PEG-12 GLYCERYL LAURATE.

Valuable CAS 59070-56-3 / SURFACTANT - EMULSIFYING

PEG-12 Glyceryl Laurate is a multi-functional ethoxylated fatty acid ester, primarily employed as an emulsifier to create stable oil-in-water formulations. It additionally imparts conditioning and humectant benefits, contributing to enhanced skin texture and moisture retention across a wide range of cosmetic products.

Summary

Emulsifying Conditioning Humectant Emollient Viscosity Increasing Solubilizing

Science

Mechanism of Action

This ingredient functions by reducing the surface tension between immiscible liquids, effectively binding oil and water phases to produce stable emulsions. Beyond its emulsifying capacity, it acts as a skin and hair conditioning agent, promoting a smoother feel. Its humectant properties draw moisture into the skin, aiding hydration, particularly for dry skin types. It also contributes to product viscosity and can solubilize other lipophilic components within a formulation.

Key findings

  1. 01 The CIR Expert Panel evaluated several PEG-Laurate compounds, including PEG-12 Laurate, concluding their safety for cosmetic use at concentrations up to 25%.
  2. 02 Formulators typically recommend concentrations between 1% and 5% for optimal functional efficacy as an emulsifier, emollient, and co-emulsifying agent.
  3. 03 An ocular irritation study conducted on rabbits demonstrated no irritation at a 1% concentration of PEG-12 Laurate.

Stability

Polyethylene glycols and their derivatives, including this ingredient, exhibit good tolerance and inherent resistance to microbial growth, often negating the need for specific preservation for the raw material itself. It maintains stability under standard storage conditions, with an optimal pH range of 5.0 to 7.0 observed for related PEG-12 Laurate in aqueous solutions.

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEG-2, -4, -6, -8, -12, -20, -32, -75, and -150 Laurate compounds, including PEG-12 Glyceryl Laurate, safe for cosmetic applications at concentrations reaching 25%. While residual 1,4-dioxane, an ethoxylation byproduct, may be present, its levels are controllable through purification processes. Studies on intact skin have not indicated systemic toxicity or sensitization risk, differentiating from observations of kidney toxicity in burn patients treated with high concentrations of PEG-based creams. The FDA has also recognized related PEG Dilaurate ingredients for indirect food contact.
