Description

SPECIFICATION Hair coloring composition Hair color preparations are generally classified, according to the durability of the color imparted to the hair, into temporary, semipermanent and permanent preparations.

This invention relates to temporary hair coloring compositions usually called hair colors and more particularly to hair coloring compositions for temporarily toning hair or coloring gray hair for cosmetic purposes.

Temporary toning is a cosmetic means for altering the appearance or look by coloring part of the whole of hair to a brighter or more vivid color. And cosmetic coloration of gray hair is intended to give a uniform tone by darkening gray hair or lightening black hair to subdue gray in mixed gray hair in an attempt to alterthe appearance.

Generally known are hair coloring products of the temporary type for cosmetic use which are filled into an aerosol spray having a pressurized container. These hair color products comprise a binder such as polyvinylpyrrolidone, an alkanolamine solution of polyacrylate or polymethacrylate; a solvent such as ethanol; a propellant such as Freon; and a coloring agent containing an inorganic pigment having a hiding power, e.g., mica, titanium oxide-treated or -coated mica (hereinafter referred to as titanium mica), iron oxide-treated titanium mica, titanium oxide, aliminum powder, copper powder or iron oxide, an organic pigment, and/or a dye.These conventional temporary hair coloring products, applied to hair, cause hair fibers to adhere to each other due to the resin present therein as a binder, whereby the hair gives a harsh feel after drying and likely to come out by brushing and combing. Although a lower resin content slightly reduces the harsh feeling, another problem is presented that the coloring agent given to the hair is prone to rub off on contact with clothes and hands, thereby staining the clothes and hands. Further, when using an organic pigment or a dye as a coloring agent, the coloring agent on contact with clothes penetrates fibers in the clothes and can not wash out in laundry.

If an inorganic pigment with a good hiding power is singly used as a coloring agent, phase separation and caking are apt to occur in the spray container due to its high specific gravity, and even in use of a container with a stirring ball, shaking of the container must be repeated tens of times to redispersethe components.

Also available are temporary hair coloring products which comprise the same components, i.e., coloring agent, binder and solvent, as in aerosol dispensers, placed in a container and which are applied to hair with a brush or the like. However, these products also have the same drawbacks as aerosol products.

Temporary hair coloring products in the form of cream are known which incorporates an inorganic pigment of good hiding power kneaded into petrolatum or like oil of low fluidity and high viscosity. These products are clammy, tend to easily adhere to hands or the like and can not produce a natural effect in appearance nor can make the hair satisfactorily attractive.

An object of the present invention is to provide temporary hair coloring compositions which are capable of giving a natural appearance and feeling after application.

Another object of the invention is to provide temporary hair coloring compositions which can not easily rub off even by contact with clothes, hands and the like.

A further object of the invention is to provide temporary coloring compositions which can easily wash out in laundry if deposited on clothes and the like.

An additional object of the invention is to provide temporary hair coloring compositions which are less susceptible to caking and which can be easily redispersed by shaking the spray container several times on occurrence of phase separation.

Other objects and features of the present invention will become apparent from the following description.

This invention provides hair coloring compositions comprising 100 parts by weight of colored mica, 20 to 100 parts by weight of silicone oil having a kinematic viscosity of 10 to 50 cSt (centisokes) at 200C and 350 to 3000 parts by weight of a solvent (hereinafter referred to as first compositions of the present invention).

This invention also provides hair coloring compositions comprising 100 parts by weight of colored mica, 20 to 100 parts by weight of silicone oil having a kinematic viscosity of 10 to 50 cSt at 20"C, 100 to 2000 parts by weight of a solvent and 100 to 10000 parts by weight of a propellant (hereinafter referred to as second compositions of the present invention).

This invention further provides hair coloring compositions comprising 100 parts by weight of a coloring agent consisting of 20 to 70% by weight of colored mica and 80 to 30% by weight of iron oxide powder, 40 to 160 parts by weight of silicone oil having a kinematic viscosity of 10 to 50 cSt at 20"C and 300 to 5000 parts by weight of a solvent (hereinafter referred to as third compositions of the present invention).

This invention also provides hair coloring compositions comprising 100 parts by weight of a coloring agent consisting of 20 to 70% by weight of colored mica and 80 to 30% by weight of iron oxide powder, 40 to 160 parts by weight of silicone oil having a kinematic viscosity of 10 to 50 cSt at 20"C, 100 to 3000 parts by weight of a solvent and 100 to 10000 parts by weight of a propellant (hereinafter referred to as fourth compositions of the present invention).

My research has revealed that hair coloring compositions incorporating colored mica or a mixture of colored mica and powdery iron oxide as a coloring agent and silicone oil having a specific kinematic viscosity can considerably moderate or substantially overcome the foregoing problems of conventional hair coloring products. It has been also discovered that these hair coloring compositions further containing a propellant can exhibit outstanding properties. Based on these novel findings, the present invention has been accomplished.

The first to fourth hair coloring compositions of the present invention will be described below in detail.

1. First composition of the present invention (i) Examples of colored micas which can be used in the present invention are titanium micra, iron oxide-treated titanium mica, chromium oxide-treated titanium mica, Prussian blue-treated titanium mica and the like. These compounds can be used singly or at least two of them are usable in mixture. Useful coloured mica is in the form of a sheetlike crystal having a maximum diameter of up to about 5 to about 60 ijm and a thickness of about 0.1 m. Titanium mica has a layer of titanium dioxide formed over the surface of thin flake-like mica crystal as a substrate and having the thickness of layer controlled in a limited range.Such mica, although white in appearance, is capable of forming an interference color such as yellow, red, blue or green color and achieves particularly remarkable color formation with a black background, e.g. black hair.

Iron oxide-treated titanium mica has a layer or layers of titanium dioxide and tri-iron tetraoxide, and/or iron sesquioxide and can produce lustrous, bright yellow to brown color, depending on the thickness of the layers. Chromium oxide-treated or Prussian blue-treated titanium mica is obtained by coating titanium mica with chromium oxide or Prussian blue (iron ferrocyanide and iron ferricyanide). Of these colored micas, commercially available are, for example, titanium micas under the trademarks "Timiron" and "Soloron", and iron oxide-treated, chromium oxide-treated and Prussian blue-treated titanium micas under the trademark "Coloron", produced by E. Merck Co., West Germany.

The foregoing colored micas with the surface treated to give a lipophilic property can be redispersed in a coloring composition in a higher degree. Known methods for surface-treating colored mica to provide a lipophilic property include a method comprising coating colored mica with a mixture of hydrocarbon, higher fatty acid and silicone oil, followed by baking the coating mica (Japanese Unexamined Patent Publication No. 2951211981) and a method comprising coating colored mica with silicone oil and baking the coated mica.

(ii) Silicone oils useful in the present invention are those having a kinematic viscosity of 10 to 50 cSt at 20"C. Examples of suitable silicone oils are dimethylpolysiloxane, methylphenylpolysiloxane, etc. More preferred silicone oils are those having a kinematic viscosity of 15 to 30 cSt at 200C.

(iii) Example of solvents useful in the present invention are ethanol and isopropyl alcohol. Alcohols usable as a solvent may contain up to 40% by weight of water. If more than 40% by weight of water is present, it takes a prolonged period of time to dry the hair after application of the composition, and the composition can not be uniformly sprayed because the silicone oil tends to be separated and suspended in the upper portion of the composition when the composition is introduced into a non-gas spray.

(iv) The first composition of the present invention comprises usually 100 parts by weight of the colored mica, 20 to 100 parts by weight of the silicone oil and 350 to 3000 parts by weight of the solvent, preferably 100 parts by weight of the colored mica, 30 to 70 parts by weight of the silicone oil and 500 to 1500 parts by weight of the solvent. With less than 20 parts by weight of the silicone oil per 100 parts by weight of the colored mica, the composition after application is readily removed by brushing and can not spread to a satisfactory extent by brushing, thereby likely giving a harsh feel to the hand. Above 100 parts by weight of the silicone oil, the hair provided with the composition feels clammy and weighty, and may soil the hand in touch therewith.Below 350 parts by weight of the solvent per 100 parts by weight of the coloring agent, the compostion can not be uniformly sprayed due to its high concentration and tends to plug up in the valve.

Above 3000 parts by weight of the solvent, a reduced coloring effect results because of the low concentration.

II. Second composition of the present invention The second composition of the present invention contains a propellant such as Freon and liquefied petroleum gas commonly used as a gas in aerosol sprays, in conjunction with the same components, colored mica, silicone oil and solvent, as in the first composition of the present invention.

The second composition comprises usually 100 parts by weight of the colored mica, 20 to 100 parts by weight of the silicone oil, 100 to 2000 parts by weight of the solvent and 100 to 10000 parts by weight of the propellant, preferably 100 parts by weight of the colored mica, 30 to 70 parts by weight of the silicone oil, 300 to 1000 parts by weight of the solvent and 1000 to 5000 parts by weight of the propellant.

It is preferred to reduce the amount of the solvent with an increase in the amount of the propellant in the second composition.

111. Third composition ofthepresentinvention (i) The third composition of the present invention contains a coloring agent consisting of 20 to 70% by weight of the same colored mica as in the first composition and 80 to 30% by weight of iron oxide powder, preferably 30 to 60% by weight of the colored mica and 70 to 40% by weight of the iron oxide powder.

Examples of useful iron oxide powder are those usualy used as a pigment, e.g., with cubical structure about 0.1 to about 2.0 lim in diameter and needle-like structure about 0.01 to about 1.0 Am in width and about 0.1 to about 2.0 lim in length. iron oxides used as a pigement include those having various colors such as black, pale yellow to yellowish brown, pale red to reddish brown, and the like. According to the present invention, all kinds of these iron oxides can be used and are usable singly or in mixture as required. They are commercially available and sold, for example, under the trademarks "MAPICO yellow LL-XLO", "MAPICO Red R-516-L" and "MAPICO Black BL-100" by Titan Kogyo Kabushiki Kaisha, Japan.

(ii) The third composition comprises usually 100 parts by weight of a coloring agent consisting of 20 to 70% by weight of the colored mica and 80 to 30% by weight of the iron oxide powder, 40 to 160 parts by weight of the silicone oil and 300 to 5000 parts by weight of the solvent, preferably 100 parts by weight of the coloring agent, 60 to 100 parts by weight of the silicone oil and 1000 to 2000 parts by weight of the solvent.

When applied to hair, a composition containing a greater proportion of oxide powder outside the range of the mica-iron oxide mixture, the hair lacks such luster as that of healthy hair and has an unnatural appearance.

The third composition incorporates a greater amount of silicone oil than the first composition because of the presence of iron oxide powder high in bulk density.

IV. Fourth composition of the present invention The fourth composition includes a propellant such as Freon and liquefied petroleum gas, in addition to the same components, i.e., coloring agent, silicone oil and solvent as in the third composition.

The fourth composition comprises 100 parts by weight of a coloring agent consisting of 20 to 70% by weight of the colored mica and 80 to 30% by weight of the iron oxide powder, 40 to 160 parts by weight of the silicone oil, 100 to 3000 parts by weight of the solvent and 100 and 10000 parts by weight of the propellant, preferably 100 parts by weight of the coloring agent, 60 to 100 parts by weight of the silicone oil, 500 to 1500 parts by weight of the solvent and 1000 to 5000 parts by weight of the propellant.

It is preferred also in the fourth composition to reduce the amount of the solvent with an increase in the amount of the propellant.

Additives such as perfume, moisturizing agent, binder, oil and vegetable extract which are used commonly in the manufacture of hair coloring preparations can be incorporated in the compositions of the present invention, insomuch as the inclusion of the additive does not impairthe outstanding properties of the present compositions. Examples of useful moisturizing agents are propylene glycol, 1,3 butylene glycol, sodium dl-pyrrolidone carboxylate and the like. Examples of useful binders are polyvinylpyrrolidone, vinylpyrrolidone-vinyl acetate copolymer, methyl acetate-maleic anhydride copolymer, alkanolamine solution of acrylic resin, methacrylic acid derivative copolymer, vinylpyrrolidone-dimethyl aminoethyl methacrylate copolymer, and the like.Examples of useful vegetables extracts are a lily extract, aloe extract and the like. Examples of useful oils are hydrocarbons such as liquid paraffin and petrolatum, esters such as isopropyl myristate, lanolin and its derivatives, polyethylene glycol and its derivatives, polypropylene glycol and its derivatives, and the like.

Hair coloring compositions of the present invention can achieve the following remarkable results.

(1) After the application of the composition, the hair, even when dried, remains free of abnormal harshness, and brushing and combing can be smoothly accomplished.

(2) The composition imparts a natural, lustrous and attractive shade to hair.

(3) The composition, even when deposited on clothes, does not penetrate fibers in the clothes and thus can relatively easily wash out in laundry.

(4) When deposited on human skin, the composition does not give a clammy feel and can be easily removed.

(5) A variety of shades can be produced by varying the proportions of colored mica and iron oxide powder or mixing two or more kinds of colored micas and particulate iron oxides.

(6) The composition as used in a spray is kept from caking and can be easily redispersed by shaking the spray container several times if the solids in the composition should have settled in the container.

(7) The composition imparted to hair is easily removable with a shampoo, thereby enabling the hair to regain the original color.

Given below are Examples and Comparison Examples to clarify the features of the present invention.

In the following Examples and Comparison Examples, compositions were prepared by placing the components (total amount of 100 g calculated as 100 parts by weight) into a beaker, stirring the components to obtain a uniform dispersion, and passing the dispersion through a 100 mesh screen (mesh size=1491JLm).

Example 1 Six kinds of hair coloring compositions (samples 1-1 to 1-6) were prepared by using the components as shown below in Table 1, and each sample was filled into a non-gas spray dispenser (capacity of 50 ml) capable of spaying about 0.1 g of aerosol at a time. The spray container was shaken several times before use to give a homogeneous dispersion, and then the sample was uniformly sprayed over a black human short hair wig (having an amount of about 100 g) 40 times. Then the hair was brushed about 50 times. Table 2 below shows the results.

Merck Co., West Germany The composition thus pepared was charged into the same non-gas spray as used in Example 1 and was shaken 4 or 5 times. The the composition was uniformly sprayed 50 times over the whole of slightly waved female hair (with a normal amount of hair) except for the front part of the hair. The whole hair including the front part was brushed about 80 times and was uniformly colored yellowish brown.

The composition was not flaked by brushing.

The brushed hair permitted smooth combing, and was free of an oily feeling, and the hand on touch with the hair was left unsoiled.

The hair regained the original color after a single shampoo.

Example 6 A hair coloring composition was produced in the same manner as in Example 5 with the exception of using 80% ethanol.

The composition involved a slightly prolonged drying, but emitted less alcoholoc odor, which increased ease of use. The composition exhibited the other characteristicSt which were comparable with those of the composition prepared in Example 5.

Example 7 A hair coloring composition was produced from the components as indicated below in Table 10, and then 30 g of the composition was fed, along with 70 g of a propellant (the same as used in Example 4), into an aerosol spray.

The composition thus prepared was sprayed over part of female straight black hair (having a normal amount) and only the part thus sprayed was colored brightly blue.

No coloring agent came off by brushing. The hair was smoothly combed, stained no hand and presented no oily feeling.

Brushing about 20 times turned the whole hair uniformly lustrous gray. No composition was flaked by brushing and the colored mica deposited on the skin of head was easily removed with soft paper.

The brushed hair was free from an oily feeling and smeared no hand.

Example 9 A hair coloring composition was prepared from the components as listed hereinafter in Table 12 and was filled into a non-gas spray capable of spraying about 0.08 g of aerosol at a time.

The spray was shaken 4 or 5 times before use and uniformly applied 60 times over the whole area of a female hair (about 20% gray hair).

After drying, the hair was brushed 100 times, whereby the colored mica was evenly distributed throughout the hair but was not flaked.

The hair was colored wine red and the gray hair was scarcely seen at a distance of over about 2 m. The composition was comparable in the other characterisitcs with those of the samples obtained in the above Examples.
