Description

  The present invention relates to hair mist cosmetics such as hair mist.

  Hair is exposed to environmental stresses such as cosmetic treatment such as washing hair, the heat of a dryer, perm, decoloring, and dyeing, drying, and ultraviolet rays. As a result, the hair is in a damaged state, and the cuticle is peeled off, split hairs and cut hairs are generated, gloss, tension, stiffness, conspicuousness, and reduction in fingering are likely to occur. Therefore, hair cosmetics are required to have performances such as imparting luster to hair, improving finger passage and combing, and finishing well.

  Therefore, oily components such as silicone, polymers and cationic surfactants are blended in hair cosmetics. Silicone is widely used in cosmetics for hair because it is excellent in lubricity and, when applied to hair, it spreads thinly and uniformly and improves the fingering of the hair. Polymers are widely used in hair cosmetics because they protect hair and keep moisture, and cationic surfactants suppress the generation of static electricity and improve fingering.

  In recent years, spray-type mist cosmetics have been widely used because of their ease of use. However, a cationic surfactant having a high conditioning effect on hair has low water solubility, and when used in a mist cosmetic, it may cause clogging due to precipitation.

  For example, Patent Document 1 proposes a hair cosmetic that combines polymethacryloyloxyethyl phosphorylcholine or a derivative thereof, a cationic surfactant, and a water-soluble polymer. However, although this cosmetic can give the hair a sticky or moist feeling, it is not sufficient in terms of giving an appropriate volume feeling and good fingering to the hair.

  Patent Document 2 proposes a cosmetic for hair in which a copolymer having a specific glycerol (meth) acrylate monomer, a cationic surfactant, and an alkylene oxide derivative are combined. However, this cosmetic can impart gloss and wet combing properties to the hair, but it is not sufficient in terms of imparting an appropriate volume feeling and unity to the hair.

  Patent Document 3 proposes a hair mist cosmetic that combines a copolymer having a specific glycerol (meth) acrylate monomer, a specific cationic surfactant, and a specific nonionic surfactant. Yes. However, although this cosmetic can give the hair a natural luster and a moderate volume feeling and can suppress undulation, it is not sufficient in terms of imparting good fingering and clumping to the hair.

  Patent Document 4 proposes a hair cosmetic that combines a quaternary ammonium salt such as stearyltrimethylammonium chloride, a linear alcohol, a glycosyl trehalose, and a specific polyalkylene glycol derivative. However, although this cosmetic can give the hair firmness, firmness and luster, it is not sufficient in terms of giving the hair a volume feeling and good fingering.

The hair mist cosmetic of the present invention contains the following components A to D.
[Component A]
In the component A, the content ratios of the structural unit (l), the structural unit (m), and the structural unit (n) are 5 to 90 mol%, 5 to 90 mol%, and 3 to 80 mol%, respectively. The total content of the three structural units is set to 100 mol%.

  When the content ratio of the structural unit (l) is less than 5 mol%, the affinity for hair becomes insufficient, so that it is 5 mol% or more, but more preferably 10 mol% or more. Further, when the content ratio of the structural unit (l) exceeds 90 mol%, the viscosity is increased and the handling property is deteriorated. Therefore, the content is 90 mol% or less, and more preferably 50 mol% or less.

  When the content ratio of the structural unit (m) is less than 5 mol%, the gloss imparting effect on the hair becomes insufficient, so that it is 5 mol% or more, but more preferably 10 mol% or more. Further, if the content ratio of the structural unit (m) exceeds 90 mol%, the viscosity is increased and the handling property is deteriorated, so that it is 90 mol% or less.

  When the content ratio of the structural unit (n) is less than 3 mol%, the adsorptivity to the hair becomes insufficient, so that it is 3 mol% or more, but more preferably 10 mol% or more. In addition, when the content ratio of the structural unit (n) exceeds 80 mol%, the viscosity increases and the handling property is deteriorated. Therefore, the content is set to 80 mol% or less, and more preferably 60 mol% or less.

  Among these, from the viewpoint of the adsorptivity to hair and the gloss imparting effect, the content of the structural unit (l) is 10 to 40 mol% (particularly 20 mol%), and the content of the structural unit (m) is 25 to 50 mol. % (Particularly 40 mol%) and the content of the structural unit (n) is particularly preferably 25 to 50 mol% (particularly 40 mol%).

  The molecular weight of component A is in the range of 5,000 to 5,000,000 in terms of weight average molecular weight. When the molecular weight exceeds 5,000,000, the viscosity becomes extremely high, handling properties are deteriorated, and it becomes difficult to blend into cosmetics. From this viewpoint, the molecular weight of the component A is more preferably 2,000,000 or less. On the other hand, if the molecular weight of the component A is less than 5,000, the adsorptivity to hair is lowered. From this viewpoint, the molecular weight of the component A is more preferably 10,000 or more.

[B component]
Component B is a copolymer composed of a structural unit (x) that is 2-methacryloyloxyethyl phosphorylcholine and a structural unit (y) that is butyl methacrylate.

  The molar ratio of the structural units (x) and (y) in the copolymer is preferably x / y = 2/8 to 5/5. If it is less than x / y = 2/8, the water solubility decreases and causes precipitation, so x / y is set to 2/8 or more. From this viewpoint, it is more preferable that x / y is 2.5 / 7.5 or more. Further, if x / y exceeds 5/5, the adsorptivity to hair is insufficient, so x / y is set to 5/5 or less. From the viewpoint of the effect of imparting adsorptivity to hair and volume, x / y = 2.5 / 7.5 to 4/6 is more preferable, and 3/7 is particularly preferable.
