PEG-5 PENTAERYTHRITYL ETHER.

Valuable / SKIN CONDITIONING - EMOLLIENT

PEG-5 PENTAERYTHRITYL ETHER is a versatile polyethylene glycol (PEG) derivative valued for its skin-conditioning properties. It functions as an emollient to smooth and soften the skin, and as a humectant to enhance moisture retention. Additionally, it stabilizes cosmetic formulations by acting as an effective emulsifier.

Science

Mechanism of Action

This ingredient operates on multiple fronts to benefit both skin and product stability. On the skin, it primarily functions as an emollient, forming a protective film that imparts a smooth and soft feel to the skin's surface. As a humectant, derived from polyethylene glycol, it actively attracts and binds water molecules, creating hydrogen bonds to reduce trans-epidermal water loss and significantly boost hydration, which is particularly advantageous for dry skin. In cosmetic formulations, PEG-5 PENTAERYTHRITYL ETHER acts as an emulsifier and texturizing agent, ensuring the homogenous mixing of oil and water components and contributing to the desired product consistency.

Stability

Formulations incorporating this ingredient must be meticulously designed to be non-irritating. Furthermore, strict adherence to appropriate removal procedures is essential to mitigate potential contamination from 1,4-dioxane and unreacted ethylene oxide residues.

Conflicts

  • Should not be used in cosmetic products applied to damaged or compromised skin, as PEGs have demonstrated potential for systemic toxicity and increased sensitization under such conditions.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed PEG-5 PENTAERYTHRITYL ETHER, along with other alkyl PEG/PPG ethers, concluding it is safe under current practices of use and concentration when formulated to be non-irritating. The US Food and Drug Administration (FDA) has also approved its limited use in food. It is generally understood that its larger molecular structure compared to other PEG ethers reduces its likelihood of significant skin penetration. However, a critical caveat is to avoid its application on damaged skin due to documented concerns regarding systemic toxicity and enhanced sensitization of PEGs on compromised epidermal barriers.
