PEG-6 DILAURATE.

Valuable CAS 9005-02-1 / SURFACTANT - EMULSIFYING

PEG-6 DILAURATE is a polyethylene glycol derivative that acts as a multi-functional ingredient in skincare, primarily as a surfactant and emulsifying agent. It facilitates the stable integration of immiscible phases, such as oil and water, within formulations. Furthermore, it contributes humectant properties, aiding in skin hydration, and serves as a solvent for other active ingredients.

Science

Mechanism of Action

This ingredient functions by reducing the interfacial tension between disparate liquid components, allowing them to form stable emulsions. Its molecular structure contains both lipophilic (oil-attracting) and hydrophilic (water-attracting) parts, enabling it to bridge oil and water phases effectively. As a derivative of polyethylene glycol, it can also attract and bind moisture within the skin, acting as a humectant. Additionally, it helps to dissolve and carry other substances, making it a valuable solvent and aiding in the cleansing process by enabling water to mix with and rinse away oils and dirt.

Stability

Polyethylene glycols and their derivatives are highly favored in cosmetic formulations due to their wide range of viscosity and solubility profiles, alongside good skin tolerance. The physical consistency of PEG derivatives generally transitions from liquid to solid as their degree of polymerization, and thus molar mass, increases; PEGs with a mean molar mass up to 600 g/mol are typically liquid. No specific optimal pH range for PEG-6 DILAURATE's stability has been identified in the research, though a related ingredient, PEG-80 Sorbitan Laurate, is recommended for a pH range of 6.0-7.0.

Max tested
25%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed that PEG-6 DILAURATE, along with several other PEG Dilaurate derivatives, is safe for use in cosmetic and personal care products at concentrations up to 25%. The FDA has also approved certain PEG Dilaurate ingredients for indirect food contact as components in food packaging materials. While concerns exist regarding potential impurities like 1,4-dioxane, a byproduct of the ethoxylation process, manufacturers typically implement purification steps to mitigate these risks. Studies have indicated that while PEGs can be absorbed through damaged skin (e.g., in burn patients), leading to potential systemic toxicity or sensitization, there is no evidence of such effects when applied to intact skin. This ingredient is permissible for use in cosmetics within the European Union under the general provisions of the Cosmetics Regulation.
