Description

Water-in-water cosmetic composition comprising an outer emulsion layer {OIL-IN-WATER TYPE COSMETIC COMPOSITIONS WITH OUTER EMULSION LAYER}

The present invention relates to an oil-in-water cosmetic composition having excellent durability and water saving effect.

Formulations of conventional cosmetic compositions are classified into water-in-water type or water-in-oil type.

In general, a water-in-oil cosmetic composition has an advantage in that oil forms an outer layer, so that the cosmetic composition has a soft feel and excellent durability. However, the oil contained in the water-in-oil cosmetic composition is not easily removed from the skin, and the user needs to thoroughly clean the used area after using the water-in-oil cosmetic composition. For example, in order to clean glyceride, which is one of the oil components, it is necessary to use a detergent having strong cleaning power and an excessive amount of water. Cleaning components generated in this process cause environmental pollution, and since a large amount of washing water is required for cleaning, there is a limit in terms of sustainable development.

On the other hand, the water-in-water cosmetic composition has the advantage that water forms an outer layer, so that the cosmetic composition has a fresh feeling of use and is easy to clean. However, in the water-in-water cosmetic composition, the water layer is at the outermost layer, so it is light and refreshing when applied to the skin, and provides a feeling of bursting when applied, but has limitations in durability and coverage compared to water-in-oil cosmetic compositions.

Development of new technologies to solve environmental pollution, water shortage, and waste problems has been in progress for a long time in various industrial fields, and it is necessary to actively cope with these environmental factors in the cosmetics field.

The water-in-water cosmetic composition of the present invention includes an aqueous phase as an external phase and an oil phase as an internal phase, and the aqueous phase includes a wax emulsion layer formed on the outside.

In the present invention, the wax emulsion layer contributes to improving the formulation stability of the aqueous phase of the water-in-water cosmetic composition and increasing the durability of the composition after application to the skin. In addition, the wax emulsion layer protects the outer surface of the aqueous phase of the composition to help the composition maintain moisturizing power.

In the present invention, the wax emulsion layer may be derived from an emulsion prepared by emulsifying wax.

In the present invention, the wax emulsion can be prepared by warming purified water and slowly melting it into an emulsifier, wax, and polyol. At this time, the temperature at which the purified water can be heated is preferably about 80 to 86° C., which is a temperature at which most plant-based waxes can be melted.

This wax emulsion is cooled to about 45° C. after the emulsification process is finished and added to the water-in-water raw material as a post-addition process to coat the outermost water phase. The wax emulsion layer forms a film on the outermost layer of the oil-in-water formulation, thereby enhancing durability in the water phase, increasing gloss, protecting from external stimuli and enhancing adhesion, and increasing detergency, enabling cleansing with light cleansing there is

In the present invention, the wax included in the wax emulsion layer may include natural and synthetic waxes. For example, Carnauba Wax, Candelila Wax, Hydrogenated Castor Wax, Bayberry Wax, Alpha Wax, Olive Wax, At least one wax selected from the group consisting of Ouricury Wax, Bees Wax, Cerabellina Wax, and Marine Wax may be used.

In particular, it is preferable to include plant-based wax as the wax. Plant-based waxes are highly compatible, have excellent gloss, can smooth the surface and provide moisturizing power, and are therefore preferably included in the wax emulsion layer of the present invention. As plant-based waxes, carnauba wax, candelilla wax, olive wax, jojoba oil wax, etc. may be used. In particular, carnauba wax composed of esters, hydroxycinnamic acid, hydroxycarboxylic acid, and fatty acids is It is more preferable because it has good compatibility with the aqueous phase and the oil phase.

In the present invention, the wax emulsion is preferably included in an amount of 0.1% by weight or more and less than 6% by weight of the total composition of the oil-in-water cosmetic. When the wax emulsion is included in an amount of less than 0.1% by weight, there is a problem in that desired efficacy cannot be obtained. If the wax emulsion is included at 6% by weight or more, the feeling of use becomes stiff, and the wax crystals form a high surface hardness, so that the surface of the formulation becomes hard and the inner hardness is not formed, so the inside is depressed when pressed and the discharge is not good. Occurs.

The oil-in-water cosmetic composition of the present invention may further include a second film therein. Preferably, the second film may be formed as a part of the oil phase or formed at the interface between the water phase and the oil phase.

Thus, by forming the second film on the inner coat, the moisturizing power is maintained through the oil phase, which is the inner coat, and the effect of enhancing durability and adhesion is provided, and there is an effect of reducing the color difference between the outer and inner colors by strengthening the dispersion of pigments.

In the present invention, for the formation of the second film, the composition may include a film forming agent. Illustratively, the film forming agent is an acryl-silicone graft selected from trimethylsiloxysilicic acid, (alkyl acrylate/dimethicone) copolymer, (acrylates/ethylhexyl acrylate/dimethicone methacrylate) copolymer, and the like. white copolymers; a silicone-based film forming agent selected from polymethylsilsesquioxane, polyphenylsilsesquioxane, and the like; And butyl acrylate/hydroxypropyl dimethicone acrylate copolymer (Butyl Acrylate/Hydroxypropyl Dimethicone Acrylate Copolymer), Acrylates Copolymer, Acrylates/C12-22 Alkyl Methacrylate Copolymer (Acrylates/C12- 22 Alkyl Methacrylate Copolymer, Ammonium Acrylates Copolymer, Styrene/Acrylates/Ammonium Methacrylate Copolymer, Methacryloylethyl Betaine/Acrylates Copolymer (Methacryloyl Ethyl Betaine/Acrylates Copolymer), Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer and Acrylates/Polytrimethylsiloxymethacrylate Copolymer (Acrylates/Stearyl Acrylate/Dimethicone Methacrylate Copolymer) Polytrimethylsiloxymethacrylate Copolymer) may be at least one compound selected from acrylate-based film forming agents.

In particular, among the silicone-based film forming agents, T resin is more preferably the above-described MQ resin in that it may affect formulation stability, and it is also preferable to use an acrylate film forming agent.

On the other hand, in the exemplary oil-in-water cosmetic composition of the present invention, the film former may be included in a range of greater than 0.1% by weight and less than 10% by weight based on the total weight of the composition. If it is less than 0.1%, the desired effect cannot be obtained, and if it is more than 10%, the internal wound becomes stiff and the boundary between internal and external wounds collapses.

On the other hand, in the exemplary oil-in-water cosmetic composition of the present invention, the water phase and / or oil phase may include a pigment, and it is preferable to include both the water phase and the oil phase.

When the pigment is dispersed only in the aqueous phase, the pigment exists only in the outer phase, and only the pigment remains on the surface after the water volatilizes. Therefore, the difference between the initial application color and the color expressed when time elapses after application is large, which can cause darkening. .

In addition, when the pigment is dispersed only in the oil phase, since the amount of oil in the inner phase must be increased as the amount of the pigment added increases, the emulsifying power of the oil-in-water formulation is lowered, thereby adversely affecting formulation stability.

In the present invention, the first pigment included in the aqueous phase may include at least one selected from titanium dioxide, yellow iron oxide, red iron oxide, and black iron oxide, and the first pigment is a dispersed pigment dissolved in polyol, It is a pigment obtained by mixing and dispersing a pigment with a polyol (glycerin, butylene glycol, dipropylene glycol, etc.) and a dispersing agent (sorbitan sesqueoleate, sorbitan isostearate, polyhydroxystearic acid, etc.) it is desirable In the entire composition of the present invention, the first pigment is preferably included in an amount of 0.1% to 50% by weight.

In addition, the present invention may include a second pigment in the oil phase. At this time, the second pigment may include at least one selected from titanium dioxide, yellow iron oxide, red iron oxide, and black iron oxide. The second pigment is a coating pigment, and the above-mentioned pigment is alumina, stearic acid, aluminum hydroxide, polyhydroxy stearic acid, polypropylsilsesquioxane, triethoxycaprylylsilane, lauro It is preferably a pigment coated with at least one coating material selected from lysine, silica, sodium lauroyl glutamate, and lysine. For example, the second pigment may be prepared by spraying the above-described coating material at a high temperature in a dry or wet manner on the surface of the pigment to cover the outer surface. In the total composition of the present invention, the second pigment is preferably included in an amount of 0.1 to 25% by weight.

When the pigment is included in both the water phase and the oil phase, the emulsifying power is improved and the dispersion is stabilized, and darkening can be reduced by reducing external and internal color changes.

In the composition of the present invention, the aqueous phase may be included in 45 to 80% by weight based on the total weight of the composition, and the oil phase may be included in 15 to 40% by weight based on the total weight of the composition.

When the oil phase is included in less than the above weight %, there is a concern that the durability of the oil-in-water cosmetic composition is significantly insufficient. Conversely, when the oil phase is included in excess of the above weight %, the washability of the oil-in-water cosmetic composition may be reduced due to the excessive content of the oil phase.

Hereinafter, the present invention will be described in more detail through drawings and examples. However, these drawings and examples are for illustrating the present invention by way of example, and the scope of the present invention is not limited by these drawings and examples. Also, unless otherwise stated herein, component content is in weight percent.

Then, after cleaning the application area in various ways, the application area was photographed again and compared with before cleaning. Each cleaning method is as follows. The flow rate at the time of rolling was 80 ml/.

(i) Washing by rolling 30 times with water

(ii) Washing by rolling 30 times with water and soap

(iii) Washing while rolling 30 times with water and foam cleanser

Figure 3 is a photograph showing the washability evaluation results of the oil-in-water cosmetic composition (Example 1) and commercial water-in-oil products according to this test example. Areas A, B, C, and E in the drawings correspond to areas where a commercially available product is applied, respectively, and area D corresponds to an area where Example 1 is applied. The cosmetics used in A, B, C, and E are water-in-oil type, and the water-in-oil cosmetic compositions of A, B, and C contain a film forming agent, but the type and content of the film forming agent are very different from those of the present invention, In the case of E, it is a water-in-oil cosmetic composition and corresponds to a product that does not contain a film forming agent.

Referring to FIG. 3, all five compositions showed the same contrast before washing with water, but the composition of Example shows excellent detergency compared to other commercial products even by simple cleaning, such as rolling 30 times of water cleaning, and soap cleaning or foam It can be seen that it shows excellent detergency to the extent that it can be completely removed by cleanser cleaning.

4. Water Savings Assessment

(1) Evaluation and comparison of water consumption during cleaning of the production line

Based on the commercial water-in-oil cosmetic composition and the cosmetic composition of this example (Example 1) at the time of production of 1 ton each, the amount of water consumed when washing the residue immediately after production was measured.

As a commercial water-in-oil cosmetic composition, for a composition that does not contain a film former, first (i) 500 kg of water is used to remove residues and wash with a detergent, (ii) 500 kg of water is used to remove insufficient parts and Remnants were removed and washed. Then, (iii) after disinfection and washing using 500 kg of water, it was confirmed that the residue was removed and the washing was completed. Therefore, it can be seen that a total of 1500 kg of water is consumed.

On the other hand, in the case of the water-in-water cosmetic composition of Example 1, (i) using 500 kg of water to remove residues and washing with high-temperature purified water, and then (ii) disinfecting and washing with 500 kg of water to achieve cleaning. It's done. Therefore, it can be seen that a total of 1000 kg of water is consumed.

In conclusion, it can be seen that the water-in-water cosmetic composition of Example 1 can save water by 33% per ton of production.

(2) Evaluation and comparison of water consumption when washing after makeup on the skin

When washing after applying the cosmetic composition to the skin to make up, the amount of water consumed was measured.

After applying about 0.5 ml of the cosmetic composition to the artificial skin, the amount of water consumed was measured when washing once, and a flow rate of about 80 m/s was applied.

As a commercially available water-in-oil cosmetic composition, in the case of a composition not containing a film former, it was confirmed that washing took 3 minutes and consumed about 15 L of water. In the case of the water-in-water cosmetic composition of Example 1, it was confirmed that washing took 2 minutes and consumed about 10 L of water.

Therefore, it was confirmed that the water-in-oil cosmetic composition of Example 1 could save 33% of the amount of water required for washing compared to the water-in-oil cosmetic composition. As a result, it can be seen that about 5L of water is saved per 30ml of product, since it is used about 70 times on average based on 30ml of product.
