Description

Detailed Description of the Invention The present invention has good adhesion to lips etc. (does not twist or move), abrasion resistance (does not stick to fingers, etc.), bending strength,
A water-in-oil type emulsion stick cosmetic (hereinafter referred to as W for convenience) that has excellent water retention, spreadability when applied to the skin, and moldability (mold release).
/O-type stick cosmetics).

Conventionally, emulsified stick cosmetics have been produced by mixing a gel consisting of a surfactant, glycerin, mannitol, fructose, etc. with a base material mainly consisting of oily ingredients, and then mixing it with water. However, adhesion to the lips, abrasion resistance, elongation during application, releasability during molding, etc. are unfavorable and are still unsatisfactory.

As a result of intensive research aimed at improving these drawbacks, the present inventors have found that a water-in-oil type (W/O type) stick cosmetic with the configuration described below has a butter-like feel and does not cause resistance to the lips. In addition to the advantages of imparting emolient properties to the skin, making it possible to add water-soluble active ingredients and natural pigments, etc., it also has advantages such as adhesion to lips, etc., abrasion resistance, spreadability when applied, and moldability when molding. The present invention has been completed based on the discovery that the present invention is extremely superior to the above.

The objectives of the present invention are to have good adhesion to lips, etc. (no wobbling or wobbling), abrasion resistance (hard to stick to hands and fingers), bending strength, water retention, elongation when applied to the skin, and chicks when molded. To provide a water-in-oil type stick cosmetic with outstanding moldability. That is, the present invention is a water-in-oil type emulsified stick cosmetic prepared by adding and mixing an aqueous maltitol solution to a mixture of diglycerol oleic acid ester and an oily substance or pigment, and emulsifying the mixture. As the diglycerol oleate contained in the present invention, diglyceryl monooleate and diglyceryl dioleate are preferable.

They may be used alone or in combination. Its content is 0.1 to 10% by weight, preferably 1 to 5% by weight, based on the weight of the composition. If it is less than 0.1% by weight, stability, water resistance, and mold release properties during molding will decrease, and if it is more than 5% by weight, bending strength, adhesion to lips, etc., and abrasion resistance will tend to decrease. .

The oily substance is a general term for the oily substances of known stick cosmetics, and includes oils and fats, waxes, liquid hydrocarbons, ester oils, higher fatty acids, and the like. Examples of oils and fats include castor oil, olive oil, avocado oil, balm oil, and cacao oil; examples of waxes include shark wax, wood wax, lanolin,
Millow, paraffin wax, carnauba wax, candelilla wax, etc. Liquid hydrocarbons include vetrolatum, liquid paraffin, ceresin, microcrystalline wax, squalane, etc. Higher alcohols include myristyl alcohol, cetyl alcohol, stearyl alcohol, oleyl, etc. Examples of ester oils such as alcohol and lanolin alcohol include butyl stearate, octyldodecyl myristate, and isof myristate. Higher fatty acids include lopyl ester, lanolin fatty acid isopropyl ester, stearate butyl ester, lauric acid hexyl ester, oleic acid oleyl ester, adipate diisopropyl ester, sebacate diisopropyl ester, etc.
Examples include, but are not limited to, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, behenic acid, and lanolin fatty acids. Oils and fats, liquid hydrocarbons, higher fatty acids, commonly used in cosmetics,
Higher alcohols, waxes, ester oil, etc. can be used as appropriate. These oily substances may be used alone or in appropriate combinations.

Its content is from 30 to 9% by weight, preferably from 50 to 7% by weight, based on the weight of the composition. If it is less than 30% by weight, stability will decrease, and if it is more than 9% by weight, the above-mentioned effects will tend to decrease.

Organic pigments, inorganic pigments, and dyes are used as pigments, but in particular in the present invention, since they contain a relatively large amount of water, a wide range of new dyes such as natural pigments and food colors can be effectively and appropriately selected and used. It is also extremely easy to adjust the hue. still,
Water-soluble dyes and the like may be added after being dissolved in a maltitol aqueous solution described below. When mixing maltitol, it is preferable to use it as an aqueous solution. The content of maltitol is 1 to 25% by weight, preferably 3% by weight based on the total amount of the composition.
~15% by weight. If it is less than 1% by weight, stability, water retention, bending strength, elongation when applied to the skin, moldability during molding, adhesion to lips, and mold release during molding will decrease, and from 25% by weight If the amount increases, water resistance, adhesion to lips, etc., and abrasion resistance tend to deteriorate.

Water is added as a maltitol aqueous solution, and the amount used is 1 to 50% by weight, preferably 5% by weight based on the weight of the cosmetic.
~2% by weight. If it is less than 1% by weight, the adhesion to the lips, elongation when applied to the lips, moldability during molding, etc. tend to deteriorate, and if it exceeds 50% by weight, stability, etc. tend to deteriorate.

The W/O type stick cosmetic of the present invention can be produced by various methods, but one method is to add a mixture of a required amount of the diglycerol oleate and an oily substance or a pigment, This is done by adding and mixing an aqueous maltitol solution under a rope. In this case, a water-soluble dye and a water bathing agent (active ingredient) may be added to and mixed with the maltitol aqueous solution. If necessary, polyvalent metal ion sequestrants, known cosmetic UV inhibitors, preservatives, etc. may be mixed with the mixture of diglycerol oleate and oil-based substances or pigments, or with the maltitol aqueous solution. It's okay. The liquid temperature when mixing Hinaazusa is not particularly limited, but is preferably 60 to 95 oo, most preferably 7
The temperature is 0 to 85°C.

If the temperature during mixing is too low, uniformly dispersed waxes may precipitate, or coarse oil particles may be easily liberated in parts, and if the temperature is too high, the components may easily decompose or change in quality. There is. After mixing, emulsifying, and dispersing, the mixture is gradually cooled to room temperature. Incidentally, it is preferable to add fragrances, drugs that are unstable at high temperatures, etc. during this cooling process. The W/O type Sticky Q material of the present invention, which has been cooled and taken out from a mixer such as a kneader, may be placed in a suitable container for I○ material (
When applying to the lips with butt hair), or it may be placed in a molding device and molded by a conventional method. The W/O type stick quill board of the present invention has extremely good mold releasability during molding due to the coexistence effect of maltitol and diglycerol oleate. One of the features of the present invention is that it is significantly superior to the case where a gel is added and mixed, and no defective molding products are observed. The W/O type STICK-Q snake oil of the present invention forms a water-in-oil type homogeneous and stable emulsion, and it has a butter-like feel and can be applied to the lips without any resistance, leaving an emulsion on the lips. It also makes it possible to easily add water-soluble active ingredient drugs and non-toxic bright natural pigments.

In addition, it has excellent adhesion to lips, abrasion resistance, elongation during use, and moldability during molding (for example, compared to when sorbitol-glycerol oleate gel is added and mixed). In its industrial production, there is no need to prepare the gel at all, and it can be easily prepared by a normal mixing method, and it can be easily modeled during molding, resulting in defective molded products. However, its commercial value and industrial significance are extremely large. Such useful and remarkable effects are due to the combined use of maltitol and diglycerol oleate and the mixing means, and will become clearer from the Examples described below. Examples of the present invention will be described below.
