Description

Cosmetic composition containing beads and a method of manufacturing {{Cosmetic composition containing amorphous beads and method}

The present invention relates to a cosmetic composition and a manufacturing method containing the beads, the cosmetic composition of the present invention can provide a moisturizing effect and visual differentiation of the skin.

Skin protects the body from external physical and chemical stimuli. However, as the moisture content of the stratum corneum decreases due to changes in the environment, pollution, and natural skin aging due to various stresses, the function of the skin barrier is lost. Therefore, the importance of moisturizing skin as a solution to this problem is increasing.

The general emulsion type formulations tend to exhibit moisturizing effects, but the solubilization or gel type formulations do not easily show good moisturizing effects because of the relatively low oil phase content. In particular, the occlusive effect by the oil film is more difficult to show. Therefore, gel-type formulations are gaining great popularity among consumers for their clean appearance and fresh feeling, but they show limitations for this problem.

Recently, with increasing interest in beauty, cosmetics having various ingredients and effects have been released. In addition, as products that are differentiated from conventional formulations are released, efforts for visual change as well as efficacy are increasing.

For example, adding capsules or beads to clear formulations not only provides a gorgeous aesthetic, but also allows for a high-quality image. Such additives are separately prepared and added to the formulation, which is not only cumbersome but also difficult to manufacture.

The technology known as bead cosmetics is a pack cosmetic known in Korea Patent Publication No. 10-2009-0069741, but is a technology specialized in pack products.

Therefore, the inventors of the present invention have attempted to develop a cosmetic composition that provides a moisturizing and softening effect to the skin while producing beads in the formulation while providing simple and visual differentiation. It is therefore an object of the present invention to provide a cosmetic composition containing beads having a moisturizing effect on the skin.

In order to achieve the above object, the present invention provides a cosmetic composition containing a suspension of vegetable butter, higher alcohol, and silicone elastomer powder.

Preferred compositions of the present invention are 1.0 to 20% by weight polyhydric alcohol, 0.2 to 1.0% by weight gelling agent, 1.0 to 5.0% by weight vegetable butter, 0.5 to 2.5% by weight higher alcohol, 3.0 to 20% by weight suspension of silicone elastomer powder Contains.

The preparation method of the present invention is a first step of dissolving a polyhydric alcohol in purified water warmed to 50 ℃ and dissolving the gelling agent in an aqueous phase while stirring with an Agi mixer.

A second step of warmly dissolving butter and a higher alcohol and injecting it into the first step while stirring with an Agi mixer; And

Hereinafter, the present invention will be described in detail.

The cosmetic composition containing the beads according to the present invention comprises suspensions of vegetable butter, higher alcohols, and silicone elastomer powders as main components, and further contain polyhydric alcohols and gelling agents.

The polyhydric alcohol used in the present invention may be glycerin, butylene glycol, propylene glycol, dipropylene glycol, polyethylene glycol, propanediol and the like, and contains 1.0 to 20.0% by weight based on the total weight. If it is less than 1% by weight, the moisture is less, and if it exceeds 20% by weight, it is not suitable because it feels wet and sticky of polyhydric alcohol.

The gelling agent used in the present invention is sodium polyacrylate, carbomer, acrylate / C10-30 alkyl acrylate crosspolymer, ammonium acryloyl dimethyl taurate / V-Picopolymer, hydroxyethyl acrylate / sodium acrylo Ylmethyltaurate copolymer and the like, with sodium polyacrylate being preferred. It contains 0.2 to 1.0% by weight based on the total weight. If it is less than 0.2% by weight, the viscosity is too low to form beads, and if it is more than 1.0% by weight, the viscosity is too high.

Vegetable butter used in the present invention may be shea butter, mango seed butter, cocoa seed butter, cacao seed butter and the like, and contains 1.0 to 5.0% by weight relative to the total weight. If it is less than 1% by weight, the amount of beads is small, and if it is more than 5% by weight, it is not suitable because a wet feeling of oily ingredient is felt.

The higher alcohol used in the present invention may be cetearyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol and the like, and contains 0.5 to 2.5% by weight based on the total weight. If it is less than 0.5% by weight, the amount of beads decreases, and if it exceeds 2.5% by weight, the waxy feeling peculiar to higher alcohols is felt, which is not suitable. Preferably the ratio of butter to higher alcohol is 2: 1. If the ratio of butter exceeds 2: 1, it feels damp. If the ratio of high alcohol is high, the beads are not easily broken and irritate, which is not suitable.

The suspension of the silicone elastomer powder used in the present invention is a phase obtained by Dow Corning as a suspension in which the dimethicone / vinyldimethicone crosspolymer is dispersed in purified water by C12-14Palace-12 under the trade name BY29-119. Use supplies. It contains 3 to 20% by weight of the total weight, and less than 3% by weight can not neutralize the waxy feeling of the beads, and when it exceeds 20% by weight, the unique feel of the raw material becomes stronger and the transparent wound becomes opaque white. It is not suitable because it is not noticeable.

 The cosmetic of the above composition containing the beads according to the present invention is prepared by the following method.

1) The polyhydric alcohol is dissolved in purified water warmed to 50 ° C., and the gelling agent is dissolved in an aqueous phase while stirring with an Agi mixer (first step).

In addition, Comparative Example 4 was not formed beads to become a transparent gel phase did not show the characteristics of the beads. Therefore, the beads were found to be formed only when the suspension of shea butter, cetearyl alcohol and silicone elastomer powder is properly formulated, the appearance of the examples in which they are properly formulated the best results.

From Table 2, the embodiment of the cosmetic composition containing the beads according to the present invention showed the highest satisfaction with the feeling. In the case of the examples, the beads were naturally broken as rolling and exhibited a moist and soft feeling. On the other hand, Comparative Example 1 was irritating because the beads were not easily broken, and Comparative Example 2 was well cracked but exhibits a wet feeling. In Comparative Example 3, the oil film suddenly felt burdened during the initial watery. In Comparative Example 4, there was no bead and only watery feeling appeared. Therefore, the suspension of shea butter, cetearyl alcohol and silicone elastomer powder should be properly formulated to show the best usability and the result was also the best.

From Table 2, it can be confirmed that the embodiment of the cosmetic composition containing the beads according to the present invention had a high satisfaction in appearance and usability.

<Skin irritation test of Examples and Comparative Examples>

The skin irritation of Example 1 and Comparative Examples 1 to 4 prepared above was evaluated.

In order to test the skin irritation of the cosmetics, a patch test was conducted using a Haye's Test Chamber in 20 healthy adults and men. Wipe the test site with 70% ethanol and dry it, and then place a sealed patch (Finn chamber, 100 × 10, EPITEST, Finland) on the inside of the forearm of the test subject. It was. The patch was applied for 24 hours, the patch was removed, and the test site was marked with a marker pen. 1 hour and 24 hours after each removal (1 hour after removal, 24 hours = 24 hours, 48 hours including patch attachment) using a magnifying glass (8MC-150, DAZOR, United States of America) to observe the test site for erythema and edema Was observed. Skin response was determined according to the rules of the International Contact Dermatitis Research Group (ICDRG) (Table 3), the average skin reactivity was calculated by the following equation 1 and the results are shown in Table 4.

From Table 6, the Example of the cosmetic composition containing the beads according to the present invention was excellent in long-term storage stability. In Comparative Example 2, since the melting point of the shear butter is low, it is easily dissolved at a high temperature, and thus high temperature stability is not good. Therefore, it can be seen that the examples in which the suspension of shea butter, cetearyl alcohol, and silicone elastomer powder are properly formulated have no problem in long-term storage stability.

Moisturizing Effect of Examples and Comparative Examples

The moisturizing effect of Example 1 and Comparative Examples 1 to 4 prepared above was measured.

The cosmetics were applied twice a day to the upper arm and the moisturizing effect was measured using a Corneometer CM820PC (Courage + Khazaka, Germany) and Tewameter TM 210 (Courage + Khazaka, Germany). The corneometer was used to quantify the moisture content of the skin from 0 to 150 with the change of electrical conductivity according to the epidermal moisture content, and the Tewameter was used to measure the transdermal loss amount (TEWL), that is, the epidermal water loss. The test was conducted for 4 weeks, and the results were shown in Table 7 by using the apparatus at 2 and 4 weeks.

From Table 7, the embodiment of the cosmetic composition containing the beads according to the present invention was excellent in the moisturizing effect. In Comparative Example 4, the gel phase did not contain beads, and thus the oil-containing component was not contained. Therefore, the moisturizing effect was not large. Comparative Examples 1 to 3 showed a moisturizing effect because the oil phase component was contained to some extent, but did not show the same effect as the Example. Therefore, it was found that the Example has excellent moisturizing effect, and in particular, the amount of water loss, which is hard to appear in gel form, is greatly reduced.
