Sodium cocoamphoacetate

Sodium cocoamphoacetate suppliers and sourcing guide

Sodium cocoamphoacetate is an amphoteric surfactant made by condensing coconut fatty acids with aminoethylethanolamine to form an imidazoline, which is then reacted with sodium monochloroacetate. It is used in baby washes, facial cleansers and sulfate-free shampoos, often with glucosides or anionic surfactants. Brands buy it as a roughly 30 to 40% aqueous solution.

Forms and grades of sodium cocoamphoacetate

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

  • Standard grade (about 30 to 40% active)

    Aqueous solution containing sodium chloride from the reaction.

  • Salt-reduced grades

    Lower-salt versions for clear formulas or where viscosity is built by other means.

  • Disodium cocoamphodiacetate

    A related di-substituted amphoteric with its own INCI name, made with more monochloroacetate.

  • Natural-standard grades

    Coconut-derived grades approved for COSMOS or similar standards.

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.
Sodium chloride and monochloroacetate
Salt content, plus residual monochloroacetic and dichloroacetic acid by HPLC or ion chromatography.
Free amine (aminoethylethanolamine)
Residual amine starting material 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 residual monochloroacetate for each lot. Rotate FIFO.

Regulatory status

Facts from regulators and standards bodies, each linked to its source.

This is general information, not regulatory advice. Status differs by country and by how the ingredient is used, so check the rules for your product and market.

Frequently asked questions

What forms of sodium cocoamphoacetate can brands buy?

Common forms include standard grade (about 30 to 40% active), salt-reduced grades, disodium cocoamphodiacetate and natural-standard grades. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for sodium cocoamphoacetate include?

Expect active matter, sodium chloride and monochloroacetate, free amine (aminoethylethanolamine), pH and microbiology and preservative, each with its method, specification and result for that lot.

How should sodium cocoamphoacetate 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 sodium cocoamphoacetate?

Health Canada's Natural Health Products Ingredients Database lists sodium cocoamphoacetate (CAS 90387-76-1) with the non-medicinal purpose cleansing surfactant. The same database entry restricts it to topical use, up to 6% in rinse-off products only, citing CIR.
