SODIUM C12-15 PARETH-15 SULFONATE.

Questionable / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sodium C12-15 Pareth-15 Sulfonate is an anionic surfactant primarily functioning as a cleansing and emulsifying agent, facilitating the removal of oil and dirt from the skin. While noted for its foaming capabilities and potential counter-irritancy, its overall skin compatibility includes conflicting reports regarding irritation.

Summary

Cleansing Agent Emulsifier Surfactant

Science

Mechanism of Action

This ingredient operates as a sulfonate-capped linear alkyl ethoxylate, acting as an anionic surfactant. Its primary function involves reducing the surface tension between water and lipid-based impurities, allowing water to effectively mix with and rinse away oil and dirt. Additionally, it exhibits emulsifying properties, aids in foam generation, and has been observed to mitigate skin irritation scores when combined with certain surfactant systems.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific safety review for Sodium C12-15 Pareth-15 Sulfonate. While some sources highlight its remarkable mildness and counter-irritancy, suggesting suitability for low-irritation systems, other data indicates it may be harsh, potentially causing dryness, redness, or itching. Therefore, individuals with sensitive skin are often advised to exercise caution or avoid products containing this ingredient, despite its classification for use in baby and hypoallergenic products. Related compounds, such as Sodium C12-15 Pareth Sulfate, have been deemed safe when appropriately formulated to be non-irritating.
