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.

When the amphiphilic anisotropic powder has a size of 1100 to 2500 nm, the weight ratio of the first monomer, the polymerization initiator and the crosslinking agent is 100 to 150: 0.5 to 2: 0 to 2, specifically, 115 to 125: 1: 0 Can be prepared from the first polymer spolide.

The asymmetric snowman-like amphiphilic anisotropic powder is preferably an amphoteric anisotropic powder whose weight ratio of the first monomer, the polymerization initiator and the crosslinking agent is 100 to 200: 0.1 to 1: 5 to 15, specifically 110 to 130: 1: 9 to 11 1 &lt; / RTI &gt; polymer spolide.

According to an exemplary embodiment, the second monomer and the polymerization initiator in (2) may be mixed in a weight ratio of 100 to 300: 1. 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). By mixing at a weight ratio within the above range, uniformity of the anisotropic powder can be enhanced.

According to one exemplary embodiment, the cross-linking agent may be a (meth) acrylate-based cross-linking agent and may be one or more of, for example, allyl methacrylate and ethylene glycol dimethacrylate , Specifically ethylene glycol dimethacrylate.

According to one exemplary embodiment, the second monomer content in step (2) may be 40 to 300 parts by weight when the first polymer spoil weight is 100 parts by weight. Specifically, if the second monomer content is in the range of 20 to 100 parts by weight based on 100 parts by weight of the first polymer spoil, the asymmetric snowman type powder is obtained, and when 100 to 150 parts by weight or 110 to 150 parts by weight, , 150 to 300 parts by weight, or 160 to 300 parts by weight, an asymmetric reverse snowman type powder is obtained.
