Disodium Laureth Sulfosuccinate (CAS 36409-57-1) is a celebrated ingredient for its mildness and effective surfactant properties, making it a cornerstone in many personal care and cosmetic formulations. As a leading supplier of this chemical, NINGBO INNO PHARMCHEM CO.,LTD. offers valuable insights into its optimal use. This article provides practical tips and highlights key applications for formulators looking to leverage the benefits of this versatile anionic surfactant.

Key Formulation Considerations

  • pH Compatibility: Disodium Laureth Sulfosuccinate typically has a pH range of 5.5-6.2 in a 10% solution, which is ideal for hair and skin care products. It is stable in hard water, but its solubilizing capabilities for oils and fragrances are limited. If incorporating significant amounts of oil or fragrance, consider using a co-solubilizer like polysorbate 20 or 80.
  • Thickening: Unlike some sulfate surfactants, Disodium Laureth Sulfosuccinate does not thicken well with salt. Formulators will need to utilize non-salt-based thickeners such as carbomers, xanthan gum, or other rheology modifiers to achieve desired viscosity.
  • Synergy with Other Surfactants: This mild surfactant exhibits beneficial synergy with other anionic surfactants, such as Sodium Laureth Sulfate (SLES). By incorporating Disodium Laureth Sulfosuccinate, formulators can significantly reduce the potential for skin irritation associated with stronger surfactants while maintaining excellent foaming and cleansing properties.
  • Concentration Levels: Typical usage levels range from 4% to 40% depending on the product type and desired effect. For products intended for prolonged skin contact, manufacturers often recommend concentrations below 1% or as part of a blend to minimize even potential mild irritation.

Top Applications for Disodium Laureth Sulfosuccinate

  • Sulfate-Free Shampoos and Conditioners: Its gentleness ensures effective cleansing without stripping natural oils, making it perfect for dry or sensitive scalps.
  • Body Washes and Shower Gels: Creates a creamy, luxurious lather that cleanses the skin effectively while leaving it feeling soft and moisturized.
  • Facial Cleansers: Its non-comedogenic properties and mild action make it suitable for all skin types, especially acne-prone or sensitive facial skin.
  • Baby Care Products: The ultra-mild nature is ideal for baby shampoos, washes, and lotions, ensuring the utmost care for delicate skin.
  • Hand Soaps and Detergents: Provides gentle cleansing for hands, preventing dryness and irritation even with frequent use.
  • Industrial Emulsifier: In sectors like coatings and inks, it functions as an emulsifier and wetting agent, aiding in the dispersion of pigments and improving product stability.
