Description

[Technical Field]

[0001] The present invention relates to a non-aqueous hair composition and a hair treatment method using the composition. [Background technology]

[0002] Treatment with a non-aqueous hair composition suitable as a leave-in treatment can impart a different feel to hair than aqueous compositions. Volatile cyclic silicones are known as common ingredients incorporated into non-aqueous hair compositions, but due to the increasing global demand for cosmetics, there are concerns about their supply. Under these circumstances, there is a need to reduce the amount of volatile cyclic silicone used. As one response to this, Patent Document 1 proposes a non-aqueous composition for skin or hair that contains an ultraviolet absorber and a liquid hydrocarbon.

[0020] The present invention will be described below based on the embodiments of the present invention. The non-aqueous hair composition according to this embodiment contains the following components (A), (B), and (C), and contains a predetermined amount of component (A): The non-aqueous hair composition according to this embodiment may also contain, as optional components, components that are contained in known non-aqueous hair compositions. (A) Hydrocarbons of a given kinematic viscosity (B) Volatile acyclic silicone and / or isododecane (C) Highly polymerized methylpolysiloxane and / or highly polymerized dimethiconol

[0021] The composition of this embodiment is non-aqueous, and "non-aqueous" means that the external phase of the composition does not have an oil phase or an aqueous phase. Furthermore, since adding water tends to cause separation of the aqueous phase and the oil phase and cloudiness of the composition, it is preferable not to add water. If water is added, the amount of water added is preferably less than 3.0% by mass, preferably less than 1.0% by mass, more preferably less than 0.5% by mass, even more preferably less than 0.1% by mass, and even more preferably less than 0.05% by mass.

[0023] The hydrocarbon component (A) preferably has a flash point of 50°C or higher, 55°C or higher, 60°C or higher, 70°C or higher, or 80°C or higher. The flash point of the hydrocarbon component (A) is preferably 110°C or lower, more preferably 100°C or lower, and more preferably 95°C or lower, in order to improve the ease of running fingers through hair when drying and the softness, smoothness, and moisturized feel of hair after drying. The flash point may be measured by any known suitable method. For example, Japanese Industrial Standard JIS K 2265 discloses that the tag-closed method is suitable for flash point ranges of 93°C or lower, and that the Cleveland open method is suitable for flash point ranges of more than 79°C.

[0024] Component (A) may be one or more types selected from known hydrocarbons. Examples of known hydrocarbons for component (A) include light isoparaffin, light liquid isoparaffin, undecane / tridecane, and (C13-15) alkanes. The amount of component (A) in the non-aqueous hair composition of this embodiment is 15% by mass or more. To improve the moist feeling of hair after drying, it is preferably 20% by mass or more, more preferably 25% by mass or more, more preferably 30% by mass or more, even more preferably 35% by mass or more, and even more preferably 40% by mass or more. Furthermore, to improve the ease of running your fingers through hair during drying and the softness and smoothness of hair after drying, the amount of component (A) is preferably 80% by mass or less, more preferably 70% by mass or less, more preferably 60% by mass or less, and even more preferably 55% by mass or less.

To improve the moist feeling of hair after drying, the amount of light liquid isoparaffin in the non-aqueous hair composition of this embodiment is preferably more than 10% by mass, more preferably more than 20% by mass, more preferably more than 30% by mass, and even more preferably more than 40% by mass. To improve the ease of combing hair during drying and the softness and smoothness of hair after drying, the amount of light liquid isoparaffin in the composition is preferably 80% by mass or less, more preferably 70% by mass or less, more preferably 60% by mass or less, and even more preferably 55% by mass or less.

The non-aqueous hair composition of this embodiment may contain no volatile acyclic silicone or no isododecane, as long as it contains either a volatile acyclic silicone or isododecane. The inclusion of a highly volatile component (B) makes it easier to dry hair to which the non-aqueous hair composition of this embodiment has been applied.

[0027] The volatile acyclic silicone, component (B), does not have a cyclic skeleton in its molecular structure, unlike volatile cyclic silicones such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane.

[0028] When a volatile acyclic silicone (component (B)) is blended, it is preferable to blend one or more types selected from known volatile acyclic silicones. Examples of such volatile acyclic silicones include linear dimethylpolysiloxanes such as trisiloxane, branched silicones such as methyl trimethicone, and silicones having alkyl groups on their side chains such as ethyl methicone. When a volatile acyclic silicone (component (B)) is blended in the non-aqueous hair composition of this embodiment, the blend amount of the volatile acyclic silicone in the composition is preferably 10% to 85% by mass, preferably 15% to 70% by mass, more preferably 20% to 60% by mass, and even more preferably 30% to 50% by mass. A blend amount of volatile acyclic silicone of 10% by mass or more is suitable for improving the ease of running fingers through hair during drying and the softness and smoothness of hair after drying, while a blend amount of 85% by mass or less is suitable for reducing the cost of the non-aqueous hair composition. If isododecane is blended as component (B), the blending amount of the volatile acyclic silicone may be 10% by mass or less, 5% by mass or less, 3% by mass or less, or 1% by mass or less.

The inclusion of component (C) is advantageous for improving the ease of running fingers through hair during drying, as well as the softness, smoothness, and moisturized feel of hair after drying.

[0031] The amount of component (C) in the non-aqueous hair composition of this embodiment is preferably from 1% to less than 15% by mass, and more preferably from 2% to less than 10% by mass. If the amount of component (C) is from 1% to less than 15% by mass, this is suitable for improving the ease of running fingers through the hair when drying, as well as the softness, smoothness, and moist feeling of the hair after drying.

[0032] The highly polymerized methylpolysiloxane of component (C) is a linear polymer with a siloxane bond backbone and an average degree of polymerization of 650 or more, and it is preferable to blend one or more types selected from known highly polymerized methylpolysiloxanes as component (C).

[0033] The highly polymerized dimethiconol of component (C) is a linear polymer having a skeleton of siloxane bonds with terminal hydroxyl groups and an average degree of polymerization of 650 or more. One or more types of known highly polymerized dimethiconols may be blended as component (C). The amount of the highly polymerized dimethiconol blended in the non-aqueous hair composition according to this embodiment may be 1% by mass or more but less than 15% by mass, 2% by mass or more but less than 10% by mass, or 3% by mass or more but less than 5% by mass. A blending amount of component (C) of 1% by mass or more but less than 15% by mass is favorable for improving the ease of running fingers through hair during drying, as well as the softness, smoothness, and moisturized feel of hair after drying.

[0034] (optional ingredient) The non-aqueous hair composition of this embodiment can contain optional components contained in known non-aqueous hair compositions, but due to supply concerns, it is preferable to avoid the inclusion of volatile cyclic silicones such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane, or to limit the amount of these volatile cyclic silicones contained therein.

[0044] (Hair treatment) The hair wash composition was massaged into a hair bundle wetted with running water, and after lathering with a hand comb, the hair wash composition was rinsed off with running water. The hair bundle was then immersed in a mixture of hair wash composition and water in a mass ratio of 1:20, and subjected to ultrasonic cleaning for 30 minutes. The hair wash composition was then thoroughly rinsed off the hair bundle with running water. Next, 0.2 g of any of the compositions of the Examples and Comparative Examples was applied to the wet hair bundle, which had only been wiped dry with a towel, and the hair was then dried with a hair dryer.

[0045] Details of the hair strands and hair wash compositions used in the hair treatment are as follows: Hair bundle: A bundle made by bundling one end of hair collected from a Japanese woman. Each hair bundle is approximately 35 cm long and weighs approximately 10 g. Hair cleansing composition: 10% by weight aqueous solution of "Emar 227HP," a product containing sodium laureth sulfate manufactured by Kao Corporation

[0046] (evaluation) Sensory evaluations were conducted by five evaluators on the following criteria: "Ease of running fingers through hair when dried," "Softness after drying," "Moisture after drying," and "Smoothness after drying." For the evaluation of "Ease of running fingers through hair when dried," the ease of running fingers through the hair strands during the process of drying with a hair dryer during hair treatment was evaluated. For the evaluation of "Softness after drying," the soft feel of the hair strands after treatment and drying with a hair dryer was evaluated. For the evaluation of "Moisture after drying," the moist feel of the hair strands after treatment and drying with a hair dryer was evaluated. For the evaluation of "Smoothness after drying," the smooth feel of the hair strands after treatment and drying with a hair dryer was evaluated. For these evaluations, the evaluators assigned scores on a rating scale, and the average of the scores was used as the evaluation.

[0047] The components, blending amounts, and evaluation results of the compositions according to Examples 1a to 1d and Comparative Examples 1a and 1b are shown in Table 1. The evaluation scale used by the evaluators on which the evaluation results, which are average scores, are based is as follows, with Comparative Example 1a being the standard.

[0054] [Table 3]

[0055] A comparison of Examples 3a to 3c in Table 3 confirms that increasing the amount of light liquid isoparaffin (Component (A)) improved the moist feeling after drying, and a comparison of Examples 3a to 3b with 3c confirms that reducing the amount of Component (A) was optimal for improving the ease of running fingers through the hair when dried, the softness after drying, and the smoothness after drying. Furthermore, a comparison of Examples 3a to 3b with 3c confirms that increasing the amount of Component (B) was optimal for improving the ease of running fingers through the hair when dried, the softness after drying, and the smoothness after drying.

[0056] The components, blending amounts, and evaluation results of the compositions of Examples 4a and 4b are shown in Table 4. The evaluation scale used by the evaluators on which the evaluation results, which are average scores, are based is as follows, with Example 4b being the standard. Better than standard: 2 points Standard or equivalent: 1 point Below standard: 0 points
