DISODIUM C12-14 SEC-PARETH-9 SULFOSUCCINATE.

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

DISODIUM C12-14 SEC-PARETH-9 SULFOSUCCINATE is a versatile anionic surfactant that effectively lowers surface tension, allowing oil and water to integrate. This property makes it an efficient cleansing agent, aiding in the removal of impurities, and it also functions as a foam booster, emulsifier, and hydrotrope in cosmetic formulations.

Summary

Skin Conditioning Cleansing Agent Surfactant - Foam Boosting Surfactant - Hydrotrope Emulsifier

Science

Mechanism of Action

As a surfactant, DISODIUM C12-14 SEC-PARETH-9 SULFOSUCCINATE operates by significantly reducing the surface tension of liquids, thereby facilitating the mixing of substances that typically do not combine, such as oil and water. This action is pivotal for its cleansing efficacy, enabling the thorough removal of fats and soil particles from the skin. Furthermore, it enhances foam generation, stabilizes oil-in-water mixtures as an emulsifier, and improves the solubility of other ingredients in water as a hydrotrope.

Key findings

  1. 01 Studies on related sulfosuccinates (Disodium Laureth Sulfosuccinate) at 5% and 10% in aqueous solutions indicated no induction of skin irritation in both healthy subjects and those with dermatitis.
  2. 02 Conversely, a separate study classified a 10% concentration of Disodium Laureth Sulfosuccinate as a mild skin irritant in healthy individuals.
  3. 03 A human cumulative skin irritation study predicted that a 0.168% concentration of Disodium Laureth Sulfosuccinate in a trade name mixture could be a mild skin irritant during normal use.
  4. 04 High concentrations of related sulfosuccinates, specifically 25% and 1.68% active matter, were classified as posing a risk of serious ocular damage or as primary ocular irritants in rabbit models.

Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that alkyl PEG sulfosuccinates, including DISODIUM C12-14 SEC-PARETH-9 SULFOSUCCINATE, are safe under current usage practices and concentrations, provided they are formulated to be non-irritating. Concentrations up to 10% have been reported for related sulfosuccinates in cosmetic products. It is important to note that the ingredient in its concentrated, liquid form has the potential to cause irritation to skin and eyes, necessitating careful formulation to mitigate this risk.
