Zinc ricinoleate 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.
It’s most commonly used in natural underarm deodorants, but it works perfectly as an Air + Fabric Freshener, so why hide it? It’s also a better alternative to the toxic chemicals and masking agents used in conventional air fresheners.
None are recorded.
