Description

Technical Field

[0001] The present invention relates to a fiber treatment composition.

Background Art

[0002] In recent years, in addition to chemical treatments such as hair coloring and perming, hair setting using heat from hair irons, dryers, etc., which has become a habit especially among young women, damage, particularly at the hair tips, has been worsening. Hair damage causes hydrophilization of the hair surface and an increase in friction, resulting in problems such as tangling of the hair tips and poor combability during styling. Additionally, as a result of forming cavities inside the hair, the appearance of the hair looks whitish due to diffuse reflection of light, giving an unhealthy impression.

[0003] As a technique for improving the color of damaged hair, Patent Document 1 discloses that by washing the hair with a shampoo containing a water-insoluble modified silicone containing an amino group or a quaternary ammonium group and conditioning, the original color of the hair that has become dull due to damage can be made vivid and its chroma can be increased.

Examples

[0122] Examples 1 to 16, Comparative Examples 1 to 7 Aqueous solutions having the compositions shown in Tables 1 to 3 were prepared, and evaluations were made regarding the film-forming property of these aqueous solutions, as well as the darkening effect and the persistence of the film when treated on hair.

[0123] (Preparation method of each aqueous solution) Purified water and each component were weighed in predetermined amounts in Table 1 into a 200 mL beaker containing a stir bar, and stirred and mixed for 30 minutes or more using a stirrer until the aqueous solution became uniform.

[0124] (Film-forming property evaluation method) 300 μL of each aqueous solution was dropped onto a slide glass and dried in an oven set at 90°C for 30 minutes. Then, after leaving it to stand at room temperature for about 10 minutes, the presence or absence of film formation was confirmed by visual observation and sensory evaluation. A dry film that was not sticky, did not adhere to the hand, and was crispy was rated as "5: very good", a dry film that was not sticky and did not adhere to the hand was rated as "4: good", a dry film with some stickiness was rated as "3: normal", a film with a partially undried part was rated as "2: bad", and a film with a mostly undried part was rated as "1: very bad" for a five-level evaluation.

[0125] (Method for Evaluating Darkening Effect) For the hair for evaluation, damaged hair obtained by subjecting 3.0 g of healthy Caucasian hair tresses to a single treatment with powder bleach (GOLDWELL TOPCHIC) was used. Each aqueous solution shown in Tables 1 to 3 was uniformly applied to the wet tresses after rinsing the hair at a bath ratio of 0.2 (separate tresses were used for each aqueous solution), and completely dried with a dryer without rinsing. Thereafter, using the plain shampoo shown below, the process until drying after washing was defined as one step, and a total of 3 steps were repeated.

[0126] · Composition of plain shampoo (pH 6.9) (mass%) Sodium polyoxyethylene lauryl ether sulfate (Emal 170J, manufactured by Kao Corporation, active ingredient 70 mass%) 13.0 Coconut oil fatty acid monoethanolamide (Amisol CME, manufactured by Kawaken Fine Chemical Co., Ltd.) 0.6 Coconut oil fatty acid amidopropyl carboxybetaine (Anhitol 55AB, manufactured by Kao Corporation, active ingredient 30 mass%) 1.41 Citric acid pH adjustment amount Sodium benzoate 0.3 Purified water balance

[0127] In each tress after the powder bleach treatment, the Lab value, which is a color index, was measured using a color difference meter before and after treating with the aqueous solution. A Konica Minolta CR-400 was used as the color difference meter. The tress was stroked 5 times at a rate of 3 seconds per stroke with a straight iron set at 180°C, and measured in a state where the surface was straight. Using the measured L value, the greater the negative difference (ΔL) in the L value after treatment compared to before treatment with the aqueous solution, the higher the darkening effect. ΔL of 2.5 or more was rated as "5: very high", ΔL less than 2.5 and 1.5 or more was rated as "4: high", ΔL less than 1.5 and 1.0 or more was rated as "3: normal", ΔL less than 1.0 and 0.5 or more was rated as "2: low", and ΔL less than 0.5 was rated as "1: very low", and a five-level evaluation was performed.

[0128] (Method for Evaluating the Persistence of Film) All healthy Japanese hair 1.0 g tres was used for the hair for evaluation. Each aqueous solution shown in Table 1 or 2 was applied to the wet and towel-dried tres at a bath ratio of 0.3 with respect to the hair, and without rinsing, it was completely dried using a dryer. Then, it was washed once using the above-mentioned plain shampoo and completely dried using a dryer. Sensory evaluation of the tres before and after shampoo washing was performed while drying, and the difference in touch was compared. Those with no change in touch even after shampoo washing and no snagging felt from the middle to the hair tip were designated as "A", those with a slight snagging feeling were designated as "B", and those with a snagging feeling were designated as "C".
