Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-based cosmetic containing a powder, which has a good feeling in use, is excellent in water resistance and sweat resistance, has no skin irritation, and has good stability over time.

[0002]

2. Description of the Related Art In the past, water white powder and the like have been used as a cosmetic containing powder and water. This type of cosmetic contains a large amount of water, so it has a refreshing sensation and a refreshing feeling of use.However, it usually consists of water, powder, humectant, etc. However, there were drawbacks in that it lacked smoothness, had a powdery finish, and had extremely poor makeup durability, water resistance, and sweat resistance over time. In addition, it is separated into two layers of water and powder at the time of standing, and it is necessary to shake it when using it, and it is difficult to make uniform makeup. In general, extender pigments such as talc, kaolin, and mica are used as the powder, but it is difficult to mix a large amount of the pigment due to sedimentation due to sebum. As a means of uniformly dispersing these powders in an aqueous system, a method of forcibly dispersing them by mechanical force or a method of mixing and dispersing a large amount of a surfactant has been used. There is a problem that irritation to the skin and the long-lasting makeup deteriorate over time.

[0003]

As a method for remedying the above-mentioned drawbacks, use of a water-repellent / oil-repellent powder, a lower alcohol, an acrylic acid-based emulsion polymer, an alkali agent and an aqueous component is easy to use. It has been found that a cosmetic having a good feel at the time of use, excellent persistence of makeup, and good stability over time can be obtained. However, in some cases, creaking and emollient feeling are not always satisfactory.

[0004]

The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that a compound-treated powder having a specific perfluoropolyether group, a lower alcohol, an acrylic acid-based emulsion polymer, By containing an alkali agent and an aqueous component, it is easy to use, has a good feel at the time of use, and has excellent cosmetic persistence and stability over time. On the other hand, even if a large amount of powder is blended, it is possible to obtain a cosmetic with a good emollient feeling without being affected by the smoothness of spreading without being squeaky and having an excellent emollient feeling. They have found and completed the present invention.

That is, the present invention provides the following component (a):
(B), (c), (d) and (e): (a) perfluoropolyether alkyl phosphoric acid and its salt, perfluoropolyether alkyl sulfate and its salt, perfluoropolyether alkyl carboxylic acid and its salt A powder treated with a compound having a perfluoropolyether group having a molecular weight of 300 or more, (b) a lower alcohol, (c) an acrylic acid-based emulsion polymer, (d) an alkali agent, and (e) an aqueous solution. It is intended to provide an aqueous cosmetic containing the components.

It is necessary, and therefore, the compound preferably contains at least one or more oxyalkylene groups. More preferably, it is 1-2. This is because the presence of three or more oxyalkylene groups results in poor water / oil repellency of the compound. Similarly, an alkylene group may be contained in addition to the oxyalkylene group in terms of the fixing force. The preferred carbon number of the alkylene group is 2
It is as follows.

Examples of the compound having a perfluoropolyether group include perfluoropolyether alkyl phosphoric acid and salts thereof, perfluoropolyether alkyl sulfate and salts thereof, and perfluoropolyether alkyl carboxylic acid and salts thereof.
