Acid Oil

Acid oil is a by-product of vegetable oil refining, obtained by acidulating soapstock. It is a dark, viscous liquid with high free fatty acid content (typically 50–95%). It serves as a cost-effective feedstock for biodiesel production, soap and detergent manufacturing, animal feed, and industrial lubricants. Not suitable for human consumption due to its impurities and strong odour.
