Cosmetic composition comprising acrylic copolymer composition and manufacturing method thereof

The specification discloses a cosmetic composition comprising a (meth)acrylic copolymer composition and a method for preparing the same.

The surfactant forms a curved surface in the oil or water phase direction according to the geometrical shape (packing parameter), and one part of the surfactant is hydrated with the aqueous phase and the other part is solvated with the oil to form a water-in-oil type (w/o). or an oil-in-water (o/w) emulsion.

On the other hand, unlike conventional molecular surfactants, Pickering emulsions using spherical solid powder are w/o or o/w depending on the degree of wettability at the interface of the solid powder surface, that is, depending on the degree of lipophilicity or hydrophilicity. to form an emulsion. There is a contact angle as a factor that determines the directionality of the face film. If the contact angle is less than 90 degrees, a large part of the particle surface exists as an aqueous phase to generate o/w. create

In general, the Pickering emulsion can produce large emulsified particles compared to the existing surfactant system, and the generated emulsified particles prevent coalescence due to physical stabilization to form stabilized emulsified particles. Therefore, a study on a method of changing the physical properties of the emulsified particles according to the particle size and properties of the Pickering solid particles and their physical properties has been conducted. However, Pickering solid particles possess a hydrophilic or lipophilic surface, but do not possess amphotericity like surfactants.

Accordingly, attempts have been made to increase the surface active force by imparting an amphiphilic surface active force to the spherical powder particles used for Pickering, and for example, Janus spherical particles can be cited. However, due to geometric limitations and difficulties in uniform mass production, practical application has not been made.

Since the hydrophobic part and the hydrophilic part of the amphiphilic anisotropic powder have different orientations to the interface, it is possible to form large emulsified particles and to implement a formulation with excellent feel.

Since uniform mechanical mixing is required in addition to chemical modification in order to produce uniform particles, rotational stirring is preferable. The rotational stirring may be performed in a cylindrical rotational reactor, but the rotational stirring method is not limited thereto.

At this time, the design inside the reactor has a great influence on the powder formation. The size and location of the baffles in the cylindrical rotary reactor and the degree of spacing with the impeller greatly affect the uniformity of the particles produced. It is desirable to minimize the blade gap between the inner blade and the impeller to equalize the convective flow and its strength, and the powder reaction liquid is introduced below the blade length and the impeller rotation speed is preferably maintained at a high speed. It may be rotated at a high speed of 200 rpm or more, and the length ratio of the diameter and height 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.

In a cylindrical rotary reactor, the simple rotation method enables the production of uniform particles, is a low-energy method that requires little energy, and has the characteristics of enabling mass production by maximizing reaction efficiency. The conventionally used tumbling method in which the reactor itself rotates requires high energy to rotate the entire reactor at a high speed by tilting it at a certain angle, and the size of the reactor is limited. Due to the limitation of the size of the reactor, the amount produced was also limited to a small amount of about several hundred mg to several g, making it unsuitable for mass production.
