PEG-20 LANOLATE.

Valuable CAS 68459-50-7 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-20 Lanolate is a highly stable, water-soluble derivative of lanolin, functioning as a multifaceted skin conditioning agent. It efficiently hydrates the skin as a humectant and softens its texture as an emollient, while also acting as an effective emulsifier to blend oil and water components seamlessly.

Science

Mechanism of Action

This ingredient operates by leveraging its amphiphilic structure, possessing both lipophilic and hydrophilic segments, to significantly reduce interfacial tension between immiscible phases, enabling the formation of stable emulsions. Beyond its emulsifying capabilities, PEG-20 Lanolate actively conditions the skin, enhances epidermal softness, and functions as a humectant to attract and retain essential moisture, thus preventing dryness and minimizing the defatting effects often associated with cleansing agents.

The Cosmetic Ingredient Review Expert Panel affirms its safety for cosmetic use, demonstrating low irritation and sensitization potential up to 60%. While trace amounts of 1,4-dioxane, a by-product of ethoxylation, may be present, these are controllable through purification processes. It is crucial to avoid use on severely damaged skin due to potential absorption concerns and kidney toxicity risks observed in specific, extreme cases.
