Description

Multiphase Emulsion-type Latex Cosmetics and Manufacturing Method Thereof

The present invention relates to a multiphase emulsion emulsion cosmetic and a method for preparing the same, and more particularly, using a vitamin C derivative and a water-soluble polymer, a polyphase emulsion type, especially a W / 0 / W type oil, which has excellent stability and viscosity control. It relates to a liquid cosmetic and a method for producing the same.

The polyphase emulsion type emulsion phase refers to an emulsion phase having a multiemulsion structure. W / O / W type is a type in which water-in-oil (W / 0), which is a general emulsion type, is dispersed in the water phase again. At this time, the award dispersed in the oil award is called the domestic award, and the award dispersing the award is called the outward award.

The multiphase emulsion-like emulsion phase has been promoted for application to cosmetics or foods due to the unusual particle structure as described above, and the related invention has already been filed. (US Pat. No. 1,541,463, Japanese Patent Laid-Open No. 63-33311, No. 63-33316, No. 60-222412, No. 59-80326, No. 59-127646, No. 58-183611, No. 58-183612 Ho etc.).

However, the polyphase emulsion prepared in the prior art, first, since the inner and outer water phases are separated by a thin oil film, so that when the concentration difference occurs in the inner water and the outer water, osmotic pressure causes water to move. Oil film is easily destroyed, and secondly, since the particles are larger and more uneven than conventional W / O type or O / W type emulsified particles, coalescence occurs between the particles to separate the oil phase and the water phase. After the lipophilic emulsifier used to form the emulsified particles is prepared to form the W / O / W type emulsified particles, the lipophilic emulsifier moves to the interface of the outer water phase and threatens the stability of the emulsified system. It was difficult to maintain stable and it was difficult to obtain a good product appearance.

Accordingly, the present inventors earnestly researched to solve the above problems, and found that by using a vitamin C derivative and a water-soluble polymer, it was possible to prepare a multiphase emulsified emulsion cosmetic with stable viscosity control. It became.

That is, the present invention is to provide a multi-phase emulsion emulsion cosmetics excellent in stability and viscosity control and a method for producing the same.

Hereinafter, the present invention will be described in detail.

In the present invention, in the preparation of a multiphase emulsion-like emulsion cosmetic, 0.1 to 1.0 parts by weight of water-soluble polymer, 0.1 to 5.0 parts by weight of salt and 0.1 to 5.0 parts by weight of protein are mixed and dissolved in 10.0 to 70.0 parts by weight of purified water.

Prepare an oil phase component containing a W / O type emulsion, and 0.2 to 2.0 parts by weight of water-soluble polymer in 10.0 to 60.0 parts by weight of purified water Sum to provide a method of melting by the outer After preparing the aqueous phase component, the other an oil phase component containing the W / O type emulsion by dispersing eda aqueous phase component producing a multi-phase emulsion type cosmetic oil liquid.

In addition, the present invention is to provide a multiphase emulsion-type emulsion cosmetic prepared according to the above method.

Such a present invention will be described in more detail as follows.

According to the present invention, a salt, in particular L-ascorbic acid phosphate ester magnesium salt, is added to the aqueous phase component.

In general, inorganic salts such as magnesium sulfate and sodium chloride salts are used as salts in water-based components to salt lipophilic emulsifiers to inhibit the penetration of water into the interfacial adsorption layer and to prevent stability of coalescence in the external and aqueous phases to enhance stability. Although, in the present invention, L-ascorbic acid phosphate ester magnesium salt is used to exhibit the same effect as the inorganic salt as well as skin whitening, and moreover, vitamin C is encapsulated in the polyphase emulsified structure of the present invention to improve stability. Can be. Moreover, the sodium or potassium salt of koji acid can be used as a salt.

These salts are used in the amounts as defined above, but if used below the above range, the yield of the aqueous phase is lowered and the penetration of water at the interface is not suppressed, resulting in poor stability and insufficient skin whitening effect. When used more than the range, the moisture in the inner phase is too much, it is unstable even in a small shear (shear) and slightly higher temperature, so that the discoloration is severe and the viscosity is low, the stability is poor.

In the present invention, the water-soluble polymer is used as the water-based component.

The water-soluble polymer used in the water-based component according to the present invention reduces the fluidity of the water-resistant particles to reduce the movement of water due to osmotic pressure to maintain the thickness of the oil layer to improve the stability. As the water-soluble polymer, at least one selected from carboxyvinyl polymer, methyl cellulose, polyacrylic acid, syntan gum, carboxymethyl cellulose, hydroxyethyl cellulose and polyvinyl derivative is used.

These water-soluble polymers are used in the above-mentioned ranges. If the water-soluble polymers are used in the above-mentioned ranges, the viscosity of the water-soluble polymers is low and the fluidity of the W / O-type emulsifier becomes unstable. The yield is low because it is too high to give a lot of shear when dispersing.

In addition, in the present invention, the water-soluble polymer is also contained in the external water component, and the water-soluble polymer used in the external water component not only disperses the particles uniformly and uniformly, but also prevents aggregation and coalescence, so that the particles are uniform. It is excellent and also enables viscosity control up to 3000 to 15000 cps.

Examples of such water-soluble polymers are the same as the water-soluble polymers used in the aqueous phase component.

These water-soluble polymers are used in the range defined above. If the water-soluble polymer is used in the range defined above, the viscosity due to salts in the water drops, so that the particles become unstable and unstable. It becomes creamy.

As the lipophilic emulsifier in the present invention, at least one selected from sorbitan fatty acid ester, glycerin fatty acid ester, diglycerin fatty acid ester, methoxy polyetherene glycol, polyglycerol fatty acid ester, and polyoxyethylene fatty acid ester is used. do.

As the oil-soluble polymer in the present invention, at least one selected from silicon stearate, polybutene, aluminum stearate ethyl cellulose, polyethylene and polybutylene derivatives, ethyl cellulose and dimethicone is used.

The components as described above may be prepared in a multiphase emulsion type cosmetic according to the following manufacturing method.

First, 0.1 to 1.0 parts by weight of a water-soluble polymer as mentioned above and 0.1 to 5.0 parts by weight of salt as mentioned above and 0.1 to 5.0 parts by weight of protein are dissolved in 10.0 to 70.0 parts by weight of purified water to dissolve the aqueous phase component. Meanwhile, 0.5 to 10.0 parts by weight of the lipophilic emulsifier and 0.1 to 10.0 parts by weight of the oil-soluble polymer and 0.1 to 5.0 parts by weight of fatty acid ester metal salt were mixed and dissolved in 20.0 to 30.0 parts by weight of an oily agent to prepare an oily component. The aqueous phase component is dispersed in the oil phase component to obtain a W / O type emulsion.

Then, 10.0 to 30.0 parts by weight of the W / O type emulsion obtained above are mixed with 0.5 to 10.0 parts by weight of the lipophilic emulsifier and 10.0 to 20.0 parts by weight of an oily agent to prepare an oily component containing the W / 0 type emulsion. After dissolving 0.2 to 2.0 parts by weight of a water-soluble polymer as mentioned above in purified water of 10.0 to 60.0 center portion, preparing an external aqueous component, and then dispersing the oily component containing the W / 0 emulsion in the external aqueous component.
