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.
Claims13
An ophthalmic composition comprising:
- (A) lecithin and
- (B) at least one refrigerant selected from the group consisting of camphor, borneol, eucalyptus oil, and bergamot oil.
A method for masking the odor of lecithin, comprising a step of mixing lecithin and at least one refrigerant selected from the group consisting of camphor, borneol, eucalyptus oil, and bergamot oil.
A method for inhibiting the increase of the odor of lecithin caused by aging, the method comprising a step of mixing lecithin and at least one refrigerant selected from the group consisting of camphor, borneol, eucalyptus oil, and bergamot oil.
A composition in which the odor of lecithin and the odor after aging are inhibited by at least one refrigerant selected from the group consisting of camphor, borneol, eucalyptus oil, and bergamot oil, and mixed with lecithin.
A method for reducing the cytotoxicity of borneol, comprising a step of mixing borneol and lecithin.
A method for inhibiting oxidation of lecithin, comprising a step of mixing lecithin and at least one refrigerant selected from the group consisting of camphor, borneol, eucalyptus oil, and bergamot oil.
