Description

Description: TECHNICAL FIELD [0001] The present invention relates to a hair shampoo,
Hair cosmetics used as hair rinses, hair conditioners, hair treatments, styling agents, hair packs, hair creams, hair sprays, hair waxes, hair restorers, hair restorers, etc. More specifically, a good feeling of use and a high refreshing feeling are imparted. The present invention relates to a hair cosmetic excellent in effect and durability. [0002] Hair shampoos, hair rinses, hair conditioners, hair treatments used for daily hair washing, or styling agents, hair packs, hair creams, hair sprays used for the purpose of styling and conditioning the condition of the scalp and hair It is well known that hair cosmetics such as hair waxes, hair restorers, and hair tonics may be blended with a refreshing agent for the purpose of giving a pleasant refreshing feeling during use and enhancing palatability. [0003] In this case, as a typical refreshing agent,
l-menthol and the like. However, when the amount of l-menthol is increased, the intensity of the refreshing sensation is improved, but the potency at the initial stage of application is too strong, and rather, a stimulus that is felt as "damage" is produced. In addition, skin disorders such as redness and rash may occur, and a simple increase in the amount is a concern from the viewpoint of safety. Furthermore, there is a disadvantage that the initial titer is strong but poor in sustainability. For this reason, various derivatives have been developed which are highly safe or provide a sustained refreshing sensation (JP-A-57-31680, JP-A-61-19404).
9, JP-A-8-225564, JP-A-9-2170
No. 83). For the purpose of enhancing the effect and improving the sustainability, various methods of using other components in combination with l-menthol have been invented (JP-A-1-149710, JP-A-06-329528, JP-A-06-329528). 10-130118
No. JP-A-2000-44924). [0006] However, various derivatives have improved irritation and persistence as compared with l-menthol, but are much more expensive than l-menthol and do not necessarily have a sufficient refreshing feeling. On the other hand, if the other component combination system does not have a sufficient improvement effect, or if the improvement effect is recognized, but it is used as a hair cosmetic, the combination component itself affects the feeling of use, so that it has high palatability. The product could not be provided. SUMMARY OF THE INVENTION [0007] The present invention has been made in view of the above circumstances, and provides a hair cosmetic composition having a good feeling of use, a high effect of providing a refreshing feeling, and an excellent sustainability thereof. The purpose is to do. Means for Solving the Problems and Embodiments of the Invention As a result of intensive studies to achieve the above object, the present inventor has found that (A) a refreshing agent and (B) a surfactant. By combining with a guanidine derivative or a salt thereof having a function, these components act synergistically to provide a hair cosmetic having a high refreshing sensation, excellent persistence and a good feeling of use. This led to the completion of the present invention. Hereinafter, the present invention will be described in more detail. The hair cosmetic of the present invention comprises (A) a refreshing agent,
