CAPRYLYL/CAPRYL GLUCOSIDE.

Valuable CAS 68515-73-1 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

A plant-derived, non-ionic surfactant and solubilizer known for its exceptional mildness and superior ability to blend essential oils into aqueous formulas. It provides a gentle yet effective cleansing action by removing impurities without compromising the skin's lipid barrier.

Surfactant Cleansing Agent Solubilizer

Science

This molecule features a dual-polarity structure: a hydrophilic glucose head and a hydrophobic C8-C10 fatty acid tail. In aqueous solutions, these molecules aggregate into micelles that trap oil-based debris and pollutants, sequestering them for easy rinsing while simultaneously reducing the surface tension of water to improve spreadability.

Key findings

  1. 01 Dermal absorption is nearly non-existent, with only 0.01% of the active ingredient reaching the viable epidermis and dermis.
  2. 02 Human Repeat Insult Patch Testing (HRIPT) confirmed zero instances of dermal irritation or sensitization when used in finished formulations.

As a surfactant and solubilizer, this ingredient must be used at functional levels (typically 1-10%) to achieve cleansing or stability; levels below 0.5% are generally insufficient for performance and may indicate label 'dusting'.

Stability

While chemically stable across a broad pH range (2.0–12.0), it is supplied at a high alkalinity (pH 11+) and requires precise neutralization to a skin-friendly pH during the formulation process.

Synergies

  • Anionic surfactants
  • Amphoteric surfactants
  • Essential oils

Conflicts

  • None; demonstrates high compatibility across diverse surfactant systems.

Safety
