PROBLEM TO BE SOLVED: To provide an organic acid-containing granule from which oozing out of oily ingredients is controlled and a method for producing the same.SOLUTION: The organic acid-containing granule having a volume-average primary particle size of &le50 &mum, includes 40-93 mass% of an organic acid, 0.1-30 mass% of oily ingredients, and 6-30 mass% of a water-soluble binder. The method for producing the same is described. Because of the fact that the volume-average primary particle size is not greater than 50 &mum, the organic acid-containing granule has a controlled oozing out of the oily ingredients in the granulation process and tabletting process, and an excellent shaping ability, even when the granule containing the oily ingredients is tabletted. The organic acid-containing granule is utilized as an intermediate for producing a bath agent.COPYRIGHT: (C)2011,JPO&INPIT【課題】油性成分の染み出しが抑制された有機酸含有造粒物と前記有機酸含有造粒物の製造方法の提供。【解決手段】体積平均一次粒子径が50μm以下である有機酸40~93質量%、油性成分0.1~30質量%、水溶性バインダー6~30質量%を含む有機酸含有造粒物とその製造方法。この有機酸含有造粒物は、有機酸の体積平均一次粒子径を50μm以下にすることにより、油性成分を含有する造粒物を打錠成形した場合であっても、顆粒化工程又は打錠化工程において油性成分が染み出しにくく、加工成型性に優れる。またこの有機酸含有造粒物は、浴用剤の製造中間体として利用することができる。【選択図】なし
