covers several areas such as physics, chemistry, biology and
medicine.66 http://www.nano.gov/nanotech-101/what/definition, acessada em Julho

However the scope of
nanotechnology is vast, the great highlights are in the development of
nanoelectronics.11 Cadioli, L.; Salla, L. D.; R. C. Exatas e Tecnol.

The National Science Foundation estimates that nanotechnology
reaches an impact on the overall economy of about $ 1 trillion by 2015,
requiring approximately two million workers.88 Ramos, B. G. Z.; Pasa, T. B. C.; Rev. Bras. Farm.

2012, 13, 45. The highest
level of development in nanotechnology is found in the United States, Union
Europe and Japan, which invested about a billion dollars a year, and represent
almost half of the investments in the world. However, countries such as Russia,
China, India and Brazil have made significant investments in the sector the last
years. The Brazilian government invested R$ 140 million between 2001 and 2006 in
research networks and projects in the areas of nanotechnology.88 Ramos, B. G. Z.; Pasa, T. B. C.; Rev. Bras. Farm.

Nanotechnology and the cosmetics market
The nanocosmetic aims products intended for application to the skin of the face and body, with anti-aging action and photo protection, capable of penetrating into the deep layers of the skin, potentiating the effects of the active.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45.,1111 Neves, K.; Cosmet. Toiletries 2008, 20, 22.
Fronza and collaborators in 2007 defined nanocosmetic as "a cosmetic formulation that carries actives or other nanostructured ingredients, which has superior properties regarding its performance if compared with conventional products".99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45.,1212 Fronza, T.; Nanocosméticos: em direção ao estabelecimento de marcos regulatórios, 2007.
In the cosmetic industry, the nanoparticles are present in shampoos, conditioners, toothpastes, anti-wrinkle creams, anti-cellulite creams, whitening skin, moisturizing, face powders, aftershave lotions, deodorants, soaps, sunscreens, make up in general, perfumes and nail polishes.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45.,1111 Neves, K.; Cosmet. Toiletries 2008, 20, 22.,1212 Fronza, T.; Nanocosméticos: em direção ao estabelecimento de marcos regulatórios, 2007. The nanoemulsions, in turn, constitute a class of emulsions with uniform droplets of small size in the range between 20 and 500 nm, which become increasingly popular as vehicles for the controlled release and optimized dispersion of active ingredients.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45.,1313 Capek, I.; Adv. Colloid Interface Sci. 2004, 107, 125.
Although widely used in cosmetics, it is necessary to choose carefully the carrier of the active substance. Therefore, products, which intended to remain on the skin without absorption,
such as sunscreens, are formulated to meet this end. When a highest penetration is expected, another active should be used. The first products that promised to combat wrinkles were limited to exfoliate the most superficial epidermis layer - the stratum corneous. In the 70s, there were creams whose formulations contained substances that could penetrate the skin, but only the stratum corneous. In the 80s, alpha-hydroxyl acids have emerged, with penetration capability slightly higher. In 1990, appeared the liposomes, tiny particles composed of fat and water that reached deeper in the skin, but not on the basal layer.77 Kim, J.; Park, S.; Lee, J. E.; Jin, S. M.; Lee, J. H.; Lee, I. S.; Yang, I.; Kim, J. S.; Kim, S. K.; Cho, M. H.; Hyeon, T.; Angew. Chem. Int. Ed. Engl. 2006, 45, 7754.
The advantages of using nanocosmetics come from protecting ingredients from chemical or enzymatic degradation; control their release, especially in the case of irritant at high doses, and the prolongation of residence of cosmetic actives or drugs in the stratum corneous.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45.,1111 Neves, K.; Cosmet. Toiletries 2008, 20, 22.,1212 Fronza, T.; Nanocosméticos: em direção ao estabelecimento de marcos regulatórios, 2007.
The first company to introduce a nanotechnology-based cosmetic was Lancôme, the luxury division of L'Oréal in 1995, with the launch of a cream face composed of nanocapsules of pure Vitamin E, to combat skin aging.77 Kim, J.; Park, S.; Lee, J. E.; Jin, S. M.; Lee, J. H.; Lee, I. S.; Yang, I.; Kim, J. S.; Kim, S. K.; Cho, M. H.; Hyeon, T.; Angew. Chem. Int. Ed. Engl. 2006, 45, 7754. From this release, other international companies started to invest in researching to develop nanocosmetics.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45.,1111 Neves, K.; Cosmet. Toiletries 2008, 20, 22. Meanwhile, companies such as Christian Dior, Anna Pegova, Procter & Gamble, Revlon, Dermazone Solution, Chanel, Skinceuticals, Estee Lauder, Shiseido, Garnier, Johnsons & Johnsons developed products in this line.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45.
In Brazil, the first company to develop and market a nanocosmetic was O Boticário. It produced an anti-aging cream for the area of the eyes, forehead and around the mouth, called Nanoserum. The nanostructure composition takes active as vitamin A, C and K and a product for whitening.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45. The technology, developed in partnership with the French laboratory Comucel had investment of R$ 14 million and is part of the Active line, which began to be sold in 2005.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45. In 2007, launched the VitActive Nanopeeling Renovator Microdermabrasion, anti-aging cosmetic with applied nanotechnology. Other items include Lift serum Anti-aging and Anti-aging 65+ Advanced System. Natura, in turn, launched in 2007 a product to body hydration, called "Brumas de Leite", with particles of approximately 150 nanometers. In the same year it also put on the market the "Refreshing Body Spray" to the male public.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45.,1111 Neves, K.; Cosmet. Toiletries 2008, 20, 22.
Therefore, the cosmetic industry uses nanotechnology due to several advantages of its implementation, especially regarding to higher penetration capacity of actives in skin layers. However, only in a near future, with a larger and more effective development of this technology, it will be more clearly observed its real benefits and the safety of products offered with this appeal. The possible risks in applying nanoparticles include possible toxicity and absence of biocompatibility of the materials used.99 Baril, M. B.; Franco, G. F.; Viana, R. S.; Zanin, S. M. W.; Visão Acadêmica 2012, 13, 45.,1414 Alvarez-Román, R.; Naik, A.; Kalia, Y. N.; Guy, R. H.; Fessi, H.; Pharm Res 2004, 21, 1818.
Thus, regulations become necessary to ensure that this technology is within the current legislations.
Nanotechnology and legislation
Until now, grant and regulatory agencies have not yet established the exact definition of Nanotechnology. So, each country has its own definition and legislation.
International ASTM (American Society for Testing and Materials)
recognized worldwide for developing international standards published in 2006
the first formalized definition of Nanotechnology. Thus, any technology that
measures, manipulates or incorporates materials and / or resources from 1 to 100
nm is known as Nanotechnology.1515 http://www.astm.org/Standards/nanotechnology-standards.html,
acessada em Julho 2014.
http://www.astm.org/Standards/nanotechno...
This
concept is very similar to the declared by the National Nanotechnology
Initiative (NNI),1616 http://www.nano.gov/sites/default/files/pub_resource/nanotechnology_bigthingsfromatinyworld-print.pdf,
acessada em Julho 2014.
http://www.nano.gov/sites/default/files/...
this
center is a government initiative of the United States of America (USA), which
encompasses 20 departments and federal regulatory agencies of research and
development (R&D) involved with the use, creation and manipulation of
nanotechnology. According to NNI, nanotechnology is the development,
understanding and control of materials at the nanoscale ranging from 1 to 100
nm.1616 http://www.nano.gov/sites/default/files/pub_resource/nanotechnology_bigthingsfromatinyworld-print.pdf,

http://www.nano.gov/sites/default/files/...
Moreover, it also enacts its
scientific application in several fields of study such as chemistry, biology,
physics, medicine and engineering. Furthermore, the 2015 Federal Budget provides
more than $1.5 billion for the National Nanotechnology Initiative (NNI), a
continued investment in support of the President's priorities and innovation
strategy.1717 http://www.nano.gov/about-nni/what, acessada em Julho

http://www.nano.gov/about-nni/what...
In 2011, the European Commission published a definition of nanomaterial. They
defined as a natural material, made accidentally or purposely containing 50% or
more of free particles, aggregated or agglomerated with size between 1 and
100nm.1818 http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2011:275:0038:0040:EN:PDF,

According to the Guidance for Industry, published in 2014, the U.S. Food
and Drug Administration (FDA) has not established regulatory
definitions of "nanotechnology," "nanomaterial," "nanoscale," or other related
terms. In June 2014, FDA issued a guidance for industry titled "Considering
Whether an FDA-Regulated Product Involves the Application of
Nanotechnology".1919 http://www.fda.gov/RegulatoryInformation/Guidances/ucm257698.htm,

http://www.fda.gov/downloads/cosmetics/g...
As described in that guidance, at this
time, when considering whether an FDA-regulated product involves the application
of nanotechnology, FDA will ask: (1) whether a material or end product is
engineered to have at least one external dimension, or an internal or surface
structure, in the nanoscale range (approximately 1 nm to 100 nm); and (2)
whether a material or end product is engineered to exhibit properties or
phenomena, including physical or chemical properties or biological effects, that
are attributable to its dimension(s), even if these dimensions fall outside the
nanoscale range, up to one micrometer (1,000 nm).1919 http://www.fda.gov/RegulatoryInformation/Guidances/ucm257698.htm,

http://www.fda.gov/downloads/cosmetics/g...
We will apply these considerations broadly to all FDA-regulated products,
including cosmetic products. The National Institute for Public Health and the
Environment published the Nanomaterial Report of products for human consumption
in the European market in 2010.2121 http://www.nanogenotox.eu/files/PDF/rivm%20rapport%20nanomaterials%20in%20consumer%20products%2023-02-2011.pdf,

http://www.nanogenotox.eu/files/PDF/rivm...
In the
past three years, the number of consumer products with a claim to contain
nanomaterial on the European market shows a six-fold increase from 143 products
in 2007 to 858 products in 2010. Product categories with the largest growth are
the 'Personal care products and cosmetics' like sunscreens and various 'Coating
products' such as anti-rain products for shoes and textiles.2121 http://www.nanogenotox.eu/files/PDF/rivm%20rapport%20nanomaterials%20in%20consumer%20products%2023-02-2011.pdf,

Nowadays, there is great difficulty in identifying products containing nanomaterials, because depending on the manufacturer, this may choose, or not to declare the presence of nanomaterials. This occurs because there are no scientific evidences of risks that these nanomaterials may offer to health and environment in short and long term. As the advertising and publicity on these nanocosmetics is eager and intense, many manufacturers declare the presence of nanoparticles for commercial purposes, however, not necessarily they are found in the products.
Actually, there is growing concern of national and international regulatory agencies to promote the declaration of nanomaterials in cosmetics by manufacturers and suppliers. The main national and international regulatory agencies began requiring that both manufacturers and suppliers describe, characterize and detail if their product has any nanomaterial, the chemical identity of its nanomaterial, its concentration and form. In this way, every year the laws become more stringent and demanding not only in Brazil, but around the world.
Regulatory laws of nanomaterials
Prioritizing the principal markets and influencers of today, there were identified what are the main regulatory agencies of these countries and what are the laws for exportation and marketing of finished products containing nanomaterials.
European Union
The main legal instruments of the European Union (EU) are the Directives and Regulations. Regulations are applied to all Member States (28 countries). In 2009, the New European Regulation for Cosmetics was released.2222 European Union. Regulation (EC) No 1223/2009 of the European Parliament and the Council of 30 November 2009 on cosmetic products.; 2009, 59-209, European Union, Official Journal of the European Union, http://ec.europa.eu/consumers/consumers_safety/cosmetics/legislation/index_en.htm.
Regulation 1223/2009
Nanomaterials are defined as "insoluble or biopersistant and intentionally manufactured material with one or more external dimensions, or an internal structure, on the scale from 1 to 100 nm". However, this definition is not definitive, and to maintain a high level of consumer protection, free movement of goods and a legal support to manufacturers, it is necessary a uniform and international definition of "nanomaterials".2222 European Union. Regulation (EC) No 1223/2009 of the European Parliament and the Council of 30 November 2009 on cosmetic products.; 2009, 59-209, European Union, Official Journal of the European Union, http://ec.europa.eu/consumers/consumers_safety/cosmetics/legislation/index_en.htm.
Regulation 1223/2009 requires that the ingredients present, as nanomaterials in the product shall be indicated in the ingredient list with the word "nano" in brackets.
REACH Regulation (Registration, Evaluation, Authorization and Restriction of
Chemicals) follows the norms of the Regulation 1223/2009 and it is applied to
every substance, which includes the nanomaterial. According to REACH,
manufacturers, importers and consumers should ensure that manufacture, market or
use substances that do not affect the environment and human health.2323 http://ec.europa.eu/enterprise/sectors/chemicals/reach/index_en.htm,
acessada em Setembro 2013.
http://ec.europa.eu/enterprise/sectors/c...
So, manufacturers and importers must submit a registration dossier of substances
that go to or are manufactured in the EU, above 1 ton/year. When quantities
reach or exceed 10, 100 and 1000 tones/year, a safety report (Chemical Safety
Report) and a Safety Assessment must be included in the registry.2323 http://ec.europa.eu/enterprise/sectors/chemicals/reach/index_en.htm,
acessada em Setembro 2013.
http://ec.europa.eu/enterprise/sectors/c...
Minimum information required for
registration, if not available must be justified:
1. Name or other identifier of the substance
1.1. IUPAC name or other international nomenclature (INCI name)
1.2. Other names (usual name, trade name, abbreviation)
1.3. EINECS/ELINCS number
Article 16 of Regulation 1223/2009 stipulates that all cosmetic products
containing nanomaterials must be notified electronically within six months prior
to commercialization in the EU.2222 European Union. Regulation (EC) No 1223/2009 of the European

In the U.S., the National Science and Technology Council coordinates the policies
on nanotechnology through the Nanoscale Science, Engineering, and Technology
Subcommittee (NSET).2525 http://www.nano.gov/nanotech-101/what/manufacturing, acessada em

The Subcommittee is responsible for
coordinating, planning, implementing and reviewing the National Nanotechnology
Initiative (NNI).1717 http://www.nano.gov/about-nni/what, acessada em Julho
2014.
http://www.nano.gov/about-nni/what...
The NNI is not a regulatory agency, but it aims to provide recommendations for evaluation and risk administration of nanomaterials, increasing the conscious development of nanotechnology.2727 Gwinn, M. R.;Sokull-Kiattegn, B.; Regulation and Legislation, in Adverse Effects of Engineered Nanomaterials (Exposure, Toxicology, and Impact on Human Health), B. Fadeel, A. Pietroiusti, and A. Shvedova, Editors. 2012, Elsevier. p. 97-117.
The TSCA (Toxic Substances Control Act) aims to allow the U.S. EPA
(United States Environmental Agency Protection) to control new chemical products
before being marketed and existing products when they present excessive health
and environmental risk, and to control their use and distribution.2828 http://www.epa.gov/agriculture/lsca.html#Summary of Toxics
Substances Control Act (TSCA), acessada em Setembro 2013.
http://www.epa.gov/agriculture/lsca.html...
For this approach, the TSCA has four fronts:
-
Premanufacture Notifications - requires manufacturers of new chemicals to provide specific information, so that the Agency can do a review before production and/or marketing.
-
Significant new use rule (SNUR) - to ensure that new nanomaterials have appropriate regulatory review and to identify the existing uses of these nanomaterials. It requires that the manufacturer or importer submit a Significant New Use Notice (SNUN) to EPA until 90 days before marketing. The Notification should contain basic information about nanomaterials: chemical identity, characteristic of the material, physical/chemical properties, commercial uses, production volume, exposure and toxicological data.
-
Information Gathering Rule - Requires manufacturers of nanomaterials to send additional information such as production volume, manufacturing and processing methods, exposure and release information, and available health and safety data.
-
Test Rule - Requires testing for certain nanomaterials that are already on the market. The test results would assist EPA in understanding the potential effects to health and environment. Besides, they can establish a correlation among the physic-chemical properties and the effects of nanomaterials.
The FDCA (Food, Drugs and Cosmetics Act) is used by FDA to control
and understand, the uses and impacts of nanomaterials in foods (additives and
contaminants), drugs and cosmetics. The FDA may request information about the
identity and properties of the materials, regardless of particle size. Usually,
premarketing safety data are not required for cosmetics.2020 http://www.fda.gov/downloads/cosmetics/guidancecomplianceregulatoryinformation/guidancedocuments/ucm300932.pdf,

Currently, there are no specific regulations for nanomaterials related to the
safety of food and drugs. Medical products that contain nanomaterials undergo
traditional regulatory processes and are required clinical and toxicological
tests to determine their safety and effectiveness.2727 Gwinn, M. R.;Sokull-Kiattegn, B.; Regulation and

At the present time, in Brazil, there are no laws or regulations governing the
nanomaterials and nanotechnologies. On 31/10/2012, ANVISA (National Agency for
Sanitary Vigilance) promoted a thematic discussion on nanotechnology and health
surveillance, when they discussed the growth of nanotechnology and the need to
enhance the Agency's knowledge in this area.3030 http://portal.anvisa.gov.br/wps/content/anvisa+portal/anvisa/sala+de+imprensa/menu+-+noticias+anos/2012+noticias/nanotecnologia+e++tema+de+debate+na+anvisa,

Comitê Interno de Nanotecnologia).3131 http://portal.anvisa.gov.br/wps/content/anvisa+portal/anvisa/sala+de+imprensa/menu+-+noticias+anos/2013+noticias/agencia+avalia+nanotecnologias+para+a+saude,

It aims to: verify the current understanding of the
Agency about nanotechnology; account products that use and have knowledge in
nanotechnology; prepare a document with the actions and regulatory policies on
nanotechnology present in other countries; and suggest alternatives guidelines
and regulatory policies to the Agency.
In February 2014, CIN published the "Diagnóstico Institucional de Nanotecnologia" (Institutional Diagnosis of Nanotechnology). According to it, in Brazil there are 608 industries that uses nanotech, 150 industries develop nanotech and in the major areas (chemical and petrochemical industry and health).
Were identified 637 products that make reference to nanotechnology, which: 599 cosmetics, 20 sanitizing, 10 drugs, 7 health products and 1 food.
By the end of the document, some considerations are made, such as:
-
The necessity to regulate nanotechnology, due to its high degree of uncertainty about its safety, and also, the absence of regulation creates legal uncertainty which is detrimental to the development, production and marketing.
-
There are several nanoproducts on the market without specific technical analysis.
-
It is necessary a qualification in this field of knowledge.
-
It is necessary to keep up with the evolution of the international regulatory scenario, which is dynamic.
-
There are still conceptual, technical, scientific and structural limitations to have a scientifically referenced regulation.
CIN also made some suggestions:
-
Elaboration of a norm that obliges to declare the nature of the nanotechnology used in products and process registered/notified in ANVISA.
-
Elaboration of norms and guidelines for the safety evaluation, monitoring and control of the products and process.
-
Stimulate the financing of regulatory research to overcome significant gaps for the establishment of more specific regulations for nanotech.
-
Create a database of nanoparticles/nanomaterials related to human health and environment safety.
CONCLUSION
Nowadays, nanotechnology is one of science's important topics; it is a promising area for the development of drugs, health products, digital devices and others. However, its effects and impacts in health and environment are still not clear.
In this way, its evaluation and regulation are very important. It was seen that there are several different definitions and positioning regarding nanotechnology and nanomaterials, for each country, each regulatory agency.
The "lack" of a single and international definition may harm consumers (who do not know the actual properties of the products they are buying/using) and also manufacturers/suppliers (who find themselves without legal guidance on how to use and sell this technology and its products).
The next challenge would be a deeper alignment among the main regulatory entities and research centers that have better understanding about this subject, to lead to a single definition of those terms. In addition, they can create a database that would include: the products containing this technology, the tests already carried out, and other information, aiming the products efficacy and mainly the safety of human health and environment.
