STEARAMIDE AMP.

Insufficient Data CAS 36284-86-3 / SURFACTANT - FOAM BOOSTING, VISCOSITY CONTROLLING

STEARAMIDE AMP is a multi-functional ingredient primarily employed in skincare and haircare for its surfactant properties. It significantly contributes to product formulation by enhancing aesthetic qualities like foam and pearlization, while also providing critical stability functions such as viscosity control and emulsion stabilization.

Summary

Viscosity Controlling Foam Boosting Emulsion Stabilising Pearlizing Agent Skin Conditioning

Science

Mechanism of Action

Acting as a surfactant, STEARAMIDE AMP interfaces at air-liquid and liquid-liquid boundaries within formulations. This enables its function as a foam synergist, improving lather volume, texture, and stability. It precisely adjusts product consistency as a viscosity-controlling agent and effectively stabilizes water-in-oil emulsions, characterized by an HLB value of 5-6. Beyond these technical roles, it also imparts a desirable pearlized effect and offers skin conditioning properties.

Stability

STEARAMIDE AMP exhibits chemical stability under standard conditions. While it is minimally soluble in water, it readily disperses in both aqueous and oil phases and demonstrates good solubility in organic solvents like ethanol and DMSO. Its lipophilic nature, confirmed by an HLB value of 5-6, makes it an effective stabilizer for water-in-oil emulsions. Typical use levels range from 2% to 10% for emulsification and around 4% for achieving a pearlizing effect.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

STEARAMIDE AMP has not been individually assessed for safety by the Cosmetic Ingredient Review (CIR) Expert Panel. While it is listed in the FDA Global Substance Registration System (GSRS), cosmetic ingredients in the U.S. do not require pre-market FDA approval, placing the responsibility for safety squarely on the manufacturer. It is notable that for related compounds, such as Stearamide DIBA-Stearate, available data were deemed insufficient to support their safety in cosmetic applications. The Scientific Committee on Consumer Safety (SCCS) has not issued a specific opinion on STEARAMIDE AMP.

Verdict

Insufficient Data

While offering valuable formulation benefits such as emulsion stabilization, viscosity control, and aesthetic enhancement, STEARAMIDE AMP lacks comprehensive safety assessments by regulatory bodies and direct clinical efficacy data for skin benefits, rendering it an ingredient requiring further investigation for precision skincare applications.
