Usage

General Description

POLYMETHYLOCTADECYLSILOXANE is a silicone-based polymer that is commonly used as an emollient and moisturizing agent in various skincare and cosmetic products. It is a type of silicone fluid that helps to smooth and soften the skin, while also providing a protective barrier against environmental aggressors. This chemical is also known for its ability to improve the spreadability and texture of formulations, making it a popular ingredient in lotions, creams, and serums. Additionally, POLYMETHYLOCTADECYLSILOXANE is often included in hair care products to enhance shine and manageability. Despite its widespread use, there is limited evidence on its long-term safety and potential health impacts, so caution is advised when using products containing this chemical.
