Quaternium-90 Sepiolite

What is Quaternium-90 Sepiolite?

Quaternium-90 Sepiolite consists of a quaternary ammonium compound, Quaternium-90, adsorbed onto sepiolite, a natural porous clay mineral made of hydrated magnesium silicate. This ingredient falls into the category of conditioning agents for rinse-off hair care products like shampoos and conditioners. It works by forming a positively charged layer on the negatively charged hair surface, which reduces static electricity and improves slip for easier detangling. The sepiolite base enhances absorbency, helping to control excess sebum without drying, while also aiding in viscosity control for better product spreadability. Its structure allows compatibility with various formulations, contributing to lightweight feel and enhanced hair manageability after use. With a profile indicating minimal pore-clogging risk, it supports overall product performance in hair styling.
