Description

  The present invention relates to a hair treatment agent.

  As a hair treatment agent, one containing amino-modified silicone is known (see JP 2010-215541 A). The hair treatment agent described in this publication is configured as a multi-drug type, and an amino-modified silicone is blended with the first agent. Such a multi-component hair treatment agent is used by applying the first agent to the hair and further applying the second agent again, followed by washing with water.

  However, when amino-modified silicone is blended in the hair treatment agent, there is a bad feeling of oily fingers when washed with water after application, and the feeling of running is poor. In particular, when a relatively large amount of amino-modified silicone is blended in the hair treatment agent, such as for treatment, the poor feeling of flowing becomes more prominent.

JP 2010-215541 A

  This invention is made | formed in view of an above-described situation, and it aims at providing the hair treatment agent which can improve the badness of an oily finger at the time of the water washing after application | coating, and can improve a feeling of flowing.

  The invention made in order to solve the said subject is a hair treatment agent with which amino modified silicone, a cationic surfactant, a higher alcohol, and cationized cellulose are mix | blended, and the compounding quantity of the said amino modified silicone is 3 mass% or more.

  The hair treatment agent preferably has a creamy form and is used for washing away after application.

  Since the hair treatment agent contains cationized cellulose in addition to amino-modified silicone, the reason for this is not clear. Can be improved.

  As a compounding quantity of the said cationized cellulose, it is 2 mass parts or more and 40 mass parts or less with respect to 100 mass parts of said amino modified silicone, for example.

  ADVANTAGE OF THE INVENTION According to this invention, the hair treatment agent which can suppress deterioration of the feeling of flowing, such as a fingering at the time of the water washing after application | coating, is provided.

  The hair treatment agent of the present invention contains amino-modified silicone, cationic surfactant, higher alcohol and cationized cellulose. The hair treatment agent may contain nonionic surfactants, silicones other than amino-modified silicones, polyhydric alcohols, and lower alcohols, and may contain other optional components as long as the effects of the present invention are not impaired. Also good. Hereinafter, these components will be described in detail.

[Amino-modified silicone]
The amino-modified silicone is a silicone having an amino group directly or via a substituent on the silicone skeleton. Examples of the amino-modified silicone include compounds represented by general formula (1) and general formula (2).

  In said general formula (1), x and y show the integer of 1-5, and m and n show the integer depending on molecular weight.

  In the general formula (2), v and w are integers of 1 to 5, and p and q are integers depending on the molecular weight.

  Examples of the compound represented by the general formula (1) include an aminoethylaminopropylmethylsiloxane / dimethylsiloxane copolymer ((aminoethylaminopropylmethicone / dimethicone) copolymer) in which x = 3 and y = 2. Examples of the compound represented by the general formula (2) include aminoethylaminopropylsiloxane / dimethylsiloxane copolymer (amodimethicone) in which v = 3 and w = 2.

Aminoglycol-modified silicone, acrylic / amino-modified silicone, aminophenyl-modified silicone, and the like. These amino-modified silicones may be used alone or in combination of two or more.

  The lower limit of the amount of amino-modified silicone in the hair treatment agent is 3% by mass. Even if it is this compounding quantity, since a cationized cellulose is mix | blended, the feeling of flowing at the time of washing the said hair treatment agent with water improves. On the other hand, the upper limit of the amount of amino-modified silicone is not particularly limited, but is preferably 8% by mass, more preferably 7% by mass, and even more preferably 6% by mass. Thus, by making the compounding quantity of amino-modified silicone into the said range, while being able to provide sufficient conditioning effect to the hair after a process, generation | occurrence | production of the hardness and stickiness of hair can be reduced.

  The amino content of the amino-modified silicone (the nitrogen content in the amino-modified silicone) is preferably 0.5% by mass or more and 3.0% by mass or less, and more preferably 0.7% by mass or more and 2.2% by mass or less. Thus, by making the amino content of the amino-modified silicone within the above range, the above-mentioned conditioning effect and the effect of improving the flow feeling can be suitably achieved.
