Cocamidopropyl hydroxysultaine

Cocamidopropyl hydroxysultaine suppliers and sourcing guide

Cocamidopropyl hydroxysultaine is an amphoteric surfactant made by reacting coconut fatty acids with dimethylaminopropylamine (DMAPA) to form an amidoamine, then reacting that with sodium 3-chloro-2-hydroxypropanesulfonate. It is used like cocamidopropyl betaine as a secondary surfactant that builds foam and viscosity in shampoos and body washes, and stays stable at a wider pH range. Brands buy it as a roughly 40 to 50% aqueous solution.

Forms and grades of cocamidopropyl hydroxysultaine

Suppliers sell different products under the same name. Specify the one you need.

  • Standard grade (about 40 to 50% active)

    Aqueous solution with sodium chloride by-product, in drums or totes.

  • Low-impurity grades

    Grades with tight limits on free amidoamine and DMAPA.

  • Natural-standard grades

    Coconut-derived grades approved for COSMOS or similar standards, preserved accordingly.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Active matter
Percent active surfactant by two-phase (Epton) titration or by solids minus salt; it sets how much product a formula needs and is the main lot-to-lot number to record.
Amidoamine and DMAPA
Free amidoamine and residual DMAPA by HPLC or GC, recorded for each lot.
Sodium chloride
Salt content from the reaction, which affects viscosity.
Residual chlorohydroxypropanesulfonate
Unreacted alkylating agent and related by-products, against the supplier's limit.
pH
pH of the product as supplied or of a stated dilution (often 10%), which affects viscosity building, preservative choice and stability of the finished product.
Microbiology and preservative
Total aerobic count, yeast and mold and specified organisms, plus the identity and level of any preservative the supplier adds to the aqueous solution.

Storage, lots and expiry

Storage and shelf life

Store closed at 5 to 40 °C, away from freezing; cold material can haze and is mixed after warming. Keep containers sealed to protect the preservative system. Shelf life follows the supplier's specification, with a retest of active matter, pH and micro for older stock.

Lots and expiry dates

Record active matter, salt and amidoamine/DMAPA results for each lot and adjust salt additions for viscosity. Rotate FIFO.

Regulatory status

Frequently asked questions

What forms of cocamidopropyl hydroxysultaine can brands buy?

Common forms include standard grade (about 40 to 50% active), low-impurity grades and natural-standard grades. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for cocamidopropyl hydroxysultaine include?

Expect active matter, amidoamine and DMAPA, sodium chloride, residual chlorohydroxypropanesulfonate, pH and microbiology and preservative, each with its method, specification and result for that lot.

How should cocamidopropyl hydroxysultaine be stored?

Store closed at 5 to 40 °C, away from freezing; cold material can haze and is mixed after warming. Keep containers sealed to protect the preservative system. Shelf life follows the supplier's specification, with a retest of active matter, pH and micro for older stock.

What is the regulatory status of cocamidopropyl hydroxysultaine?

Health Canada's Natural Health Products Ingredients Database lists cocamidopropyl hydroxysultaine (CAS 68139-30-0) with non-medicinal purposes including antistatic agent, cleansing surfactant and aqueous viscosity increasing agent, for topical use.
