Description

W / O makeup cosmetic composition having durability without transfer externally}

The present invention relates to a water-in-oil makeup cosmetic composition, and more particularly, to a water-in-oil makeup cosmetic composition which is excellent in durability by containing both a silicone resin and an acrylate-based copolymer in a continuous phase and does not appear after skin application. The present invention also relates to a water-in-oil type makeup cosmetic composition containing an acrylate copolymer in an aqueous phase together with a continuous phase.

Cosmetic compositions, in particular makeup compositions such as foundations, body make-up products, concealers, lipsticks, mascaras, eyeshadows and powders, generally consist of three components: oils, powders and water and can be classified according to their composition or formulation or purpose of use. Can be. In general, emulsified makeup is evaluated for quality, color expression, persistence, stability over time, and skin safety. Therefore, when applied to the skin, it should be applied lightly and softly, and its color should be clear and lasting for a long time. In addition, it should not be erased by sweat, water, sebum, etc., and it should be safe for skin without any change of physical properties during long time use and storage.

These makeup products have the disadvantage of being washed away or buried relatively easily due to daily physical activity. This means that the makeup will not last long and should be used regularly and repeatedly, and also that the composition may be partially deposited on certain substrates, such as glass, clothing, or skin, that are in contact. No one wants to use a lipstick that leaves a glass or a foundation that stains a white blouse collar.

Much research has been conducted to address these shortcomings. Most non-staining makeup cosmetic compositions consist of a film former and a volatile oil in a continuous phase so that the film is obtained as the oil evaporates. However, there is a disadvantage that this volatile component leaves an uncomfortable film after evaporation. In order to improve this, compositions including styrene-ethylene-propylene copolymers or copolymers using monoolefinically unsaturated carboxylic acid monomers and copolymers of aliphatic chain acrylic ester monomers have been proposed, but it is difficult to expect satisfactory effects and is not much after drying. It was not comfortable and often resulted in dry, non-moisturizing films.

There is a continuing need for makeup products that have no or little stain after being soft, moisturizing and comfortable.

Korean Patent Laid-Open Publication No. 1999-011035 discloses a water-in-oil type emulsion foundation composition containing a silicone gel having a siloxane bond as a main chain, trimethylsiloxysilicate, an acrylic-silicone copolymer, or a mixture thereof. 5,219,560 is a cosmetic composition comprising a dimethylpolysiloxane compound and an acrylic-silicone conjugated copolymer together with low viscosity silicone oil, partially crosslinked organopolysiloxane, low boiling oil, volatile solvent, volatile hydrocarbon, surfactant, or water The present invention is limited to partially crosslinked organic silicon used to impart a soft feeling such as gel in the above, so as to contain an appropriate amount of benzene without dissolving in benzene, and JP6-A-6. 72824 contains organopolysiloxanes, volatile low Here silicone oil or paraffinic hydrocarbons and is disclosed, but the cosmetic composition containing the oil-absorbing powder, there were also those limitations There provided a cosmetic bury and lasting others little.

Accordingly, the present inventors conducted a study for the preparation of a makeup cosmetic composition that does not appear, as a result, by containing a silicone resin and an acrylate copolymer in a continuous phase at the same time to produce a makeup cosmetic composition with excellent durability and no stain after applying the skin The present invention was completed by discovering that the above effects can be further enhanced by using an acrylate copolymer in the water phase.

Accordingly, it is an object of the present invention to provide a water-in-oil type makeup cosmetic composition having excellent durability and non-obtaining characteristics.
