SODIUM M-NITROBENZENESULFONATE.

Avoid CAS 127-68-4 / VISCOSITY CONTROLLING

Sodium M-Nitrobenzenesulfonate functions primarily as a mild oxidizing and anti-reduction agent, notably contributing to color stabilization in hair dye formulations and acting as a viscosity modifier in cosmetics. Its application in precision skincare is highly problematic due to significant safety concerns.

Summary

viscosity controlling agent

Science

Mechanism of Action

This compound acts as a mild oxidizing agent and prevents reduction reactions. In cosmetic applications, particularly hair dyes, it stabilizes reactive dyes by inhibiting their reduction, thereby preserving color integrity. It also serves as a viscosity-controlling agent, influencing the texture of formulations.

Stability

A 1% aqueous solution of Sodium M-Nitrobenzenesulfonate maintains a stable pH between 6.0 and 10.0. It demonstrates robust resistance to acidic, alkaline, and hard water conditions. Optimal storage is below +30°C to maintain stability, as the substance is hygroscopic and susceptible to light-induced alteration.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that there is insufficient data to support the safe use of Sodium M-Nitrobenzenesulfonate in cosmetic products. It is classified as a hazardous substance under OSHA 29 CFR 1910.1200. This ingredient is noted to be irritating to the eyes (H319, R36) and carries a significant risk of skin sensitization (H317, R43). Oral toxicity studies in rabbits show an LD50 greater than 2000 mg/kg, and skin irritation in rabbits was observed to be mild at a concentration of 500 mg/24h.

Our Assessment

Verdict

Avoid

With insufficient safety data from CIR, classification as a hazardous substance, and a high risk of skin sensitization, Sodium M-Nitrobenzenesulfonate is deemed unsuitable for precision skincare formulations.
