[0170] The hair cosmetics containing the ingredients shown in the following Table 1 and Table 2 were prepared according to the method described later. For the obtained hair cosmetics, the appearance, spreadability during application, dripping, absorption during application, stickiness during application, smoothness of finishing, and finger passing were evaluated according to the above criteria. Is the smoothness good? These results are listed in Table 1 and Table 2 together.

[0171] In the present invention, by preparing an oil-in-water emulsified cosmetic containing a high-molecular polysiloxane-containing oil in a high blending amount, it is possible to achieve both ease of affinity, spreadability, and hair care effects on the hair surface.

Abstract

Provided is an oil-in-water emulsion-type hair cosmetic which is highly compatible with the hair and easily spreadable thereon, does not fall in drops in using, and has a transparent or translucent and beautiful gel-like appearance while having a rich texture and exerting a high repairing effect comparable to oil-based hair-care products. The oil-in-water emulsion-type hair cosmetic, comprises: (a) 0.1 to 10 mass% of a silicone compound selected from among a high-molecular silicone having a gummy nature or a viscosity of 1,000,000 cs or higher, a silicone hydroxyl-modified at both ends, an amino-modified silicone, an ammonium-modified silicone and a polyalkylene glycol-modified silicone; (b) 0.5 to 79 mass% of dimethylpolysiloxane having a viscosity of 100 cs or lower; (c) 1 to 25 mass% of a polyhydric alcohol; and (d) 1 to 10 mass% of a hydrophilic surfactant, wherein the content of the oily phase is 50-80 mass%, and the composition ratio by mass of (a) to (b) is 1:100 to 1:5.

Description

Technical field [0001] The present invention relates to an oil-in-water emulsified hair cosmetic, and more specifically, to an oil-in-water emulsified hair cosmetic that is used as a care agent or a conditioning agent and has a good use feeling. Background technique [0002] In the past, it was considered that silicone oil is effective for improving hair tip damage caused by combing hair or perming, or for improving the feeling of use, and a combination of high molecular weight polysiloxane and low boiling point oil is widely used (Patent Document 1). [0003] Especially in recent years, hair dyeing has become more and more normal, and hair damage has become more serious. It is necessary to use hair cosmetics to improve and repair damaged hair. [0004] We know that for hair that has been dyed, the fat layer on the hair surface is hydrolyzed due to the influence of the oxidizing agent such as hydrogen peroxide contained in the hair dye to generate cysteine ​​and become hydrophilic. ...
