CYCLOPENTASILOXANE
Safety grade: C**
Cyclopentasiloxane is a lightweight silicone ingredient that feels silky and smooth on the skin. It's commonly used in beauty products because it spreads easily and dries quickly without leaving a greasy residue.
This ingredient makes products feel luxurious and lightweight while helping condition skin and hair, improving product spreadability, and allowing other ingredients to absorb smoothly.
