Description

[Technical field]

[0001] The present invention relates to a liquid temporary hair dye composition. [Background technology]

[0002] Temporary hair dyes are hair dyes that color the hair by forming a colored film containing a coloring agent (mainly a pigment) on the hair. They are popular because they cause little damage to the hair, can be easily removed by washing, and are easy to use, allowing you to enjoy hair dyeing without any hassle.

[0003] Conventionally, in order to make a temporary hair dye develop a beautiful color on the hair and maintain that color, a sufficient amount of a colorant such as a pigment and a fixing agent (polymer, etc.) that fixes the colorant on the hair as a colored film have been used (e.g., Patent Document 1). In addition, in order to apply the hair dye composition to the hair simply and beautifully, it is often used in combination with a carrier such as a nonwoven fabric, paper, or sponge (e.g., Patent Document 2).

[0004] [Patent Document 1] JP 2017-114815 A [Patent Document 2] JP 2018-033935 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the addition of a sufficient amount of pigment or fixative may cause the pigment to aggregate over time, making it impossible to ensure sufficient color development. In particular, when a large amount of lower alcohol is used as a solvent, the pigment is likely to aggregate or settle. In order to suppress the aggregation of the pigment, a dispersant, a thickener, or the like is used as a base, but most of these bases may cause changes in the properties of the agent, such as stickiness or adhesion, have a negative effect on the application, or inhibit the ability to fix the agent to hair, making it impossible to maintain sufficient color development.

[0006] In particular, when a hair dye composition using a large amount of lower alcohol as a solvent is used in combination with a support, there is a problem that the pigment aggregates and settles in the support, and the pigment is not properly discharged, making it impossible to ensure sufficient application properties and finish.

[0007] Therefore, the present invention relates to a liquid temporary hair dye composition which, despite containing a large amount of a lower alcohol, is resistant to pigment aggregation or precipitation and ensures sufficient color development. [Means for solving the problem]

[0008] In view of this situation, the inventors have conducted extensive research to suppress the aggregation and precipitation of pigments in large amounts of lower alcohols, and have found that by using crystalline cellulose together with the pigment, it is possible to suppress the aggregation and precipitation of the pigment, and to maintain color development without impairing coatability or color development.

[0009] The present invention provides a liquid temporary hair dye composition containing the following components (A) to (C), with the content of component (C) being 50 mass % or more. (A): Pigment (B): Crystalline cellulose (C): Monohydric alcohol having 1 to 4 carbon atoms

[0010] The present invention also provides a temporary hair dye cosmetic product comprising the above liquid temporary hair dye composition supported on a fiber structure. Effect of the Invention

[0064] Synthesis Example 1: Polysilicone-9 A 0.77g (0.005 mol) of diethyl sulfate and 12.9g (0.13 mol) of 2-ethyl-2-oxazoline were dissolved in 28g of dehydrated ethyl acetate and heated under reflux for 8 hours under a nitrogen atmosphere to synthesize terminally reactive poly(N-propionylethyleneimine). The number average molecular weight was measured by GPC and found to be 2700. A 33% ethyl acetate solution of 100g of side chain primary aminopropyl modified polydimethylsiloxane (weight average molecular weight 100,000, amine equivalent 20,000) was added all at once and heated under reflux for 10 hours. The reaction mixture was concentrated under reduced pressure to obtain N-propionylethyleneimine-dimethylsiloxane copolymer as a colorless solid (108g, yield 95%). The organopolysiloxane segment content of the final product was 88% by mass, and the weight average molecular weight was 114,000. Neutralization titration with hydrochloric acid using methanol as the solvent revealed that no amino groups remained.

[0065] Synthesis Example 2: Polysilicone-9 B 6.5g (0.042 mol) of diethyl sulfate and 34.4g (0.36 mol) of 2-ethyl-2-oxazoline were dissolved in 87g of dehydrated ethyl acetate and heated under reflux for 8 hours under a nitrogen atmosphere to synthesize terminally reactive poly(N-propionylethyleneimine). The number average molecular weight was measured by GPC and found to be 1000. A 33% ethyl acetate solution of 100g of side chain primary aminopropyl modified polydimethylsiloxane (weight average molecular weight 50,000, amine equivalent 2,000) was added all at once and heated under reflux for 10 hours. The reaction mixture was concentrated under reduced pressure to obtain N-propionylethyleneimine-dimethylsiloxane copolymer as a pale yellow solid (138g, yield 98%). The organopolysiloxane segment content of the final product was 71% by mass and the weight average molecular weight was 70,000. Neutralization titration with hydrochloric acid using methanol as the solvent revealed that approximately 20 mol % of amino groups remained.

[0066] Synthesis Example 3: Polysilicone-9 C 6.17g (0.04 mol) of diethyl sulfate and 93.8g (0.947 mol) of 2-ethyl-2-oxazoline were dissolved in 203g of dehydrated ethyl acetate and heated under reflux for 8 hours under a nitrogen atmosphere to synthesize terminally reactive poly(N-propionylethyleneimine). The number average molecular weight was measured by GPC and found to be 2500. A 33% ethyl acetate solution of 100g of side chain primary aminopropyl modified polydimethylsiloxane (weight average molecular weight 30,000, amine equivalent 2,000) was added all at once and heated under reflux for 10 hours. The reaction mixture was concentrated under reduced pressure to obtain N-propionylethyleneimine-dimethylsiloxane copolymer as a pale yellow solid (190g, yield 95%). The organopolysiloxane segment content of the final product was 50% by mass and the weight average molecular weight was 60,000. Neutralization titration with hydrochloric acid using methanol as the solvent revealed that approximately 20 mol % of amino groups remained.

[0067] Examples 1 to 29, Comparative Examples 1 to 4 Liquid temporary hair dye compositions were prepared according to the compositions shown in Tables 1 and 2. The liquid temporary hair dye compositions other than those of Example 12 and Comparative Example 2 were impregnated into a nonwoven fabric carrier to form a nonwoven fabric carrier, which was then used for each evaluation. The nonwoven fabric carrier used here had a basis weight of 45.0±4.5 g / m 2 , thickness 0.60±0.20 mm, size 3cm×5cm (SH Crepe 45, Ikeda Paper Co., Ltd.) and basis weight 60.0±6.0 g / m 2 The thickness is 0.54±0.06 mm and the size is 3cm × 5cm (RB8260P, manufactured by Ikeda Paper Co., Ltd.).

[0068] <Manufacturing method> (Preparation of Liquid Temporary Hair Dye Composition) The liquid temporary hair dye compositions were produced by the following production methods a, b, or c. ·Manufacturing method a In the presence of component (C), components (A), (B) and (D) were crushed using a bead mill (Nano Mill NM-L, manufactured by Asada Iron Works). Then, component (E) and other components were added to the crushed mixture and mixed to obtain a liquid temporary hair dye composition. Examples 14, 24, 25 and Comparative Example 3 were prepared in the same manner as above, but without adding component (D). Comparative Examples 1 and 2 were prepared in the same manner as above, but without adding components (B), (D) and (E). ·Manufacturing method b In the presence of component (C), components (B) and (D) were crushed using a bead mill (Nano Mill NM-L, manufactured by Asada Iron Works). Then, component (A) was added to the crushed composition and mixed, and further, component (E) and other components were added and mixed to obtain a liquid temporary hair dye composition. In Comparative Example 4, component (A) was added to component (C) and mixed to obtain a liquid temporary hair dye composition. ·Manufacturing method c In the presence of component (C), component (A) was crushed using a bead mill (Nano Mill NM-L, manufactured by Asada Iron Works, Ltd.). Similarly, in the presence of component (C), components (B) and (D) were crushed. Thereafter, the mixture of crushed components (A) and (C) was mixed with the mixture of crushed components (B), (C), and (D), and component (E) and other components were added and mixed to obtain a liquid temporary hair dye composition.

[0069] (Preparation of Nonwoven Fabric Support) When two types of nonwoven fabric were used, four layers of each type were stacked for a total of eight layers, and when only one type of nonwoven fabric was used, eight layers of that type were stacked and then bonded together. The nonwoven fabric layers were bonded using ultrasonic sealing.

[0070] (Preparation of nonwoven fabric carrier) The uniformly mixed liquid temporary hair dye composition was dropped onto the nonwoven fabric carrier to allow it to soak in. The amount of the liquid temporary hair dye composition held by the nonwoven fabric carrier was adjusted to 333% of the basis weight of the nonwoven fabric carrier.

[0071] <Evaluation method> (Hair bundle for evaluation) A hair bundle of 25 cm in length and weighing 1 g was prepared from straight Japanese hair with no history of chemical treatment. The hair bundle was washed with the model shampoo with the following formulation. The hair bundle was towel-dried and then dried for 1 minute with a hair dryer (Panasonic, Hair Dryer Ionity: EH-NE67) before being used for evaluation.

[0072] (Method for evaluating the effect of suppressing color change after storage) Using a nonwoven fabric carrier carrying the liquid temporary hair dye composition immediately after production, 0.3 g of each composition was spread over the hair bundle for evaluation described above from the root to the tip of the hair bundle. For the liquid temporary hair dye compositions of Example 12 and Comparative Example 2, 0.3 g of each composition was spread over the hair bundle for evaluation from the root to the tip of the hair bundle with fingers without impregnating the nonwoven fabric carrier. After application, the composition was left at room temperature and the hair bundle was thoroughly dried, and this was used as the reference product. On the other hand, the nonwoven fabric carrier carrying the liquid temporary hair dye composition (liquid temporary hair dye composition for Example 12 and Comparative Example 2) was sealed and stored for 7 days in a thermostatic chamber (EYELA windy oven) set at 60°C. The sample was then removed from the thermostatic chamber and left to stand at room temperature for 3 hours to adjust the temperature. After storage, the sample was similarly spread on a hair bundle for evaluation and dried. The color development (intensity) from one end (upper part) of the tied side of the hair bundle to the tip (lower part) of the hair bundle for evaluation was visually observed and evaluated in comparison with a reference product. Evaluation was performed by a panel of five people using the following four-level visual evaluation, and the total score is shown in the table. 4 points: Shows the same color (intensity) as the standard product 3 points: Color (intensity) is slightly lower than the standard product 2 points: Color (intensity) is lower than the standard product 1 point: Color (intensity) significantly decreased compared to the standard product

[0073] (Color development) The color development of the colored hair bundle was visually evaluated by five panelists on the following four-level scale, and the total scores are shown in the table. 4 points: The original hair color is hidden and the color is fully developed. 3 points: The original hair color is slightly concealed and the color is visible 2 points: The original hair color is not concealed well and the color is not very prominent. 1 point: No color at all

[0074] (quick drying) Using a nonwoven fabric carrier carrying the liquid temporary hair dye composition, 0.3 g of each composition was applied to the hair bundle for evaluation shown above from the root to the tip of the hair bundle. For the liquid temporary hair dye compositions of Example 12 and Comparative Example 2, 0.3 g of each composition was applied to the hair bundle for evaluation from the root to the tip with fingers without impregnating the nonwoven fabric carrier. After application, a comb (Kai Corporation, HK0103 B's Set Comb L) was passed through the hair bundle once per second, a total of five times, and then the hair bundle was left to dry at room temperature. The speed of drying was evaluated based on the state of the hair bundle when touched with the fingers. The evaluation was performed by five panelists on a four-level visual evaluation scale, and the total score is shown in the table. 4 points: Quick drying 3 points: Dries rather quickly 2 points: Doesn't dry very quickly 1 point: Slow drying

[0075] (Touch) After evaluating the quick-drying property, the dried colored hair bundle was combed (Kai Corporation, HK0103 B's Set Comb L) once per second, a total of 10 times. The hair bundle was touched with the fingers and evaluated for stickiness and stiffness on the fingers according to the following criteria. Evaluation was performed by five panelists on a four-point scale, and the total score is shown in the table. 4 points: Not sticky or stiff, smooth and slippery 3 points: Almost no stickiness or stiffness, and slightly smooth 2 points: Feels a bit sticky and stiff, and has poor slipperiness 1 point: Sticky and stiff, not slippery

[0076] (Applicability) The applicability of the nonwoven fabric carrier carrying the liquid temporary hair dye composition (Example 12 and Comparative Example 2 were not evaluated because the nonwoven fabric carrier was not impregnated with the liquid temporary hair dye composition) was evaluated by visually observing the finish from one end (upper part) of the tied side of the evaluation hair bundle to the tip (lower part). The evaluation was made by five panelists on the following four-point scale, and the total score is shown in the table. 4 points: The finish is uniform from top to bottom 3 points: Fairly uniform finish from top to bottom 2 points: The finish is not very uniform from top to bottom. 1 point: The finish is not uniform from top to bottom

[0077] (Method of evaluating redispersibility) The liquid temporary hair dye composition was stored in a sealed container (centrifuge tube) and stored in a thermostatic chamber (EYELA windy oven) set at 60°C for 7 days. The sample was then removed from the thermostatic chamber and allowed to stand at room temperature for 3 hours to adjust the temperature. After storage, the sample was shaken for 30 seconds, and the state of the sediment was visually observed to evaluate redispersibility. Evaluation was performed by five panelists on the following four-point scale, and the total score is shown in the table. 4 points: No sediment remains and the mixture is uniformly mixed 3 points: Almost no sediment remains and the mixture is almost uniform 2 points: There is not much sediment remaining, but it is not evenly mixed 1 point: A large amount of sediment remains and is not mixed uniformly
