What is Cocamidopropylamine Oxide CAS 68155-09-9?

Cocamidopropylamine Oxide, also called cocamidopropyl dimethylamine oxide, is a coconut-derived amine oxide surfactant with CAS 68155-09-9 and EC No. 268-938-5. It is commonly supplied as a pale yellow to colorless liquid for use in cleansing and detergent formulations.

What are the main applications of Cocamidopropylamine Oxide?

It is used in shampoo, facial cleanser, foaming cleansing gel, body wash, shower gel, makeup remover, and household or institutional liquid detergent systems. It is usually selected as a co-surfactant to support foam, mildness, and formulation compatibility.

What functions does Cocamidopropylamine Oxide provide in formulations?

It mainly provides foam boosting, foam stabilization, viscosity building, cleansing support, and conditioning. In suitable formulations it can also help reduce the harshness of primary anionic surfactants while maintaining foam quality.

What is the common supply form, active content, and pH of Cocamidopropylamine Oxide?

Commercial Cocamidopropylamine Oxide is usually a water-soluble aqueous liquid with active content around 30%, though some grades are in the 31-35% range. pH can vary by grade, with examples around 5.0-7.0 for 1% solution or 6.0-9.0 depending on the supplier specification, so the selected grade should be confirmed.

How is Cocamidopropylamine Oxide different from Lauramine Oxide or Cocamidopropyl Betaine?

All are mild amphoteric-type or amine-oxide surfactants, but Cocamidopropylamine Oxide has a cocamidopropyl dimethylamine oxide structure, while Lauramine Oxide is a lauryl dimethylamine oxide and Cocamidopropyl Betaine is a betaine. They can differ in foam, viscosity response, conditioning, and pH behavior, so they should be selected by application testing rather than used as automatic substitutes.
