Description

Method for producing stick-type cosmetic composition

Technical Field

Disclosed herein are a method of manufacturing a stable stick cosmetic composition and a stick cosmetic composition manufactured using the same.

Background

Since stick type cosmetics are easy to use and excellent in portability, the range of application thereof is expanding in the fields of sunscreen cream, stick type foundation, etc., in addition to lipstick as a conventional stick type cosmetic.

However, stick type cosmetics are liable to be broken by external impact or application to the skin due to inherent limitations of ingredients of cosmetic compositions thereof. In order to compensate for such disadvantages, attempts have been made to increase the content of wax and the like in the cosmetic composition, but when the content of wax is increased, the strength of the dosage form is excessively increased, resulting in a decrease in skin spreadability and an unpleasant feeling to the user due to the inherent fragrance of wax and the like. Further, a stick-type dosage form in which a substance having excellent mechanical and physical properties is disposed in the center of the dosage form and a cosmetic composition is disposed on the outer periphery thereof has been disclosed, but this method does not solve the inherent limitations of the cosmetic composition, and thus there are problems that the cosmetic composition comes off from the center, and a part of the cosmetic composition is cracked and thus comes off.

Disclosure of Invention

Technical problem to be solved

An object of the present invention is to provide a method capable of uniformly dispersing various ingredients contained in a stick-type cosmetic composition.

Another object of the present invention is to provide a stick-type cosmetic composition which is not easily broken while maintaining a skin-applied feeling.

Means for solving the problems

The invention provides a method for preparing a stick-type cosmetic composition, which comprises the following steps: a first stabilization step of mixing 0.01 to 7 wt% of a clay mineral and 0.05 to 35 wt% of a first emollient, based on the total weight of the composition, to form a clay mineral dispersion; a second stabilization step of mixing 0.01 to 45 wt% of a moisturizing component and 0.01 to 10 wt% of a first surfactant to form a moisturizing component dispersion; and a step of adding the clay mineral dispersion and the moisturizing ingredient dispersion to the oily portion.

The present invention provides a stick-type cosmetic composition manufactured by the method.

ADVANTAGEOUS EFFECTS OF INVENTION

The method for producing a stick-type cosmetic composition of the present invention comprises a step of stabilizing the clay mineral dispersion and the moisturizing component separately, and thus can uniformly disperse the various components in the composition. The conventional stick-type composition is easily broken due to the phenomenon that various components are unevenly dispersed and the components in the dosage form are phase-separated, but the stick-type cosmetic composition manufactured by the method has an advantage that it is not easily broken while maintaining the sense of application and the sense of use.

Detailed Description

The present invention is described in detail below.

In the present specification, the terms "first" and "second" are used to distinguish between each component and each manufacturing step, and are not intended to limit the order of addition or mixing of the components and the order between the manufacturing steps.

The method for producing a stick-type cosmetic composition of the present invention comprises the steps of: a first stabilization step of mixing 0.01 to 7 wt% of a clay mineral and 0.05 to 35 wt% of a first emollient, based on the total weight of the composition, to form a clay mineral dispersion; a second stabilization step of mixing 0.01 to 45 wt% of a moisturizing component and 0.01 to 10 wt% of a first surfactant based on the total weight of the composition to form a moisturizing component dispersion; and a step of adding the clay mineral dispersion and the moisturizing ingredient dispersion to the oily portion.

According to the method for producing a stick-type cosmetic composition of the present invention, since the clay mineral and the moisturizing component are separately stabilized and then mixed with the oily portion including wax or the like, the clay component and the moisturizing component can be uniformly dispersed in the composition and are not easily broken. In particular, the stick-type cosmetic composition has a morphology property of being laterally elongated in one direction, and the components in the composition settle down in the height direction of the dosage form according to the law of stoke and are uniformly distributed in the composition, but when the composition contains a clay mineral, the viscosity of the composition increases and the settling rate of the components in the composition decreases. Further, the first and/or second stabilization steps of the present invention have the effect of reducing the sedimentation rate by uniformly dispersing the clay mineral and the moisturizing component in the composition and reducing the particle size of each of the clay mineral and the moisturizing component. The composition of the present invention can reduce the sedimentation rate of the ingredients in the composition, thereby minimizing the uneven distribution of the ingredients in the composition, minimizing the separation of the ingredients in the dosage form, and improving the fracture of the dosage form.

As described above, in the step of adding the clay mineral dispersion and the moisturizing component dispersion to the oil portion, the moisturizing component dispersion is further added after the clay mineral dispersion is added to the oil portion.

In particular, when the moisture-retaining component is a water-soluble substance, there is a problem in the stability of the dosage form due to the separation from the oil component, but in one embodiment of the present invention, the moisture-retaining component is first stabilized to be uniformly dispersed in the composition, so that the separation phenomenon of the dosage form can be minimized, and the phenomenon of the breakage of the dosage form can be improved.

In the aspect, the clay mineral may include 0.01 to 7 wt%, preferably, 0.03 to 6 wt%, and further preferably, 0.05 to 5 wt%. When the content of the clay mineral is less than 0.05 wt% based on the total weight of the composition, the clay mineral cannot stably interact with the moisture-retaining component, and the moisture-retaining component may coagulate to collapse the stick formulation. When the content of the clay mineral exceeds 5% by weight, the stick-type cosmetic composition may be dry and astringent in use, resulting in a low moisture retention.

In such aspects, the first emollient may comprise 0.05 to 35 wt%, preferably 0.3 to 30 wt%, and more preferably 0.25 to 25 wt%, based on the total weight of the composition.

Also, in the aspect, the first emollient may include 300 to 1000 parts by weight based on 100 parts by weight of the total weight of the clay mineral. When the first emollient is less than 300 parts by weight based on 100 parts by weight of the total weight of the clay mineral, uniform dispersion of the clay mineral in the composition may not be achieved, thereby decreasing the stability of the dosage form. The first emollient is preferably included in an amount of 500 to 1000 parts by weight, based on 100 parts by weight of the clay mineral.

In this aspect, the first emollient may include caprylic capric triglyceride, but is not limited thereto.

In the aspect, the moisture retention component may be included by 0.01 to 45 wt%, preferably 0.05 to 40 wt%, and further preferably 0.1 to 35 wt%, based on the total weight of the composition. When the content of the moisturizing ingredient is less than 0.1% by weight, the moisturizing power of the cosmetic composition may be significantly reduced, and when it exceeds 35% by weight, a separation phenomenon occurs in the dosage form to deteriorate the dosage form stability of the cosmetic composition.

In the aspect, the moisturizing ingredient is a water-soluble moisturizing ingredient. In one embodiment, the moisturizing component can include glycerin.

Also, in the aspect, the first surfactant may be included by 0.01 to 10 wt%, preferably 0.05 to 7 wt%, and further preferably 0.1 to 5 wt%, based on the total weight of the composition. When the content of the first surfactant is less than 0.1 wt%, the moisture-retaining components cannot be stably dispersed and emulsified, and thus a separation phenomenon occurs. If the amount exceeds 5% by weight, the moisturizing components do not finely disperse and coagulate with each other, and thus the moisturizing components cannot be uniformly dispersed in the cosmetic composition. For example, if the content of the first surfactant exceeds 5% by weight, the average particle size of the moisturizing component-containing substance will exceed 10 μm, and the moisturizing component will not be uniformly dispersed in the composition.

The moisture-retaining component-containing substance in the present specification may include a substance containing only a moisture-retaining component and a substance containing other components than the moisture-retaining component.

The average particle diameter in the present specification means an average value of lengths of 2 axes measured at an arbitrary point of a diameter of a particle divided by an axis having the longest length and an axis having the shortest length.

In such aspects, the first surfactant can comprise cetyl olive oil, sorbitol olive oil, or mixtures thereof.

In one embodiment, the clay mineral may comprise a platy mineral. Specifically, the plate-like mineral may include montmorillonite. The smectite may comprise hectorite or bentonite, and preferably, may be hectorite. In one embodiment, when the clay mineral is hectorite, the various components in the stick-type cosmetic composition are most uniformly dispersed, and the physical strength of the stick-type cosmetic composition is most excellent.

In one embodiment, the clay mineral may be selelonium hectorite.

Also, in the aspect, the first stabilizing step may include stirring the clay mineral and the first emollient at 1000 to 2500rpm, preferably 1500 to 2000 rpm. When the stirring speed of the first stabilization step is less than 1000rpm, the clay mineral cannot be sufficiently swelled in the first emollient agent to obtain the viscosity required for manufacturing a stable dosage form. When the stirring speed in the first stabilization step exceeds 2500rpm, excessive air bubbles are generated in the composition, and the stability of the dosage form is lowered.

Also, in the aspect, the second stabilizing step may include a step of mixing the moisturizing ingredient with the first surfactant at 60 to 90 ℃. The temperature of the second stabilization step is preferably 75-85 ℃. When the temperature of the second stabilization step is less than 60 ℃, the solid surfactant cannot be dissolved, and when the temperature exceeds 90 ℃, the components in the composition are thermally deformed or volatilized to disappear.

In one embodiment, the oily portion is formed by mixing 5-40 wt% of wax, 0.01-10 wt% of a second surfactant and the balance of a second emollient, based on the total weight of the composition.

In one embodiment, the oily portion may further comprise a lipid-like substance or a preservative. The lipid-like material may be included in an amount of 1 to 5 wt%, preferably 2.5 to 3.5 wt%, based on the total weight of the composition. The lipid-like substance may be mango butter, shea butter, cocoa butter or jojoba butter (jojoba butter), but is not limited thereto.

And, the preservative may be included by 0.03 to 1.5 wt%, preferably, 0.05 to 1.3 wt%, based on the total weight of the composition. The preservative may be ethylhexyl glycerin or 1, 2-hexanediol, but is not limited thereto.

In the aspect, the wax may be included by 5 to 40 wt%, preferably 6 to 35 wt%, and further preferably 10 to 30 wt%, based on the total weight of the composition. When the content of the wax is less than 10% by weight based on the total weight of the composition, it is difficult to form a stick-type dosage form, and when it exceeds 30% by weight, the strength is too high, which may reduce the coating feeling, particularly the coating feeling of lips.

In the aspect, the wax may include one or more selected from the group consisting of carnauba wax, candelilla wax, propolis wax, ozokerite wax, microcrystalline wax, and beeswax, but is not limited thereto.

Also, in the aspect, the second surfactant may include 0.01 to 10 wt%, preferably 0.05 to 8 wt%, and further preferably 0.1 to 7 wt%. When the content of the second surfactant is less than 0.1% by weight, the components in the composition cannot be stably and uniformly dispersed and emulsified, and when it exceeds 7% by weight, the separation phenomenon of the formulation occurs.

In the aspect, the second surfactant may include Cetyl PEG/PPG-10/1 Dimethicone (Cetyl PEG/PPG-10 Dimethicone) or olive oil sorbitol, but is not limited thereto.

In the aspect, the second emollient may include one or more selected from macadamia nut oil, pentaerythritol tetraisostearate, and caprylic capric triglyceride, but is not limited thereto.

Another aspect of the present invention is a stick cosmetic composition made by the method.

The cosmetic composition may be a lip composition. Lip sticks having a proper coating feel are difficult to produce due to the structural specificity of the lips themselves (for example, structures such as large volume due to a large area and no bones inside the lips). The stick-type cosmetic composition according to an aspect of the present invention has an advantage in that it can maintain an optimal application feeling when applied to the lips and is not easily broken.

The stick cosmetic composition may be for lip makeup, lip moisturizing or skin makeup. For example, the stick type cosmetic composition may be a lipstick or a lip gloss, but is not limited thereto. The skin makeup composition may include, but is not limited to, a stick-type sunscreen cream, a stick-type foundation, a stick-type cleanser, and the like.

The structure and effects of the present invention will be described in more detail by examples and experimental examples. However, these examples and experimental examples are only used as examples to assist understanding of the present invention, and the scope of the present invention are not limited to the following examples.

EXAMPLE 1 production of stick-type cosmetic composition

[ example 1-1] stabilization of Clay mineral

According to the total weight of the composition, 2 weight percent of selamelonium hectorite and 10 weight percent of caprylic/capric triglyceride are stirred in a high-speed stirrer at 1500-2000 rpm for 30 minutes, and firstly, the clay mineral is dispersed and stabilized to the emollient.

[ examples 1-2] stabilization of moisturizing ingredient

The glycerin is dispersed and stabilized by dissolving 10 wt% of glycerin and 3 wt% of olive oil cetyl ester/olive oil sorbitol at 75-85 ℃ based on the total weight of the composition, and emulsifying in a high-speed mixer.

Examples 1 to 3 production of oily portion and production of stick-type formulation

The components listed in Table 1 below were mixed at 80 to 85 ℃ to prepare an oily portion. Thereafter, the stabilized clay mineral of example 1-1 was added to the oil portion, and stirred and dispersed by a high-speed stirrer.

Thereafter, the stabilized glycerin-olive oil cetyl ester/olive oil sorbitol of example 1-2 was added and stirred and dispersed again by a high speed stirrer to manufacture a composition. Thereafter, the composition is finally produced by removing air bubbles from the composition and filtering impurities, and the composition is produced into a stick-type dosage form.

[ TABLE 1]

Experimental example 1 measurement of physical Properties of stick-type dosage forms

Tests for feeling of use (softness, moisture retention duration, and formulation stability) were conducted for 50 women and 50 men. Lips were washed with water and dried using the stick type water prepared in example 1, and then 0.1g was applied thereto, and after 1 minute, the feeling of use was evaluated. The forming stability was evaluated for breaking, clumping or formulation stability at the time of lip application. The evaluation score was 5 to 1, the feeling of use was excellent, 5 and very poor, 1, and the average of the total of the test scores was calculated. The results are shown in Table 2.

Comparative example 1 comparison with stick-type dosage forms that had not undergone a stabilization step

Comparative example 1-1 stabilization of clay mineral and stabilization of moisture-retaining component

In comparison with the stabilization step of example 1, the same ingredients as in example 1 were simultaneously mixed to manufacture a general stick type dosage form, except that the clay mineral and the surfactant were not used. The general stick type dosage forms were also subjected to the feeling of use test in the same manner as in experimental example 1, and the results are shown in Table 2.

[ TABLE 2]

As shown in table 2, the rod dosage form of the present invention subjected to the stabilization step was substantially more excellent in feeling of use than the ordinary rod dosage form not subjected to the stabilization step, and particularly, was excellent in molding stability by about 2.5 times or more (fig. 2).

Comparative examples 1-2 stabilization of clay mineral, but stabilization of moisture-retaining component was not performed

A stick-type formulation was prepared in the same manner as in example 1, except that the stabilization of the moisturizing ingredient was not performed as described in example 1-2. Thereafter, physical properties of the stick type dosage forms were measured in the same manner as in experimental example 1, as shown in Table 3. In this case, the physical stability of the stick was greatly reduced due to the precipitation of glycerol (fig. 3).

[ TABLE 3]

Comparative examples 1 to 3 where stabilization of the clay mineral was not performed, but stabilization of the moisture-retaining component was performed

In comparison with the description of example 1-1, a stick type dosage form was manufactured in the same manner as in example 1, except that the stabilization process of the clay mineral was not performed. Thereafter, physical properties of the stick type dosage forms were measured in the same manner as in experimental example 1, as shown in Table 4. In this case, the physical stability of the stick is greatly reduced due to the precipitation of glycerol. The side of the stick dosage form at this point is shown in FIG. 3.

[ TABLE 4]

Comparative example 2 physical Properties of stick type dosage form according to production sequence

Comparative example 2-1

Unlike example 1,2 wt% of selatonium hectorite, 10 wt% of caprylic/capric triglyceride, and 3 wt% of olive oil cetyl ester/olive oil sorbitol were simultaneously added to the oil portion, and then 10 wt% of glycerin was added to manufacture a stick-type dosage form. Thereafter, the physical properties of the stick-type dosage form were measured according to the method described in experimental example 1. In this case, the physical stability of the stick was also greatly reduced because glycerol was not stabilized (fig. 4).

[ TABLE 5 ]

Comparative examples 2 and 2

Stick type dosage forms were manufactured in the reverse order of comparative example 2-1 and tested in the same manner as in experimental example 1, and the results are shown in Table 6. In this case, the dosage form is too soft, and the components in the dosage form are unevenly dispersed in the height direction of the stick-type dosage form, thereby greatly decreasing the physical stability of the stick. The profile viewed from the side is almost similar to that of fig. 4.

[ TABLE 6 ]

Comparative example 3 physical Properties of stick type dosage form according to the content of ingredients

Table 7 below shows the results of table 8, in which stick-type dosage forms were manufactured by adjusting the contents of the respective components and the physical properties thereof were measured.

[ TABLE 7 ]

[ TABLE 8 ]

Comparative example 4 evaluation of physical Properties of stick-type dosage form according to production conditions

Comparative example 4-1 results according to the temperature at the time of mixing glycerin and olive oil cetyl ester/olive oil sorbitol

Using the mixing temperature of 58 ℃ as comparative example 4-1a, and 91 ℃ as comparative example 4-1b, a stick type dosage form was manufactured and the physical properties were measured.

As a result, in the case of comparative example 4-1a, it was difficult to complete the stick-type dosage form because glycerin and olive oil cetyl ester and the like were not dissolved, and in the case of comparative example 4-1b, the physical properties were almost the same as those of example 1.

Comparative example 4-2 evaluation of physical Properties of stick-type formulation based on temperature at the time of production of oil portion

The temperatures at the time of producing the oily portions were set to 50 ℃, 68 ℃, 86 ℃ and 90 ℃, and these were named as comparative examples 4-2a, 4-2b, 4-2c and 4-2d, respectively. Thereafter, the physical properties were evaluated in the same manner as in experimental example 1.

As a result, 4-2a and 4-2b, which have a mixing temperature of less than 70 ℃, do not form a stick form because wax components and the like are not sufficiently dissolved, and when they exceed 90 ℃, a stable stick form cannot be formed.
