SODIUM C10-16 PARETH-2 SULFATE.

Questionable CAS 68585-34-2 / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING

SODIUM C10-16 PARETH-2 SULFATE is a versatile surfactant primarily functioning as a cleansing agent and foam booster in cosmetic formulations. It reduces liquid surface tension, enabling oil and water to combine and effectively remove impurities from skin and hair. This compound also enhances foam quality by increasing its volume, texture, and durability.

Summary

Cleansing Agent Surfactant - Foam Boosting

Science

Mechanism of Action

This ingredient functions as an anionic surfactant by lowering the surface tension of water, which allows oil and water-based substances to readily mix. This emulsifying property facilitates the solubilization and removal of fatty substances and particulate matter from the skin's surface during cleansing. Additionally, its foam-boosting capabilities contribute to a richer, more stable lather, enhancing the user experience.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The CIR Expert Panel found a closely related compound, Sodium C10-15 Pareth Sulfate, safe under specific usage and concentration limits. While general Sodium Sulfate assessments indicate safety in current practices when non-irritating, SODIUM C10-16 PARETH-2 SULFATE itself carries a likelihood of irritation, a risk amplified when combined with other potentially problematic ingredients, which can lead to inflammation or dryness. INCI Beauty assigns a 'medium penalty'. However, some sources consider it non-irritating, and SkinSAFE categorizes similar 'Sodium C10-16 Alketh Sulfate' as Teen SAFE, Baby SAFE, Eyelid SAFE, and Irritant Free.

Our Assessment

Verdict

Questionable

While effective as a cleansing and foam-boosting agent, its noted potential for skin irritation necessitates precise formulation and careful consideration, particularly for sensitive skin types, making its broad application questionable without further mitigation.
