PEG-24 HYDROGENATED LANOLIN.

Valuable CAS 68648-27-1 / SURFACTANT - EMULSIFYING

PEG-24 Hydrogenated Lanolin, a polyoxyethylenated derivative of hydrogenated lanolin, functions as an effective emollient, emulsifier, and conditioner. It is formulated to enhance skin smoothness and pliability while stabilizing diverse cosmetic emulsions and improving product spreadability.

Emollient Emulsifying Hair Conditioning Skin Conditioning Solubilizer Solvent Surfactant

Science

Mechanism of Action

This ingredient works primarily by forming a soft, non-tacky film on the skin's surface, acting as a lubricant to impart a smooth and soft texture. As a surfactant, it significantly lowers the surface tension between immiscible phases, enabling the creation and stabilization of emulsions. Additionally, its polyethylene glycol structure allows it to serve as a solubilizer and solvent, aiding in the dispersion of other formulation components.

Key findings

  1. 01 Human assays established that PEG Lanolins, including PEG-24 Hydrogenated Lanolin, are nonirritating and nonsensitizing.

Transparency

Dusting Analysis

Not commonly dusted

PEG-24 Hydrogenated Lanolin is effectively incorporated into formulations at levels ranging from 0.2% (e.g., in hair dyes) to 5% (general cosmetic recommendation), ensuring its functional benefits are realized. Its well-documented safety at significantly higher concentrations (up to 100% for irritation studies) indicates it is not an ingredient where minimal inclusion is indicative of 'dusting' for marketing purposes.

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed PEG-24 Hydrogenated Lanolin as safe for use in cosmetic and personal care products. Clinical data confirms its non-irritating nature at concentrations up to 100% and non-sensitizing effects at 10-60%. Potential trace levels of 1,4-dioxane, a byproduct of ethoxylation, are effectively mitigated through standard purification processes.
