DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an oil-in-water type cosmetic composition, and more specifically, relates to an oil-in-water type solid composition fit for foundation, eye shadow, lipstick, etc.
BACKGROUND ART
As types of solid cosmetics which have so far generally been used, there are solid, oily types wherein an oil is solidified with a wax; solid, pressed types wherein a powder or a mixture of a powder and an oil is pressed; solid, water-in-oil type emulsification types which comprise a specific oil solidifying agent, a powder subjected to a treatment for making it hydrophobic, water, and a lipophilic surface active agent; etc., and they are used appropriately in accordance with the use objects and use methods of the respective cosmetics.
Among them, solid, water-in-oil type emulsification types are, particularly, good in stability and water resistance, and further have a wet use feeling, and one obtained by emulsifying a silicone oil, solid wax and water with a polyoxyalkylene-modified organopolysiloxane is known (Japanese Laid-open Patent Publication No. 79104/1989). However, since in these water-in-oil type emulsification types, the oil component and the oil solidifying agent are compounded in their outer phase, they are inferior to oil-in-water type milky lotions and creams in "being fresh-looking", "refreshed feeling" and "being free of stickiness".
Further, as an example of products obtained by solidifying an oil-in-water type emulsification type, one obtained by compounding a large amount of a higher alcohol or a clay mineral is known. However, in this oil-in-water type emulsification type, due to the above components compounded in a large amount, "being fresh-looking", "refreshed feeling" and "being free of stickiness", which oil-in-water type milky lotions and creams naturally have, are lost. As other examples of solid oil-in-water type emulsification types, there are known, for example, one obtained by solidifying water of the outer phase with a fatty acid soap (Japanese Laid-open Patent Publication No. 279319/1991), and one obtained by conducting solidification with combined use of a water soluble solidifying agent and a water soluble sticking agent (Japanese Laid-open Patent Publication No. 178723/1993 and Japanese Laid-open Patent Publication No. 17828/1995). However, as to the former, since its soap content is high, its pH becomes high, and therefore, there are problems on stimulation of skin and safety, and as to the latter, there are problems that sufficient hardness cannot be obtained, and it is hard to use with a sponge.
Further, as an emulsification technique developed in recent years, there is known a technique wherein a water insoluble composite is formed from an amphoteric surface active agent and a higher fatty acid, and emulsification stability is secured with this composite acting as an interfacial membrane for emulsification (Japanese Laid-open Patent Publication No. 166367/1991), but even by using this technique, it has been difficult to obtain a solid emulsification type, moreover "being fresh-looking", "refreshed feeling" and "being free of stickiness".
On the other hand, milky lotions and creams are generally fluid in the range of 0.degree. C. to 50.degree. C., and therefore, made into vessel forms of bottles or tubes, and a little inferior in the aspect of portability and easiness of use, and particularly in the case of foundation, the tendency has been conspicuous.
Under the above circumstances, it is the actual situation that a solid and emulsification composition is not obtained which is a solid and which is good in portability and easiness of use, and moreover, has use feelings of "being fresh-looking", "refreshed feeling" and "being free of stickiness" which milky lotions and creams have.
Thus, the object of the invention lies in providing a composition which exhibits use feelings of "being fresh-looking", "refreshed feeling" and "being free of stickiness" which oil-in-water type milky lotions and creams have, is excellent in portability and easiness of
