A low-toxic SL-containing composition is provided. A low-toxic SL-containing composition having the following characteristics; (a) containing at least acid-type SL, fatty acid and hydroxy fatty acid derived from SL-producing yeast culture; acid-type SL, lactone-type SL, fatty acid and hydroxy When the total amount of fatty acids is 100% by mass, each ratio is the following in terms of dry weight: (1) Acid type SL: 94 to 99.99% by mass, (2) Lactone type SL: 0 to 2 Mass%, (3) total amount of fatty acid and hydroxy fatty acid: 0.01 to 4 mass%; (b) ratio of lactone type SL to 100 parts by mass of acid type SL contained in the composition containing low toxicity SL, or fatty acid and hydroxy fatty acid The ratio of (total amount) is 0 to 2.12 parts by mass or 0.01 to 4.25 parts by mass, respectively. (C) Which of acid type SL and lactone type SL contained in the low toxicity SL-containing composition It does not have an acetyl group. [Selection figure] None |
