Description

Cosmetic composition for skin pores reduction containing RX complex blood {COSMETIC COMPOSITION FOR REDUCING® SKIN PORE COMPRISING RX COMPLEX P}

The present invention relates to a cosmetic composition for reducing skin pores containing RX complex blood made by mixing mentillactate, deficiency extract and betaine salicylate in a certain ratio.

Human skin contains about 15-20% moisture, and the human body contains about 70-75% moisture. Skin protects our bodies from various external stimuli and acts as a barrier against the moisture inside our bodies. The sebaceous gland, which is an appendage of the skin, secretes sebum to the outermost layer of skin through pores and plays an important role in the body's defense action. However, when the secretion of sebum is excessive, the skin becomes shiny, the skin is inflamed well, acne is provoked, and bacterial infections cause folliculitis. On the other hand, if the sebum secretion on the surface of the skin is small, the skin becomes dry, which causes skin diseases. When the sebum is discharged from the pores, the amount of the pores varies according to the condition of the pores to control the condition of the pores can also be a very important factor in skin care.

The pores, the pathways that secrete sebum, are distributed throughout the skin of the face, but the nose and cheek areas can be identified with the naked eye, and the appearance of the pores is influenced by endogenous and exogenous factors such as sex, genetics, aging, acne and chronic UV exposure. There are individual differences by. As you enter puberty, the androgen, a male hormone, increases, and the sebaceous glands are activated, which increases sebum secretion and pores. The size of the pores increases due to skin collagen and elastic fibers due to skin aging, decreased skin elasticity, excessive sebum secretion and thickened stratum corneum due to hyperkeratosis.

As the pores become wider, bacteria are more likely to invade them, leading to skin problems such as acne and rashes. In addition, when the pores are widened, not only does not receive makeup well, it looks dull and dirty, and wastes such as fine dust or makeup residues are caught, and the large pores are more prominent, so the face looks dirty. Accordingly, many people have great interest in pore contraction (contraction), so the management of pores through cosmetics is important.

Attempts have been made to control pore size using various natural products. Korean Laid-Open Patent No. 2017-0016408 discloses a cosmetic composition exhibiting pore contraction effect by including pine nut bark extract as an active ingredient.

In addition, Korean Patent Publication No. 2017-0045085 discloses a cosmetic composition exhibiting a pore shrinkage effect, including a complex containing pine bark extract, ascorbic acid, vitamin E and gamma linolenic acid.

Hereinafter, the present invention will be described in detail.

The present invention makes mentyl lactate, betaine salicylate and deficiency extract in one complex, and contains the same to provide a cosmetic composition having an excellent pore reduction effect.

In the present invention, the complex prepared by containing menthyl lactate, betaine salicylate and extractor extract in a certain ratio is referred to as RX complex blood (P).

Cosmetic composition according to the present invention has the effect of improving skin pores, pore control and pore reduction.

Menthyl lactate of the present invention is a component of the ester combination of menthol and lactate is mainly used as a skin conditioning agent.

Betaine salicylate of the present invention is a material obtained by combining betaine and salicylic acid is mainly used in cosmetics having the effect of improving acne, inflammation and the like.

RX complex blood according to the present invention may include a menthyl lactate, betaine salicylate and the extract extract in a weight ratio of 1 to 3: 1 to 5: 1 to 5, more preferably 3: 5: 5 It can be included as.

RX complex blood according to the present invention is preferably included in 1.0 to 30.0% by weight relative to the total weight of the cosmetic composition. If the RX complex P is less than 1.0% by weight, the sebum control effect is insignificant, and if it exceeds 30.0% by weight, the economic efficiency is low compared to the effect, and may be irritating to the skin.

It is a fault of the present invention ( Cassia obtusifolia L .: 決 明) Seeds, means a seed that brightens the eyes. Cassia has an unusual smell and taste, weakness is sweet, bitter, salty, slightly cold. Hepatic (肝火) down the eyes are red, swollen, painful, tears flowing symptoms to treat, night blindness is used in the large intestine fever constipation effect is effective. In the present invention, the seed of the obscurity was used.

In the present invention, the deficiency extract may be extracted by solvent extraction. Solvent extraction can be carried out with a variety of extraction solvents, for example water, anhydrous or hydrous lower alcohols having 1 to 4 carbon atoms (eg, methanol, ethanol, propanol and butanol), propylene glycol, 1,3-butylene glycol, glycerin , Acetone, diethyl ether, ethyl acetate, butyl acetate, dichloromethane, chloroform, hexane, and mixtures thereof, which can be obtained using one or more extraction solvents, preferably ethanol, 70% (v / v) obtained using ethanol or water, most preferably obtained using 70% (v / v) ethanol.

On the other hand, it will be apparent to those skilled in the art that extracts having substantially the same effects can be obtained by using not only the aforementioned extraction solvent but also other extraction solvents.

According to one embodiment of the present invention, the deficiency extract can be extracted by supercritical fluid extraction or ultrasonic extraction.

Supercritical fluids have the properties of liquids and gases when the gas reaches a critical point at high temperature and high pressure and have a polarity that is chemically similar to a nonpolar solvent. Supercritical fluid extraction is an extraction method that extracts fat-soluble substances using supercritical fluids using these properties of supercritical fluids (J. Chromatogr. A. 1998; 479: 200-205).

Carbon dioxide becomes a supercritical fluid with both liquid and gaseous properties as the pressure and temperature reach the critical point by the operation of the supercritical fluid equipment, resulting in increased solubility in fat-soluble solutes. When supercritical carbon dioxide passes through an extraction vessel containing a certain amount of sample, the fat-soluble substance contained in the sample is extracted from the supercritical carbon dioxide.

After extracting the fat-soluble substance, the supercritical carbon dioxide containing a small amount of cosolvent is passed through the sample remaining in the extraction container to extract components that were not extracted with pure supercritical carbon dioxide alone.

The supercritical fluid used in the supercritical extraction method of the present invention can effectively extract the active ingredient by using a supercritical carbon dioxide or a mixed fluid in which a cosolvent is added to carbon dioxide.

The cosolvent may be used one or a mixture of two or more selected from the group consisting of chloroform, ethanol, methanol, water, ethyl acetate, hexane and diethyl ether.

Most of the extracted samples contain carbon dioxide. Since carbon dioxide is volatilized into air at room temperature, the extract obtained by the above method may be used as a cosmetic composition, and the cosolvent may be removed by a reduced pressure evaporator.

The ultrasonic extraction method is an extraction method using energy generated by ultrasonic vibrations. Ultrasonic waves can destroy insoluble solvents contained in the sample in aqueous solvents, and the high local temperature generated increases the kinetic energy of the reactant particles in the surroundings, thereby obtaining sufficient energy for the reaction. The impact effect of energy induces a high pressure to increase the mixing effect of the material and the solvent contained in the sample to increase the extraction efficiency.

As the extraction solvent that can be used in the ultrasonic extraction method, one or a mixture of two or more selected from the group consisting of chloroform, ethanol, methanol, water, ethyl acetate, hexane and diethyl ether can be used. The extracted sample may be vacuum filtered to recover the filtrate and then removed by a vacuum evaporator, and the extract may be obtained through a conventional extract preparation method of freeze drying.

Cassia extract according to the present invention, in addition to the extract extracted through the above-mentioned extraction method, also includes an extract extracted by further fermenting the extract. Specifically, finely crushed to about 100 to 500 mesh and then prepared by extracting the solvent extracted, supercritical extraction or ultrasonic extraction. It is added to the conventional microbial culture medium at 1-50g / L and microorganisms such as yeast strains or lactic acid bacteria are added in amounts of 10,000-100,000 cfu / L. The incubation temperature is incubated under the normal microbial culture conditions of 30 ~ 37 ℃. The pH is 5 to 7 incubated for about 5 to 10 days in aerobic or usually anaerobic conditions. It can then be obtained through aging and filtration.

In the above microorganisms may be lactic acid bacteria or yeasts. Preferably, the lactic acid bacterium was used as Lacobacillus bulgaricus , and Saccharomyces cerevisiae was used as the yeast.

The extract extracted by the above methods can be used in the cosmetic composition of the present invention by condensing at room temperature, liquid obtained by heat filtration, and further concentrated or freeze-dried a solvent.

According to the present invention, the RX complex blood is a combination of menthyl lactate, betaine salicylate, and the deficiency extract to determine the composition showing the optimum efficacy, and provides a cosmetic composition comprising the same.

The RX complex blood may include menthyl lactate, betaine salicylate, and the extract extract in a weight ratio of 1 to 3: 1 to 5: 1 to 5, and more preferably to include a weight ratio of 3: 5: 5: Can be.
