OLEAMIDOPROPYL HYDROXYSULTAINE.

Valuable CAS 93941-94-7 / ANTISTATIC, CLEANSING, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING

Oleamidopropyl Hydroxysultaine is an amphoteric surfactant valued for its multi-functional properties in skincare. It effectively reduces surface tension, enabling thorough cleansing by facilitating the mixing of oil and water. Beyond its primary cleansing role, it also offers skin conditioning benefits and enhances foam quality in formulations.

Science

Mechanism of Action

As an amphoteric surfactant, Oleamidopropyl Hydroxysultaine carries both positive and negative charges within its molecular structure, resulting in an outwardly uncharged state. This amphoteric nature allows it to significantly lower the surface tension of liquids, thereby enabling oil and water to combine efficiently. On the skin, it functions to dislodge and suspend fat and soil particles, facilitating their removal during rinsing. It also contributes to maintaining the skin's healthy condition.

Stability

Oleamidopropyl Hydroxysultaine, as part of the hydroxysultaine class, exhibits robust stability across a broad pH range and performs consistently in both soft and hard water conditions.

Conflicts

  • Must not be used in cosmetic products where N-nitroso compounds have the potential to form. Its secondary amide structure can act as a precursor for N-nitrosation, requiring diligent adherence to current Good Manufacturing Practices (cGMPs) to minimize nitrosatable impurities.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Oleamidopropyl Hydroxysultaine, alongside other alkyl sultaines, is safe for cosmetic use under current practices and concentrations. It's important to note that this specific ingredient was not widely reported in current use at the time of the safety assessment. Should it be utilized in future formulations, its concentrations are expected to align with those of related alkylamidopropyl sultaines, which have been observed up to 11.5% in rinse-off products and 2.5% in leave-on applications. Manufacturers are mandated to follow cGMPs strictly to limit the formation of N-nitrosatable impurities.
