cis-4-Decenoic, trans-4-decenoic, and Rac.-3-hydroxydecanoic acids and their sodium salts had antiseptic effect on bacteria, yeast and mold Especially, cis-4-decenoic and trans-4-decenoic acids showed a remarkable effect than Rac.-3-hydroxydecanoic acid, sodium cis-4-decenoate, sodium trans-4-decenoate and sodium Rac.-3-hydroxydecanoate. The antiseptic property of these free fatty acids and their corresponding sodium salts were greater in the medium of low pH. For example, the minimum inhibitory concentration of cis-4-decenoic acid was 1/5000 for Bacillus subtilis, Bacillus megateriuna, Mucor praini, Rhizopus chinensis, Penicillium roqueforti, Aspergillus niger, Candida lipolytica and Saccharomyces cerevisiae on a glucose-peptone medium in pH 4.
