Abstract

PROBLEM TO BE SOLVED: To obtain a solid composition for a lipstick, excellent in not only characteristics of basically required usability, such as spread in coating smoothness and luster, but also appearance (surface state). SOLUTION: This composition for a lipstick contains 2.0-40.0 wt.% nonpolar wax and/or a waxy material, having 0-0.1 IOB, such as a micro crystalline wax, ceresin or a polyethylene wax, based on the total amount of the composition, and 0.5-10.0 wt.% silicon dioxide powder based on the total amount of the composition.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lipstick composition, and more particularly to a lipstick composition having an excellent surface condition when filled in a medium dish or jar type container.

[0002]

2. Description of the Related Art In general, lipstick compositions are compounded with powders such as wax, various oils, coloring agents, and fragrances.
The properties such as spreadability, smoothness, and gloss during application, which are basically required usability, and beauty of appearance (surface state) are maintained. When a non-polar wax was used as the wax, scale-like stripes were generated on the surface, and a good appearance was not obtained. Therefore, polar waxes (IOB = 0.065 to 0.151) such as carnauba wax and candelilla wax are used,
These waxes have been used in combination with other oils commonly used in lipsticks.

[0003]

However, when the composition for lipstick is molded into a medium dish or the like, the use of a polar wax such as carnauba wax or candelilla wax has the disadvantage that the perspiration stability becomes extremely poor. there were. Therefore, it has been desired to develop a technique that does not use a polar wax such as carnauba wax or candelilla wax and has a good surface condition. Accordingly, an object of the present invention is to provide a lipstick composition excellent in appearance (surface state) without impairing other usability.

[0004]

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve this problem, and as a result, when a specific amount of silicon dioxide powder is used, a lipstick composition having a good appearance without using a polar wax. I found that I could get something.

[0005] That is, the present invention is a lipstick composition comprising the following components (a) and (b) and having a solid property. (A) 2.0 to 40.0% by weight of a nonpolar wax and / or waxy substance having an IOB of 0 to 0.1 based on the whole composition; .
0% by weight

Hereinafter, the present invention will be described in detail. (Component (a)) The wax and / or wax-like substance that can be blended in the lipstick composition of the present invention is IOB = 0 to 0 among the waxes and / or wax-like substances usually blended in the lipstick composition. .1 substances. IO
When a wax having a B of more than 0.1 is used, the perspiration stability becomes poor. Here, the IOB is an inorganic value / organic value according to the organic conceptual diagram of Atsushi Fujita (Atsushi Fujita, Masami Akatsuka, Systematic organic qualitative analysis (mixture edition) 1974, published by Kyoritsu Shuppan), / Organic value = ratio line = IOB
(Inorganic Organic Balance) = tan α, which indicates the polarity of the organic compound. The higher the value, the higher the polarity and the water is ∞.

[0007] Examples of the wax having an IOB of 0 to 0.1 include mineral waxes such as polyethylene wax, paraffin wax, silicone wax, ceresin, and microcrystalline wax. These waxes and / or waxy substances can be used alone or in combination of two or more. Among these waxes and / or waxes, microcrystalline wax, ceresin or polyethylene wax is particularly preferable because of its excellent fit when used when blended.

The amount of the non-polar wax and / or wax-like substance in the lipstick composition of the present invention is 2.0 to 40.0% by weight, preferably 15.0 to 30% by weight of the whole composition. 0.0% by weight. When the amount is less than 2.0% by weight of the whole composition, the fit during use is poor, which is not preferable. When the amount is more than 40.0% by weight, the spread during use becomes heavy and the fit is poor. It is not preferable because it becomes excessive.

(Component (b)) Examples of the silicon dioxide powder used in the present invention include a general silicic anhydride powder and a silicon dioxide powder subjected to a surface treatment such as a dimethylsilylated silicic anhydride powder. Can be In the present invention,
All of these are included. By blending the silicon dioxide powder into the lipstick composition, it is possible to make the appearance (surface state) beautiful and uniform. The amount of the silicon dioxide powder in the lipstick composition is from 0.5 to the total amount of the composition.
It is 10.0% by weight, preferably 0.5 to 2.0. If the amount of the silicon dioxide powder is less than 0.5% by weight of the whole composition, it is difficult to make the appearance (surface state) beautiful, and if it exceeds 10.0% by weight, the spread during use becomes heavy. This is undesirable.

The lipstick composition of the present invention has a liquid oil content and / or a semi-solid oil content, that is, a normal temperature (0 ° C.), in the same manner as a usual lipstick composition, in order to adjust its usability as a whole.
-30 ° C) and an oil having a melting point near body temperature (37 ° C). These oils are not particularly limited as long as they are usually blended in a lipstick composition.

[0011] Such oils include, for example, cacao butter,
Castor oil, jojoba oil, macadamia nut oil, lanolin,
Natural oils such as olive oil; hydrocarbon oils such as petrolatum, liquid paraffin and polybutene; higher fatty acids, higher alcohols, synthetic ester oils of higher alcohols and fatty acids, dimethylpolysiloxane, polyoxyethylene sorbitan fatty acid esters, and the like. However, the present invention is not limited to these. These oils can be blended according to the specific embodiment of the lipstick composition of the present invention, and can be used not only alone but also in combination of two or more of the above oils. is there.

The color pigment and / or white powder other than the silicon dioxide powder which can be blended in the lipstick composition of the present invention is not particularly limited, and the color pigment and / or white powder usually blended in the lipstick composition are not particularly limited. Powders can be widely blended.

Examples of the coloring pigment and / or white powder include iron oxide, fish scale foil, Red No. 201 and 2
No. 02, No. 218, No. 223, Orange No. 201, coloring pigments such as calsamine and mica; white powders such as talc, kaolin, barium sulfate, calcium carbonate, titanium oxide, titanium oxide coated mica, nylon powder, etc. Examples include, but are not limited to: These color pigments and / or white powders can be blended according to the specific embodiment of the lipstick composition of the present invention. Can of course be used in combination.

Further, the lipstick composition of the present invention may optionally contain conventional components other than those described above which are conventionally compounded in the lipstick composition, as long as the desired effects of the present invention are not impaired. . Examples of such conventional components include ultraviolet absorbers such as octyl methoxycinnamate; blood circulation promoters such as vitamin E; humectants such as water and glycerin.
