Full Description

Oleic acid (CAS 112-80-1; C18H34O2) is a monounsaturated C18 fatty acid supplied as an industrial monocarboxylic fatty acid. Established uses include the manufacture of soaps, oleate esters and surfactants, plasticizers and lubricant additives, ore flotation, textile and metalworking processing, and use as a defoaming agent in wet-process phosphoric acid.

Frequently Asked Questions

What is oleic acid used for?

Oleic acid (CAS 112-80-1; C18H34O2) is an industrial monounsaturated C18 fatty acid used in soap, oleate-ester and surfactant manufacture, oleate plasticizers and lubricant additives, ore flotation, textile and metalworking processing, and as a defoaming agent in wet-process phosphoric acid production.

What is another name for oleic acid?

Its systematic name is (9Z)-octadec-9-enoic acid, a C18:1 monounsaturated fatty acid carrying CAS 112-80-1. It is supplied industrially as a monocarboxylic fatty acid.

Is oleic acid the same as olive oil?

No. Olive oil is a triglyceride mixture in which oleic acid is the predominant fatty acid; oleic acid is the isolated free fatty acid (CAS 112-80-1). RawSource supplies the industrial free fatty acid, not olive oil.

What is the HS code for oleic acid?

Oleic acid is classified under HS heading 3823.12 (industrial monocarboxylic fatty acids). Verify the full destination tariff line with your broker.

What is the cost of bulk oleic acid?

Bulk oleic acid pricing tracks volume, grade, packaging (drum/IBC/bulk), and freight. Send your quantity and delivery point for a current landed quote; we do not quote fixed list prices on a volatile fatty-acid feedstock.
