Full Description

Sodium oleate (CAS 143-19-1) is the sodium salt of oleic acid, an anionic fatty-acid soap and surfactant. HSDB documents its use in ore flotation, textile waterproofing, metal polishes, and polymer curing, and as an emulsifier for oil/water systems and in the emulsion polymerization of butadiene.

Frequently Asked Questions

Is sodium oleate a soap?

Yes. Sodium oleate (CAS 143-19-1) is the sodium salt of oleic acid, which makes it a fatty-acid soap and anionic surfactant. This is the same chemistry behind traditional soaps. RawSource supplies it for industrial use rather than as a finished consumer product.

What is another name for sodium oleate?

It is also called oleic acid sodium salt or sodium cis-9-octadecenoate, CAS 143-19-1. The HS classification is 2916.15 (salts and esters of oleic, linoleic or linolenic acids). Confirm the exact INCI or trade name against the CoA for your grade.

What is sodium oleate used for?

HSDB documents its use as a collector in ore flotation, an emulsifier for oil/water systems, and an emulsifier in the emulsion polymerization of butadiene. It is also used in textile waterproofing, metal polishes, and polymer curing. RawSource supplies it for these industrial surfactant and processing applications.

Is sodium oleate available as a powder?

Grade and physical form (powder versus solution) vary by supplier and intended application. Specify your required form, purity, and packaging when requesting a quote and we will confirm what is available against a CoA. Do not assume a form across grades.

What bulk packaging is sodium oleate available in?

RawSource ships industrial chemicals in drums, totes, and IBCs to manufacturers, with packaging matched to grade and order volume. Request a quote with your target quantity for delivered pricing, CoA, and SDS.
