Scientific Facts
Dimethicone Copolyols belong to a class of chemicals referred to as the silicones. Silicones are resistant to chemical, physical, biological and microbiological degradation within the realm of preparation, storage, and use in cosmetics and personal care products.
Safety Information
The safety of Dimethicone Copolyols has been assessed by the Cosmetic Ingredient ReviewThe Cosmetic Ingredient Review (CIR) was established in 1976 as an independent safety review program for cosmetic ingredients. The CIR Expert Panel consists of independent experts in dermatology, toxicology, pharmacolgy and veterinary medicine. The CIR includes participation by the U.S. Food & Drug Administration and the Consumer Federation of America. (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that the Dimethicone Copolyols were safe for use as cosmetic ingredients. In 2003, as part of the scheduled re-evaluation of ingredients, the CIR Expert Panel considered available new data on Dimethicone Copolyols and reaffirmed the above conclusion.
CIR Safety Review: These polymers were, at most, slightly toxic when administered orally or dermally in a single dose. Dimethicone Copolyols were not primary skin or ocular irritants and gave no evidence of subchronic oral toxicity. Clinical studies showed that the Dimethicone Copolyols were neither primary skin irritants nor sensitizers when tested at a 100% concentration. Dimethicone Copolyols may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Regulation of the European UnionUnder the general provisions of the cosmetics regulation of the EU, ingredients appearing on the following function-specific annexes must comply with the listed restrictions and/or specifications: colorants (Annex IV), preservatives (Annex V), UV filters (Annex VI) and other ingredients with specific concentration limits and/or other restrictions (Annex III). Ingredients specifically prohibited from use in cosmetic products are listed in Annex II. Other ingredients listed in the EU cosmetic ingredient database (CosIng) may be used without restrictions..

More Scientific Information
Dimethicone Copolyol is a polymerA naturally occurring or synthetic molecule made up of repeating units called monomers. of dimethylsiloxane with polyoxyethylene and/or polyoxypropylene side chains. The numbers indicate the average number of moles of ethylene oxide and/or propylene oxide. In cosmetics and personal care products, Dimethicone Copolyols function primarily as surfactants – emulsifying agents. They are also used to improve wetting characteristics of skin lotions, shave formulations, aerosol shave creams, and shampoos.
