DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lipstick, and more particularly to a lipstick which is excellent in make-up, has a good use feeling, and has a good finish.

[0002]

BACKGROUND OF THE INVENTION Conventional lipsticks have the disadvantage that after application to the skin, they have poor makeup and tend to adhere to clothes and cause bleeding. Various attempts have been made to correct these disadvantages. For example, after blending a volatile oil agent, after application, the oil agent volatilizes, leaving a coloring material and a wax on an applied surface, an attempt to improve cosmetic stickiness, a film forming agent such as a polymer in the volatile oil agent. Is blended, and this is
Attempts are made to form a polymer film on the skin surface by applying and drying it to improve the stickiness.

[0003] However, lipsticks using the above volatile oils lose gloss due to volatilization of the volatile oils over time,
There was a drawback that lipstick was thin.

[0004] Therefore, there has been a demand for the development of a lipstick which has a good feeling in use and finish and which has excellent makeup.

[0005]

Means for Solving the Problems The inventors of the present invention have made intensive studies in view of the above circumstances, and have found that a polyoxyalkylene-modified organosiloxane, a branched ester oil, a (semi) solid fat and a pigment are blended in specific ratios. As a result, the present inventors have found that a lipstick which has a good feeling in use and finish and which is excellent in make-up can be obtained, thereby completing the present invention.

That is, the present invention provides the following component (a):
(B), (c) and (d) (a) The following general formulas (1) to (4)

These polyoxyalkylene-modified organosiloxanes (1) to (4) are, for example, Nippon Unicar Co., Ltd., Shin-Etsu Chemical Co., Ltd., Dow Corning Toray Co., Ltd.
It is marketed by Silicone Co., Ltd. and Toshiba Silicone Co., Ltd.

Among these polyoxyalkylene-modified organosiloxanes, it is preferable that the polyoxyalkylene group contains 1 to 50% by weight (hereinafter, simply referred to as "%") in the molecule to obtain a good finished feeling and cosmetics. It is particularly preferable for obtaining a moist.

The component (a) may be used singly or as a mixture of two or more kinds. The compounding amount is 0.1 to 50%,
In particular, it is preferably 1 to 20%. If it is less than 0.1%, the effects such as long-lasting makeup are not sufficient.

Examples of the branched ester oil of component (b) used in the present invention include monoesters, diesters, and triesters having a branched portion in one or both of a fatty acid and an alcohol forming an ester. Can be

That is, as the branched ester oil, an ester comprising a monohydric alcohol having 3 or more carbon atoms and a monobasic acid of an aliphatic carboxylic acid having 3 or more carbon atoms and having a branch; a monohydric alcohol having 3 or more carbon atoms And a dibasic diester of an aliphatic carboxylic acid having 3 or more carbon atoms, and a branched diester having a branch, a dihydric alcohol having 3 or more carbon atoms and a monobasic acid of an aliphatic carboxylic acid having 3 or more carbon atoms, and Branched diester having a branch; a branched triester composed of a monohydric alcohol having 3 or more carbon atoms and a tribasic acid of an aliphatic carboxylic acid having 3 or more carbon atoms and having a branch, and having 3 carbon atoms
The branched triester which comprises the above trihydric alcohol and the monobasic acid of the aliphatic carboxylic acid having 3 or more carbon atoms and has a branch is exemplified.

Specific examples of such a branched ester oil include:
Monoesters such as isotridecyl isononanoate, isostearyl myristate, isostearyl isopalmitate and isopropyl isostearate; diesters such as neopentyl glycol dicaprate; triesters such as trimethylolpropane triisostearate. Among them, those which are liquid at room temperature and have a relative dielectric constant of 2.0 to 4.5, especially 2.5 to 4.
0 is preferred.

The component (b) may be used singly or as a mixture of two or more. The compounding amount is preferably 1 to 90%, particularly preferably 5 to 70%. If it is less than 1%, the feel is poor, while if it exceeds 90%, the effects such as long-lasting makeup are not sufficient, and both are not preferred.

The semi-solid fat or solid fat of the component (c) used in the present invention includes, for example, mokuro, hardened tallow, carnauba wax, candelilla wax, rice wax, beeswax, ceresin wax, microcrystalline wax, paraffin Wax, polyethylene wax, hardened jojoba oil, lanolin, petrolatum, and the like.

The compounding amount of the component (c) is 1 to 7 in the total amount of the lipstick.
0%, preferably 5 to 50%.

The pigment of the component (d) used in the present invention includes known pigments usually used in cosmetics such as talc, sericite, mica, kaolin, silica, nylon powder, polyethylene powder, cellulose powder and the like. Extender; coloring agents such as carbon black, titanium oxide, iron oxide, zinc oxide, ultramarine, navy blue, chromium oxide, organic tar pigments and lakes; and composite pigments such as titanium mica and iron oxide coated mica. In addition, these cosmetic pigments can be used as silicones, higher fatty acids, higher alcohols,
Those treated with a fatty acid ester, metal soap, amino acid or alkyl phosphate can also be used.

The amount of component (d) is from 1 to 90%, preferably from 5 to 50%, based on the total amount of the lipstick of the present invention.

In the lipstick of the present invention, in addition to the above-mentioned components, depending on the purpose, unless otherwise impairing the effects of the present invention, other oil-based raw materials substantially free of water, surfactants, medicinal ingredients, Preservatives, antioxidants, humectants, intercellular lipids (such as ceramide), ultraviolet absorbers, fragrances and the like can be added.

The lipstick of the present invention can be produced by heating, mixing, stirring, etc. the above components in a conventional manner.
