As the component (B), a commercially available component may be used.

The blending amount of the component (B) is not particularly limited as long as the effect of the present invention can be exhibited, but it is preferably 0.1 to 10.0% by mass with respect to the conditioning composition. When the blending amount is 0.1% by mass or more, the moist feeling of the hair at the time of drying is good, and when it is 10.0% by mass or less, the smooth feeling of the hair at the time of drying is good.

<(C) Solid oil at 25 ° C, which is not a linear saturated higher alcohol>
The component (C) used in the conditioning composition of the present invention is an oil agent in a solid state at 25 ° C. The solid state at 25 ° C. means a substance having a melting point of 26 ° C. or higher and a constant volume and shape at 25 ° C. or lower. The component (C) is mainly used to contribute to the smooth feeling of hair when it is dried. Further, the linear saturated higher alcohol refers to alcohols having 12 or more carbon atoms and having no branching or unsaturated.

The oil agent of the present invention, which is not a linear saturated higher alcohol and is solid at 25 ° C., is not limited to these, but specifically, stearyl stearate, pentaerythrityl distearate, cetyl palmitate, and hydrogenation. Examples thereof include palm oil, hexa (behenic acid / benzoic acid / ethyl caproic acid) dipentaerythrityl, paraffin, cocoa fat and the like, and one or a combination of two or more of these can be used. As the component (C), a commercially available component may be used.

The blending amount of the component (C) is not particularly limited as long as the effect of the present invention can be exhibited, but it is preferably 0.1 to 10.0% with respect to the conditioning composition. When the blending amount is 0.1% by mass or more, the smooth feeling of the hair at the time of drying is improved, and when it is 10.0% by mass or less, the softness of the hair at the time of drying is good.

In each of the oils (A), (B) and (C), it is preferable to use an ester oil from the viewpoint of no squeaking during rinsing.

Therefore, the conditioning composition containing the silicone component of the present invention suppresses build-up and softens the hair after drying by combining the above-mentioned specific components (A), component (B), and component (C). It exerts both the inherently contradictory characteristics of build-up and conditioning effects, such as moisturizing, slippery feeling, and maintaining the absence of squeaks during rinsing.

This effect is presumed to be due to the following actions. That is, in the silicone component-containing conditioning composition, the oils (A), (B), and (C) are mutually soluble, and the solubility of the silicone component is also improved. Persistence on hair is reduced compared to when no oil is included. Therefore, while suppressing build-up, it also has hydrophobicity that is not completely washed away, so it is possible to combine the softness of dried hair, the moist feeling, the smooth feeling, and the absence of squeaky hair during rinsing.

<Other ingredients>
In addition to the above-mentioned components, the conditioning composition of the present invention may contain other components generally blended in the conditioning composition, depending on the purpose, as long as the effects of the present invention are not impaired.
