The present invention intends to provide a composition for hair treatment containing γ-polyglutamic acid or a salt thereof, a hair cosmetic for damaged hair containing such a composition, and their uses. The composition for hair treatment containing γ-polyglutamic acid or a salt thereof and the hair cosmetic for damaged hair of the present invention have excellent improvement effects on the strength and frictional force of hair, so that they can provide tension, elasticity, or the like to damage hair to prevent or alleviate split hair and broken hair as well as improvements in combing and touch. Furthermore, they also exert effects of moisture retention inherent to γ-polyglutamic acid or a salt thereof, preventing or improving effects on the generation of dandruff on the basis of such effects, preventing effects on the feeling of stickiness or creak, and various effectiveness including appropriate residual tendency to hair in a simultaneous manner, respectively.
It has been desired to develop a highly preservative and antibacterial cosmetic composition that can easily be applied to both emulsion and non-emulsion type cosmetics. It has also been desired to develop a method of improving a preservative and/or antibacterial effect(s) of a cosmetic composition comprising polyorganosiloxane-containing epsilon-polylysine and thereby reducing the amount of antibacterial preservative agent to be used. There is provided a cosmetic composition comprising one or a combination of two or more of polyorganosiloxane-containing epsilon-polylysine compounds obtained by reacting epsilon-polylysine with polyorganosiloxane or a physiologically acceptable salt thereof, and polyhydric alcohol.
