SODIUM C12-14 PARETH-3 SULFATE.

Questionable / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sodium C12-14 Pareth-3 Sulfate is a functional surfactant, frequently incorporated into cosmetic formulations as a cleansing agent and emulsifier. It is designed to facilitate the effective removal of impurities and blend immiscible liquid phases.

Summary

Surfactant Cleansing Emulsifying

Science

Mechanism of Action

This ingredient operates by significantly reducing the surface tension of a liquid, enabling substances like oil and water to combine more readily. Its primary action involves forming micelles, which are molecular structures that entrap dirt and oil particles, thereby allowing their efficient detachment and rinsing from skin and hair surfaces.

A specific Cosmetic Ingredient Review (CIR) assessment for Sodium C12-14 Pareth-3 Sulfate has not been conducted. However, related 'pareth' and sulfate ingredients have undergone safety evaluations. The European Chemicals Agency (ECHA) classifies a chemically analogous substance, Alcohols, C12-14, ethoxylated, sulfates, sodium salts, with GHS statements indicating it 'Causes skin irritation' (H315) and 'Causes serious eye damage' (H318). Despite these classifications, manufacturers commonly formulate this ingredient in combination with milder surfactants to improve dermal tolerance, adhering to stringent consumer safety standards.

Verdict

Questionable

While effective for cleansing and emulsifying across normal and oily skin types, the ingredient's classification for moderate skin and serious eye irritation, coupled with an unknown comedogenicity, advises cautious consideration for its inclusion in precision skincare, particularly for individuals with dry or sensitive skin.
