PURPOSE:To provide the titled liquid agent such as eye drop, etc., containing polyoxyethylene hardened castor oil, glycyrrhizic acid salt and quaternary ammonium-type cationic surfactant as well as tocopherols and free from clouding nor precipitation even in contact with polyethylene. CONSTITUTION:The titled liquid agent such as eye drop, etc., contains (A) 0.005-0.05wt% tocopherols, (B) 0.1-0.3% polyoxyethylene hardened castor oil, (C) 0.05-0.15% glycyrrhizic acid salt and (D) quaternary ammonium-type cationic surfactant. The liquid agent can be used in contact with polyethylene without causing clouding and precipitation and keeping the transparency over a long period and, furthermore, the loss of tocopherol content can be prevented. The component D is preferably benzetonium chloride, cetylpyridinium chloride, etc., and the molar ratio of C:D is adjusted to (0.5-5):1.
