PEG-150 LANOLIN.

Valuable CAS 61790-81-6 / SURFACTANT - EMULSIFYING

PEG-150 Lanolin is a polyoxyethylenated lanolin derivative that functions as a multifunctional skin conditioning agent and surfactant. It is engineered to enhance skin softness and smoothness while effectively stabilizing emulsions and mitigating the defatting impact of cleansing agents.

Summary

Emulsifying Surfactant Skin conditioning Emollient

Science

Mechanism of Action

This ingredient operates as a skin conditioning agent by forming an occlusive film on the skin's surface, which lubricates and reduces transepidermal water loss, resulting in a softer and smoother appearance. As a surfactant, it acts as an emulsifier, solubilizer, and wetting agent, lowering surface tension to facilitate the formation and stability of emulsions. Additionally, its mild detergent-like properties help minimize the drying effects of cleansers on both skin and hair.

Stability

Ethoxylated lanolin derivatives like PEG-150 Lanolin demonstrate robust stability across a broad pH range from 2 to 10. For emulsion preparation, it can be seamlessly integrated by melting it with the oil phase or dissolving it directly into the aqueous phase. To preserve its integrity, it should be stored cool in closed containers, and prolonged heating exceeding 80 °C must be avoided.

Sensitization risk Low

The CIR Expert Panel has concluded that PEG-150 Lanolin is safe for use in cosmetics and personal care products at concentrations typically up to 15%. While minute amounts of 1,4-dioxane, a by-product of ethoxylation, may be present, these are controlled through stringent purification methods. This ingredient is not subject to restrictions within the European Union and is recognized by the FDA for various applications, including as an approved active ingredient in certain over-the-counter topical products.
