Description

  The present invention relates to a hair cosmetic.

  Conventionally, hair cosmetics such as shampoos, rinses, conditioners, treatments, hair dyes, and mousses have been required to impart smoothness, smoothness and moisturizing feeling when touched by hand. .

  For example, as a technique for imparting flexibility and smoothness to hair, Patent Document 1 discloses a specific organopolysiloxane having an amino-modified organopolysiloxane chain and a polyoxyalkylene chain, and a specific cationic surfactant. Hair cosmetics formulated by combining these are disclosed. Furthermore, as a technique for imparting excellent smoothness to the hair ends, Patent Document 2 discloses a hair cosmetic containing a combination of a cationic surfactant and an amino-modified silicone. As an optional component, there is a description that a lotus extract can be blended as a physiologically active component.

JP 2002-249418 A JP 2005-89372 A

  However, in the techniques described in Patent Documents 1 and 2, the combination of a cationic surfactant and an oil agent such as an organopolysiloxane can impart flexibility and smoothness to the hair, but the remaining organo In some cases, the oily agent such as polysiloxane is difficult to obtain a sufficient dry feeling on the hair after drying. In addition, the oil remaining on the hair may make it difficult for each hair to separate, leaving a feeling of feeling heavy. Therefore, there is still room for improvement in terms of touch when the hair is touched by hand.

  The present inventor uses a hair cosmetic that is a combination of a specific amino-modified silicone and a lotus extract, so that a smooth feeling can be obtained even if an oil agent is included, and each hair can be easily separated. Thus, it has been found that the hair after combing with a hand comb or brush can be easily aligned, and the hair feels cool and comfortable when touched by hand.

That is, the present invention includes the following components (A) to (C):
(A) Tertiary amine compound or salt thereof (B) Amino-modified silicone represented by general formula (1) or (4)

Here, the “chilly feeling” obtained by the hair cosmetic composition of the present invention is one of the tactile sensations of the hair such as smoothness, smoothness and moistness, and is a tactile sensation in contrast to the warm feeling. Conventionally, it has been difficult to objectively evaluate such tactile sensation required for hair cosmetics. However, as a result of intensive studies, the present inventors have found that there is a correlation between the temperature change of the palm when touching the hair bundle and the cool feeling. Therefore, after using the hair cosmetic composition of the present invention, the measurement site (sensor) of KEF-F7 finger robot thermolab (manufactured by Kato Tech Co., Ltd.) is brought into contact with the hair bundle, and the amount of heat transfer q _max (mW / By measuring cm ² ), the cool feeling can be evaluated. Although the cause of this is not clear, it is presumed that when the hair is arranged and aligned, the amount of air between the hairs decreases, so that the amount of heat transfer increases, resulting in a cool feel.

The amount of heat transfer can be measured as follows.
H. Tanamachi, Temperature as a moisture cue in haptics on hair, Int. J. et al. Cos. Sci. In accordance with the method described in, in-press, a temperature sensor unit covered with silicone rubber of KEF-F7 finger robot thermolab (manufactured by Kato Tech Co., Ltd.) on a hair bundle of about 20 g in an environment of 20 ° C. and 40% RH. It was warmed to 36 ° C., which was the same as the body temperature, and contacted. At the time of contact, the heat of the temperature sensor moves to the hair bundle, and the heat transfer rate q is measured from the change in the heat signal at that time, and the peak value q _max is calculated.
