Valuable / ABRASIVE, ANTISTATIC, CLEANSING, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, VISCOSITY CONTROLLING

Jojobamidopropyl Betaine is a gentle amphoteric surfactant derived from jojoba oil, designed for effective cleansing without compromising skin's integrity. It functions as a conditioning agent for both skin and hair, enhancing texture and feel.

Science

Mechanism of Action

This ingredient primarily functions by reducing surface tension, enabling oil and dirt to emulsify with water for easy rinsing. It provides conditioning benefits by adsorbing onto hair and skin surfaces. Furthermore, as a betaine derivative, it contributes to skin health by potentially modulating tight junction structure, thereby supporting the epidermal barrier, and may exhibit antimicrobial properties against certain fungi by influencing cell membrane synthesis. It also boosts foam and controls viscosity in cosmetic formulations.

Stability

Optimal pH for maximum skin compatibility in formulations typically ranges from 5.5 to 7.5. While acidic conditions can augment conditioning benefits, alkaline pH improves cleansing efficiency. It demonstrates robust temperature stability under normal manufacturing and storage conditions and is resistant to oxidation. Buffer systems are advised to maintain pH stability.

  • Strong oxidizing agents
  • Cationic ingredients (without careful pH adjustment)

Safety

Safety Profile

CIR Status
Safe with restrictions
Max tested
30%
Sensitization risk Low

The CIR Expert Panel concludes that alkyl betaines, including Jojobamidopropyl Betaine, are safe for use in cosmetics when formulated to be non-sensitizing. This non-sensitizing quality is achieved through quantitative risk assessment to manage impurities like 3,3-dimethylaminopropylamine (DMAPA) and fatty acid amidopropyl dimethylamine (amidoamine), which are known sensitizers. For similar ingredients, concentrations up to 6% in leave-on products and 30% in rinse-off products have been deemed safe. There is no specific FDA approval status or SCCS opinion for Jojobamidopropyl Betaine itself.
