Liquid composition for oral use and method for improving resilience to freezing thereof

Provided is a liquid composition for oral use with outstanding stability of external appearance when frozen and thawed (resilience to freezing), and which imparts an agreeable sensation when used, containing an emulsion (A) in which the oil component is a liquid at 25 DEG C, and N-acyl taurate (B), wherein the content of N-acyl taurate (B) is 0.2-0.8 mass%. Also provided is a method for improving the resilience to freezing of the liquid composition for oral use by including 0.2-0.8 mass % of N-acyl taurate (B) in a liquid composition for oral use containing the emulsion (A) in which the oil component is a liquid at 25 DEG C. 本发明提供种液体口腔用组合物和改善所述液体口腔用组合物冷冻复原性的方法。所述液体口腔用组合物冷冻融化时的外观稳定性(冷冻复原性)优异，还可以赋予良好的使用感，其含有乳浊液(A)和N-酰基牛磺酸盐(B)，其中，乳浊液(A)的油性成分含有在25℃下为液体的油脂，N-酰基牛磺酸盐(B)的含量为0.2～0.8质量％。改善所述液体口腔用组合物冷冻复原性的方法在混合有乳浊液(A)的液体口腔用组合物中混合N-酰基牛磺酸盐(B)0.2～0.8质量％，其中，乳浊液(A)的油性成分含有在25℃下为液体的油脂。
