Does CAS 112-80-1 alone define the commercial grade of Oleic Acid?

No. CAS 112-80-1 confirms the oleic-acid identity, but commercial material can differ in vegetable source, oleic-acid content, total fatty-acid profile, color, titer and refining. Confirm the source, grade and fatty-acid limits before ordering.

What is Oleic Acid used for?

It is used in soaps and oleochemical derivatives, lubricants and metalworking fluids, surfactants, emulsifiers, textile and leather auxiliaries, cosmetics, and pharmaceutical or personal-care formulations. The preferred grade depends on the downstream reaction or formulation.

Which batch specifications should be agreed for Oleic Acid?

Agree the assay or fatty-acid composition by the stated GC method, acid value, iodine value, saponification value where used, moisture, unsaponifiable matter, titer, color and odor. Different vegetable sources and refining steps can move these values.

What should be confirmed for drum, IBC or bulk Oleic Acid delivery?

Confirm liquid temperature, titer or low-temperature flow behavior, approved drum, IBC, flexitank or tank format, net quantity, previous cargo, and heating capability if the material must remain liquid. Also agree on document and quality-control release requirements.

How does Oleic Acid differ from Stearic Acid or Elaidic Acid?

Oleic Acid, CAS 112-80-1, is cis-9-octadecenoic acid with one double bond and is normally a low-melting liquid to soft solid. Stearic acid is the saturated C18 analogue, while elaidic acid is the trans isomer of oleic acid and melts much higher. Use the CAS and source-specific fatty-acid profile to avoid substitution.
