What is it?
Dimethicone (also called polymethylsiloxane or dimethylpolysiloxane) is a silicon-based polymer used as a lubricant and conditioning agent. It functions as an anti-foaming agent, skin conditioning agent, occlusive and skin protectant. It is found in many cosmetic and hygiene products like nail polish, conditioners, make-up, contact lens solutions, sunscreens, deodorants, and shampoo. Examples of products that contain dimethicone include Aveeno Moisturizing Lotion and Johnson's Baby Cream.
