COCO/SUNFLOWERAMIDOPROPYL BETAINE.

Valuable / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING, SURFACTANT - FOAM BOOSTING, VISCOSITY CONTROLLING

A plant-derived amphoteric surfactant, COCO/SUNFLOWERAMIDOPROPYL BETAINE facilitates effective cleansing by allowing oil and water to mix. It enhances foam quality and texture while also mitigating the irritant potential of other cleansing agents in formulations.

Summary

Surfactant/cleansing Foam boosting Viscosity controlling Hair conditioning Antistatic

Science

Mechanism of Action

As an amphoteric surfactant, COCO/SUNFLOWERAMIDOPROPYL BETAINE effectively reduces the surface tension of liquids, enabling the emulsification of oil and water for thorough cleansing. It significantly boosts foam volume, stability, and texture, contributing to an optimized user experience. Beyond its primary cleansing role, it functions as a viscosity controller, a hair conditioning agent providing anti-static benefits, and actively supports the maintenance of healthy skin by reducing the potential for irritation from co-surfactants.

Key findings

  1. 01 Reported concentrations in cosmetic products to the U.S. FDA in 2010 ranged from 0.005% to 11% for related amidopropyl betaines.
  2. 02 Typical concentrations in finished skincare and haircare products are observed between 1% and 10% for achieving functional benefits.
  3. 03 Human studies indicated weak irritation at concentrations up to 3% for Cocamidopropyl Betaine.

Stability

Optimal formulation stability and maximum skin compatibility are achieved within a pH range of 5.5-7.5, closely aligning with the skin's natural acidity. Its amphoteric structure allows it to exist in either cationic or anionic form, depending on the ambient pH.

Synergies

  • Enhances the gentleness of formulations by reducing the irritant potential of other surfactants.
  • Acts as an effective foam booster when combined with other surfactants.

Conflicts

  • Avoid use in products intended to remain on the skin for extended periods, as it may induce irritation.
  • Careful pH adjustment is critical when co-formulating with cationic ingredients to prevent incompatibility reactions.
  • The presence of manufacturing impurities, specifically amidoamine, must be minimized to mitigate sensitization risks.

Safety

Safety Profile

CIR Status
Safe with restrictions
Max tested
6%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that COCO/SUNFLOWERAMIDOPROPYL BETAINE and similar amidopropyl betaines are safe for cosmetic application, provided formulations are designed to be non-sensitizing, which may necessitate quantitative risk assessment. Instances of mild skin and eye irritation or sensitization have been reported, often attributed to residual impurities, such as amidoamine, from the manufacturing process rather than the pure ingredient itself. A maximum concentration of 6% is recommended for leave-on products, while up to 30% is permissible in rinse-off applications.
