Dimethicone/PEG-10/15 Crosspolymer

A self-emulsifying surfactant, which means that it can help facilitate the formation of water-in-silicone emulsions. This results in lightweight formulas with a soft finish. It can also act as a film-former and thickener.

Overview

Dimethicone/PEG-10/15 crosspolymer is a self-emulsifying surfactant, which means that it can help facilitate the formation of a water-in-silicone emulsion or cream. Skincare products with this ingredient tend to be lightweight and luxurious upon application and leave a soft, non-greasy finish.

Dimethicone/PEG-10/15 crosspolymer can also act as a film-former due to its ability to form networks using its polymer character. These networks act as a water-resistant barrier between the skin and the external environment, so things like water and sweat will not easily rinse the product away.

Also, this ingredient can be used to increase and control viscosity by utilizing the network behavior, which takes up space in the product – thus, thickening the product overall.
