摘要:
A skin cosmetic composition comprising: a hydrogel particle comprising a non-crosslinked hydrogel containing an oil component therein dispersed in an aqueous medium; a hydrogel particle comprising a non-crosslinked hydrogel containing an oil component therein; and a process for preparing a hydrogel particle comprising the steps of discharging an oil component-emulsified or dispersed solution prepared by dissolving a non-crosslinked hydrogel in an aqueous solution, with vibration from an orifice to form droplets; and cooling the droplets to solidify.
摘要:
A process for preparing a solid particles-containing emulsion comprising mixing an oil droplets-in-water emulsion with lipophilic solid particles or a dispersion thereof, thereby allowing to include the lipophilic solid particles in the oil droplets. The solid particles-containing emulsion can be suitably used in paints, inks for ink jet printers, fiber-treated agents, coating materials, adhesives, skin cosmetics, hair cosmetics, and the like.
摘要:
A hydrogel particle producing method includes spraying into an atmosphere a dispersion containing an oil component dispersed in an aqueous component solution which contains a gel source of non-crosslinked hydrogel dissolved therein such that formed droplets are cooled to solidify, a gelation temperature of the gel source of non-crosslinked hydrogel being equal to or higher than 30° deg. C.
摘要:
A hydrogel particle contains a continuous phase portion of non-crosslinked hydrogel and a large number of disperse phase portions dispersed in the continuous phase portion. Each of the large number of disperse phase portions is a solid phase containing an oil component and particles of zinc oxide dispersed therein.

摘要:
The present invention relates to a method of suppressing coloration of catechins, which contains adding, to catechins, a water-soluble polymer forming a water-insoluble complex with catechins, as well as hydrogel particles containing a water-insoluble complex between catechins and a polymer forming a water-insoluble complex with catechins. Further, the present invention relates to a dentifrice composition containing hydrogel particles containing catechins and a polymer forming a water-insoluble complex with catechins, a binder and water.
