COCAMIDOPROPYL HYDROXYSULTAINE.

Valuable CAS 68139-30-0 / ANTISTATIC, CLEANSING, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, VISCOSITY CONTROLLING

Cocamidopropyl Hydroxysultaine is a gentle amphoteric surfactant utilized for its mild cleansing properties, foam-boosting capabilities, and ability to enhance formula viscosity. It also acts as a skin and hair conditioning agent, contributing to a soft, supple feel.

Antistatic Cleansing Foam Boosting Hair Conditioning Skin Conditioning Surfactant Viscosity Controlling Emulsifier Stabilizer

Science

Mechanism of Action

Operating as an amphoteric surfactant, Cocamidopropyl Hydroxysultaine stabilizes anionic surfactant micelles by reducing their charge density. This stabilization prevents micelle breakdown into irritating monomers, thereby safeguarding stratum corneum lipids and proteins. It functions as a mild cleansing agent, foam enhancer, and viscosity modifier. Furthermore, it imparts skin and hair conditioning by forming a thin film that limits moisture escape and serves as an antistatic agent, reducing potential irritation from other surfactants.

Key findings

  1. 01 Effectively boosts foam and enhances viscosity in rinse-off products such as shampoos, body washes, and liquid soaps when incorporated at concentrations ranging from 1% to 15%.
  2. 02 Used in concentrations of 1% to 10% in formulations specifically designed for sensitive skin, including baby washes and facial cleansers, highlighting its mild profile.
  3. 03 Demonstrated no skin irritation in rabbit studies, even at a high concentration of 41.5%.
  4. 04 Evaluated at 2.5% in a Human Repeat Insult Patch Test (HRIPT) and found not to be a dermal sensitizer.

Transparency

Dusting Analysis

Not commonly dusted

Cocamidopropyl Hydroxysultaine is a primary functional ingredient, incorporated in significant concentrations (typically 1-15%) for its active cleansing, foam-boosting, and conditioning properties, rather than being 'dusted' at sub-efficacious levels for marketing claims.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel deemed alkyl sultaines, including Cocamidopropyl Hydroxysultaine, safe for cosmetic use within current practice and concentrations. It is also approved by regulatory bodies like the FDA and EU Cosmetics Regulation. Generally considered non-comedogenic and not a carcinogen, it has low irritation potential. However, slight to moderate irritation was observed in a repeated induction patch test (HRIPT). It is not genotoxic or a reproductive toxin. Proper manufacturing purification is crucial to prevent contamination with dimethylaminopropylamine (DMAPA), a known irritant.
