Description:

Cocamidopropylamine Oxide is a mild amphoteric surfactant and tertiary amine oxide valued for its dual role as a cleansing and conditioning agent. It enhances foam, improves formula mildness, and helps build viscosity, making it an excellent co-surfactant in personal care formulations. It is typically supplied as a pale yellow to colorless liquid soluble in water.

Uses:

This ingredient is a common component in cosmetics and personal care products, found in cleansing gels, shampoos, and makeup removers.

· Skin Care: Acts as a surfactant that reduces surface tension for a more stable product. It mixes well with oil and water for effective cleansing.

· Hair Care: Cleans hair shafts, promotes product spreadability, and provides conditioning properties that leave hair shiny and smooth.

· Cosmetic Products: Acts as a conditioning agent that adds hydration and prevents products from drying out.

Origin:

Cocamidopropylamine Oxide is semi-synthetic, produced from coconut oil. The oil is reacted with dimethylaminopropylamine and then with hydrogen peroxide to form the final tertiary amine oxide compound.

What does COCAMIDOPROPYLAMINE OXIDE do in a formulation?

Its primary functions are:

  • Cleansing
  • Foam Boosting
  • Hair Conditioning
  • Skin Conditioning
  • Surfactant

Safety Profile:

· General Assessment: A safety review concluded it is safe as used in rinse-off products. It is considered to have low toxicity.

· Use Concentration: Recommended safe for use at concentrations between 0.07% and 4.0% in cosmetic formulations. Use higher than this range can cause allergy and irritation.

· Irritation Potential: A 5% solution was not a primary dermal irritant in tests, but the concentrated raw material (81.5%) caused moderate skin and severe eye irritation in animal studies. It was not a sensitizer in clinical testing.

· Important Note: A patch test is recommended prior to full usage, especially for those with highly sensitive skin.
