zinc diricinoleate

Zinc diricinoleate is the zinc salt of ricinoleic acid, a major fatty acid found in castor oil.  It is used in many deodorants as an odor-adsorbing agent. 

Fine white powder; faint fatty acid odor. Mp 92–95C, d 1.10 (25/25C). Combustible.

Fungicide, emulsifier, greases, lubricants, waterproofing, lubricating-oil additive, stabilizer in vinyl compounds.

The metal ion zinc in  zinc ricinoleate reacts with the fatty acid esters in the skin and forms a protective layer that prevents the skin from becoming dry or irritated.It also inhibits bacterial growth by preventing the synthesis of proteins needed for cell division.

Zinc Ricinoleate is a zinc salt of Ricinoleic Acid, a dilutable malodor absorber used in home and personal care products. In addition, it is a common ingredient in household products, sanitary products, air fresheners, car care, pet care products, and cat litter. It is also being implemented in various industrial and ecological applications, including landfill, garbage, paper, and sewage industries. It removes unpleasant-smelling substances such as cigarette smoke, isovaleric acid, mercaptans, hydrogen sulfide, ammonia, and amines from the ambient air or prevents their emission into the ambient environment. Once in the water phase, the zinc atom is accessible and reactive to functional groups from unpleasant-smelling substances. Zinc Ricinoleate is a concentrate that is directly dilutable in water, non-toxic, and readily biodegradable. The simplicity of its formulation via dilution creates numerous low-cost, low- complexity manufacturing options.
