Expert Verdict
Zinc ricinoleate is a well-tolerated natural deodorant active that functions through dual mechanisms: physical absorption and entrapment of odor molecules via the long hydrocarbon chain and carboxylate group forming stable complexes with both hydrophobic and hydrophilic compounds, and selective antimicrobial activity against odor-causing bacteria without disrupting overall skin microbiome. Commonly used at concentrations exceeding 1% in roll-on formulations, frequently combined with hop extract and magnesium hydroxide. Excellent safety profile with minimal systemic absorption and very low sensitization potential.

Frequently Asked Questions
Is Zinc Ricinoleate safe in cosmetics?
Zinc ricinoleate is a well-tolerated natural deodorant active that functions through dual mechanisms: physical absorption and entrapment of odor molecules via the long hydrocarbon chain and carboxylate group forming stable complexes with both hydrophobic and hydrophilic compounds, and selective antimicrobial activity against odor-causing bacteria without disrupting overall skin microbiome. Commonly used at concentrations exceeding 1% in roll-on formulations, frequently combined with hop extract and magnesium hydroxide. Excellent safety profile with minimal systemic absorption and very low sensitization potential. The EU classifies Zinc Ricinoleate as "permitted". Safety rating: EXCELLENT. 4 toxicological study endpoint(s) are available in our database.
Is Zinc Ricinoleate allowed in the EU?
Zinc Ricinoleate EU regulatory status: permitted. This is based on EU Regulation 1223/2009 and its amendments.
What does Zinc Ricinoleate do in cosmetics?
Zinc Ricinoleate functions as: Deodorant; odor molecule absorption and trapping via porous zinc salt of ricinoleic acid. Does not inhibit sweating; acts by binding and neutralizing malodor compounds rather than antimicrobial action.. It is classified as a Active Ingredient in our database. CAS number: 13040-19-2.
What is the Margin of Safety for Zinc Ricinoleate?
adequate The Margin of Safety (MoS) is calculated using SCCS methodology. A MoS above 100 is generally considered safe. Use the MoS Calculator tool to calculate MoS for your specific formulation and product category.
What is the NOAEL for Zinc Ricinoleate?
The NOAEL (No Observed Adverse Effect Level) for Zinc Ricinoleate is 2.7 2105 based on a inhalation study via 1992 route in guinea pig. A total of 4 study endpoints are available. Source: REACH.
