BUTYL DIETHANOLAMINE.

Valuable CAS 102-79-4 / BUFFERING

A multifunctional alkalizing agent that serves as a precise pH buffer and stabilizer in cosmetic formulations. This water-soluble compound excels at maintaining optimal pH levels while preventing color degradation and enhancing product stability.

pH adjuster buffering agent pigment dispersant color stabilizer

Science

Functions as a potent buffering system that neutralizes acidic components and maintains formulation pH within target ranges, while simultaneously acting as a pigment dispersant to ensure uniform color distribution and prevent oxidative discoloration.
