Overview
Phenoxyisopropanol (CAS 770-35-4 ), also sold as Propylene Glycol Phenyl Ether, is a slow-evaporating glycol ether solvent with broad utility across coatings, personal care, and adhesive formulations.
Its low volatility and coupling efficiency make it a practical choice for formulators managing solvent balance and preservation performance simultaneously. In waterborne coatings and architectural paints, it functions as a coalescing aid.
It acts as a coupling solvent, improving film formation without the regulatory burden of conventional glycol ethers. Personal care formulators incorporate it as both a solvent carrier and a preservative booster.
This is particularly useful in rinse-off and leave-on products where broad-spectrum antimicrobial support is required. Adhesive and sealant manufacturers use it to adjust viscosity and improve substrate wetting in water-based systems.
It also serves as a co-solvent in industrial cleaning formulations where controlled evaporation rate and compatibility with surfactant systems are priorities. The material is supplied as a clear liquid in drum and IBC quantities.
It is available in cosmetic-grade and technical-grade specifications to meet the sourcing requirements of both personal care and industrial buyers. Purity levels are typically 99% or higher for cosmetic applications.
