Description

  The present invention relates to a hair cosmetic containing a dextrin fatty acid ester, an amino-modified silicone and a highly polymerized silicone compound having a high ratio of a specific branched saturated fatty acid, and more specifically, a hair cosmetic suitable for use in a rinse, a conditioner or the like. It is about.

  In recent years, with the growing awareness of hair care, cosmetics for treatments such as rinses and conditioners are desired to have higher finishing effects such as smoothness, suppleness, and emollient. Technology is disclosed. For example, using a cationic polymer or a silicone derivative, a technique for enhancing the flexibility of the finish (for example, see Patent Documents 1 to 3), or a technique for imparting an emollient feeling to the finish using a hydrocarbon oil (for example, , See Patent Document 4). In addition, there is a technique for blending amino-modified silicone in order to improve the smoothness of the finish (see, for example, Patent Document 5). Moreover, there exists a technique which uses together a high polymerization silicone and a low polymerization silicone (for example, refer patent document 6).

  On the other hand, dextrin fatty acid esters having a low proportion of branched saturated fatty acids have been conventionally blended in lipsticks, eyeliners, mascaras, foundations and the like as oil gelling agents (see, for example, Patent Document 7).

JP-A-6-312915 JP-T-2001-504136 JP-A-6-80538 JP-A-6-135823 Japanese Patent Laid-Open No. 2006-143661 JP 2005-179337 A Japanese Patent No. 3019191

  However, in the technique using a cationic polymer, if it is contained in a large amount for the purpose of imparting a smoother and more suppleness, there may be a case where the hair is rather stiff due to the adsorption of the cationic polymer to the hair. Further, in the technique using a silicone derivative, the silicone derivative itself is difficult to dissolve in general oil, and the dosage form that can be contained may be limited, and it is necessary to contain it as an emulsion pre-emulsified in water. It could be complicated. Furthermore, with the technique using hydrocarbon oil, it is possible to obtain an emollient feeling, but it is difficult to obtain a good feeling of use because it feels sticky after use due to the oil or has a heavy finish. On the other hand, the technique using amino-modified silicone is superior in the smoothness of the finish, and can smooth the hair surface, but it is difficult to improve the effect of containing hair repairing ingredients, etc. was there. In addition, the technology using a combination of high-polymerized silicones and low-polymerized silicones is excellent in dispersibility of silicones, and it is possible to impart smoothness peculiar to silicones to the hair. In some cases, there was a problem in compatibility.

  On the other hand, dextrin fatty acid esters having a low proportion of branched fatty acids have been used as oil gelling agents, but there is no disclosure of a technique for increasing the proportion of branched fatty acids to be used as a hair conditioning agent.

  Thus, with these conventional techniques, it has been difficult for hair cosmetics to have both a conditioning effect and a good feeling of use, and to make hair repair components act effectively on the hair.

  For this reason, the development of a hair cosmetic that is excellent in smoothness, suppleness, and emollient finish, has a high conditioning effect, has no stickiness, has a light finish, and has an excellent hair repair effect. Therefore, it is an object of the present invention to solve this problem.

Silicones such as amino-modified silicone and highly polymerized silicone can give particularly excellent effects on smoothness and the like on the hair. These are excellent in compatibility with silicone oils, and are excellent in the effect of imparting smoothness to hair, but are not compatible with oils that are non-silicone oils that can be contained in hair cosmetics. There is. In particular, as the content of silicones increases, this tendency may become significant.
In view of the above situation, as a result of intensive studies, the present inventors have uniformly dispersed these silicones in oils other than silicone oils contained in hair cosmetics, and have excellent affinity for hair. As a result of investigating the third essential component that can be used, it was found that a specific dextrin fatty acid ester has an effect.
Furthermore, it has been found that by incorporating a hair repair component into the composition, the effect of hair repair can be remarkably improved, and a hair cosmetic that can solve the above problems can be obtained, and the present invention has been completed.

(Hereafter, it may be simply referred to as “new dextrin fatty acid ester”.)

The component (a) novel dextrin fatty acid ester used in the present invention has the following characteristics.

“Liquid oil does not gel” means that when liquid paraffin having a kinematic viscosity of 8 mm ² / s at 40 ° C. according to ASTM D445 measurement method is used as a liquid oil, 5% by mass of dextrin fatty acid ester (hereinafter, simply “%”). When the viscosity of the liquid paraffin contained is dissolved at 100 ° C. and measured at 25 ° C. after 24 hours, the viscosity is Yamaco DIGITAL VISCOMATE viscometer VM-100A (vibration type) (manufactured by Yamaichi Electronics Co., Ltd.) Is below the detection limit. In addition, when gelatinizing, it can confirm by detecting a viscosity.

(2) The film formed by the novel dextrin fatty acid ester has a specific range of adhesion (tackiness).
The “tackiness” is determined by applying the dextrin fatty acid ester to a support and bringing the other support into surface contact from a state where they are separated from each other, then retracting them and separating them. When expressed by the load change (maximum stress value) applied to the contact point until the film is formed, a light liquid isoparaffin solution containing 40% of the dextrin fatty acid ester is formed on a glass plate with a 400 μm-thick applicator and dried. Texture analyzer, for example, texture analyzer TA. Using XTplus (manufactured by Stable Micro Systems), a probe made of a 12.5 mm diameter cylindrical polyacetal resin (manufactured by Delrin (registered trademark) DuPont) was used as a probe, and a load of 100 g was applied after 10 seconds.

Moreover, the comparative product 2 containing the dextrin fatty acid ester used as a gelling agent instead of the novel dextrin fatty acid ester of the present invention has a “feel of use (no stickiness)”, “smoothness after finishing” ”And“ flexibility after finishing ”, and it was difficult to dissolve when contained, and the stability such as crystal precipitation after production was not good. Comparative product 3 containing amino-modified silicone but not containing highly polymerized silicone compound, Comparative product 4 containing highly polymerized dimethylpolysiloxane but not containing amino-modified silicone, and containing highly polymerized dimethicone, but amino-modified silicone The comparative product 5 containing no was not satisfactory in all of the items of “use feeling (no stickiness)”, “smoothness after finishing”, and “softness after finishing”. In addition, none of the comparative products was satisfactory in “hair repair effect”.
