What it is
A synthetic silicone polymer made by crosslinking silicone chains with polyglycerol and lauryl groups. It is a solid or semi-solid ingredient used to improve the texture and stability of cosmetic formulas.
How it works
When applied, it spreads into a uniform, flexible film that smooths the skin's surface. It also helps keep oil and water ingredients mixed together, preventing separation in products like foundations and sunscreens.
Pros
Silky texture
Gives products a luxurious, velvety feel that reduces friction during application.
Wear longevity
Helps makeup and sunscreen stay in place longer by forming a flexible film.
Cons and cautions
Environmental persistence
Silicones can accumulate in the environment and are not readily biodegradable.
Potential heaviness
In high amounts, it may feel too rich for very oily or acne-prone skin.
Best for
- People who want a smooth, blurring effect on skin
