Valuable CAS 68411-57-4 / CLEANSING, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, SURFACTANT - HYDROTROPE

Disodium Cocoamphodipropionate is an amphoteric surfactant derived from coconut oil, celebrated for its gentle cleansing and foam-boosting properties. It enhances the mildness and skin feel of formulations, helping to maintain optimal skin condition.

Summary

Mild Cleansing Agent Amphoteric Surfactant Foam Booster Irritation Mitigator Solubilizer Emulsifier

Science

Mechanism of Action

This ingredient functions by significantly reducing the surface tension of liquids, facilitating the emulsification of water with oil and dirt for effective rinsing. It also acts as an efficient foam booster, increasing the volume and stability of lather. Beyond cleansing, it helps to mitigate the potential irritation caused by other surfactants and provides valuable solubilizing and emulsification capabilities.

Key findings

  1. 01 A case report documented worsened dermatitis and positive patch test reactions at 0.1-1% aqueous solutions in a 28-year-old woman with eczema, following exposure to a contact lens solution containing 38-40% Disodium Cocoamphodipropionate. This highlights a potential for sensitivity in individuals with compromised skin or at elevated concentrations.

Stability

Disodium Cocoamphodipropionate exhibits robust hydrolytic stability and demonstrates unusual tolerance and compatibility with high-electrolyte and alkaline formulations. It maintains stability across a wide pH range and can assist in solubilizing other surfactants within these systems.

Synergies

  • Reduces irritation potential when co-formulated with anionic surfactants
  • Enhances foaming performance when co-formulated with anionic surfactants

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Moderate

The CIR Expert Panel concluded that Disodium Cocoamphodipropionate is safe for cosmetic use, a finding reaffirmed in 2006. While generally well-tolerated, rare instances of skin sensitivity have been reported. A specific case involved a 28-year-old woman with a history of eczema who experienced worsened dermatitis from a contact lens solution containing 38-40% of the ingredient, with positive patch test reactions observed at 0.1-1% aqueous solutions. The maximum reported 'as used' concentration serves as the basis for CIR's safety assessment.
