BABASSU OIL POLYGLYCERYL-4 ESTERS.

Valuable CAS - / SURFACTANT - CLEANSING

A high-performance, PEG-free emollient and surfactant derived from Babassu oil that bridges the gap between effective cleansing and skin barrier preservation. It allows for the seamless integration of nourishing lipophilic components into water-based formulas without leaving a heavy or greasy residue.

Emollient Mild Surfactant Solubilizer Skin-Conditioning Agent

Science

This non-ionic amphiphilic ester works by lowering surface tension to gently lift impurities while simultaneously depositing a biomimetic protective film. It fills the voids between corneocytes in the stratum corneum, mimicking the skin’s natural lipid structure to prevent transepidermal water loss.

Key findings

  1. 01 In-vitro analysis at 10% concentration demonstrated a significant reduction in chemically induced erythema following exposure to harsh surfactants like SLS.
  2. 02 Comparative efficacy testing confirms that levels between 1-5% effectively remove waterproof makeup while maintaining the integrity of the skin's lipid barrier.
  3. 03 In-vivo research on the base Babassu oil indicates over 80% inhibition of inflammation markers, attributed to its high lauric acid content.

Stability

While the raw material is naturally slightly alkaline, it remains stable and functional as a solubilizer across various complex systems. Avoid extreme acidity to prevent potential ester hydrolysis.
