DICAPRYL SODIUM SULFOSUCCINATE.

Valuable CAS 23524-64-3 / CLEANSING, EMULSION STABILISING, SURFACTANT - CLEANSING, SURFACTANT - HYDROTROPE

Dicapryl Sodium Sulfosuccinate is an anionic surfactant and emulsifier, highly effective at lowering surface tension to blend oils and water. It aids in creating homogeneous formulations, enhancing ingredient dispersion and product application.

Summary

Surfactant/Cleansing Emulsifying Wetting agent Dispersant

Science

Mechanism of Action

This ingredient functions by reducing the surface tension of fluids, allowing non-mixing liquids to combine more effectively. This action improves ingredient penetration, facilitates impurity removal from skin, and increases the water solubility of other cosmetic components.

Key findings

  1. 01 At 0.1% concentration, it significantly reduces surface tension to 25-30 dyn/cm, enhancing miscibility.
  2. 02 A repeated insult patch test (RIPT) at ≤5% revealed no sensitization in 110 individuals, although some erythema was noted, indicating potential cumulative irritancy.

Stability

Stable within a pH range of 4-9; however, alkaline solutions and temperatures above 40°C can cause hydrolysis. Optimal storage is between 5°C and 30°C to prevent decomposition above 80°C.

Conflicts

  • strong acids
  • alkalis
  • oxidizing agents
  • peroxides
  • caustics
  • metals
  • high temperatures (above 80°C)
