MEROXAPOL 178.

Insufficient Data CAS 9003-11-6 / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Meroxapol 178 is a versatile block copolymer functioning primarily as a surfactant and emulsifier in skincare formulations. It efficiently reduces surface tension, aiding in the cleansing of skin by emulsifying oils and impurities, while also stabilizing oil-in-water mixtures.

Summary

Cleansing Agent Emulsifier

Science

Mechanism of Action

Meroxapol 178 operates by lowering the surface tension of liquids, which facilitates the emulsification of oils and dirt on the skin, allowing them to be rinsed away with water. Concurrently, it stabilizes complex cosmetic formulations by forming and maintaining homogenous dispersions of immiscible liquids like oil and water.

Stability

Meroxapol 178 exhibits solubility in both aqueous and oil-based systems. While optimal pH ranges are not explicitly defined, related poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers demonstrate stability at low pH (e.g., pH 5), suggesting potential for acidic formulation compatibility.

Verdict

Insufficient Data

While Meroxapol 178 effectively performs as a surfactant and emulsifier, critical comprehensive safety data for its direct cosmetic application, including irritancy and comedogenicity, remains insufficient.
