Abstract
The ophthalmic composition of the invention comprises (A) lecithin and (B) at least one refrigerant selected from the group consisting of camphor, borneol, eucalyptus oil, and bergamot oil. In the ophthalmic composition, the odor of lecithin is efficiently masked by the refrigerant. The odor of lecithin after aging is also masked by the refrigerant. Since the refrigerant is volatile, the concentration thereof in a composition tends to gradually decrease. It is surprising that the odor of lecithin after aging can nevertheless be masked.
