Description

  The present invention relates to an oily composition suitable for use in a mode in which the composition is applied to hair and not washed off, and a hair treatment method using the composition.

  As the hair composition, an oily composition containing decamethylcyclopentasiloxane is known (see Patent Document 1). In such an oily composition, it may be necessary to add water. For example, when it is desired to add a water-soluble component, if water is added, the water-soluble component itself is dissolved in water, and the dispersibility of the water-soluble component in the oily composition is increased.

  However, when decamethylcyclopentasiloxane and water coexist, water is incompatible with decamethylcyclopentasiloxane, and therefore, a situation occurs where water separation or water dispersibility is insufficient. This situation gives rise to inconveniences such as poor uniform applicability of the hair composition.

  The present applicant has proposed a technique related to an oil-based composition in which water is dispersed in decamethylcyclopentasiloxane in Patent Document 2. The proposal includes water, polyether-modified silicone having an HLB value of 3.5 to less than 6.0, decamethylcyclopentasiloxane, and polyoxyethylene alkyl ether having an HLB value of 6.5 to 10.5. (Refer to claim 1 and claim 5 of patent document 2). Although such proposals are being made, there are cases where improvement in the feel of hair by the blended components is required, and other technical proposals that enhance water dispersibility are desired. Moreover, even if it is a component which improves the dispersibility of water, it is also desired that the dispersibility of the component itself is high.

  In addition, when using as a hair composition of the aspect which does not wash away the oil-based composition of this embodiment, it is used by apply | coating to wet hair or dry hair, and making it dry. The hair at this time may be any of hair having a history of permanent treatment, coloring treatment or bleaching treatment, and hair having no history of such treatment.

  Hereinafter, although the oil-based composition which concerns on this invention is demonstrated based on an Example, this invention is not limited to a following example.

(Oil composition)
Polyglyceryl-3-polydimethylsiloxyethyl dimethicone (“KF-6104” manufactured by Shin-Etsu Silicone Co., Ltd.), PEG-10 dimethicone with HLB4.5, PPG-4-ceteth-1 with HLB 9.5, polyglyceryl isostearate 2, Laures-2 with an HLB of 9.5, Ores-2 with an HLB of 7.5, Seths-7 with an HLB of 11.5, Laures-9 with an HLB of 14.5, water, trehalose, Ingredients selected from PEG-150 (polyethylene glycol having an average addition mole number of 150), lauryl betaine, and decamethylcyclopentasiloxane were blended in the blending amounts shown in Table 1 below, and oil compositions of Examples and Comparative Examples Manufactured. In this production, the oil-based composition was produced by performing ultrasonic stirring using an ultrasonic cleaner “ASU-10” manufactured by AS ONE for about 30 minutes.

(appearance)
About the oil-based composition of an Example and a comparative example, after inject | pouring into the colorless and transparent screw about 4 cm in diameter and a capacity | capacitance about 100 ml, the external appearance was confirmed visually. Appearance was confirmed immediately after production and after 50 days at room temperature after production.

Table 1 below shows the results of appearance confirmation together with the components and amounts blended in the oil compositions of Examples and Comparative Examples.

  Regarding the appearance immediately after the production, in Table 1 above, the oil compositions of Examples 1a to 1e corresponding to the present invention are “slightly cloudy” or “transparent”, and thus are Comparative Examples 1a to 1b that are “cloudy”. It can be confirmed that the dispersibility of water, a surfactant, and the like was higher than that of the oily composition (the higher the transparency, the higher the dispersibility). And although Example 1a was "slightly cloudy", Examples 1b-1e were "transparent". This is because polyglyceryl-3-polydimethylsiloxyethyl dimethicone and a mixture of higher fatty acid and diglycerin ester (Example 1b), polyglyceryl-3-polydimethylsiloxyethyl dimethicone and HLB are 6.5 or more and less than 10.5. Polyoxyethylene alkyl ether blends (Examples 1c and 1d), polyether-modified silicones having an HLB of 3.5 or more and less than 6.0 represented by the general formula (1), and HLB of 6.5 or more and 10.5 Less polyoxyethylene polyoxypropylene alkyl ether blend (Example 1e) means that water and surfactants were easily dispersed in the production process.

  Moreover, the result is shown in the said Table 1 and FIG. 1 regarding the external appearance after 50-day progress. That is, since the oily compositions of Examples 1a to 1e corresponding to the present invention are “slightly cloudy” or “transparent”, the oily compositions of Comparative Examples 1a to 1b that were “coarse particle precipitation” or “cloudy”. It can be confirmed that the dispersibility of water and surfactants was higher than that of the product over a long period of time. And although Example 1b was "slight cloudiness", Example 1a, 1c-1e was "transparent". This is the combination of polyglyceryl-3-polydimethylsiloxyethyl dimethicone and polyoxyethylene polyoxypropylene alkyl ether having an HLB of 6.5 to less than 10.5 (Example 1a), polyglyceryl-3-polydimethylsiloxyethyl dimethicone. And a polyoxyethylene alkyl ether compound having an HLB of 6.5 or more and less than 10.5 (Examples 1c and 1d), and a polyether having an HLB of 3.5 or more and less than 6.0 represented by the general formula (1) Meaning that the blend of the modified silicone and the polyoxyethylene polyoxypropylene alkyl ether having an HLB of 6.5 or more and less than 10.5 (Example 1e) had high dispersibility of water, surfactant, etc. over a long period of time. To do. In addition, when the transparency of Example 1a, 1c-1e is compared, Example 1a and Example 1e are equivalent, Example 1a is more transparent than Example 1c, Example 1c is more transparent than Example 1d The nature was high.
