AVOCADO OIL PROPYLENE GLYCOL ESTERS.

Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A specialized ester derived from avocado oil that bridges the gap between botanical nourishment and formulation science. It serves as a dual-action ingredient, providing the skin with essential lipids while ensuring the structural integrity of complex emulsions.

Summary

emollient emulsifying surfactant skin conditioning

Science

Mechanism of Action

This ingredient operates as a biomimetic emollient by integrating into the stratum corneum's lipid matrix. It fills the voids between corneocytes to smooth the skin texture and delivers high concentrations of oleic and linoleic acids, which mimic the skin's natural barrier to significantly lower transepidermal water loss (TEWL). Additionally, it reduces interfacial tension between oil and water phases to stabilize formulations.

Key findings

  1. 01 Structural analog assessments (Propylene Glycol Stearate) demonstrate zero significant irritation in 24-hour patch tests and no sensitization at concentrations up to 2.5%.
  2. 02 Recent 2024 pharmacological data confirms the parent avocado lipid's high efficacy in anti-aging and accelerated wound healing due to its specific fatty acid profile.
