Trace impurities/ contaminants
• Presence of small quantities of a non-intended prohibited substance, that is technically unavoidable in good manufacturing practice, is allowed, provided that it does not cause harm to human health during the product use.
• Annex I requires the following information concerning the impurities and traces in the cosmetic product safety report:
• The purity of the substance and mixtures.
• In the case of traces of prohibited substances, evidence for their technical unavoidability.
• The relevant characteristics of packaging material, in particular purity and stability.
• There are currently not regulatory limits for most non-intended traces
• Safety is the responsibility of the manufacturer or the person under whose responsibility the product is placed on the market.

Nanomaterials
• In Europe nano cosmetic ingredients will be regulated under the Cosmetics Regulation (EC) No 1223/2009.
• The Regulation provides the first regulatory definition of a nanomaterial*
• Requires:
• cosmetic products containing nanomaterials to be notified to the Commission 6 months prior to being placed on the market;
• nanoscale ingredients to be labelled (name of the ingredient, followed by ‘nano’ in brackets);
• if there are concerns over safety of a nanomaterial, the EC will refer it to the Scientific Committee on Consumer Safety (SCCS) for opinion.

Nano-sized Cosmetic Ingredients
• Colorants, antioxidants, antimicrobials, UV filters, supplements (vitamins, minerals);
• Materials include:
• inorganic, organic
• uncoated, coated, doped
• manufactured particles, micelles, liposomes
• R&D on functional nanomaterials
• Used for better dispersibility, antimicrobial or antioxidant properties, effective UV protection, visual clarity of sunscreen formulations, etc;
• A growing range of products worldwide. Only a few products currently in Europe – mainly sunscreens containing nano UV filters.

• Scientific evidence indicates that:
– Nanoparticles may cross membrane barriers, and reach new targets in the body;
– Nanoparticles may interact with biological entities close to the molecular level;
– Exposure to insoluble/ biopersistent nanoparticles may cause concerns over adverse health effects.
Nanomaterials Safety Concerns

Hazard Identification/ Characterisation
• All toxicological endpoints needed for safety evaluation of a (non-nano) cosmetic ingredient should be addressed:
• Dermal/ percutaneous absorption; Toxicokinetics; Acute toxicity; Irritation and corrosivity; Skin sensitisation; Mutagenicity/genotoxicity; Repeated dose toxicity;
• Where appropriate, further studies on Carcinogenicity; Reproductive toxicity; Photo-induced toxicity;
• Additional human data (where available) .
• In vivo and in vitro methods may be used for toxicological evaluation. However, none of the in vitro methods has so far been validated against nanomaterials.
• Only a few elementary in silico models are currently available.
![Page 16: Safety in Cosmetic](https://reader035.fdocuments.us/reader035/viewer/2022080222/62e87e6125e49c79a821ee3b/html5/thumbnails/16.jpg)
www.fda.gov.ir
Safety Assessment
• Any route-to-route extrapolation should be performed on a case-by-case, based on expert judgment of the available scientific information;
• Where data from valid/validated tests are available and uncertainties are not large, there may not be a reason for applying higher margins of safety than those used for a conventional substance;
• Where data are either insufficient or from inadequate tests, a Risk Assessor may consider applying additional uncertainty factors for a nanomaterial;
• Potential persistence and accumulation of nanoparticles should also be considered.
![Page 17: Safety in Cosmetic](https://reader035.fdocuments.us/reader035/viewer/2022080222/62e87e6125e49c79a821ee3b/html5/thumbnails/17.jpg)
www.fda.gov.ir
Nanomaterials Current Challenges
• Lack of validated methods for detection/ characterisation of nanomaterials – especially in cosmetic products and in biological tissues;
• Uncertainties and knowledge gaps in relation to properties, behaviour and toxicological effects of nanomaterials;
• Lack of validated methods for assessment of exposure via dermal, inhalation, ingestion routes;
• Imminent ban on animal testing of cosmetic ingredients in Europe, and the lack of validated alternative testing methods for nanomaterials;
• Difficulties in the use of a category approach to safety assessment of nanomaterials;
![Page 18: Safety in Cosmetic](https://reader035.fdocuments.us/reader035/viewer/2022080222/62e87e6125e49c79a821ee3b/html5/thumbnails/18.jpg)
www.fda.gov.ir
Summary
• The use of CMR substances in cosmetics is prohibited – subject to certain derogations;
• Presence of non-intended trace impurities/ contaminants is only allowed subject to certain provisions;
• The use of nanomaterials will require a thorough assessment of safety, with consideration of nano-aspects.
![Page 19: Safety in Cosmetic](https://reader035.fdocuments.us/reader035/viewer/2022080222/62e87e6125e49c79a821ee3b/html5/thumbnails/19.jpg)

Summary
• Guidance on safety assessment is available. First scientific opinions on nano cosmetic ingredients are available.
• Ban on animal testing will pose a major challenge to safety evaluation of new cosmetic ingredients - especially nanomaterials.
