    Product Description

    Arachidic acid is a long-chain saturated fatty acid that has been found in peanut butter and anaerobic fungi.1,2 It inhibits rabbit neutrophil aggregation induced by N-formyl-methionyl-leucyl-phenylalanine (fMLP; Item No. 21495) when used at a concentration of 5 μM.3 Formulations containing arachidic acid have been used as surfactants in the manufacture of soaps and cosmetics.

    WARNING This product is not for human or veterinary use.
