PEG-32 LAURATE.

Valuable CAS 9004-81-3 / SURFACTANT - CLEANSING

PEG-32 Laurate is a polyoxyethylene glycol derivative that functions as a multi-purpose ingredient in cosmetic formulations. It primarily acts as a surfactant and emulsifier, facilitating the creation of stable emulsions, while also offering emollient properties to soften and hydrate the skin.

Surfactant Emulsifier Solvent Solubilizer Emollient Cleansing

Science

Mechanism of Action

This ingredient functions by reducing the surface tension between disparate substances, thereby enabling the stable mixing of oil and water phases, which is essential for emulsification and effective cleansing. It also serves as a solvent, enhancing the solubilization and uniform dispersion of active compounds. As an emollient, PEG-32 Laurate forms a lightweight, protective film on the skin's surface, which helps to minimize transepidermal water loss and maintain optimal skin hydration.

Max tested
25%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEG-32 Laurate safe for cosmetic use at concentrations up to 25%, provided it is formulated to be non-irritating. Critical considerations include the mandatory removal of potential carcinogenic impurities such as 1,4-dioxane and ethylene oxide through stringent purification. Due to its capacity for increased penetration through compromised skin barriers, its application is not recommended for products intended for infants or individuals with damaged skin.

Verdict

Valuable

PEG-32 Laurate is a versatile ingredient, valuable for its functional roles in emulsification, cleansing, and skin conditioning, but demands rigorous purification and careful formulation to ensure safety, especially avoiding use on sensitive or compromised skin.
