What is it?Zinc ricinoleate is a zinc salt of ricinoleic acid. The zinc source for the material is zinc oxide while ricinoleic acid is a purified fatty acid from castor seed oil, a vegetable oil obtained from the seeds of the Ricinus communis plant.
What does it do?In cosmetic applications, deodorizing means eliminating or preventing unpleasant odors. Zinc salts of ricinoleic acid are highly effective active deodorizing substances. The effectiveness of zinc ricinoleate is based on the elimination of odor; it binds unpleasant odorous substances in such a way that they are no longer perceivable.
What are the alternatives?Crown ether is an odor-absorbing molecule, but it is synthetic. Certain clays can absorb odor, as can baking soda under certain conditions. But zinc ricinoleate works better than these alternatives; in the damp underarm environment, it is activated and absorbs odor more effectively than clays and baking sodas, which don't perform well when wet.
What are the risks?Castor oil is obtained by the cold pressing of seeds of the Ricinus communis plant followed by clarification of the oil by heat. Some people ask whether or not castor oil and its derivatives contain the highly toxic compound ricin. Castor oil does not contain ricin because ricin is water soluble and does not dissolve in the oil obtained from the castor beans. Castor oil is approved by the Food and Drug Administration as a natural flavoring substance, as a direct food additive, and as a safe and effective stimulant laxative. Tom's of Maine recognizes that no two people are alike, and even with pure and natural ingredients, some individuals may develop an allergic reaction that is unique to them. As with any product, be sure to discontinue use if you experience discomfort or other indications that the product may not be appropriate for your individual body chemistry.
