Description

TECHNICAL FIELD The present invention relates to an emulsion cosmetic composition comprising fine wax particles,

The present invention relates to an emulsified cosmetic composition comprising fine wax particles and a process for producing the same.

In the conventional emulsification system using a surfactant, when the underwater type emulsion is manufactured using the high melting point wax, the surfactant exhibits fluid characteristics at the emulsified interface, so that the emulsion particles are coalesced or the inward precipitation occurs due to the crystallization of the wax It is difficult to maintain the stability of the formulation.

Therefore, in the production of emulsified cosmetics in which micrometer-sized fine wax particles are dispersed, emulsification conditions must be precisely controlled in order to form solid fine wax particles by directly injecting wax in a molten state during the emulsification process. In the preparation of such a surfactant system, wax particles may be aggregated with each other even after preparation through elaborate emulsification conditions, resulting in particle aggregation and excessive viscosity increase.

Accordingly, there has been proposed a method of preparing a cosmetic composition for emulsification by separately preparing fine wax particles, and emulsifying the composition into a formulation and dispersing it in a formulation. In this case, a separate process is required, which is not economical in terms of the process. Further, in order to disperse the fine wax particles thus prepared, a separate additive must be included and the emulsion stability is low.

The size and shape of the spherical fine particles made of the polymer are controlled according to the manufacturing method, and thus the application possibility is expanded. One of its applications is Pickering emulsion which can form stabilized macroporous particles using micro spherical particles. O / W emulsified particles are formed at a contact angle of 90 ° or more, and W / O emulsion particles are formed at a temperature of 90 ° or less depending on the degree of hydrophilicity / hydrophobicity of the spherical particles.

Attempts have been made to produce new anisotropic powders by imparting amphiphilic properties, both hydrophilic and hydrophobic, to the microspheres. An example is the Janus spherical particles. However, due to the morphological limitations of these spheres, there is a limit to the chemical anisotropy. In other words, although it is morphologically anisotropic, it is totally hydrophobic or hydrophilic, so that there is a limit to chemical anisotropy.

It has been attempted to produce anisotropic powders having surface activity by imparting chemical anisotropy together with geometric shape control. However, despite the advantage of its applicability of amphiphilic anisotropic powder, up to now, Has not been specifically developed, and there is a problem that it is difficult to mass-produce uniformly in the industry, so that no practical industrial application has been made.

The hydrophobic portion and the hydrophilic portion of the amphipathic anisotropic powder have different orientations toward the interface, thereby forming a large emulsion particle, and it is possible to realize a formulation with excellent feeling of use. It has been difficult to form stable emulsified particles having a particle diameter of several tens of micrometers as the conventional molecular level surfactant and the interface film thickness of the surfactant is about several nanometers. On the other hand, in the case of the amphiphilic anisotropic powder disclosed in the present specification, Is increased to about several hundreds of nm and the stabilized interfacial film is formed due to strong bonding between the particles, the emulsification stability can be greatly improved.

The method for producing a cosmetic composition according to an embodiment of the present invention may include preparing the amphiphilic anisotropic powder and emulsifying the oil phase and the water phase using the amphoteric anisotropic powder produced.

In one embodiment of the present invention, the amphiphilic anisotropic powder is prepared by (1) stirring a first monomer and a polymerization initiator to prepare a first polymer spoloid; And (2) stirring the prepared first polymer spoloid with a second monomer and a polymerization initiator to prepare an anisotropic powder having a second polymer spoloid formed thereon.

In one example, the method may further include (3) introducing a hydrophilic functional group into the anisotropic powder prepared above after the anisotropic powder of (2) is produced.

In the above steps (1), (2) and (3), stirring may be rotary stirring. It is preferable to rotate and stir because chemical mechanical modification and homogeneous mechanical mixing are required for producing uniform particles. The rotational stirring may be performed in a cylindrical rotating reactor, but the rotational stirring method is not limited thereto.

At this time, the design inside the reactor has a great influence on powder formation. The size and location of the baffles in the cylindrical rotating reactor and the degree of spacing between the impeller and the baffles greatly influence the uniformity of the particles produced. It is desirable to minimize the interval between the blades of the inner wing and the impeller to equalize the convection flow and the strength thereof, and to feed the powder reaction liquid below the wing length and to maintain the impeller rotation speed at a high speed. 200 rpm, and the length to diameter ratio of the reactor may be 1 to 3: 1 to 5, more specifically 10 to 30 cm in diameter and 10 to 50 cm in height. The reactor size can be varied in proportion to the reaction capacity. The material of the cylindrical rotating reactor may be ceramics, glass, etc., and the temperature at the time of stirring is preferably 50 to 90 ° C.

In the cylindrical rotating reactor, the simple rotation method is capable of producing uniform particles, and is a low energy method requiring less energy and maximizing the reaction efficiency, enabling mass production. The conventional tumbling method in which the reactor itself rotates requires high energy and restricts the size of the reactor since the entire reactor must be tilted at a constant angle and rotated at high speed. The amount produced due to reactor size limitations was also limited to small quantities of the order of several hundreds of milligrams to several grams, making them unsuitable for mass production.

According to one exemplary embodiment, the first monomer and the second monomer may be the same or different, and specifically may be (meth) acrylate-based monomers.

The ionic polymer increases the viscosity of the trauma by the expansion of the macromolecular chain and reduces the fluidity of the powder. This makes it possible to prevent the particles produced by the polymer polymerization from becoming entangled and united (bonded) to each other and to maintain a uniform size.

When the amphiphilic anisotropic powder has a size of 300 to 400 nm, the weight ratio of the first monomer, the polymerization initiator and the crosslinking agent is 110 to 130: 1: 1 to 5, specifically 115 to 125: 1: 2 to 4 Can be prepared from the first polymer spolide.

In another aspect, the second monomer and the polymerization initiator may be present in an amount of from 160 to 250: 1, or from 170 to 250: 1, or from 180 to 250: 1, or from 190 to 250: 1, or from 200 to 250: : 1, or 220 to 250: 1, or 230 to 250: 1, or 240 to 250: 1.

In another aspect, the second monomer, the polymerization initiator and the cross-linking agent may be mixed in a weight ratio of 100 to 300: 1: 0.001 to 10 by further adding a cross-linking agent in the step (2).
