About
A silicone-based polymer that provides binding, emulsion stabilization and cleansing properties, this ingredient is considered safe with no EU cosmetic restrictions.
Carboxydecyl Dimethicone is a siloxane polymer with pendant carboxylate groups that functions as an emulsifier, film former, and cleansing agent in cosmetic formulations. In the EU, high分子量 dimethicone polymers (typically >1000 Da) are not subject to restriction under REACH for cosmetic use as they do not penetrate intact skin; no specific entry exists in EU cosmetic Annexes II or III for carboxydecyl dimethicone. The ingredient is evaluated as safe for use in all cosmetic product types including leave-on formulations.
