Polyricinoleic Acid

Polyricinoleic Acid is the polymer of Ricinoleic Acid

Polyricinoleic acid (also known as ricinoleic acid homopolymer), abbreviated to PRA, is a biodegradable polyester. PRA is widely used in lubricants, hydraulic oils, greases, plastics, inks, foodstuffs, cosmetics and surfactants, amongst other applications. These ester compounds are increasingly being used as viscosity modifiers in chocolate and low-fat spreads, as emulsifiers in margarine, as base oils for cutting oils in metalworking, and as pigment dispersants in paints, inks and cosmetics [1].
