Zinc Ricinoleate (CAS 13040-19-2) is the zinc salt of ricinoleic acid derived from castor oil, supplied as granules or pellets that chemically bind amine, mercaptan and sulfur-containing odor molecules in deodorants, industrial detergents and air fresheners. It is widely utilized in personal care formulations to permanently trap unpleasant odors caused by amines, mercaptans, and sulfur-containing compounds.
This compound operates by chemically binding nucleophilic odor molecules, preventing them from being released back into the atmosphere, making it ideal for long-lasting deodorants. It is compatible with most surfactant systems and is available in granules or pellets for easy incorporation into liquids and solids.
Beyond cosmetics, it serves as a critical additive in industrial cleaning products, ensuring effective odor neutralization in textiles, surfaces, and waste treatment applications. Manufacturers value its biodegradability and non-interfering nature with the skin’s natural flora.

Zinc Ricinoleate
Applications
- Deodorant Formulations: Acts as the primary active ingredient in stick, roll-on, and cream deodorants to neutralize body odor without inhibiting natural transpiration.
- Industrial Detergents: Incorporated into laundry detergents and hard surface cleaners to remove stubborn smells like smoke, sweat, and pet odors from textiles and floors.
- Pet Care Products: Used in animal shampoos and stain removers to chemically bind and eliminate strong biological odors.
- Air Fresheners: Deployed in solid and gel air fresheners to absorb household malodors rather than simply covering them with perfume.
- Waste Treatment: Applied in specialized treatments for landfills and sewage plants to control hydrogen sulfide and amine emissions.
Safety & Risks
Zinc Ricinoleate is generally considered safe for industrial handling but is classified as an Environmentally Hazardous Substance (toxic to aquatic life with long-lasting effects). Personnel should wear safety goggles and protective gloves to prevent potential eye irritation. Ensure adequate ventilation to avoid inhaling dust during processing.
