Zinc ricinoleate
Description
Zinc Ricinoleate – Effective odor neutralizer, active in natural deodorants
Zinc Ricinoleate is obtained by combining zinc with ricinoleic acid, the primary fatty acid in ricin oil. It is one of the most valued active ingredients for natural deodorant formulations due to its mode of action: it does not block perspiration nor does it possess antimicrobial properties, but rather traps and neutralizes the molecules responsible for unpleasant odor formed during the bacterial breakdown of sweat components.
This mechanism sets it apart from both classic antiperspirants (which block perspiration) and deodorants containing strong antibacterial agents, making it a staple ingredient in natural cosmetics and gentle formulations that respect the skin's natural microflora.
