Sodium coco-sulfate

Sodium coco-sulfate suppliers and sourcing guide

Sodium coco-sulfate is an anionic surfactant made by sulfating the full range of fatty alcohols derived from coconut oil and neutralizing with sodium hydroxide. It is chemically close to sodium lauryl sulfate but keeps a broader chain distribution, including some longer chains. It is used in shampoo bars, bath bombs, powders and washes. Brands buy it mostly as a high-active (about 90% or more) powder or needles, and less often as a solution.

Forms and grades of sodium coco-sulfate

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

  • Needles or noodles (about 90% active)

    Low-dust solid form, the usual choice for shampoo bars and solid products.

  • Powder

    Finer form that dissolves faster but generates more dust.

  • Liquid

    Aqueous solution offered by a few suppliers for liquid washes.

  • 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.
Unsulfated alcohol
Free fatty alcohol content against the supplier's limit.
Sodium sulfate and sodium chloride
Inorganic salt content by titration.
Alkyl chain distribution
Chain lengths by GC, which differ from SLS and change foam and solubility.
pH
pH of a 1% or 10% solution.
Heavy metals
Lead, arsenic and other elements by ICP-MS or ICP-OES against the supplier's specification or the applicable USP, FCC or cosmetic-grade limit.

Storage, lots and expiry

Storage and shelf life

Store sealed in a cool, dry place; powder and needles absorb moisture and cake, and the dust irritates airways during handling. Shelf life follows the supplier's specification, with a retest of active matter and appearance for older stock.

Lots and expiry dates

Record form, active matter and chain distribution for each lot. Use dust controls when weighing and rotate FIFO.

Frequently asked questions

What forms of sodium coco-sulfate can brands buy?

Common forms include needles or noodles (about 90% active), powder, liquid and natural-standard grades. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for sodium coco-sulfate include?

Expect active matter, unsulfated alcohol, sodium sulfate and sodium chloride, alkyl chain distribution, pH and heavy metals, each with its method, specification and result for that lot.

How should sodium coco-sulfate be stored?

Store sealed in a cool, dry place; powder and needles absorb moisture and cake, and the dust irritates airways during handling. Shelf life follows the supplier's specification, with a retest of active matter and appearance for older stock.

What is the regulatory status of sodium coco-sulfate?

Health Canada's Natural Health Products Ingredients Database lists sodium coco-sulfate (CAS 97375-27-4) with non-medicinal purposes of emulsifying agent and cleansing surfactant. The same database entry restricts it to topical use only, citing CosIng.
