Description

Cosmetic composition for lip makeup in oil dispersion formulation, and preparation method thereof}

It relates to a cosmetic composition for lip makeup in an oil-dispersible formulation and a manufacturing method thereof.

In the case of a liquid lip product with a velvety texture containing an excessive amount of silicone crosspolymer, it forms a thick makeup film and has a high color development and clear makeup effect, but has a disadvantage that the lips are stuffy and dry. In order to solve this problem, in the case of a velvet texture product having a soft and thin makeup film with low viscosity, it is comfortable to use, but has a disadvantage that the makeup effect is insufficient because the makeup film is thin. In addition, in the case of existing oil-dispersion velvet lip products, dimethicone/dimethicone crosspolymer or dimethicone/vinyldimethicone crosspolymer is used as the silicone crosspolymer, so it is difficult to directly include a water-soluble moisturizer. there was

Therefore, it is necessary to develop a cosmetic composition for lip makeup of an oil dispersion formulation capable of solving dryness of the lips while maintaining a matte texture.

silicone crosspolymers containing hydrophilic moieties; And it provides a cosmetic composition for lip makeup of an oil dispersion formulation containing a water-soluble moisturizer.

It provides a method for preparing the cosmetic composition for lip makeup of the oil dispersion formulation.

One aspect is a silicone crosspolymer comprising a hydrophilic moiety; And it provides a cosmetic composition for lip makeup of an oil dispersion formulation containing a water-soluble moisturizer.

The cosmetic composition uses a silicone crosspolymer containing a hydrophilic moiety, thereby using a dimethicone/dimethicone crosspolymer or a dimethicone/vinyldimethicone crosspolymer, which was difficult to directly include a water-soluble moisturizer. Unlike dispersion formulations, water-soluble moisturizers can be incorporated directly into oil dispersion formulations. Accordingly, it is possible to significantly improve the feeling of dryness of the lips and improve the feeling of use. In addition, although the moisturizing and application properties were improved, the matte texture unique to the oil-dispersion cosmetic composition for lip makeup was maintained.

The silicone crosspolymer is a copolymer in which silicone components are crosslinked. Examples of the silicone component include dimethicone, vinyldimethicone, cyclopentasiloxane, cyclohexasiloxane, dimethiconol, phenyltrimethicone, amodimethicone, cetyldimethicone, cyclomethicone, etc. , Any conventional silicone component used in cosmetics can be used without limitation.

The cosmetic composition includes a silicone crosspolymer containing a hydrophilic moiety. The type of the hydrophilic moiety is not limited as long as it is a moiety capable of imparting hydrophilicity to the silicone crosspolymer. Since hydrophilicity is imparted to the silicone crosspolymer by containing a hydrophilic moiety, “silicone crosspolymer containing a hydrophilic moiety” may be used interchangeably with “hydrophilic silicone crosspolymer”. The hydrophilic moiety may be combined with a water-soluble moisturizer to stably contain the water-soluble moisturizer in a formulation.

In one embodiment, the hydrophilic moiety may be polyethylene glycol (PEG), polypropylene glycol (PPG), polyglyceryl, or a combination thereof, but is not limited thereto.

For example, the hydrophilic moiety can be PEG. The PEG is PEG-2, PEG-3, PEG-6, PEG-9, PEG-10, PEG-11, PEG-12, PEG-13, PEG-14, PEG-15, It can be classified into PEG-20, PEG-40, etc., and the type is not limited as long as it can impart hydrophilicity to the silicone crosspolymer.

For example, the hydrophilic moiety can be PPG. The PPG can be classified into PPG-2, PPG-3, PPG-6, PPG-10, PPG-20, etc. according to the number of moles of propylene oxide added, and if it can impart hydrophilicity to the silicone crosspolymer, that type Not limiting.
