PROBLEM TO BE SOLVED: To provide a lipophilic component-containing powder readily making the lipophilic component in stable and minute emulsified oil droplets by using a small amount of emulsifying agent based on an amount of the lipophilic component even when kept in a vehicle-containing state and effectively suppressing oozing-out of the oil when applying secondary processing such as compaction/molding to the lipophilic component and to provide a method for producing the powder.SOLUTION: The present invention provides lipophilic component-containing powder obtained by drying (A) a lipophilic component, (B) an amphipathic polymer containing the units represented by formulas (1) and (2) (wherein R1, R2, R3, R4, R5 and R6 are each H or a 1-5C alkyl group X is an anionic group Y is a hydrophobic group) in a specific ratio and (C) an O/W type emulsified material containing a vehicle and water and provides a method for producing the powder.COPYRIGHT: (C)2008,JPO&INPIT【課題】 賦形剤含有状態であっても、親油性成分に対して少量の乳化剤使用量で、親油性成分を容易に安定で且つ微小な乳化油滴とすることができ、更に親油性成分含有粉末を圧密/成型といった2次加工を施した場合に油の染み出しを効果的に抑制することができる親油性成分含有粉末及びその製造方法の提供。【解決手段】 (A)親油性成分、(B)構成単位(1)及び(2)を特定割合で含む両親媒性高分子化合物、(C)賦形剤及び水を含有するO/W型乳化物を乾燥させて得られる親油性成分含有粉末及びその製造方法。【化1】(式中、R1、R2、R3,R4、R5及びR6はH又はC1-5のアルキル基、Xはアニオン性基、Yは疎水性基を示す。)【選択図】 なし
