A composition suitable for hair care which has excellent hair conditioning effects and provides a pleasant sensory feeling during use. The composition contains basic amino acids and high alcohols, and is preferably free of non-polymeric alkyl quaternary ammonium salts, which are irritating and poorly biodegradable. The composition may also contain cationic polymers to enhance the conditioning effects. Anionic surface active agents, ampholytic surface active agents, or both, may also be incorporated into the hair care composition in order to impart hair cleansing properties.

Basic amino-acid derivatives or salts thereof may be obtained by reacting glycidyl ethers with basic amino acids or salts thereof, and are useful as surfactants.
When used as surfactants, the compounds of the invention show low irritability towards the skin or mucous membranes, and excellent conditioning effects and therefore can be used in a wide range of toiletry and detergent compositions.

A hair care composition with good conditioning effects and producing a desired feeling upon use comprises a higher alcohol in combination with a basic amino acid derivative formed by the reaction of a glycidyl ether or a 1,2-epoxyalkane ( both of which are epoxy compounds) with a basic amino acid. A cationic polymer or an anionic surface active agent and/or an ampholytic surface active agent may be used in addition to the above-mentioned components. In this way the use of alkyl quaternary ammonium salts, which are problematic in the irritation, the biodegradability and such like, may be avoided.
