What Is Oleic Acid 7075? Specifications, Production, and Uses
- Oleic Acid 7075 is a trade name for vegetable oleic acid with a minimum oleic acid (C18:1) content of 75%, obtained from splitting palm and palm kernel oils.[1]
- Oleic acid is a monounsaturated fatty acid (MUFA) with C18:1 chain, ω-9, a single double bond, and a melting point of about 16.3 °C.[2]
- Typical specifications include acid value 195–205 mg KOH/g, saponification value 197–207 mg KOH/g, and minimum iodine value 90 g I2/100 g.[1]
- In palm oil, oleic acid accounts for about 39% of total fatty acids, making it the largest monounsaturated fatty acid fraction.[3]
- Uses include oleochemical feedstock, soap, lubricants, cosmetics, and livestock nutrition.[1]
Oleic Acid 7075 is among the most widely traded fatty acid products from the palm industry. Its 75% oleate content makes it a versatile feedstock for oleochemicals and animal feed.

What Is Oleic Acid 7075?
Oleic Acid 7075 is a trade name for vegetable oleic acid with a minimum oleic acid content of 75%. The “75” in the product name refers to the minimum oleic acid content, while “70” denotes the C18 fatty acid product series. It is marketed under codes such as Wilfarin OA-7075 and ADWIL OA-7075.[1]
Oleic acid itself is a monounsaturated fatty acid with 18 carbon atoms and a single double bond at position 9 from the carboxyl end, written as C18:1 Δ-9 or C18:1 ω-9. It is liquid at room temperature with a melting point of about 16.3 °C.[2]
In palm oil, oleic acid accounts for about 39% of total fatty acids, followed by palmitic acid at about 44%, linoleic acid at about 11%, stearic acid at about 5%, and myristic acid at about 1%. This composition makes oleic acid the largest monounsaturated fatty acid in palm oil.[3]
Product Specifications
Oleic Acid 7075 specifications are set by manufacturers based on oleic acid content, purity, and physical properties. Two producers marketing similar products in Indonesia specify nearly identical limits.[1][4]

Chemistry and Properties of Oleic Acid
Oleic acid has a single cis double bond, which bends the molecular chain and prevents tight packing. This is why oleic acid is liquid at room temperature and has a much lower melting point than saturated stearic acid (C18:0).[2][6]
The single double bond makes oleic acid relatively stable but still prone to oxidation during long storage, especially when exposed to heat, light, and metals. Oleochemical fatty acid quality is typically assessed by acid value, saponification value, iodine value, and color.[2]
Nutritionally, monounsaturated fatty acids such as oleic acid are hypocholesterolemic: they lower total cholesterol and low-density lipoprotein (LDL) cholesterol while maintaining high-density lipoprotein (HDL) cholesterol.[3]
Production and Sources
Fatty acids such as Oleic Acid 7075 are obtained by fat splitting of triglycerides at high temperature and pressure, yielding free fatty acids and glycerol. The mixture is then purified by fractional distillation to separate fractions by chain length and degree of unsaturation.[1][5]
The main feedstocks are palm oil and palm kernel oil, so Indonesia’s vegetable fatty acid industry has abundant raw material supply. Wilfarin, Wilmar’s fatty acid brand, states that its fatty acids come from palm oil and palm kernel oil.[1]
Uses
Oleic Acid 7075 is used as an oleochemical feedstock, including for soap, surfactants, lubricants, and personal care products. The fatty acid is also a precursor for esters and derivatives used across industries.[1]
In animal feed, vegetable fatty acids including oleic acid serve as an energy source and feed supplement raw material. Wilmar markets a line of vegetable fatty acids for animal nutrition.[1]
The product is also used as a solvent and feedstock in pharmaceutical and cosmetic industries, where purity and color stability are primary considerations.
Summary
Oleic Acid 7075 is a vegetable oleic acid with a minimum C18:1 content of 75%, produced from splitting palm and palm kernel oils. Its specifications are marked by acid value 195–205 mg KOH/g, saponification value 197–207 mg KOH/g, and minimum iodine value 90 g I2/100 g. It is used as an oleochemical feedstock, in animal feed, and in various other industries.
