PPG-10-CETEARETH-20.

Valuable CAS - / SURFACTANT - EMULSIFYING

PPG-10-Ceteareth-20 is a precision ingredient primarily serving as an emulsifier and surfactant, expertly blending oil and water phases for stable cosmetic formulations. It also offers solubilizing and solvent capabilities, while concurrently acting as an emollient to enhance skin hydration and texture.

Summary

Emulsifying Surfactant Solubilizer Solvent Emollient Penetration Enhancer

Science

Mechanism of Action

This compound functions as an amphiphilic agent, utilizing its dual lipophilic and hydrophilic segments to effectively lower the interfacial tension between disparate liquids, thereby stabilizing emulsions. Applied topically, it establishes a subtle emollient film that supports the skin's moisture barrier, preventing dehydration and promoting a smoother, softer feel. Its additional roles as a solvent and solubilizer aid in the uniform distribution of other ingredients, and it holds potential as a penetration enhancer for co-formulated active substances.

Stability

While its structural analogue, Ceteareth-20, exhibits notable resilience in the presence of electrolytes and hard water, it demonstrates sensitivity to acidic conditions, under which it undergoes hydrolytic degradation.

Conflicts

  • Co-formulation with cetearyl alcohol is observed to significantly elevate the comedogenicity rating of the related Ceteareth-20, from a baseline of 2 (moderately low) to a considerably higher 4 (fairly high).

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The CIR Expert Panel has determined that 131 alkyl PEG/PPG ethers, including PPG-10-Ceteareth-20, are safe for cosmetic application when formulated to be non-irritating. A crucial caveat is its contraindication on compromised skin, substantiated by research indicating kidney damage from polyethylene glycol (PEG) application on burn patients. There are historical concerns regarding trace carcinogenic byproducts, ethylene oxide and 1,4-dioxane, stemming from ethoxylation; however, contemporary, stringent purification processes are designed to effectively eliminate these risks. For closely related compounds, recommended concentrations for Ceteareth-20 are typically 0-6%, not exceeding 30%, and for PPG-5-Ceteth-20, concentrations up to 20% are considered safe.
