Description

  The present invention can provide sufficient smoothness, moistness, sufficient smoothness after drying, and good combing after rinsing off after applying to hair and repairing damage such as broken hairs and split ends The present invention relates to a hair cosmetic that is highly effective.

  Hair cleaners such as shampoos, which are mainly composed of an anionic surfactant, remove not only the dirt on the hair but also the oil that protects the hair surface during hair washing. It can be lost and the combing can get worse. In order to improve this, hair cosmetics such as rinses, conditioners and treatments are used. These hair cosmetics contain a quaternary ammonium salt as a main component in order to improve the feel of the hair, and in order to further enhance the effect, an aliphatic alcohol such as cetanol or an oil agent is blended. The dosage form emulsified in a gel form is mainly used. However, these can never be said to give sufficient smoothness and moistness to the hair, and can also be sufficiently satisfied in terms of the effect of repairing damage such as broken hairs and split ends caused by external factors such as brushing. There wasn't. It is also known that the reduction of irritation to hair, scalp or skin is not sufficient.

In recent years, it has been found that a specific amidoamine compound or an acid salt thereof can impart smoothness and flexibility to hair, and a hair cosmetic containing the amidoamine compound or an acid salt thereof has been proposed (Patent Document 1, Patent). Literature 2, Patent Literature 3, Patent Literature 4, Patent Literature 5, Patent Literature 6, Patent Literature 7). It is also known that the amidoamine compound or a salt thereof can provide a hair cosmetic that is highly safe and has a mild action on the skin or the like (Patent Document 8, Non-Patent Document 1). As such a specific amidoamine, dimethylaminopropylamide stearate is widely known, but there is a problem in gel formation when an aliphatic alcohol or an oil is blended, and the smoothness and moist feeling given to the hair. Was never satisfactory.
