Valuable CAS 56388-44-4 / CLEANSING, FOAMING, SKIN CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, SURFACTANT - HYDROTROPE

Disodium Lauramido PEG-2 Sulfosuccinate is a mild, anionic surfactant widely used for its effective cleansing and foam-boosting properties. It delicately removes impurities and oils from the skin, enhancing product texture without causing harshness.

Summary

Surfactant Cleansing Agent Foam Booster Hydrotrope Emulsifier

Science

Mechanism of Action

This ingredient functions primarily as a surfactant by significantly lowering the surface tension between water and lipid components, such as oils and dirt. This action allows for the emulsification and suspension of these particles, enabling their effortless removal during rinsing. Additionally, it contributes to the sensory experience by boosting foam volume and stabilizing emulsions within formulations.

Stability

As an ester, Disodium Lauramido PEG-2 Sulfosuccinate is prone to hydrolysis in highly acidic or alkaline conditions. Maintaining a pH within the optimal range of 5.0 to 7.0 is crucial for its stability and effectiveness. It exhibits full compatibility with anionic, non-ionic, and amphoteric surfactants.

Synergies

  • Compatible with anionic, non-ionic, and amphoteric surfactants

Conflicts

  • Compounding directly with ingredients at a pH above 7.0
  • Formulation in strongly alkaline or acidic media due to hydrolysis risk

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated alkyl PEG sulfosuccinates, including this compound, concluding their safety under current use practices and concentrations when formulated to be non-irritating. While potential for ocular and skin irritation exists at high concentrations or with prolonged contact, dermal penetration is deemed unlikely due to its substantial molecular size and polarity. No specific maximum concentration for Disodium Lauramido PEG-2 Sulfosuccinate has been explicitly defined, though a related ingredient, Disodium Laureth Sulfosuccinate, is generally considered safe by the FDA.
