Description

The present invention relates to a cosmetic composition comprising a homogeneous particle of curd and a method for producing the same.

The present invention relates to a cosmetic composition comprising a uniform particle of curd and a process for its preparation.

It has long been known that milk has several cosmetic beneficial effects. Therefore, there have been many attempts to use milk or milk ingredients in cosmetics. For example, a method of adding milk to water or ethanol, which is the main base (solvent) of cosmetics, has been studied, but only a very limited amount has been used because of problems such as feeling, stability, and uniformity of particles, It has been common to manufacture and use cosmetics.

In order to solve such a problem, there has been an attempt to incorporate the defatted milk-derived cream into the external preparation for skin (Korean Patent Publication No. 10-2012-0075718).

However, attempts have not been made to make cosmetic compositions which form curd by adding acid to milk.

On the other hand, when acid is simply added to a cosmetic formulation containing milk, the curd due to protein coagulation is formed as the pH is lowered. The curd formed at this time is difficult to control the particle size distribution and particle size, Which is not suitable for cosmetics.

Under these circumstances, the present inventors conducted studies on the difference in acid addition method after preparing a milk-based formulation emulsion. When the diluted acid component is added slowly under a certain temperature condition, the emulsion particle size Was found to be small and evenly distributed, thereby completing a cosmetic composition having a smooth feeling of use.

The present invention also provides a method for producing a cosmetic composition comprising milk.

It is still another object of the present invention to provide a cosmetic composition comprising a uniform particle of curds prepared according to the above-described method.

In order to solve the above-mentioned problems and to achieve the object of the present invention, And water to a temperature of 70 to 80 占 폚 and mixing them; Cooling the mixture to 40 to 50 占 폚; And mixing the diluted acid with the mixture at 40 to 50 占 폚.

As another aspect of the present invention, there is provided a cosmetic composition comprising a uniform particle of a curd prepared according to the above-described production method.

Hereinafter, the present invention will be described in detail.

The present invention is based on the finding of a method for producing a cosmetic composition in which the particle size is small and uniformly distributed and the feeling of use is improved by changing the method of adding acid to milk.

Conventionally, in the case of simply adding an acid to milk, there is a problem that the curd formed by protein coagulation has a quality that is not suitable for cosmetics because of difficulty in controlling the particle size distribution and particle size.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for manufacturing a cosmetic composition with improved feeling by slowly adding an acid component diluted under a certain temperature condition.

In the present invention, (a) oil phase; And water to a temperature of 70 to 80 占 폚 and mixing them; (b) cooling the mixture to 40 to 50 占 폚; And (c) mixing the mixture with the diluted acid at 40 to 50 占 폚.

In the present invention, the step (a) may comprise: And milk are heated to 70 to 80 캜 and mixed therein. This is a pretreatment process for preparing a mixture of oil phase and water phase before adding curd to milk by adding an acid thereto.

In the present invention, the term " oil phase "means an oil phase-containing phase and" water phase "means an oil phase-containing phase. May be used without limitation. The mixing of the oil phase and the water phase may be carried out by specifically introducing the oil phase into the water phase.

The oil phase may further include at least one of an oil and an emulsifier.

The oil may be a polar oil, a non-polar oil or a mixture thereof.

The non-polar oil may be a silicone oil or a hydrocarbon oil, but is not limited thereto.

The silicone oil may be selected from the group consisting of dimethicone, lauryl dimethicone, cyclopentasiloxane, cyclohexasiloxane, trisiloxane, methyltrimethicone, phenylmethicone, dimethicone polyol, Dimethicone polyol acetate, silicone glycol copolyol, But are not limited to, cone, methylpolysiloxane, methylphenylpolysiloxane, dimethicone copolyol methyl ether, methylcyclopolysiloxane, dimethylpolysiloxane, hexamethyldisiloxane, or caprylylmethylpolysiloxane.

The hydrocarbon oil includes, but is not limited to, isododecane, isohexadecane, squalane, hydrogenated polyisobutene, vaseline, paraffin, ceresin, or mineral oil such as petrolatum.

The emulsifier may be selected from the group consisting of cetearyl alcohol, phage-100 stearate, sorbitan olivate, glyceryl stearate, lecithin, polyglyceryl-3 methyl glucoside distearate, phage-40 castor oil, polysorbate 60 And specifically may be cetearyl alcohol, glyceryl stearate, and / or phage-100 stearate, and more specifically may be cetearyl alcohol, but is not limited thereto.

The water phase may further comprise milk and a preservative. Specifically, in the present invention, milk may be contained in the water phase, and a curd may be generated by adding an acid diluted in the milk in a subsequent step. When the curd is produced according to the method of the present invention, it is possible to produce emulsified particles having uniform particle and very soft feeling.

Examples of the preservative include 1,2-hexanediol, propanediol, caprylylglycol, phenoxyethanol, ethylparaben, methylparaben and the like, and 1,2-hexanediol may be specifically used.

The term "milk" in the present invention means any dairy product derived from milk and milk such as raw milk, colostrum, milk, powdered milk, condensed milk, curdled milk, fermented milk, yogurt, whey, ice cream, fresh cream, butter, cheese and the like.

The oil phase and water phase can be heated to 70 to 80 ° C, specifically to 75 ° C, and the oil phase and the water phase can be easily mixed according to the heating. Specifically, emulsifiers and waxes contained in an oil phase can not exist in a liquid state at a low temperature, and therefore, when they are produced in a state in which they are not warmed up, emulsified particles of a certain size can not be produced. Therefore, uniform emulsified particles can be formed through the warming process.

The mixing step may be performed at 70 to 80 ° C. If the temperature is lower than 70 ° C, there may be a problem that the oil phase and the water phase are not mixed well, and if the temperature is higher than 80 ° C, there is a problem that the generated curd hardens hardly.

In the present invention, the step (b) is a step of cooling the mixture to 40 to 50 캜, which is a pretreatment process for producing a curd having uniform particle by adding an acid at a lower temperature.

In the above step, it is possible to cool to 40 to 50 ° C, specifically to 45 ° C.

The cooling may be performed at 40 to 50 < 0 > C. If the value is out of the above-mentioned range, there may be a problem that the particle size is not uniform and the feeling of use is deteriorated at the time of producing the curd by mixing the diluted acid.

The step (b) may further include a step of defoaming, in order to prevent the viscosity from increasing or decreasing beyond the expected value by influencing the viscosity measurement of the mixture when bubbles are present in the mixture.

In the present invention, "defoaming" may mean removing bubbles or bubbles.

The steps (a) and (b) are pre-processing steps for the acid addition step, which is an essential step of the present invention to be described later.

In the present invention, the step (c) is a step of mixing the mixture with the diluted acid at 40 to 50 ° C, and through this step, a curd having uniform particle size can be produced from the milk.

The temperature at which the acid is added in the above step may be 40 to 50 ° C, specifically 45 ° C. When the temperature is within the above temperature range, excellent effects can be obtained in terms of uniformity of particles and feeling of use. Specifically, when an acid is added and mixed at a temperature of 50 ° C or higher, uneven and large curd grains can be formed because the reaction rate with milk is increased, and when an acid is added and mixed at an excessively low temperature, The flowability of the emulsified particles deteriorates, which makes it difficult to evenly disperse the acid.

 In one embodiment of the present invention, it was confirmed that when the temperature at which the acid was introduced was 45 ° C, the particle uniformity and feeling of use were remarkably superior to those at 75 ° C (Table 3).

When an acid is added according to the production method of the present invention, the viscosity of the cosmetic composition is increased, and a small particle size and uniform curd can be produced. The step of adding the acid may be specifically carried out after emulsification.

In one embodiment of the present invention, when lactic acid diluted to 5% was added to purified water after emulsification of the oil phase and water phase, the granule size was more uniform than that of the case of feeding the lactic acid raw solution before emulsification 3).

In addition, the acid added in the present invention is preferably a diluted acid.

The acid may be 3 to 30% by weight and may be diluted in a solvent, specifically 5 to 10% by weight, and more particularly 5% by weight, in a solvent.

If the acid is less than 3% by weight and diluted in a solvent, there may be a problem that no curd is formed. If the acid is more than 30% by weight, a curd may not be generated uniformly,

In the embodiment of the present invention, it was confirmed that when the diluted acid of 5% was added to the purified water, the uniformity of the emulsified particles was remarkably improved and the feeling of use was better than when the lactic acid concentrate was directly added (Table 3).

In addition, the acid added in the present invention can be mixed in an amount of 0.01 to 1% by weight, more specifically 0.1 to 0.7% by weight, and more specifically 0.5% by weight, based on the whole cosmetic composition. In addition, the pH of the acid added in the present invention may be 1 to 5, and may be 2 to 4 in particular. A curd is formed within the pH range, and when the pH is more than 6, there is a fear that a curd is not formed. Here, the pH means the pH of the acid to be added to the mixture.

In the present invention, "acid" may be lactic acid, citric acid, fumaric acid, tartaric acid, succinic acid, maleic acid, malic acid, oxalic acid, ascorbic acid, aspartic acid, formic acid or glutamic acid and may be lactic acid, Do not.

The present invention may further include (d) cooling the mixture to 25 to 30 DEG C, and the cooling may further include defoaming.

This step can be cooled to 25 to 30 占 폚, specifically to 28 占 폚. This is to make the curd obtained by adding an acid diluted in milk to have more uniform particles and to have a good feeling of use. In addition, when the emulsified particles having uniform fluidity at high temperature are cooled to room temperature, the fluidity is reduced and can be stored for a long time in a stable state.

The defoaming step is to remove bubbles in order to prevent the viscosity from increasing or decreasing beyond the expected value by influencing the viscosity measurement of the mixture when bubbles are present in the mixture. In addition, in the case of a product manufactured through a defoaming process, the oil screen is further lustrous and smooth, and the stability of the particles over time can also be affected.

Curd can be produced by mixing diluted acid with the mixture. .

In the present invention, "curd" means that milk is solidified by an acid or an enzyme, and the main component of the curd is a coagulum of casein, which is a main protein of milk. Generally, milk can form curds through the coagulation of proteins and the like as the pH is lowered.

The curd may be a uniform particle.

The acid may be used to lower the pH of the milk to produce curd, a coagulated milk protein.

In another aspect of the present invention, there is provided a cosmetic composition comprising a uniform particle of curd prepared according to the process for producing a cosmetic composition as described above.

The viscosity of the curd may be 5000 to 7000 cps, and may be specifically 6100 cps. It is possible to provide a cosmetic composition excellent in feeling in the above viscosity range.

The particle size distribution of the curd may be from 2 to 9 vol% at 10 to 100 [mu] m.

"Particle size distribution" in the present invention may mean particle size distribution of curd produced by adding acid to milk.

The particle size of the curd may be 0.1 to 1000 [mu] m. It is possible to provide a cosmetic composition excellent in feeling in the particle size range.

The cosmetic composition according to the present invention can provide a cosmetic composition comprising a curd having a uniform particle size and a soft feeling by using a method of warming and cooling an aqueous phase containing milk and milk and adding diluted lactic acid have.

Meanwhile, the cosmetic composition according to the present invention can be used as a cosmetic composition in the form of a solution, an ointment for external use, a cream, a foam, a nutritional lotion, a softening water, a pack, a soft water, an emulsion, a makeup base, It may be formulated as a suspension, emulsion, paste, gel, lotion, powder, soap, surfactant-containing cleansing, oil, powder foundation, emulsion foundation, wax foundation, patch and spray, But is not limited to.
