Valuable / CLEANSING, FOAMING, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, SURFACTANT - HYDROTROPE

Disodium Cocamido PEG-3 Sulfosuccinate is a mild anionic surfactant globally recognized for its gentle cleansing and robust foaming properties. It effectively emulsifies and suspends impurities, allowing for easy rinsing without excessive degreasing, making it suitable for a broad range of skin types.

Summary

cleansing foaming hair conditioning surfactant - foam boosting surfactant - hydrotrope

Science

Mechanism of Action

This ingredient functions primarily by lowering the surface tension of liquids, enabling it to emulsify and suspend oils, dirt, and other impurities from the skin or hair. While it offers a medium cleaning capacity and mild degreasing power, it demonstrates excellent solubilization and viscosity regulation. It also acts as a foam booster and hydrotrope, contributing to stable and rich lather, and provides conditioning benefits to hair.

Stability

Sulfosuccinate ingredients are vulnerable to hydrolysis, particularly under acidic conditions (below pH 5.0), owing to their ester linkage. Additionally, they exhibit sensitivity to elevated temperatures, which necessitates careful consideration for prolonged storage or incorporation into very high-temperature manufacturing processes.

Conflicts

  • Ingredients with pH above 7.0 (for direct compounding)
  • Highly acidic formulations (below pH 5.0)
  • Very high-temperature processes or extended high-temperature storage

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has affirmed alkyl PEG sulfosuccinates, including Disodium Cocamido PEG-3 Sulfosuccinate, as safe for use in current cosmetic practices when formulated to be non-irritating. While it does not pose a sensitization risk, there is a potential for ocular or skin irritation if products are not appropriately formulated. For reference, related Disodium Laureth Sulfosuccinate is suggested not to exceed 1% in products intended for prolonged skin contact, and Disodium Lauryl Sulfosuccinate is used up to 3% in leave-on and 7% in rinse-off applications.
