What Is PCA Dimethicone?
PCA dimethicone is a synthetic emollient skin care ingredient created by combining dimethicone and pyrrolidone carboxylic acid, an amino acid-derived ingredient that’s part of skin’s natural moisturizing factor. It’s used in products for its hydrating benefits as well as its ability to impart a silky, smooth feel when applied to skin.
This siloxane polymer’s an emollient ingredient, meaning that it helps boost skin’s hydration by creating a layer over skin to reduce transepidermal water loss and help ensure a supple feel.
According to suppliers, PCA dimethicone is most commonly used in leave-on moisturizing products, like moisturizers, in concentrations between 0.25%-10.0%. It does not present safety or sensitization concerns for skin.
