PROBLEM TO BE SOLVED: To provide resin particles which give not only spreadability and smoothness but also dry touch to cosmetics, also singly have smoothness and dry touch and show good dispersibility in a hydrophobic medium.SOLUTION: The crosslinked (meth)acrylate-based resin particles obtained by copolymerizing monomer components comprising a (meth)acrylate and a monomer having carboxy and whose surface is at least partially covered with a surfactant represented by general formula (1): R1-CO-NR2R3 (wherein, R1 is a 7-22C univalent hydrocarbon R2 and R3 are each H or a 2-3C hydroxyalkyl), a production method thereof, and the cosmetics containing the resin particles, are provided.COPYRIGHT: (C)2009,JPO&INPIT【課題】 伸び、なめらかさのみならず、さらさらした感触を化粧料に付与し、かつ粒子単独でなめらかさとさらさら感を有し、疎水性媒体において分散性が良好な樹脂粒子の提供。【解決手段】 (メタ)アクリル酸エステルと、カルボキシル基を有する単量体を含む単量体成分を共重合してなり、表面の少なくとも一部が一般式(1)で表される界面活性剤で被覆されてなる、架橋(メタ)アクリル酸エステル系樹脂粒子、その製造法並びにその樹脂粒子を含有する化粧料。【化1】〔式中、R1は炭素数7~22の1価炭化水素基、R2及びR3はH又は炭素数2~3のヒドロキシアルキル基を示す。〕【選択図】 なし
