The role of n‐octacosane in promoting the growth of fibrous crystals of palmitic acid is studied. The study indicates that (i) adsorption is the probable interaction between the fatty acid and hydrocarbon molecules; (ii) The observed temperature dependence of occurrence of fibrous crystals warrants the adsorption to be a mixture of physisorption and chemisorption and (iii) it is the chemisorption component that is active at elevated temperatures and as a result it promotes the growth of fiber‐like crystals of the fatty acid.
