Description

Polysilicone-20 is a silicone chemical compound, a copolymer of a complex mixture of esters formed from the reaction of PEG-8 Dimethicone and Polysorbate 20, Polysorbate 80 crosslinked with Succinic Acid and Maleic Acid.

Silicones have high chemical stability but low biodegradability and high bioaccumulation potential.

Safety.
It is an ingredient that has a high bioaccumulation and persistence, however in cosmetic use this ingredient is considered safe.

What it is used for and where
Cosmetics
Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
