PPG-15 STEARATE.

Valuable CAS 25190-52-7 / SKIN CONDITIONING - EMOLLIENT

PPG-15 Stearate is a versatile non-ionic emollient highly valued for its skin-softening and moisturizing properties, achieved through an occlusive film. It significantly boosts the solubility of challenging active ingredients and acts as a penetration enhancer for optimized delivery within formulations.

Summary

emollient solubilizer solvent penetration enhancer conditioner

Science

Mechanism of Action

This ingredient functions as an effective non-ionic emollient, delivering skin-softening, greasing, and smoothing effects while preventing moisture loss through occlusive action. It excels as a solubilizer for sparingly soluble components such as fragrance compounds, plant extracts, and crystalline UV filters. Furthermore, PPG-15 Stearate acts as a carrier and penetration enhancer, capable of forming liquid crystal structures with specific emulsifiers to improve active ingredient dissolution, control release, and protect delicate molecules.

Key findings

  1. 01 A study demonstrated that PPG-15 Stearate at 2.5% notably increased the skin permeation of a psoriasis medication in pig ear skin, outperforming isopropyl myristate. Higher concentrations of 5% and 10% resulted in decreased permeation, suggesting an inverse relationship between concentration and penetration enhancement.

Stability

PPG-15 Stearate demonstrates robust chemical stability, maintaining its activity and integrity across a wide pH range from 2 to 10, even under challenging environmental conditions.

Synergies

  • When combined with selected emulsifiers, it can form liquid crystal structures (oleosomes) at low concentrations, which can improve the dissolution of poorly water-soluble active ingredients, control their release, and protect/facilitate the transport of fragile molecules.

Max tested
25%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PPG-15 Stearate is safe for use in cosmetics at concentrations up to 25%. While undiluted forms were slightly irritating to rabbit skin, common use concentrations (1% to 18%) are generally well-tolerated. A small subset of individuals may experience minor skin irritation or allergic reactions like hives or itching.
