Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention has a smooth spread, an excellent moisturizing effect on the lips, and a good dispersibility of coloring pigments and dyes. It relates to an excellent lipstick composition.

[0002]

2. Description of the Related Art Attempts have been made for a long time to mix lipstick with water to obtain a moisturizing effect on the lips and a refreshing feeling. For example, Japanese Patent No. 1125122, Japanese Patent Laid-Open No. 53-127841,
JP-A-54-49337 and JP-A-56-45045 disclose emulsion lipsticks.

These are water-in-oil type in which water is added together with a surfactant and a polyhydric alcohol (hereinafter referred to as "W / O type").
It is an emulsified lipstick that has a good feel due to the blended water, has a high moisturizing property, and has good stability over time against sweating and dusting (the oil and wax in the components deposit on the surface over time). , The blended water gradually volatilizes during storage over time, resulting in skin thinning and falling out of the container, significant loss of surface gloss, and pigment transfer from the oil phase to the water phase or from the water phase to the oil phase. This often caused a change in color tone.

On the other hand, attempts have been made to improve such instability due to the inclusion of water. That is, in Japanese Examined Patent Publication No. 62-61565 and Japanese Examined Patent Publication No. 3-76284, by using a considerable amount of a special surfactant or fixing water between the layers of the water-swelling clay mineral, the dispersion stability of the pigment and the aging can be improved. Ingenuity has been devised to improve the stability of color tone.

However, these are all related to the stability of the lipstick itself as a preparation, and satisfactory coloring properties and color retention when the lipstick is applied to the lips have not been obtained sufficiently.

[0006]

One method for improving the color retention when applied to the lips is to compound a dye or to use a coloring pigment having a high dyeing property. In general, emulsified lipstick has a high moisturizing effect,
Although it has excellent usability, the dye or pigment is oriented in the aqueous phase due to the influence of the surfactant used, or the dye or pigment is adsorbed by the surfactant or other raw material components used for blending water. When applied to the lips, the color development and color retention are usually poor.

As a result of intensive studies to solve the problems of the prior art, the present inventors have found that water-swelling clay minerals are mixed with quaternary ammonium salt type cationic surfactants and complex lipids or non-lipids. A W / O type emulsion obtained by mixing an oil component and an aqueous phase component by using an organically modified clay mineral obtained by treatment with an ionic surfactant as an emulsifier emulsifies many aqueous phase components even if the emulsifier is in a relatively small amount. In addition, the lipstick containing this W / O emulsion has a smooth spread and is excellent in moisturizing the lips.
While having the characteristics as an emulsified lipstick, they were also found to have excellent dispersibility of color pigments and dyes, color development when applied to the lips, and excellent color retention effect, and completed the present invention. .

[0008]

Means for Solving the Problems That is, the present invention provides an organically modified clay obtained by treating a water-swellable clay mineral with a quaternary ammonium salt type cationic surfactant and a complex lipid or a nonionic surfactant. A lipstick composition comprising a W / O emulsion containing a mineral, an oil, and an aqueous phase component.

The content of the quaternary ammonium salt type cationic surfactant is 60 based on 100 g of the water-swelling clay mineral.
It is preferably about 140 meq. The content of the complex lipid is 1 to 3 with respect to 100 g of the water-swelling clay mineral.
The content of the nonionic surfactant is preferably 5 to 200 with respect to 100 g of the water-swelling clay mineral.
It is preferably g. Further, the amount of the W / O emulsion blended is preferably 0.5 to 50% by weight based on the total weight of the lipstick composition.

A W / O type emulsion comprising a water-swellable clay mineral treated with a quaternary ammonium salt type cationic surfactant and a nonionic sea surface active agent is applied to a hand cream as a stable emulsified composition. About what to do

(Note 1) The HLB value of the nonionic activator is calculated by the following Kawakami's equation. (Here, Mw represents the molecular weight of the hydrophilic group and Mo represents the molecular weight of the lipophilic group.)

The organically modified clay mineral used in the present invention is, for example, a water-swellable clay mineral, a quaternary ammonium salt type cationic surfactant, a complex lipid (or a non-soluble lipid) in a low boiling point solvent such as water, acetone, or a lower alcohol. Ionic surfactant) is dispersed and stirred, or a water-swellable clay mineral and a quaternary ammonium salt type cationic surfactant are previously treated in a low boiling point solvent to obtain a cation-modified clay mineral. It is obtained by treating with a complex lipid (or a nonionic surfactant) and then removing the low boiling solvent.

Here, the water-swellable clay mineral and the quaternary ammonium salt type cationic surfactant are pretreated commercial products (manufactured by US National Red Co., Ltd.) as long as they are within the range specified by the present invention. It is also possible to use Benton-38 etc.).

Since the quaternary ammonium salt type cationic surfactant and the complex lipid (or nonionic surfactant) are intercalated between layers, the water-swelling clay mineral has a widened layer interval, so that X-ray Whether or not the quaternary ammonium salt type cationic surfactant and the complex lipid (or nonionic surfactant) are adsorbed can be confirmed by measuring the long plane spacing by diffraction.

If the obtained organically modified clay mineral is subjected to Soxhlet extraction with chloroform, ether or the like, the adsorbed substances between the layers will be washed away, so that the extract is subjected to gas chromatography analysis, thermal decomposition temperature measurement or thermal decomposition. The presence of the adsorbed substance can be confirmed by measuring the amount of decomposition (DTA-TG measurement) or the like.

The content of the quaternary ammonium salt type cationic surfactant in the organically modified clay mineral used in the W / O type emulsion constituting the lipstick composition of the present invention is 100 g of the water-swellable clay mineral. It is preferably 50 to 140 milliequivalents (hereinafter abbreviated as meg).

The content of the complex lipid in the organically modified clay mineral is 1 to 300 with respect to 100 g of the water-swellable clay mineral.
g is preferable, and more preferably 5 to 200 g.

The content of the nonionic surfactant in the organically modified clay mineral is preferably 5 to 200 g, more preferably 15 g, per 100 g of the water-swelling clay mineral.
~ 170g.

In the present invention, an organically modified clay mineral is dispersed in an oily lipstick base consisting of wax, oil, dye and / or pigment, and an aqueous phase component is added to and dispersed in the lipstick base to prepare a lipstick base. An excellent lipstick composition can be obtained by directly preparing a W / O type emulsion.

However, a W / O type emulsion is prepared in advance from the organically modified clay mineral, a part of the oil component in the lipstick base, and the water phase component, and this is added to the oily lipstick base to obtain the desired composition. Obtaining a lipstick composition is useful in that it avoids direct contact of the dyes and pigments with the aqueous phase components, and is a convenient way to make a large number of lipsticks of different shades.

When the W / O type emulsion is prepared in advance, the compounding amount of the organically modified clay mineral is about 0.25 to 5% by weight when the W / O type emulsion is set to 100, and in particular, 0. 5 to 3% by weight is preferable. The amount of the water phase component to be blended is about 10 to 90% by weight, and particularly 30
-80 wt% is preferred.

The amount of the W / O type emulsion thus obtained added to the lipstick base is preferably 0.5 to 50% by weight, more preferably 1 to 50% by weight based on the total weight of the lipstick. It is 30% by weight. If it is 0.5% by weight or less, the effect of blending the water phase component is not felt, and if it is 50% by weight or more, the moldability of the lipstick is deteriorated, which adversely affects the physical properties of the lipstick.

The wax, oil, dye and / or pigment used in the present invention may be any of those generally used in cosmetics, and examples thereof include the following.

That is, as wax and oil, beef tallow, squalane, olive oil, evening primrose oil, rice bran oil,
Animal and vegetable oils such as candelilla wax and carnauba wax, hydrocarbons, ester oils such as isopropyl myristate, pentaerythritol-tetra-2-ethylhexanoate,
Silicone oils such as methylphenyl silicone and dimethyl silicone, alcohols such as 2-octyldodecanol, 2-decyltetradecanol, stearyl alcohol, oleyl alcohol and cetyl alcohol, behenic acid, oleic acid, stearic acid, isostearic acid, hydroxystearin. Fatty acids such as acids are included.

As dyes and coloring pigments, in addition to legal pigments that are approved for use in lipsticks, titanium dioxide, red iron oxide, yellow iron oxide, black iron oxide and the like, and other pigments such as talc, mica, kaolin, Inorganic pigments such as calcium carbonate, barium sulfate, chromium hydroxide, titanium coated mica and bismuth oxychloride, and organic pigments such as crystalline cellulose, nylon powder, polyethylene powder and the like can be mentioned.

It is also possible to use those dyes, coloring pigments and other pigments which have been hydrophobized, and as the hydrophobizing agent, dextrin fatty acid esters, metal soaps, silicone compounds, fluorine compounds are used. Compound,
Examples thereof include organic compounds such as dibenzylidene sorbitol. A conventionally known method may be used as a method for carrying out the hydrophobic treatment using these hydrophobic treatment agents. For example, JP-A-6
