4-T-BUTYL STYRENE.

Avoid / NOT REPORTED

A reactive monomeric building block used primarily in polymer synthesis rather than as a direct skincare ingredient. When polymerized into copolymers, it contributes to film-forming and oil-absorbing properties in cosmetic formulations, though its monomeric form offers no inherent skin benefits.

Summary

monomer polymer building block
