PROBLEM TO BE SOLVED: To provide low-toxicity SL-containing compositions.SOLUTION: A low-toxicity SL-containing composition has the following characteristics: (a) it contains at least an acidic SL derived from an SL-producing yeast culture, and a fatty acid and a hydroxy fatty acid, where their respective contents are as follows in terms of dry weight when the total amount of the acidic SL, lactonic SL and fatty acid and hydroxy fatty acid is 100 mass%: (1) 94-99.99 mass% of the acidic SL, (2) 0-2 mass% of the lactonic SL, and (3) 0.01-4 mass% of the fatty acid and hydroxy fatty acid in total (b) the ratio of the lactonic SL, and the ratio of the fatty acid and hydroxy fatty acid (in total), to 100 pts.mass of the acidic SL contained in the low-toxicity SL-containing composition are respectively 0-2.12 pts.mass and 0.01-4.25 pts.mass and (c) neither the acidic SL nor lactonic SL contained in the low-toxicity SL-containing composition has an acetyl group.SELECTED DRAWING: NoneCOPYRIGHT: (C)2016,JPO&INPIT【課題】低毒性SL含有組成物を提供する。【解決手段】下記特徴の低毒性SL含有組成物;(a)SL産生酵母培養物に由来する酸型SL、脂肪酸及びヒドロキシ脂肪酸を少なくとも含有し、酸型SL、ラクトン型SL、並びに脂肪酸及びヒドロキシ脂肪酸の総量を100質量%とした場合に、それぞれの割合が乾燥重量に換算して下記である(1)酸型SL:94~99.99質量%、(2)ラクトン型SL:0~2質量%、(3)脂肪酸及びヒドロキシ脂肪酸の総量:0.01~4質量%;(b)低毒性SL含有組成物に含まれる酸型SL100質量部に対するラクトン型SLの割合、または脂肪酸及びヒドロキシ脂肪酸(総量)の割合が、それぞれ0~2.12質量部または0.01~4.25質量部、(c)低毒性SL含有組成物に含まれる酸型SL及びラクトン型SLがいずれもアセチル基を有しない。【選択図】なし
