Composition for contact lens solution containing peppermint and preparation method thereof

Abstract

The invention discloses a composition a contact lens solution containing peppermint, which is characterized in that the composition consists of the following components in percentage by weight: 0.001 to 0.3 percent of peppermint, 0.01 to 4 percent of isotonic regulator, 0.001 to 6 percent of lubricant-humectant, 0.001 to 5 percent of surfactant, 0.001 to 3 percent of chelating agent, 0.001 to 10 percent of buffering agent, 0.00001 to 2 percent of biocide, and 80 to 99.7 percent of pure water. A preparation method comprises the steps of: orderly placing the components into the pure water to dissolve, using sodium hydroxide and hydrochloric acid to adjust the pH value to be between 6.5 and 7.8, ensuring that the osmotic pressure is between 280 and 320 mo sm / kg.H2O, and performing aseptic filtration (0.22 mu m) on a solution. In the composition, the peppermint has special fragrance, sense of pungency and cool sense, stops pain and itching, and is effective to relieve the dryness and discomfort as well as the swelling of eyes. The contact lens solution is used for treating, disinfecting, cleaning, soaking, lubricating and storing contact lenses.

Description

technical field [0001] The present invention relates to a cleaning and lubricating composition. Specifically, the composition is a contact lens care solution including a peppermint composition and a preparation method thereof. Background technique [0002] Contact lenses can be divided into three types: rigid, semi-rigid and soft. Rigid contact lenses are made of polymethyl methacrylate (PMMA) which is basically impermeable to oxygen and siloxane and acrylate copolymers which are permeable to oxygen. semi-rigid contact lenses are made of silicone rubber that is permeable to oxygen and can maintain the normal respiration of the corneal surface, and a special wetting solution is required to keep it moist; in order to meet the comfort and physiological requirements; soft Contact lenses, most commonly lenses made from polyhydroxyethylmethacrylate (HEMA). HEMA molecules have a network structure, which enables the lens to absorb and release low-molecular liquids. The looser the ...

Problems solved by technology

Because contact lenses are worn into the eyes, they cover the front of the cornea, hindering the contact between the cornea and air and causing corneal hypoxia. In addition, tears not only moisten the cornea and conjunctiva, but also moisten the lens, resulting in lack of tears, causing lens wearers eye dryness, soreness

Therefore, the existing soft contact lenses cannot be worn continuously for a long time, and must be removed and sterilized every day
