What does Polypropylsilsesquioxane do in skincare?

Is Polypropylsilsesquioxane safe in skincare?

Silicone film formers are large molecules that sit on the skin surface. Individual reactions are uncommon but possible, so patch testing is reasonable for sensitive skin.

Is Polypropylsilsesquioxane natural or synthetic?

Polypropylsilsesquioxane is synthetic, belonging to the silsesquioxane family of silicone-based polymers. It is manufactured rather than sourced from plants or animals. Because it is synthetic, it contains no animal-derived material and is typically compatible with vegan formulas.
