Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid water-in-oil type cosmetic which is filled in a container such as a compact container, a metal plate, a stick container, a middle plate, etc. The present invention also relates to a solid water-in-oil type cosmetic which is excellent in refreshing and moist feeling at the time of application, and is also excellent in persistence of makeup after application.

[0002]

2. Description of the Related Art Water-in-oil cosmetics are useful dosage forms capable of forming a water-resistant cosmetic film on the skin, but have a large amount of oil, so that they become sticky and greasy when applied. Was a disadvantage. There has been a technique for blending a volatile silicone oil into the oil to improve this disadvantage. But,
The water-in-oil type cosmetic using this volatile silicone oil was difficult to secure the stability over time. Further, conventional water-in-oil cosmetics are mostly in the form of emulsion or cream, and as containers for filling these cosmetics, glass or resin bottles or tube containers are generally used. Was used. However, glass bottles are generally heavy and thus have poor portability, and tube containers have good portability. However, there is a concern that the tube may be ruptured by other luggage in a bag or the like and the tube may burst and the contents may leak. In recent years, a solid water-in-oil cosmetic has been developed to meet such market demands. For example, JP-A-01-7
As described in JP-A-9104, there is a technique for preparing a solid water-in-oil emulsified cosmetic from a specific polyoxyalkylene-modified organopolysiloxane and a solid oil.

[0003]

However, the specific polyoxyalkylene-modified organopolysiloxane has poor compatibility with solid oil, which is an essential component for solidification, and the cosmetic is heated and fluidized to obtain a container. When filling
The heating tends to make the oil content non-uniform, which may cause deterioration in quality and stability over time in some cases. At the same time, when the cosmetic is heated and fluidized and filled into a container, the water in the internal aqueous phase is liable to evaporate due to the heating, which may cause deterioration in quality and stability over time. Therefore, development of a solid water-in-oil type cosmetic which is excellent in filling moldability, stability over time, and excellent in usability has been desired.

[0004]

Means for Solving the Problems In view of the above circumstances, the present inventors have made intensive studies and as a result, have found that a solid water-in-oil type containing water in an oil containing volatile silicone oil and solid oil. The use of long-chain alkyl-containing polyoxyalkylene-modified organopolysiloxanes in cosmetics allows for non-uniform oil content and water evaporation when filling cosmetics into compact containers, gold plates, stick containers, middle plates, etc. Is suppressed, and a cosmetic having excellent filling moldability and stability over time can be obtained.Furthermore, this solid water-in-oil cosmetic has a good refreshing sensation and a good moist feeling, and also has a good makeup persistence after application. The present invention was found to have excellent organoleptic properties, and thus completed the present invention. That is, the present invention comprises the following components (a) to (d): (a) a long-chain alkyl-containing polyoxyalkylene-modified organopolysiloxane (b) volatile silicone oil (c) solid oil (d) aqueous component It is intended to provide a solid water-in-oil cosmetic which is characterized in that: Furthermore, by containing, as the component (e), a water evaporation inhibitor at least selected from an inorganic salt, a water-soluble polymer, an organic acid or a salt thereof, an amino acid or a salt thereof, polyethylene glycol, and a saccharide, the filling moldability is improved. And a solid water-in-oil cosmetic which further improves aging stability.
