DISODIUM C12-14 SEC-PARETH-12 SULFOSUCCINATE.

Valuable / CLEANSING, SKIN CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, SURFACTANT - HYDROTROPE

Disodium C12-14 Sec-Pareth-12 Sulfosuccinate is a multifunctional, mild surfactant engineered to optimize cleansing efficiency and enhance product aesthetics. It enables the uniform blending of oil and water, contributing to a smoother texture and supporting the generation of gentle, effective foam.

Surfactant Cleansing Agent Skin Conditioning Agent Foam Booster Hydrotrope

Science

Mechanism of Action

This ingredient functions primarily as a surfactant, cleansing agent, foam booster, and hydrotrope. It effectively lowers the surface tension in cosmetic formulations, allowing immiscible liquids like oil and water to combine and distribute evenly, thereby improving product texture and spreadability. Furthermore, it assists in creating mild, stable foams crucial for efficient impurity removal without burdening the skin, and enhances the solubility of other substances in aqueous solutions.

Key findings

  1. 01 A 3% solution (containing approximately 1.2% active Disodium C12-14 Pareth-2 Sulfosuccinate) was found to be minimally irritating to unrinsed guinea pig eyes and non-irritating when eyes were rinsed.
  2. 02 A 10% aqueous solution (containing approximately 4% active Disodium C12-14 Pareth-2 Sulfosuccinate) did not induce primary or cumulative irritation when tested on guinea pig skin.
  3. 03 A related ingredient, Disodium Laureth Sulfosuccinate (at 1.68% active in a trade name mixture), was classified as a primary ocular irritant in rabbits, but did not cause clinically significant irritation or allergic contact dermatitis in human subjects.

Dusting Analysis

Not commonly dusted

As a surfactant primarily used for cleansing and formulation stability, this ingredient is typically incorporated at functional percentages rather than 'dusted' as a highly concentrated active.

Stability

Based on a related sulfosuccinate, optimal stability is observed within a pH range of 6.5 to 7.5 in a 5% aqueous solution. It is susceptible to hydrolysis in highly alkaline or acidic environments but maintains stability in hard water conditions.

Conflicts

  • Acidic media (potential for hydrolysis)

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel concluded that alkyl PEG sulfosuccinates, including Disodium C12-14 Sec-Pareth-12 Sulfosuccinate, are safe in current practices of use and concentration when formulated to be non-irritating. For all ethoxylated ingredients, the SCCS recommends a target level of less than or equal to 10 ppm of 1,4-dioxane in finished cosmetic products to be progressively achieved. This ingredient is listed in the precisionFDA database.
