Abstract
The present invention relates to a non-aqueous dispersion, a preparation method therefor, and a cosmetic composition comprising same. The present invention can provide: a dispersion applicable to a coating agent and a cosmetic composition, which are well cleansed by even a large amount of water or a typical cleanser without an specific make-up remover or oil cleanser while having an excellent makeup lasting effect; a preparation method therefor, and a cosmetic composition comprising same.
Claims7
A method for preparing a non-aqueous dispersion, comprising the steps of:
- S1) a first step of mixing and polymerizing at least one hydrophilic monomer selected from vinyl pyrrolidone and 2-hydroxyethyl acrylate with at least one hydrophobic monomer selected from n-butyl acrylate, and stearyl methacrylate to obtain a copolymer in a non-aqueous solvent;
- and
- S2) a second step of adding and polymerizing at least one hydrophilic monomer selected from acryl and vinyl compounds in the presence of the copolymer in the non-aqueous solvent from the first step to form the non-aqueous dispersion,
- wherein the copolymer obtained from the first step is used as a dispersion stabilizer for the hydrophilic monomer of the second step, and
- wherein a content of the hydrophilic monomer mixed in step S1) is 1-40 wt % based on a total weight of the monomers mixed in step S1), and a content of the hydrophobic monomer mixed in step S1) is 60-99 wt % based on the total weight of the monomers mixed in step S1),
- and
- wherein the non-aqueous solvent comprises C10-C16 hydrocarbon-containing oil.
