DISODIUM C12-14 PARETH-4 SULFOSUCCINATE.

Valuable / CLEANSING, SOLVENT, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING

DISODIUM C12-14 PARETH-4 SULFOSUCCINATE is a versatile anionic surfactant, engineered for effective yet gentle cleansing in precision skincare. It functions by emulsifying oils and dirt, facilitating their removal from the skin while simultaneously boosting foam and enhancing the mildness of cleansing formulations.

Summary

cleansing agent surfactant foam boosting hydrotrope

Science

Mechanism of Action

As an anionic surfactant, this ingredient operates by significantly reducing the surface tension of water, which allows it to efficiently emulsify oils and impurities, thereby enabling them to be easily lifted from the skin or hair and rinsed away. Beyond its primary cleansing action, it also serves as an effective foam booster and contributes to improving the skin compatibility of potentially harsher anionic surfactants, such as Sodium Laureth Sulfate.

Key findings

  1. 01 Clinical evaluations on closely related compounds offer insights into its dermatological impact. A human cumulative skin irritation study using a trade mixture with 0.168% active Disodium Laureth Sulfosuccinate (a related compound) predicted it would be a mild skin irritant with typical use.
  2. 02 Conversely, another human study found that a trade name mixture containing 1.68% active Disodium Laureth Sulfosuccinate (a related compound) did not induce clinically significant irritation or any signs of allergic contact dermatitis in normal subjects.
  3. 03 An animal study indicated that Disodium C12-14 Pareth-2 Sulfosuccinate (a closely related compound, approximately 40% active in raw material) caused minimal eye irritation in guinea pigs when tested at a 3% solution in physiological saline.
  4. 04 For its functional cleansing and foaming properties, a recommended use level for Disodium Laureth Sulfosuccinate (a related compound) spans from 4% to 40% depending on the desired effects in the final product.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that related alkyl PEG sulfosuccinates are safe under current usage practices and concentrations, provided they are formulated to be non-irritating. The assessment highlights a potential for ocular and skin irritation, which is dependent on concentration and the overall formulation. There is no specific SCCS opinion or FDA cosmetic status for this precise ingredient.
