Abstract
The present invention provides an easily-handled hair conditioning composition with a very low water content. The hair conditioning composition of the present invention is a composition comprising: (a) 10 to 90% by mass of one or more components selected from higher alcohols, higher fatty acids, and derivatives thereof, (b) 5 to 35% by mass of a cationic surfactant, and (c) a polyhydric alcohol and/or polyethylene glycol having a melting point of 155° C. or less, characterized in that the endothermic peak of a gel which is formed from (a) and (b) in the composition is 50° C. or more as measured by a differential scanning calorimeter (DSC) and that the water content is 10% by mass or less.
