Provided is an ophthalmic composition comprising geranylgeranyl acetone and phosphate buffer, the reducing of the geranylgeranyl acetone content is very little even after long period storage. It is considered that the adhesion of geranylgeranyl acetone to the wall of ophthalmic container being inhibited. The adhesion of the ophthalmic composition comprising geranylgeranyl acetone and phosphate buffer to the wall of ophthalmic container is little. The adhesion of the ophthalmic composition comprising geranylgeranyl acetone and phosphate buffer to the contact lens is little. And the ophthalmic composition comprising geranylgeranyl acetone and phosphate buffer will not become turbidity even stored in low temperature.本發明係關於一種包含香葉基香葉基丙酮、及磷酸緩衝劑之眼科用組成物,其係在經長期保存後,香葉基香葉基丙酮的含有率降低極少者。咸認此係因抑制香葉基香葉基丙酮吸附至眼科用容器器壁之故。而且,包含香葉基香葉基丙酮、及磷酸緩衝劑之眼科用組成物,其吸附至隱形眼鏡的香葉基香葉基丙酮少。此外,包含香葉基香葉基丙酮、及磷酸緩衝劑之眼科用組成物即使以低溫保存,也不易變白濁。
