Thus, one of the advantageous application of the cosmetic as a liquid foundation for summer use.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
This invention relates to a water-in-oil-type cosmetic and, more 
particularly, to a water-in-oil-type make-up cosmetic, which possesses an 
excellent emulsion stability, imparts a refreshing feeling to the skin 
upon application, and can be well retained on the skin after application. 
2. Description of the Background Invention 
Foundations, eye liners, mascaras, and the like are included in 
emulsion-type cosmetics for make-up use. They are classified into 
oil-in-water-type cosmetics (hereinafter referred to as "o/w type 
cosmetics") and water-in-oil-type cosmetics (hereinafter referred to as 
"w/p-type cosmetics") depending on the type of emulsion employed. 
As compared with oil-based cosmetics, these emulsion-type cosmetics impact 
a sense of refreshment and are less oily when applied to the skin because 
water is incorporated as their component. Additional features of the 
emulsion-type cosmetics are that they are prepared mostly in liquid or 
cream form and are well extendible on the skin, providing an evenly 
finished make-up. 
In particular, as compared with o/w type cosmetics, w/o-type cosmetics, 
being of a continuous oil phase, have a higher resistance to bacteria, 
form an oil film with a low water-permeability on the skin, which can 
protect the skin from becoming dry over a long period of time and does not 
re-emulsify when the same comes into contact with water on such occasions 
as swimming, washing, kitchen work, or sweating, thus preventing the 
make-up from running, cracking or becoming spottedly discolored. 
It has conventionally been difficult to formulate a stable w/o-type 
emulsion. In order to make a stable emulsion, it is sometimes necessary to 
restrict the amount of water to be incorporated in the dispersion phase or 
to employ an oil component with a higher viscosity for the continuous 
phase. This brings about drawbacks in which the cosmetics produce a 
stickiness or strong oily feeling upon use. 
For providing an emulsion cosmetic with better capability to refresh the 
user upon use, it is imperative that the cosmetic contain a smaller amount 
of low viscosity oil components. 
Polysiloxanes (hereinafter sometimes referred to as "silicone oils") of 
formulae (II), (III) and (IV) hereinafter described are suitable oil 
components for cosmetics since they are capable of forming a thin, 
homogeneous film on the skin and imparting a less sticky, smoother 
feeling. These silicone oils, however, are insufficiently compatible with 
commonly used surface active agents and other oil components. Furthermore, 
they are not readily emulsifiable so that it is very difficult to obtain a 
fine homogeneous, emulsion from them. 
Another effective way of providing a cosmetic with good refreshing 
capability upon use is to incorporate ethyl alcohol in it. Addition of 
ethyl alcohol to an emulsion, however, greatly impairs the stability of 
the emulsion system. 
Because of these reasons, the wide, popular use of w/o-type cosmetics is 
restricted in spite of their advantages over o/w-type cosmetics. 
Therefore, development of w/o-type cosmetics featuring higher stability 
and the provision of a better, more refreshing feeling upon use has long 
been desired. 
In light of this background, the present inventors have conducted extensive 
studies for overcoming the above-mentioned problems in preparing w/o-type 
cosmetics. As a result, the inventors found that a highly stable w/o-type 
cosmetic which gives a fine refreshing feeling upon use, and which can be 
well retained on the skin after application, can be prepared by using a 
specific type of dimethylpolysiloxanepolyoxyalkylene copolymer as an 
emulsifier; by providing an oil phase comprising a silicone oil and a 
cosmetic powder the surface of which is treated to make the same 
water-repellent; and by adding to this oil phase a water phase containing 
a specified proportion of ethyl alcohol. These findings have led to the 
completion of this invention. 
SUMMARY OF THE INVENTION 
Accordingly, an object of this invention is to provide a water-in-oil-type 
cosmetic comprising as its effective components: 
(a) 0.05-5% by weight of a dimethylpolysiloxanepolyoxyalkylene copolymer 
represented by the following general formula (I): 
##STR1## 
in which a is a value of 1-5, b is a value of 7-15, c is a value of 0-4, m 
is a value of 20-100, n is a value of 1-5, and R represents a hydrogen 
atom or an alkyl group having 1-5 carbon atoms; 
(b) 7-60% by weight of oil components, wherein not less than 60% by weight 
of at least one kind of polysiloxane represented by the following 
formulae, (II), (III), or (IV), is contained: 
##STR2## 
in which x is a value of 1-100, z is a value of not less than 1, y+z is a 
value of 1-100, and .iota. is a value of 2-6; 
(c) 3-60% by weight of a cosmetic powder of which the surface is treated to 
provide water-repellence; and 
(d) 15-80% by weight of an aqueous solution of ethyl alcohol, wherein the 
proportion by weight of ethyl alcohol/water is 50/50-2/98. 
Other objects, features, and advantages of this invention will be more 
fully understood by the following detailed description and preferred 
embodiments of the invention. 
DETAILED DESCRIPTION OF THE INVENTION AND PREFERRED EMBODIMENTS 
The dimethylpolysiloxanepolyoxyalkylene copolymer, component (a) of the 
w/o-type emulsion cosmetic of this invention is insoluble in water. When 
water-soluble dimethylpolysiloxanepolyoxyalkylene copolymer is used, the 
resulting emulsion tends to have larger emulsion particles. This renders 
the product less stable, causing separation of the water phase components 
during storage over a prolonged period of time. In addition, since a water 
soluble dimethylpolysiloxanepolyoxyalkylene is hydrophilic itself, when 
the w/o-type emulsion cosmetic containing the same comes into contact with 
water or sweat, the w/o-type emulsion cosmetic tends to re-emulsify, which 
may lead to breaking or cracking of the make-up. 
Desirable examples of component (a) are those 
dimethylpolysiloxanepolyoxyalkylenes of formula (I), and particularly 
those when R in formula (I) is a hydrogen atom, a is 3, b is 7-15, c is 0, 
m is 20-100, more desirably 50-100, and n is 1-5. One example of such 
dimethylpolysiloxanepolyoxyalkylene which can be readily available is 
Toray Silicone SH 3775C manufactured by Toray Silicone Co., Ltd. 
This component (a) is formulated in the w/o-type emulsion cosmetic of this 
invention in an amount of 0.05-5% by weight (hereinafter referred to 
simply as "%"), and preferably 0.1-2%. Formulating this component in 
excess of 5% does not produce any enhanced effect, and will thus bring 
about no better economy. On the other hand, if the amount is less than 
0.05%, adverse effect is exhibited by this component, giving a product 
with poor prolonged stability. 
Component (b) of the w/o-type emulsion cosmetic according to the present 
invention is comprised of at least 60% polysiloxane and less than 40% 
other oil components. Among the polysiloxanes, preferred are those having 
an .iota.-value of between 3 and 5 in formula (IV). Since these 
polysiloxanes are volatile, they are not retained on the skin when used as 
a cosmetic component, enabling them to impart a refreshing feeling to the 
skin free of stickiness or oilness. In addition, these polysiloxanes are 
more stable over a prolonged period of time than polysiloxanes represented 
by formulae (II) or (III). Specific examples of these polysiloxanes 
readily available on the market are SH244, SH344, SC245, and DC345 (Trade 
names; manufactured by Toray Silicone Co., Ltd.), KF994, KF995, KF996, and 
KF9956 (Trade names; manufactured by Shinetsu Kagaku Kogyo Co., Ltd.), and 
TSF404, TSF405, and TSF406 (Trade names; manufactured by Toshiba Silicone 
Co., Ltd.). 
Given as examples of oil components other than polysiloxanes of component 
(b) of this invention are hydrocarbons such as liquid paraffin and 
squalane, oils and fats derived from animals or vegetables such as olive 
oil and jojoba oil, synthetic esters such as octyldodecyl myristate, 
isopropyl palmitate, isopropyl myristate, and the like. 
When less than 60% polysiloxanes are formulated in this component (b), the 
emulsion particles tend to be larger and it is difficult to maintain the 
product for a long period of time. 
Component (b) is formulated in the w/o-type emulsion cosmetic of this 
invention in an amount of 7-60%, preferably 15-40%. When the proportion is 
less than 7%, the emulsion obtained is less stable. On the other hand, if 
the proportion is more than 60%, the refreshing feeling imparted by the 
water phase components is impaired. 
Component (c) of the w/o-type emulsion cosmetic of this invention is a 
cosmetic powder surface of which is treated so as to make it 
water-repellent. The cosmetic powder may be any organic or inorganic 
powdery material commonly used for cosmetics, and includes, for example, 
extenders such as talc, cericite, mica, kaolin, silica, nylon powder, 
polyethylene powder, silk powder, or cellulose powder; pigments or 
coloring materials such as titanium oxide, iron oxide, zince oxide, 
ultramarine blue, iron blue, chromium oxide, coloring agents derived from 
organic tars, and lakes; or composites pigments such as titanium-mica, 
iron oxide coated-mica, or the like. Examples of water-repellence donating 
reagents are silicones, higher fatty acids, higher alcohols, fatty acid 
esters, metallic soaps, amino acids, alkyl phosphates, fluoroalkyl 
surfactants, fluoroalkyl polymers, and the like. 
The method of treating the surface of a cosmetic powder may be a 
conventional one. Typically, (i) the water-repellence donating reagent is 
dissolved in an organic solvent such as hexane, toluene, benzene, or the 
like, (ii) a cosmetic powder is then added to this solution, and (iii) the 
organic solvent is removed from the mixture by evaporation or other 
suitable means. The amount of the water-repellence donating reagent may be 
0.5-20% by weight, and preferably 1-10% by weight, in the treated powder. 
A preferred example of component (c) is a cosmetic powder obtained by 
treating its surface with silicone. This type of cosmetic powder has the 
strongest water-repellence, and can effectively prevent the make-up from 
breaking down when applied to an emulsion cosmetic. In addition, the 
emulsion is dense and fine, and exhibits excellent stability for a long 
period of time. Although a cosmetic powder without being treated by a 
water-repelling reagent can provide relatively stable emulsions, make-up 
produced using such cosmetics is very liable to break down by water or 
sweat due to hydrophilic nature of the surface of the cosmetic powder. 
This component (c) is formulated in the w/o-type emulsion cosmetic of this 
invention in an amount of 3-60%, preferably 7-30%. If the proportion is 
less than 3%, the composition cannot exhibit an adequate coloring effect 
required for a cosmetic intended for make-up purpose. Formulation in 
excess of 60%, on the other hand, makes the cosmetic too powdery and 
diminishes its refreshment capability which is the purpose of this 
invention. 
It is essential for the w/o-type emulsion cosmetic of this invention that 
the ratio of ethyl alcohol/water of component (d) be in the range of 
50/50-2/98, and preferably 35/35-5/95. A sufficient refreshing feeling 
cannot be obtained with an ethyl alcohol/water ratio smaller than 2/98. If 
the ratio is larger than 50/50, the stability of the emulsion is impaired, 
and the composition obtained gives a strong stimulus to the skin. 
This component (d) is formulated in the w/o-type emulsion cosmetic of this 
inventin is an amount of 15-80%, and preferably 30-70%. If the proportion 
is less than 15%, the refreshing effect when applied to the skin is 
insufficient. Formulation of this component in excess of 80% impairs the 
long-range stability of the product. 
Various ingredients may be formulated in component (d) as required. These 
may be humectants, including glycerol, sorbitol, maltitol, propylene 
glycol, dipropylene glycol, 1,3-butylene glycol, sodium pyrrolidone 
carboxylate, polyoxyethylenemethyl glucoside, polyoxypropylenemethyl 
glucoside, glucose, and the like; amino acids such as glycine, serine, and 
proline; and other agents with pharmaceutical effects such as 
antiphlogistics, antiseptics, vitamins, and the like. 
Preparation of the w/o-type emulsion cosmetic according to this invention 
may, for instance, be carried out as follows. 
Component (a) is first added to component (b) and the mixture is stirred to 
disperse the former in the latter. To this mixture is added component (c), 
and then component (d) is added a bit at a time while stirring to obtain 
the target w/o-type emulsion cosmetic. This procedure may be carried out 
at a temperature in the range of 5.degree.-90.degree. C., with the 
w/o-type emulsion cosmetic featuring excellent stability capable of being 
prepared at any temperature in this range. 
One of the outstanding features of the w/o-type emulsion cosmetic of this 
invention thus prepared is in the state of the emulsion particles. When 
the particles are examined by microscope, the normally observed state is 
that in which the particles of the cosmetic powders adhere to the surface 
of the water-phase particles having diameters of 10-50 .mu.m. If such 
particles of cosmetic powders exist inside the water-phase particles, such 
emulsions cannot remain stable for a long period of time. Another feature 
of the emulsion is that although the emulsion particles are very stable 
while the product is shaken or left to stand, they readily separate if 
coated to form a thin film and some slight shear is applied to it. This is 
evidenced by the fact that the same phenomenon takes place when the 
cosmetic is applied to the skin. More specifically, it is presumed that 
although the cosmetic is in fact a water-in-oil-type emulsion, the 
emulsion is broken down upon application to the skin, allowing the water 
phase components including ethyl alcohol to come into contact with the 
skin, bringing about a refreshing feeling to users. 
It is desirable that the w/o-type emulsion cosmetic of this invention have 
a low viscosity. If the viscosity is high, it cannot provide a refreshing 
feeling both in terms of appearance and actual application. 
During storage over a long period of time, a small amount of oil phase 
components may separate and form a layer on top of the composition. Such a 
product can be used as a shake-type cosmetic if its viscosity is small 
enough to make the composition homogeneous by slightly shaking the same. 
The w/o-type emulsion cosmetic of this invention is a liquid or creamy 
cosmetic which produces a refreshing feeling upon use, does not generate 
an oily, sticky feel, and prevents the make-up from breaking down by water 
or sweat. 
There is no special limitation to the specific application of the w/o-type 
emulsion cosmetic according to this invention, so long as such an 
application is directed to make-up cosmetics containing a cosmetic powder. 
A typical example of the application for making the best use of the 
advantageous features of this w/o-type emulsion cosmetic, i.e., providing 
a highly satisfactory refreshing feeling and preventing the make-up from 
cracking or breaking down, is as a foundation. When the w/o-type emulsion 
cosmetic of this invention is realized as being a liquid possessing the 
above-mentioned features, a particularly advantageous application for the 
product is as a liquid foundation for summer use. 
Well known as liquid foundations for use in summer are those of the 
suspension type wherein an untreated cosmetic powder is suspended in a 
water phase containing ethanol. The untreated cosmetic powder of such a 
suspension type-foundation sedimentates, and the water phase separates 
when the foundation is left to stand. Moreover, a critical drawback of 
this type of liquid foundation is that it tends to cause the breaking or 
cracking of make-up due to exposure to water or sweat. 
The w/o-type emulsion cosmetic of this invention overcomes such this 
disadvantage. 
Other features of the invention will become apparent in the course of the 
following description of the exemplary embodiments which are given for 
illustration of the invention and are not intended to be limiting thereof.

entire mixture. The emulsion was transferred to a glass container and left 
to cool at room temperature.
