Overview
Butyl benzoate (CAS 136-60-7 ), also known commercially as Anthrapole AZ, is an ester solvent and fixative used across personal care, polymer, and specialty chemical manufacturing.
It functions as a solvent carrier, UV stabilizer auxiliary, and fragrance fixative depending on the application context. In personal care formulations, it acts as an emollient carrier and fragrance fixative.
This material improves skin feel and extends scent longevity in lotions, creams, and color cosmetics. Polymer and plastics processors use it as a carrier solvent for disperse dyes in textile finishing.
It also serves as a plasticizer auxiliary in PVC and synthetic resin systems. In printing and packaging inks, it supports resin dissolution and pigment dispersion, contributing to adhesion and film formation.
The compound functions as a catalyst solvent or reaction medium in specialty chemical synthesis where controlled ester solvency is required. It is supplied as a clear liquid in drum and IBC quantities.
Technical grade is the standard commercial offering, with cosmetic-grade material available for personal care and fragrance applications meeting relevant purity thresholds for industrial use.
Buyers should confirm grade specification against intended application requirements, particularly where skin-contact or regulated end-use is involved to ensure compliance with safety standards.
