SODIUM DECYLGLUCOSIDES HYDROXYPROPYLSULFONATE.

Valuable CAS - / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING, SURFACTANT - FOAM BOOSTING, SURFACTANT - HYDROTROPE

SODIUM DECYLGLUCOSIDES HYDROXYPROPYLSULFONATE is a mild, sulfate-free surfactant categorized as a sulfonated alkyl polyglucoside. It functions as an effective cleansing agent, reducing surface tension for optimal product distribution, enhancing foam quality, and acting as an emulsifier and hydrotrope within formulations.

Summary

Mild cleansing agent Surfactant Foam booster Emulsifying agent Hydrotrope

Science

Mechanism of Action

This ingredient operates as a mild cleansing agent by lowering the surface tension of a cosmetic solution, thereby promoting the even spread and enhanced performance of the product. It significantly contributes to the aesthetic and functional properties of formulations by boosting the volume, texture, and stability of foam. Furthermore, it facilitates the blending of oil and water phases as an emulsifying agent and improves the solubility of other sparingly soluble ingredients as a hydrotrope.

Key findings

  1. 01 Human patch testing at a 1% concentration indicated no potential for dermal irritation. This finding was observed for Sodium Laurylglucosides Hydroxypropylsulfonate, a closely related ingredient.
  2. 02 Repeat Insult Patch Testing (RIPT) at a 10% concentration demonstrated no potential for dermal irritation or allergic contact sensitization, based on studies with Sodium Laurylglucosides Hydroxypropylsulfonate.
  3. 03 In microbial protection assays, an 8% concentration showed very good protection against C. albicans, moderate against A. niger, but limited efficacy against P. aeruginosa, using Sodium Laurylglucosides Hydroxypropylsulfonate.
  4. 04 At a 16% concentration, very good microbial protection was observed against a broader spectrum including Pseudomonas aeruginosa, C. albicans, and Aspergillus niger, for Sodium Laurylglucosides Hydroxypropylsulfonate.
  5. 05 Typical usage levels for related ingredients in rinse-off formulations, such as facial cleansers, shampoos, and body washes, span from 15% to 35%.

Sensitization risk Low

While SODIUM DECYLGLUCOSIDES HYDROXYPROPYLSULFONATE itself has not undergone a specific review by the Cosmetic Ingredient Review (CIR) Expert Panel, the Panel has concluded that 'Decyl Glucoside and Other Alkyl Glucosides' are safe when formulated to be non-irritating, a category this derivative is expected to align with. It is considered non-irritating to skin and eyes and is certified 1,4-dioxane-free due to the absence of ethoxylation in its manufacturing. The EPA's Safer Choice Program has certified 'Suga®Nate 100NC' (a commercial form of this ingredient) for use in Safer Choice-certified products. Human patch testing at 1% and repeat insult patch testing at 10% active solutions for Sodium Laurylglucosides Hydroxypropylsulfonate (a closely related compound) showed no dermal irritation or allergic contact sensitization, with in vitro eye irritation studies also indicating practically no ocular irritation potential. Maximum usage levels for related ingredients in rinse-off formulas are up to 35%.
