PEG-32 DILAURATE.

Valuable CAS 9005-02-1 / SURFACTANT - EMULSIFYING

PEG-32 Dilaurate is a multi-functional non-ionic surfactant and emulsifier, crucial for achieving stable product formulations by blending oil and water components. Beyond its structural role, it provides emollient and moisturizing benefits, enhancing skin softness and aiding the solubilization of other active ingredients.

Science

Mechanism of Action

As a non-ionic surfactant, PEG-32 Dilaurate effectively reduces the interfacial tension between immiscible oil and water phases, thereby creating and stabilizing emulsions. It also acts as an efficient solvent and solubilizer, significantly improving the dissolution of sparingly soluble substances. The dilaurate portion, derived from lauric acid, imparts emollient and moisturizing properties, forming a thin protective film on the skin to mitigate moisture loss and promote a softer feel. Furthermore, it assists in cleansing by facilitating the mixing of water with oils and dirt for easier removal.

Stability

PEG-32 Dilaurate exhibits robust stability and functionality, even in the presence of hard water, with a 10% aqueous solution maintaining a slightly acidic to neutral pH. It is compatible with a broad range of amphoteric, anionic, cationic, and nonionic surfactants, as well as common moisturizers like cetyl alcohol and glycerol.

Sensitization risk Moderate

The CIR Expert Panel considers PEG-32 Dilaurate safe for cosmetic use up to 25%, contingent upon rigorous purification to eliminate potential impurities like 1,4-dioxane and ethylene oxide, which are considered potential human carcinogens and irritants. While typically non-toxic and non-irritating on intact skin, documented cases of sensitization and nephrotoxicity in burn patients treated with PEG-based creams warrant caution for compromised or damaged skin barriers, as PEGs can enhance penetration under such conditions. The FDA monitors its usage and guidelines.
