Problems solved by technology

[0004] In addition, Patent Document 2 pointed out that for silicone polymers commonly used in cosmetics, it is desired to impart water repellency, improve adhesion with skin, etc., and compatibility with coexisting oil agents, but in order to improve Compatibility, if a long-chain alkyl group (hydrophobic group) is introduced into the silicone polymer, the hydrophilicity will disappear, and in order to improve the adhesion, if a hydrophilic group is introduced, the hydrophobicity will disappear, and it is difficult to solve the phase problem at the same time Capacitance and tightness

Embodiment 1

[0044] (Example of producing a non-polymerizable silicone acrylic copolymer in a polymerizable monomer liquid)

[0045] First, lauryl methacrylate was added to a solution in which 4 parts of V-65 was dissolved in 200 parts of polyethylene glycol dimethacrylate (manufactured by Shin-Nakamura Chemical Industry Co., Ltd., trade name: NK1G) prepared in advance. (manufactured by Kao Corporation, trade name: LMA) 200 parts and non-polymerizable silicone acrylic copolymer (manufactured by Shin-Etsu Chemical Industry Co., Ltd., trade name: KP-578, active ingredient 100%) 20 parts, they are uniformly stirred Mix to prepare a polymerizable monomer liquid. KP-578 used above is a graft polymer formed of acrylic polymer and dimethylpolysiloxane.

[0046] Next, in another container, 80 parts of PVA as a dispersion stabilizer was dissolved in 1600 parts of ion-exchanged water, and the polymerizable monomer liquid prepared above was added and mixed, and stirred at 2500 rpm for 5 minutes wit...

Embodiment 2

[0048] (an example of producing a non-polymerizable polyether alkyl co-modified silicone in a polymerizable monomer liquid)

[0049]First, 200 parts of modified bisphenol diacrylate (manufactured by DAICEL-ALLNEX LTD., trade name: EBECRYL150), non- Polymerizable polyether alkyl co-modified silicone (manufactured by Shin-Etsu Chemical Co., Ltd., trade name: KSG-310, active ingredient 25 to 35%) 80 parts and previously prepared propylene glycol monomethyl ether acetate 20 parts A solution of 4 parts of V-65 was dissolved in one part. However, they were uniformly stirred and mixed to prepare a polymerizable monomer liquid. Next, in another container, the water phase in which 88 parts of PVA as a dispersion stabilizer was dissolved in 1600 parts of ion-exchanged water was used, except that, in the same manner as in Example 1, operations such as subsequent cleaning were performed, Resin beads containing non-polymerizable silicone immobilized were obtained. KSG-310 used above is...

Embodiment 3

[0050] (Example of production by including non-polymerizable trimethylsiloxysilicate in polymerizable monomer liquid)

[0051] Lauryl methacrylate (Kao Co., Ltd., trade name: LMA) 280 parts and non-polymerizable trimethylsiloxysilicate (Shin-Etsu Chemical Co., Ltd., trade name: X-21-5250, active ingredient 50%) 40 parts, These were uniformly stirred and mixed to prepare a polymerizable monomer liquid, and in the same manner as in Example 1, resin beads immobilized and containing non-polymerizable silicone were obtained. The X-21-5250 used above is a mixture of 50% of trimethylsiloxysilicate and 50% of cyclopentasiloxane which is a cyclic silicone oil.

Abstract

Provided are: resin beads, said beads per se containing silicone in a fixed state and, therefore, being capable of exhibiting a water and oil-repellent effect when used in cosmetics, etc. so as to enable the provision of cosmetics showing little makeup deterioration; and a method for manufacturing the resin beads. Resin beads characterized by being resin particles (a copolymer) that are prepared by suspension-polymerizing a monomer mixture, said monomer mixture containing a plurality of monomers having copolymerizable functional group, at least under conditions where non-polymerizable silicone is present, and thus contain the silicone in a fixed state; and a method for manufacturing the resin beads.

Description

technical field [0001] The present invention relates to resin beads which are resin particles containing non-polymerizable silicone, their production method, and their use. More specifically, the present invention relates to a resin bead containing immobilized non-polymerizable silicone as a functional material capable of imparting water repellency and oil repellency, a method for producing the resin bead, and a method requiring such a function. Products in the field of sexuality, such as cosmetics, coating drugs, skin external drugs such as patches, paints, molded bodies, films, coating agents, dispersions, printing inks, inkjet inks, or resin compositions. Background technique [0002] Resin beads have been used in various fields such as matting agents, lubricants, and anti-blocking agents due to their spherical characteristics. Furthermore, in cosmetics, various resin powders (resin particles) are used for color cosmetics in order to improve ductility. However, these re...
