Description

  The present invention relates to a hair cleansing composition.

  In addition to the basic function of removing dirt from the hair and scalp, a hair cleansing agent is required to be excellent in feeling such as unity, smoothness, and softness of the dried hair, and also excellent in durability. Also, in recent years, shaping hair into a desired shape with a permanent, a hair iron, and a hair styling agent has been routinely performed as a part of grooming and fashion. It is known that these often cause deterioration of the hair feel such as dryness, spreading of hair tips and stiffness due to chemical treatment and heat damage, and oiliness and excessive application feeling due to the styling agent.

  From such a background, Patent Document 1 discloses that a styling shampoo composition containing a specific detersive surfactant, a specific organic hair styling polymer and water has excellent styling performance without impairing the feel of hair. Is disclosed.

  On the other hand, hair cosmetics in which an acidic polymer having a specific structure is combined with an oxyalkylene polymer having a specific structure in an acid form are known, and Patent Document 2 discloses an oxyalkylene polymer having a specific structure. In addition, a (meth) acrylic acid-based polymer having a specific structure is combined in an acid state, and a water-based hair styling whose pH has been adjusted to 6 or less has sufficient self-selective adhesiveness after drying, so that it has setability and It is disclosed that it has re-styling properties and has little sticky feeling or stiffness.

  Further, in Patent Document 3, an oxyalkylene polymer having a specific structure is combined with a (meth) acrylic acid-based polymer having a specific structure different from that of Patent Document 2 in an acid form, and the pH is adjusted to 6 or less. Disclosed that the hair styling material, which has a moderate level of adhesive strength when dried, can create a hairstyle, and has sufficient setting and re-styling properties, so that it can be applied to brush blowing. Have been.

  By the way, the sleeping habit is a phenomenon in which the hair is shaped into an undesired shape by the external force applied to the hair from bedding or the like at bedtime, and is a troublesome phenomenon that many people feel in daily life. When correcting the bed habit, once the hair is wetted with water or a hairdressing agent, or humidified, the hydrogen bond existing inside the hair is cut once, and then dried with a drier or a hair iron to obtain a more preferable shape. An operation of reforming the hydrogen bond is required. This operation is generally complicated and takes a lot of trouble and time, so that a busy modern person is required to have a hair cleaning agent which makes it difficult for the person to fall asleep and has a good hair feeling until the next hair washing. I was

  However, although the styling shampoo composition of Patent Document 1 can impart and maintain the shaping property at the time of hair styling after shampooing, it does not suggest the effect of making the hair less likely to fall asleep, and has no effect. Was enough. In addition, there is room for improvement in that the hair becomes hard depending on the hair styling polymer used, giving an unpleasant feel.

  In addition, since the hair cosmetic composition of Patent Document 2 is applied at the time of hair styling and applied to create a style by self-selective adhesiveness, after application, when going to bed and applying external force to the hair, The combination of self-selective tackiness and external forces may result in a stronger habit.

  Further, the hair cosmetic composition disclosed in Patent Document 3 is a hair styling material applied at the time of hair styling and suitable for hair styling with brush blowing, and there is room for improvement in that the complexity of brush blowing remains. In addition, the document does not suggest at all about the difficulty of having a habit after using the hair cosmetics of Patent Document 3.

  Accordingly, the present invention provides a hair cleansing composition that is less likely to have a habit and imparts favorable smoothness and softness to the hair in terms of unity and feel.
