The invention discloses eye wash with moisturizing, antibacterial and
antioxidant effects and a preparation method of the eye wash, and the eye wash comprises the following components in percentage by
mass: 0.1-5% of a
dendrobium nobile extract; 0.1%-2% of a Japan
cypress leaf extract; 0.001 to 0.005 percent of a freshener; 0.1 to 3.0% of a
humectant; 0.5 to 5.0 percent of a pH value
regulator; 0.4-6.0% of an
osmotic pressure regulator; and the balance of
purified water. The preparation method comprises the following steps: weighing the
dendrobium nobile extract, the chamaecyparis obtusa leaf extract, the freshener and the
humectant according to the formula ratio, adding part of
purified water, and uniformly stirring and mixing; the pH is adjusted to 6.8-7.8, the
osmotic pressure is 260-340 mOsm / kg H2O, finally, the balance of
purified water is added, the materials are stirred and mixed to be uniform, then
filtration sterilization is conducted, filtrate is taken and subpackaged, and the eye washing liquid is obtained. Polyphenols in the
dendrobium nobile extract and
hinokitiol in the chamaecyparis obtusa leaf extract have a synergistic effect in
antioxidant and antibacterial aspects,
hinokitiol has an
antibacterial effect on various
bacteria,
polyphenol also has
antioxidant and antibacterial characteristics, and the
antibacterial effect and the antioxidant effect can be enhanced by combining the
polyphenol and the
hinokitiol.
