Abstract

PURPOSE:To obtain the subject stable cosmetic excellent in feeling of use by using a specific polyoxyalkylene alkyl ether-comodified organopolysiloxane as an emulsifying agent and stably blending oils within a wide range of nonpolar to polar oils and a large amount of water. CONSTITUTION:A solid water-in-oil type emulsified cosmetic is obtained by using a polyoxyalkylene alkyl ether-comodified organopolysiloxane expressed by formula I [R<1> is alkyl; R<2> is formula II (Q<1> is hydrocarbon; R<6> is H, alkyl or acetyl; a is an integer of >=1; b is an integer of >=0) ; R<3> is the formula Q<2>-O-R<7> (Q<2> is hydrocarbon; R<7> is hydrocarbon); R<4> and R<5> are any one of R<1> to R<3>; 1 is 6; m and n are a] and stably blending oils within a wide range of nonpolar to polar oils such as triglycerides, ester oils hydrocarbons, a solid wax and a large amount of water. The above-mentioned cosmetic has light extensibility and is refreshing without stickiness and excellent in both usability and feeling in use. The cosmetic is used as a solid product such as a solid cream, a solid foundation, a lipstick, lip cream or an eye cream.

Description

Detailed Description of the Invention

[0001]

The present invention has good stability over time,
The present invention relates to a solid emulsified cosmetic composition having excellent usability and usability.

[0002]

2. Description of the Related Art Solid water-in-oil type emulsion cosmetics are generally solid oily type in which oil is solidified and solid press type in which powder or a mixture of powder and an oil agent is pressed. The former includes stick-shaped cosmetics such as lipsticks, and the latter includes foundations and the like, and these are used properly according to the purpose and method of use.

[0003]

However, solid cosmetics have problems in stickiness, spread weight, hardness, etc. peculiar to oil when used, and it has been attempted to add water in order to improve these problems. However, since it is difficult to stably mix a large amount of water, even if water is mixed, the amount thereof is extremely small, and there is no great difference in the feeling of use from the conventional one.

[0004]

Under such circumstances, the present inventor has conducted diligent research and, as a result, uses a polyoxyalkylene alkyl ether co-modified organopolysiloxane represented by the following general formula (1) as an emulsifier. As a result, a stable solid water-in-oil type emulsified cosmetic composition with a wide range of oils from non-polar oils such as triglycerides, ester oils, hydrocarbons to polar oils and a large amount of water can be added stably. I succeeded in getting a fee.

That is, the present invention provides the following components (a)-
(D) (a) Oil agent (b) Solid wax (c) Water (d) General formula (1)

[0006]

[Chemical 2]

The present invention provides a solid water-in-oil type emulsified cosmetic containing a polyoxyalkylene alkyl ether co-modified organopolysiloxane represented by:

In the present invention, as the oil agent of the component (a), aliphatic hydrocarbons such as liquid paraffin and squalane; animal and vegetable oils such as mink oil, jojoba oil and castor oil; cetyl isooctanate, octyldodecyl myristate, Ester oils such as isocetyl stearate; glycerides such as glyceryl trioctanoate and glyceryl triisostearate; higher alcohols such as oleyl alcohol and isostearyl alcohol; oleic acid,
Examples include higher fatty acids such as isostearic acid.
The blending amount of the component (a) is 10 to 90% by weight of the total cosmetic composition.
(Hereinafter, simply indicated by%) is preferable.

The solid wax as the component (b) includes petroleum waxes such as paraffin wax and microcrystalline wax; mineral waxes such as ozokerite and ceresin; one or more natural waxes such as carnauba wax and candelilla wax. A mixture may be mentioned.
The component (b) is preferably blended in an amount of 5 to 40% with respect to the component (a), and 2.5 to 30% of the total cosmetic composition.

The water as the component (c) is 1 to 4 of the total cosmetic composition.
0% is preferable, and if it is less than 1%, the characteristic of containing water is difficult to appear, and if it exceeds 40%, it becomes hard to become a solid type.

The polyoxyalkylene alkyl ether co-modified organopolysiloxane as the component (d) is a liquid or paste which is represented by the general formula (1) at room temperature. This is a compound not described in the literature, but it can be easily produced by co-modifying methylhydrogenpolysiloxane with polyoxyalkylene allyl ether and allyl alkyl ether, for example, according to the method shown in the reference example described later. The blending amount of component (d) in the cosmetic is preferably 0.01 to 10% of the total composition. If it is less than 0.01%, it is difficult to exhibit a sufficient emulsifying ability, and if it exceeds 10%, the viscosity becomes high and the spread becomes heavy, and the feeling of use becomes poor, which is not preferable.

The solid water-in-oil type emulsion cosmetic of the present invention comprises:
In addition to the above essential components, commonly used aqueous and oily components such as moisturizers, preservatives, antioxidants, ultraviolet absorbers, cosmetic ingredients, fragrances, fragrances, thickeners, gelling agents, color pigments. , Luster pigments, organic powders, hydrophobized pigments, tar dyes and the like can be added within a range that does not impair the effects of the present invention.

The solid water-in-oil type emulsified cosmetic composition of the present invention includes solid products such as solid cream, solid foundation, lipstick, lip balm, eye cream and solid eye shadow. These are produced from the above components by a conventional method.

[0014]

The solid water-in-oil type emulsion cosmetic of the present invention comprises:
Since a large amount of water can be blended in a stable manner, the problems of usability such as stickiness, weight of spread, and hardness that are often found in the cosmetics are solved, and a refreshing feeling of use can be obtained, and at the time of selecting the oil content. There are no restrictions, and it has become possible to expand the usability.
