Olein or oleic acid is a substance of natural origin, which is derived from vegetable and, more rarely, from animal fats. Technical olein is a mixture of fatty acids with an admixture of unsaponifiable substances and other organic compounds. It is obtained by compression or a non-pressing process.
Outwardly it is a transparent brownish viscous liquid, which is oxidized by access to oxygen.
GOST provides for the production of several grades of technical oleic acid - A, B and C, which differ in the total content of fatty acids, iodine number, pour point.
Acid Olein grade B-14 is produced according to GOST 7580-91.
In the same way they produce B-115 and analogues according to TU 9145-172-4731297-94.
Still some time ago let out technical olein of mark В on ТУ 9145-024-00336562-98 and on ТУ 9145-002-51043152-2005. But since they are of poor quality and, accordingly, cheap and not profitable brand B have been removed from production.
Still there are several analogues of foreign production qualifications are clean and higher, but the price is much higher than domestic brands.

Oleic acid B-14 is a technical fatty acid with the formula C18H34O2, produced under GOST 7580-91. Grade B-14 indicates specific requirements for the batch’s physicochemical indicators: mass fraction of fatty acids, moisture, acid number, saponification number, iodine number and pour point. When purchasing for an enterprise, it is important to check not only the name but also the quality certificate, packaging, production date and actual analysis results.
The acid number and iodine number help assess the stability of oleic acid B-14 and its compliance with the requirements of the production process. The acid number shows the amount of free fatty acids and affects dosage calculation when working with alkalis, emulsifiers or other components. The iodine number is related to the degree of unsaturation of the product, so it is monitored to assess batch repeatability.
When receiving oleic acid B-14, the integrity of canisters or drums, labelling, production date, quality certificate and the batch’s compliance with GOST 7580-91 are checked. Laboratory control looks at the mass fraction of fatty acids, moisture, unsaponifiable and unsaponified substances, acid number, saponification number, iodine number and pour point. Visually, the product should be a clear viscous liquid with a brownish tint at the set control temperature, without foreign inclusions, water or signs of separation.
Oleic acid B-14 is stored in tightly sealed factory containers, away from direct sunlight, heat sources, open flame and strong oxidisers. The product is classified as flammable, so the storage area must be organised with fire safety in mind and restricted personnel access. Canisters and drums are placed to prevent damage, leakage and batch contamination. For a wholesale buyer, the quality certificate, labelling, production date and observance of the guaranteed shelf life are important.
