POLOXAMER 401

Safety grade: A

Poloxamer 401 is a man-made helper ingredient that acts like a bridge between ingredients that normally don't mix well, such as oil and water. It helps keep cosmetic products smooth, stable, and uniform throughout their shelf life.

This ingredient helps blend oil and water-based components together and reduces the surface tension between substances, creating stable emulsions and improving the texture and consistency of cosmetic formulations.
