CAPRYLYL/CAPRYL WHEAT BRAN/STRAW GLYCOSIDES.

Valuable CAS - / CLEANSING, EMULSION STABILISING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING, SURFACTANT - FOAM BOOSTING

A sophisticated, plant-derived non-ionic surfactant and solubilizer that enables the seamless integration of essential oils and lipophilic actives into water-based formulas. Derived from upcycled wheat straw and bran, it serves as a high-performance, PEG-free alternative for maintaining formula clarity and stability.

non-ionic surfactant solubilizer cleansing agent emulsion stabilizer

Science

This ingredient functions by utilizing a hydrophilic sugar-based head and a lipophilic fatty tail to reduce surface tension. It organizes into micelles that encapsulate oils, allowing them to disperse evenly in aqueous systems. Unlike traditional anionic surfactants, its large polar head prevents it from disrupting the skin's lipid bilayer, ensuring deep cleansing without compromising barrier integrity.

Key findings

  1. 01 Human patch testing at a 2.0% concentration confirms excellent skin compatibility and a non-irritating profile, specifically for sensitive skin types.
  2. 02 Research indicates that concentrations between 0.5% and 5.0% achieve superior solubilization of essential oils like Thyme and Rosemary while maintaining low particle size and high rheological stability.

While primarily a functional solubilizer, using this ingredient below 0.5% in formulas containing high oil loads may result in emulsion instability or 'dusting'—where the ingredient is listed for label appeal but lacks the concentration to perform its chemical role.

Stability

Highly resilient to thermal processing up to 80°C and maintains stability across a broad physiological pH range.

Synergies

  • Essential oils
  • Lipophilic vitamins
  • Fragrance compounds

Conflicts

  • Highly acidic environments below pH 3.0 (risk of glycosidic bond hydrolysis)
  • Excessive electrolyte/salt concentrations (may diminish foam density)
