SODIUM CAPRYLOAMPHOACETATE.

Valuable CAS - / CLEANSING, FOAMING, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING

Sodium Capryloamphoacetate is an intelligent amphoteric surfactant widely employed for its dual ability to cleanse and condition. It effectively purifies skin and hair by lifting impurities while simultaneously boosting foam and stabilizing formulations.

Science

Mechanism of Action

As an amphoteric surfactant, Sodium Capryloamphoacetate uniquely possesses both positive and negative charges, enabling it to interact with both oil and water. This dual affinity allows it to efficiently emulsify dirt, oil, and sebum, facilitating their removal from the skin and hair during rinsing. Beyond its primary cleansing action, it enhances foam generation and stability, conditions by aiding moisture retention, and offers pH buffering capabilities. A notable attribute is its capacity to mitigate the potential irritancy of other anionic surfactants within a formula.

Key findings

  1. 01 Research on related amphoteric surfactants, Sodium Lauroamphoacetate and Sodium Cocoamphoacetate, suggests effective cleansing and skin/hair integrity maintenance across 1-30% concentrations.
  2. 02 Specifically, Sodium Cocoamphoacetate at 10% was reported as non-irritating and non-sensitizing.
  3. 03 However, a separate study observed irritation at 1-2% concentrations of Sodium Lauroamphoacetate in specific dermal irritation assays.

Stability

Amphoteric surfactants, including related amphoacetates, exhibit both water and oil solubility. They maintain stability across a wide pH spectrum, encompassing strong acidic, strong alkaline, and neutral conditions. Commercial solutions of related amphoacetates often present alkaline pH values (e.g., 8.5-11) for microbiological stability.

Synergies

  • Reduces the irritancy potential of other anionic surfactants.
  • Aids in the deposition of cationic polymer ingredients in hair care formulations.

Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of fatty amphocarboxylates, which include Sodium Capryloamphoacetate, when used in cosmetics at present concentrations, provided the final formulation is non-sensitizing. The maximum safe concentration identified is 30%. The ingredient is listed in the FDA Global Substance Registration System (GSRS). While a related ingredient (Sodium Cocoamphoacetate) at 10% was non-irritating and non-sensitizing, another related compound (Sodium Lauroamphoacetate) showed irritation at 1-2% in specific dermal tests, highlighting the importance of proper formulation to mitigate potential risks.
