PPG-30 LANOLIN ALCOHOL ETHER.

Valuable CAS 68439-53-2 / HAIR CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

PPG-30 Lanolin Alcohol Ether is a polyether derivative of lanolin alcohol, serving as a versatile ingredient in cosmetic formulations. It functions primarily as an emollient, promoting skin softness and smoothness, and as an emulsifier, stabilizing mixtures of oil and water. Additionally, it offers hair conditioning properties.

Science

Mechanism of Action

This ingredient acts as an emollient by forming a subtle film on the skin's surface, which aids in moisture retention, contributing to a softer and smoother complexion. As an emulsifier, it reduces the interfacial tension between immiscible liquids, thereby facilitating the creation and stability of oil-in-water emulsions. Being a polypropylene glycol derivative, its broad range of viscosity and solubility also allows it to function as a solubilizer and solvent within various cosmetic systems.

Key findings

  1. 01 No specific clinical efficacy concentrations for PPG-30 Lanolin Alcohol Ether alone have been identified. However, polyether lanolins, including this compound, are utilized in cosmetics within a concentration span of 0.001% to 15%. Related polyether lanolins and PPG-5 Lanolin Wax, at concentrations up to 7.5%, have demonstrated no irritation or sensitization in human patch tests.
