Improved particulate benefit agent deposition onto hair is achieved with a corn position comprising: (i) a linear, cationic conditioning surfactant; (ii) a linear fatty material; (iii) a particulate benefit agent (iv) a branched cationic co-surfactant, selected from structure 1, wherein the molar ratio of branched cationic co-surfactant (iv) to linear cationic surfactant (i) is in the range of from 1:20 to 1:1.
