  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.

  本发明旨在提供一种含有γ-聚谷氨酸或其盐的头发治疗组合物、一种含有这种组合物的用于受损头发的护发化妆品及其用途。本发明的含有γ-聚谷氨酸或其盐的头发治疗组合物和用于受损头发的护发化妆品对头发的强度和摩擦力有很好的改善效果，因此它们可以为受损头发提供张力、弹性等，以防止或减轻头发分叉和断裂，并改善梳理和触感。此外，它们还能分别发挥γ-聚谷氨酸或其盐固有的保湿效果、在此基础上防止或改善头皮屑产生的效果、防止粘腻感或吱吱作响的效果，以及包括同时对头发产生适当残留倾向在内的各种功效。

  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.

  人们一直希望开发一种高防腐性和抗菌性的化妆品组合物，这种组合物既可用于乳液型化妆品，也可用于非乳液型化妆品。此外，还希望开发一种方法，以改善含有聚有机硅氧烷的ε-聚赖氨酸的化妆品组合物的防腐和/或抗菌效果，从而减少抗菌防腐剂的用量。本发明提供了一种化妆品组合物，该组合物包含一种或两种以上的含聚有机硅氧烷的ε-聚赖氨酸化合物的组合，这些ε-聚赖氨酸化合物是通过ε-聚赖氨酸与聚有机硅氧烷或其生理上可接受的盐以及多元醇反应而得到的。
