Zinc ricinoleate

Zinc ricinoleate is a low-melting, organic zinc salt of castor oil-derived ricinoleic acid. It is known to offer outstanding malodor absorbing properties by binding and trapping bad smells. The zinc in zinc ricinoleate selectively binds nitrogen and sulfur moieties of malodor molecules. The binding is further reinforced by the foldable ricinoleate chains which encapsulate bound malodor species. Industrially, it is also known to have gelling, emulsifying, waterproofing, vinyl stabilizing properties and can be used in plastics, rubber, polyurethane foams, paint, master batches, greases, agriculture, etc. Other uses include:
Anticaking agent
Gelling agent
Odor extinguisher
Opacifier
Substitute for dimethicone, clay, baking powder, zinc oxide, chloride, or sulphates
Mold release agent
Water proofer
