Description

  The present invention relates to a hair cosmetic, and more specifically, has a texture that stretches and is familiar to the hair, gives the hair a moist feeling and a smooth finish that is not sticky, and maintains a good set. The present invention relates to a hair cosmetic material having a property.

  Conventionally, various film-forming polymers have been used in hair cosmetics for the purpose of setting hair. However, hair cosmetics that use these film-forming polymers alone stretch to the hair and feel bad, feel sticky when dry, feel stiff after drying, or flake and peel off. There were drawbacks such as causing it. In addition, in order to improve such defects, attempts have been made to combine specific film-forming polymers (see, for example, Patent Document 1), but further improvement in effect has been desired.

  The hair cosmetic composition of the present invention has a texture that stretches and conforms to the hair, gives the hair a moist feeling and a smooth finish that is not sticky, and has good set retention.

  Hereinafter, embodiments of the present invention will be described in detail.

  The component (A) carboxyvinyl polymer and / or acrylic acid / alkyl methacrylate copolymer used in the present invention has a property of increasing viscosity by alkali neutralization.

  The amount of component (A) carboxyvinyl polymer and / or acrylic acid / alkyl methacrylate copolymer used in the present invention is 0.1 to 5% by mass (hereinafter abbreviated as%) based on the total amount of hair cosmetics. Are preferred). If it is within this range, a preferable viscosity for use can be obtained.

  The component (A) carboxyvinyl polymer and / or acrylic acid / alkyl methacrylate copolymer used in the present invention is preferably used by adjusting the pH with an alkali, neutralizing it and increasing the viscosity. The alkali as the neutralizing agent is not particularly limited, and examples thereof include alkanolamines such as diisopropanolamine, triethanolamine and aminomethylpropanol, potassium hydroxide and sodium hydroxide.

  Specific examples of the carboxyvinyl polymer used in the present invention include “Sintalen” series [manufactured by 3V SIGMA], “Carbopol” series [B. F. Manufactured by Goodrich Co., Ltd.], and specific examples of acrylic acid / alkyl methacrylate copolymers include "Penylene" series [B. F. Etc.].

If the blending amount is less than 0.5%, the set retention may be insufficient. If the blending amount exceeds 10%, hair may be cured, which is not preferable.

  Examples of the component (C) nonionic film forming resin used in the present invention include polyvinylpyrrolidone, vinylpyrrolidone / vinyl acetate copolymer, and the like. In general, a nonionic film-forming resin is effective for holding a set of hair and imparting a smooth texture because the film is flexible and has high re-solubility in water. Examples of polyvinyl pyrrolidone include Luviskol K series [manufactured by BASF] and PVP K series [manufactured by ISP]. Examples of vinyl pyrrolidone / vinyl acetate copolymers include Luviskol VA series [manufactured by BASF], PVP / VA Series [made by ISP] etc. are mentioned.

Is represented by an integer from 500 to 2,500, the molecular weight is about 20,000 to 20 about 250,000.

  In recent years, silicon gum types with p + q exceeding 3,000 have been developed, but the silicone gum type is not preferable because it accumulates in the hair by repeated use. Specifically, dimethylpolysiloxane, methylphenylpolysiloxane, dimethiconol, terminal hydroxyl group methylphenylpolysiloxane, amino group or ammonium group-modified silicone, etc. with a fluid viscosity that does not reach a soft rubber shape at room temperature, 25 ° C. In which a viscosity of 10,000 to 3,000,000 mm2 / s is shown. These highly polymerized silicones are commercially available. Examples thereof are KF-96H (10,000 cs to 1 million cs), KF-8015, KF-8017, KF-8020, Toray Dow Corning, manufactured by Shin-Etsu Chemical Co., Ltd. Examples thereof include SH200C (10,000 cs to 3.5 million cs) manufactured by GE, TSF-451 (6,000 cs to 3 million cs) manufactured by GE Toshiba Silicones, TSF4707, TSF4705, and the like.

  In the present invention, one or two or more of these highly polymerized silicones can be appropriately selected and used. The blending amount of the highly polymerized silicone is 0.1 to 0.1 on the basis of the total amount of the hair cosmetic. 10% is preferable, and 0.5 to 5% is particularly preferable. If it is less than 0.1%, the effect of imparting a smooth feel to the hair may be insufficient, and if it exceeds 10%, it may be unfavorable due to wrinkles and the like.

  In addition to the above essential components, the hair cosmetic of the present invention, if necessary, components generally used in cosmetics, for example, other surfactants, polymer compounds, fats and oils, powders, silicones, pH adjusting agent, moisturizing agent, ultraviolet absorber, ultraviolet dispersing agent, pigment, liquid alcohol, plant extract, bactericidal agent, preservative, antioxidant, chelating agent, drug, perfume, etc., within the range not impairing the effect of the present invention Can be used.

  EXAMPLES Next, although an Example demonstrates this invention concretely, the technical scope of this invention is not limited by these Examples. In addition, the compounding quantity of a composition is shown by the mass%.

  The evaluation test methods and evaluation criteria performed in this example are as follows.

(1) Elongation 1.0 g of hair cosmetics was applied to a hair bundle composed of hair having a length of 30 cm / 5 g, and the elongation was evaluated according to the following criteria.

Judgment criteria ◎: Very good ○: Good △: Slightly good ×: Bad

(2) Setting force 0.5 g of hair cosmetics is uniformly applied to a hair bundle consisting of hair of 15 cm / 1 g in length, wound on a rod of 2 cm in diameter, and left in a constant temperature room at 45 ° C. for 6 hours to completely Dried. After drying, the rod was removed and the apparent length (L) of the hair bundle was measured. Next, the hair bundle was hung in a constant temperature and humidity chamber at 25 ° C. and 90% humidity, taken out after 30 minutes, and the apparent length (L0) of the hair bundle was measured again. Based on the measured value, the set force was determined by the following equation.
Setting force (%) = (15−L0) ÷ (15−L) × 100
(The closer this value is to 100%, the higher the set force is.)

Evaluation criteria ◎: Very good setting power 80% or more ○: Good setting power 50% or more, less than 80% △: Slightly poor setting power 30% or more, less than 50% ×: Poor setting power 30% or less

(3) Sensory evaluation For the 20 expert panels, the hair cosmetics of the examples and comparative examples were used, a sensory test was conducted on the items of smoothness and non-stickiness, and the evaluation was made according to the criteria shown below. I did it.

Judgment criteria (a) Smoothness ◎: More than 15 panelists are judged to be smooth ○: More than 10 panelists and less than 15 are judged to be smooth △: More than 5 panelists are less than 10 ×: Judged that 15 or more people on the panel are not smooth (b) No stickiness ◎: Judged that 15 or more people on the panel were not sticky ○: 10 or more people on the panel and less than 15 people were not sticky △: More than 5 panelists and less than 10 panelists judged not sticky ×: More than 15 panelists judged sticky
