Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a complex of a sulfate ester-modified silicone useful as a compounding ingredient of a cosmetic and a specific cationic surfactant, a cosmetic containing the complex, and a cosmetic comprising the complex. It is an invention belonging to the technical field related to hair cosmetics combined and combined with other specific components.

2. Description of the Related Art For modern people, cosmetics are necessities of daily life. With the diversification of lifestyle in recent years, development of cosmetics suitable for various living scenes has been promoted. For example, "Morning Shan" washing hair before going to work or going to school
Since it is preferable to finish in as short a time as possible, `` Rinse in shampoo '' that can perform `` to remove dirt with shampoo and finish with hair rinse '' at once is developed, and many are on the market now . Thus, the development of cosmetics that can be adapted to diversifying lifestyle patterns by adding specific functions to conventional cosmetics is a major trend in modern cosmetics development.

[0003] The background and current status of the development of "rinse-in shampoo", which is a representative cosmetic product to which a new function is added, will be described below. In the first place, using a hair rinse and conditioner after washing hair with shampoo,
This is because when washing hair with shampoo, a minimum of natural oil necessary for hair together with dirt tends to be washed away. In other words, hair rinses and conditioners have been developed to solve problems such as loss of hair gloss, poor combing and styling, and accumulation of static electricity, which tend to accompany hair washing with shampoo. It has been. However, especially in the above-mentioned modern lifestyle, using a hair rinse and a conditioner after washing hair with shampoo also requires time.
I could not deny that there were aspects that were not efficient in terms of cost.

Therefore, recently, attempts have been made to impart a rinsing effect and a conditioning effect to the shampoo itself, and the above-mentioned "rinse-in shampoo" has been developed (Japanese Patent Application Laid-Open No. 63-317596, etc.). Until now, as a rinse component in "Rinse in shampoo",
Mainly cationic polymers have been used. The cationic polymer gives a supple feel when wet and adheres to the hair, but forms a relatively hard coating on the hair when dried. For this reason, although the hair after washing with this “rinse-in shampoo” shows a certain degree of smoothness, there is a disadvantage that little improvement in luster can be expected and a slightly rough feel remains. Also, if this `` rinse in shampoo '' is used more, the slimy feeling of the hair tends to increase, and it does not match the recent consumer's taste, and if it is used less, the rinsing effect will be reduced. There was also a tendency to be extremely reduced.

[0005] In recent years, consumers are changing to a preference for a finished feeling after drying, that is, a smooth and glossy finished feeling and a smooth feeling, rather than the suppression of the squeaky feeling during rinsing. Also, `` rinse-in shampoos '' containing a cationic surfactant are often used for the purpose of imparting hair with smoothness, but these are also poorly adsorbed due to the low molecular weight of the active ingredient, and the effect is poor. In terms of the tendency to be weak, it does not sufficiently give the consumer a sense of satisfaction, and there is also a point that if a large amount is blended, it is not preferable in terms of safety. Further, "rinse-in shampoos" containing oils such as silicone oil, ester oil and mineral oil have been developed for the purpose of imparting gloss, smoothness and luster to hair. In particular, "rinse-in shampoos" containing silicone oils have come to be used particularly frequently because silicone oils are excellent in conformity to hair due to their low surface tension and can also provide good gloss. However, there is a limit to the rinsing effect due to the incorporation of the oil component, and if the oil component is incorporated in a large amount, the hair becomes greasy, and the foaming during shampooing tends to be extremely bad. Also, compositions containing silicone oil were often unstable and tended to separate the silicone oil. In order to solve this problem, various means have been devised for stably blending the silicone oil (JP-A-63-183517, JP-A-4-234309, JP-A-4-243).
No. 810). Although the means for stably blending silicone oil has been solved by these measures, these methods also have limitations, and the blending of silicone oil in a shampoo system causes a reduction in foaming power and detergency. There were also disadvantages.

Next, the background and the current status of the development of hair cosmetics, which are primarily intended to provide a rinsing effect, for which new functions are actively provided, will be described. Hair cosmetics having a so-called "rinse effect" for imparting smoothness and gloss to hair and improving combability are generally commercially available under the names of hair rinse, hair treatment, and hair conditioner. These hair cosmetics usually contain a quaternary ammonium salt, and it is known that the quaternary ammonium salt exerts a rinsing effect by adsorbing on the hair. Further, for the purpose of improving after-use feeling such as smoothness, gloss, and moist feeling, for example, oil components such as higher alcohols, glycerin mono fatty acid esters, higher fatty acids, liquid paraffin, solid paraffin, ester oils, and low molecular weight silicone oils Is added. By appropriately combining and blending these components, a hair cosmetic having smoothness is provided without making the hair sticky.

For example, Japanese Patent Application Laid-Open No. 61-28631 discloses a hair cosmetic containing a specific amount of a mixed component in which a quaternary ammonium salt and a higher alcohol are combined at a specific ratio, and a low-viscosity oil component. It is stated that they provide excellent smoothness to the hair and also provide a non-sticky feel. Japanese Patent Application Laid-Open No. 63-222109 describes a hair cosmetic excellent in washing resistance, containing a quaternary ammonium salt and a high molecular weight silicone belonging to the category of silicone gum in a specific ratio. However, this does not necessarily eliminate the need to further improve the smoothness, flexibility and gloss imparting effect on hair. That is, even if these hair cosmetics can impart smoothness to the hair without stickiness at the time of application and rinsing, it is not always satisfactory when the hair is dried or after the hair is dried. Not exclusively.

[0008]

As described above, with the diversification of modern people's lifestyles, cosmetics have become multifunctional and highly functional. There is not enough support provided. In cosmetics, in order to achieve such multi-functionality and high functionality, it is important to find a new compounding component that supports this.

The problem to be solved by the present invention is to find a new compounding component for realizing the above-mentioned multifunctionality and high functionality in cosmetics, and to further use a multifunctional compound using this compounding component as a basic compounding component. It is an object of the present invention to provide a cosmetic product having improved or advanced functions.

[0010]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems. As a result, a complex comprising a sulfate-modified silicone and a quaternary ammonium salt-type cationic surfactant can be formulated into a cosmetic by blending this with the above-mentioned "rinse-in shampoo" and the cosmetic itself. It has been found that it is possible to achieve multi-functionality and high functionality while maintaining or improving the quality of the present invention, and completed the present invention.

That is, the inventor provides the following invention. Claim 1 provides a composite comprising a sulfate-modified silicone and a cationic surfactant.

[0012] In a second aspect, there is provided a cosmetic comprising the composite according to the first aspect.

[0013] In a third aspect, the present invention provides a hair cosmetic comprising the complex according to the first aspect and an amphoteric surfactant and / or a nonionic surfactant.

[0014] In a fourth aspect, the present invention provides a hair cosmetic comprising the complex according to the first aspect, a mono-long chain alkyl quaternary ammonium salt and an aliphatic higher alcohol.

The same applies to the case where the atom is a chlorine atom. The imidazoline-type quaternary ammonium salt-type cationic surfactant (VII) preferably selected as a component of the complex of the present invention includes lauryl imidazolinium betaine, myristyl imidazolinium betaine, cetyl imidazolinium betaine, stearyl Examples include imidazolinium betaine and behenyl imidazolinium betaine.

The composite of the present invention is obtained by binding the sulfate-modified silicone and the quaternary ammonium salt type cationic surfactant by electrostatic binding.
Can be prepared. Specifically, for example, after sufficiently dissolving a cationic surfactant in an appropriate amount of water with stirring, the sulfate-modified silicone is added, and the mixture is further sufficiently stirred and mixed to form the complex of the present invention. it can.

In the composite preparation system, the mixing ratio of the cationic surfactant and the sulfate-modified silicone (molar ratio: cationic surfactant / sulfate-modified silicone) is 2/8 or more and 7 / The range is 3 or less, preferably 3/7 or more and 5/5 or less.

If the mixing ratio is more than 7/3, the presence of an excess of the quaternary ammonium salt type cationic surfactant undesirably increases irritation to the skin. If the mixing ratio is 2/8 or less, the rinsing effect tends to be inferior, which is not preferable.

In general, a cationic surfactant (for example, the above-mentioned quaternary ammonium salt type cationic surfactant) and an anionic surfactant (for example, sulfonate type anion such as higher alkyl sulfonate) Surfactants, sulfate ester type anionic surfactants such as higher alcohol sulfates, and phosphate ester type anionic surfactants such as polyoxyethylene alkyl ether phosphate) in aqueous solution. , A complex is formed in the crystal phase, the complex becomes a precipitate, and the aqueous solution becomes cloudy or separates.

However, when the complex is allowed to coexist in the solution at a specific molar ratio by combining the sulfate-modified silicone and the quaternary ammonium salt type cationic surfactant as described above, The complex of the present invention is formed in the form of a liquid oil in a solution.

The composite of the present invention exhibits a transparent or translucent oil, and has an advantage of having an excellent rinsing effect and being less irritating to the skin when incorporated in, for example, hair cosmetics. Further, by specifically selecting various combinations as the sulfate-modified silicone and the cationic surfactant constituting the composite of the present invention, it is possible to select the strength of the silicone in the composite of the present invention. is there. That is, it is possible to select and prepare the complex of the present invention according to a specific purpose. In addition, since the silicone-like properties of the composite of the present invention tend to become stronger as it dries, for example, hair cosmetics containing the composite of the present invention have a smooth or slick feel to the hair after use. Can be granted. Furthermore, since foaming is not inhibited even when the composite of the present invention is blended, no inconvenience occurs even when blended in cosmetics requiring foaming such as shampoo. In addition, by appropriately combining the composites of the present invention having different properties as described above and blending them into a cosmetic, it is possible to adjust the usability of the cosmetic.

A two-part hair cosmetic composition comprising a first agent containing a reducing substance and a cationic polymer or an amphoteric polymer and a second agent containing an anionic silicone polymer or the like has been proposed (Japanese Patent Laid-Open Publication No. HEI 9-208). 5-178727,
No. 5-178729). However, such a two-part hair cosmetic composition and the complex of the present invention exhibit excellent effects by dissolving or dispersing the complex of the present invention uniformly in the system, whereas the two-part hair cosmetic composition exhibits excellent effects. Cosmetics differ greatly in that complex-like products are formed non-uniformly directly on the hair. Further, in this two-part type hair cosmetic, simply mixing two parts, as in the case of the composite of the present invention, uses a combination of composites having different properties and uses a cosmetic in which it is blended. It is difficult to adjust gender.

The complex of the present invention having the above-mentioned properties can contribute to its multifunctionality and high functionality by blending it in a cosmetic. The form in which the cosmetic containing the composite of the present invention (hereinafter, also referred to as the present cosmetic) is not particularly limited, and hair cosmetics, face wash, lotion, milky lotion, cream, gel, Essences (cosmetics), packs, masks, and the like can also be used. In such cases, the cosmetics of the present invention significantly improve the smooth feeling and smooth feeling on hair or skin. It has the characteristic that it can be performed.

Further, if it is a makeup cosmetic, it can also take the form of a foundation, lipstick, etc., and in such a case, these cosmetics of the present invention can be applied to the skin as a cosmetic effect, such as adhesion to the skin, spreading, and stickiness. It has the characteristic that it can be significantly improved.

Further, the dosage form of the cosmetic of the present invention is also an aqueous solution, a solubilizing system, an emulsifying system, a powder system, an oil-liquid system, a gel system, an aerosol system, a water-oil two-layer system, a water-oil-powder 3 A wide range of dosage forms can be employed, including layered systems. Incidentally, in the cosmetic of the present invention, as long as the intended effect of the present invention is not impaired due to the incorporation of the composite of the present invention, it is possible to incorporate general components usually incorporated in the cosmetic. Of course.

That is, moisturizing agents, whitening agents, anti-inflammatory agents, ultraviolet protective agents, animal and plant extracts, vitamins, liquid fats and oils, solid fats and oils, waxes, hydrocarbon oils, higher fatty acids, higher alcohols, synthetic ester oils, silicones , A surfactant, a preservative, a chelating agent, a water-soluble polymer not involved in the composition of the composite of the present invention, a thickener, a powder component, a pigment, a fragrance, water, a lower alcohol, etc., if necessary. It can be appropriately compounded therein.

In view of the above-mentioned properties of the composite of the present invention, a typical embodiment of a form that can be used as the cosmetic is a hair cosmetic. Hereinafter, an embodiment of a hair cosmetic composition in which the composite of the present invention and a specific component are combined to make the most of the excellent properties of the composite of the present invention will be described. In the present invention, “cosmetics for hair” literally means any cosmetics used for hair, such as shampoos, hair rinses, hair treatments, hair conditioners, hair packs, etc., which can be subjected to a water rinsing step. means.

B. Embodiment of the cosmetic for hair comprising the complex of the present invention and an amphoteric surfactant and / or a nonionic surfactant [cosmetic for hair of the present invention (1)]: As described above, the present invention The composite can exhibit excellent properties in hair cosmetics, but if it is used alone, it is inferior in foaming power and detergency, and the intended cosmetic form (for example, hair cosmetics such as shampoo) Fees), it tends to be difficult to give the user sufficient satisfaction. Therefore, the present inventor has formulated an amphoteric surfactant and / or a nonionic surfactant in a hair cosmetic in addition to the above-described composite of the present invention, thereby making it possible to mix only the composite of the present invention. It has been found that the above-mentioned problems involved can be overcome.

The amphoteric surfactant which can be blended with the complex of the present invention in the hair cosmetic (1) of the present invention is not particularly limited as long as it is amphoteric surfactant which can be blended in a usual hair cosmetic. Not something. For example, 2-undecyl-

In the hair cosmetic composition (1) of the present invention, one or more of the above amphoteric surfactants and / or nonionic surfactants can be selected and blended. By this blending, the complex of the present invention can be stably dissolved in a system, for example, the complex of the present invention can be stably dissolved even at a low temperature.

The amount of the amphoteric surfactant in the hair cosmetic composition (1) of the present invention is not particularly limited, but is generally 0.1% by weight based on the total cosmetic composition. As described above, the content is 20% by weight or less, preferably 5.0% or less.
% By weight and 15% by weight or less.

The amount of the nonionic surfactant in the hair cosmetic composition (1) of the present invention is not particularly limited, but is generally 5 to the total cosmetic composition. It is from 0.0% by weight to 40% by weight, preferably from 8.0% by weight to 30% by weight.

When the amphoteric surfactant and the nonionic surfactant are combined and incorporated into the hair cosmetic composition (1) of the present invention, the total of both surfactants is 30 to the total cosmetic composition. It is preferable that the content be not more than weight%. For example,
When the nonionic surfactant is blended at 10% by weight of the cosmetic, the amphoteric surfactant is added at 10% by weight of the total cosmetic,
It is preferable to combine them in a ratio of 5% by weight or 20% by weight.

When these surfactants are added to the hair cosmetic composition (I) of the present invention in an amount exceeding the upper limit of the amount of the amphoteric surfactant and / or nonionic surfactant, the scalp may be irritated. Tends to be too strong, which is not preferable. Conversely, if the amount of the amphoteric surfactant and / or the nonionic surfactant is not more than 5.0% by weight of the total cosmetic, the intended effect of dissolving the complex stably in the system is obtained. Will be difficult to achieve.

The compounding amount of the composite of the present invention in the hair cosmetic of the present invention (1) is 0.5% by weight or more and 20% by weight or less of the total cosmetic, preferably 1.0% by weight. As described above, the content is 15% by weight or less.

If the compounding amount of the complex of the present invention is less than 0.5% by weight of the total cosmetics, a sufficient rinsing effect cannot be given to the cosmetics, which is not preferable. This is not preferable because the system tends to fail.

The method for producing the hair cosmetic (1) of the present invention containing these essential components is not particularly limited, but an essential component other than the composite of the present invention and optional components (described later) are desired. It is preferable to add the complex of the present invention prepared in the above-described step in advance to the system mixed in the form to prevent decomposition of the complex of the present invention by heating or the like as much as possible.
