LAURYL GLUCOSIDE.

Valuable CAS 110615-47-9 / CLEANSING, SURFACTANT - CLEANSING

Lauryl Glucoside is a naturally derived, non-ionic surfactant and cleansing agent, primarily sourced from corn sugar and coconut or palm oils. It effectively lifts and removes dirt and oil while producing a stable, moderate to high amount of foam, enhancing the overall cleansing experience.

Summary

Cleansing Surfactant Foaming Agent Emulsifying

Science

Mechanism of Action

This ingredient functions by significantly lowering the surface tension between liquids, which allows for the efficient emulsification and removal of impurities like dirt, oil, and debris from the skin or hair. As a foaming agent, it generates stable lather and can also contribute to skin conditioning, especially when combined with other alkyl glucosides. In hair care, it cleanses effectively without stripping natural oils.

Key findings

  1. 01 Demonstrates efficacy in facial cleansers at concentrations between 10-20%.
  2. 02 Effective in shampoos and body washes within concentrations of 15-30%.
  3. 03 Permitted for use up to 40% in rinse-off products.
  4. 04 A 5% concentration is the highest reported for leave-on products, showing no sensitization reactions.
  5. 05 Clinical studies indicate only slight irritation, at most, when used with other glucosides at 1-2% in patch and soap chamber tests.

Stability

Lauryl Glucoside exhibits high stability across a broad pH range of 2.5 to 12.5. However, it may undergo slow hydrolysis in strong aqueous acids (pH 1 or lower, or potentially pH 2 for extended periods). Its high intrinsic pH (11.5-12.5 as supplied at 50% solid content) often negates the need for additional preservatives within the ingredient itself. Storage below 38°C may lead to crystallization or sedimentation, necessitating gentle heating and stirring to achieve homogeneity before use. Its high viscosity also contributes to the final product's texture and stability.

Synergies

  • Enhances foam depth and skin conditioning properties when combined with other alkyl glucosides (e.g., decyl glucoside, coco-glucoside).
  • Aids in viscosity build-up of the final product due to its inherent high viscosity.

Conflicts

  • Risk of hydrolysis in strong aqueous acid (pH 1 or lower, potentially pH 2 for extended durations).

Safety

Safety Profile

CIR Status
Safe as used
Max tested
40%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed Lauryl Glucoside and other alkyl glucosides, concluding they are safe under current practices of use and concentration when formulated to be non-irritating. A maximum of 40% is permitted for general product use, while the highest reported leave-on concentration with dermal contact is 5%, at which no sensitization reactions have been reported. It is generally considered safe under EU cosmetic regulations and is listed by the FDA Voluntary Cosmetic Registration Program (VCRP).
