What it is
This ingredient is a silicone-based crosspolymer combining dimethiconol with silsesquioxane and silicate resin structures. It functions as a film former and texture agent, depositing a flexible, cohesive layer that helps pigments and other actives stay evenly distributed on the skin. It is commonly used in tinted mineral sunscreens, skin tints, and foundations to support a smooth, durable finish.
Safety & warnings
Silicone film formers of this type are generally well tolerated, non-sensitizing, and not fragrance allergens. They are usually considered low risk for comedogenicity.
Origin & sourcing
Synthetic silicone polymer.
Questions everyone asks
What is the role of this silicone crosspolymer in tinted sunscreens?
It acts as a film former that helps the product lay down an even, cohesive layer and keeps pigments uniformly distributed for a smooth finish.
Is it a moisturizer?
Not primarily. Its main job is film forming and texture; any conditioning effect is secondary to its structural role.
