Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an oily cosmetic containing a specific liquid oil agent, a fluorine-based oil agent, glycols, a powder, a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer, and more specifically, The present invention relates to obtaining an oily cosmetic having excellent dispersibility, usability, and finish of the system and having excellent makeup retention.

[0002]

2. Description of the Related Art Conventionally, it has been difficult for oily cosmetics such as lipsticks, eyeliners, eye shadows and oily foundations to have good usability and makeup retention at the same time. However, it had a defect that it adhered to clothes and was likely to cause bleeding. In order to eliminate this drawback, various studies have been made conventionally. For example, those with a dye to improve makeup retention by dyeing on the lips, those with a large amount of solid components such as wax to strengthen the coating and reduce color transfer, volatile oils and coatings. Compounded with a forming agent, the volatile oil agent volatilizes after application to eliminate color transfer due to the pigment and wax remaining, and a fluorine-based oil agent is added to impart water and oil repellency, and Examples include those with improved color retention.

[0003]

However, the one containing the dye is liable to dry the coated part with time, and the one containing a large amount of the wax has a large elongation and is not easy to use. In addition, those containing a volatile oil agent and a film-forming agent do not have a gloss over time after coating and the coated portion dries. Further, since the fluorine-based oil agent has poor compatibility with other oil agents, it has a drawback that it is difficult to uniformly disperse it in a system having a large amount of oil.

[0004]

Under such circumstances, the inventors of the present invention have conducted extensive studies and as a result, as a result, a specific liquid oil agent, fluorine-based oil agent, glycols, powder, carboxyvinyl polymer and / or alkyl-modified carboxyvinyl. The present inventors have found that an oily cosmetic containing a polymer is excellent in dispersibility, usability and makeup retention of the system, and completed the present invention. That is, the present invention provides the following components (A), (B),
(C), (D) and (E); (A) Oily base having an IOB value of 0.2 or more and liquid at room temperature (B) Fluorine-based oil agent (C) Glycols (D) Powder (E) ) An oily cosmetic comprising a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer.

As the oily base of the component (A) used in the present invention, any oily base having an IOB value of 0.2 or more and being liquid at room temperature can be used. Examples thereof include diglyceryl triisostearate, glyceryl trioctanoate, triglyceride 2-ethylhexanoate, propylene glycol dicaprate, oleyl alcohol, castor oil, and the like, and one or more of them can be used as necessary. The oily base of the component (A) of the present invention is blended in the oily cosmetic in the range of 0.5 to 90% by weight (hereinafter simply referred to as "%"). Within the range, good dispersibility and makeup retention can be obtained, but outside the range, dispersibility of the system is not preferable.

The fluorine-based oil agent of the component (B) used in the present invention is a perfluoroorganic compound which is liquid at room temperature, and includes, for example, perfluoroalkane and perfluoropolyether represented by the following general formula (1). Etc.
