DECYL MERCAPTOMETHYLIMIDAZOLE.

Insufficient Data CAS - / ANTIOXIDANT, ANTISTATIC, HAIR CONDITIONING

A specialized nitrogen-containing antioxidant primarily utilized to preserve the integrity of complex cosmetic matrices and shield the skin from oxidative degradation. It is characterized by its ability to neutralize reactive oxygen species and prevent the rancidity of lipid-based components in high-performance formulations.

Antioxidant Anti-rancidity Agent Surface Modifier

Science

This ingredient functions by interrupting the oxidation chain reaction, thereby inhibiting the degradation of both the product and the skin's surface lipids. Its molecular structure contains an amine group which allows it to potentially interact with reactive esters or amine groups on the skin and hair, providing a anchored protective antioxidant effect that resists immediate removal.

Transparency

Not commonly dusted

Due to the lack of established clinical benchmarks for efficacy, it is currently impossible to determine a threshold for 'dusting.' It is typically used as a functional stabilizer rather than a primary marketing active.

Stability

Research indicates that the antioxidant efficiency of this molecule is maximized within an acidic to slightly acidic environment, specifically between pH 4.0 and 5.0. Formulations outside this range may experience diminished performance of the amine-driven reaction mechanism.


Safety

CIR Status
Not reviewed
Sensitization risk Unknown

While listed in the EU CosIng database and assigned an FDA UNII, specific safety dossiers from the CIR or SCCS are not currently available. Users with highly reactive skin should approach new formulations containing this ingredient with standard patch testing.

Our Assessment

Insufficient Data

An intriguing, pH-dependent antioxidant that offers structural stabilization, though its specific benefits for human skin remain under-documented compared to industry standards.
