本発明は固体粒子を含有するコンタクトレンズ用洗浄組
成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to contact lens cleaning compositions containing solid particles.

がある。E. Prior Art 1 Since contact lenses are worn directly on the eyes, ocular secretions such as proteins and lipids may adhere to the lens surface and become smudged. Furthermore, if the lens is worn for a long period of time without removing this dirt, not only the wettability of the lens surface and the optical characteristics of the lens will be impaired, but also the eyeballs may be damaged. Therefore, contact lenses must be thoroughly cleaned before use.

易なため汚れ付着の問題は比較的少ないけれども、長年
使用していると落ちにくい汚れが蓄積することもある。Conventional hard contact lenses made of polymethyl methacrylate are chemically stable, so they can be used with a wide variety of cleaning agents, and they are easy to rinse, so there are relatively few problems with dirt adhesion. However, after years of use, dirt can accumulate that is difficult to remove.

レンズに比べて汚れやすく、割れ易いためにレンズの洗
浄が難しいという欠点を有する。In addition, in recent years, contact lenses made of polymethyl methacrylate have been found to cause complications due to insufficient oxygen supply to the cornea of the eye, and lenses with high oxygen permeability containing organic silane compounds and fluorine compounds have been developed to improve the situation. is planned. However, -M has the disadvantage that when worn for a long period of time, it is more likely to get dirty and break than conventional hard contact lenses made of polymethyl methacrylate, making it difficult to clean the lenses.

Depending on the lens material, these cleaning agents alone may not have a sufficient cleaning effect.

タクトレンズ用洗浄組成物が提案されている。In addition, proteolytic oxygen has the disadvantage that it has a low removal effect on stains other than proteins, and that it takes time to perform the work. Therefore, inorganic abrasives such as those disclosed in JP-A-63-146017 and JP-A-63-146017,
The surfactant solution contains an organic abrasive as disclosed in Japanese Patent Publication No. 159821 or a mixed inorganic and organic abrasive as disclosed in Japanese Unexamined Patent Publication No. 1-172815. Contact lens cleaning compositions for physically removing dirt have been proposed.

かった。[Problems to be Solved by the Invention] The abrasives contained in conventional contact lens cleaning agents are either inorganic or organic, or a mixture thereof. Although inorganic abrasives are hard and have abrasive power and are good at removing dirt, they have the risk of damaging and deforming lenses. On the other hand, organic abrasives are soft and do not scratch the lens and have good shape retention, but have weak cleaning power. In the case of mixtures with
It was not something that compensated for the shortcomings of both and utilized them as strengths.

ろにある。Therefore, the present invention aims to solve the complaints by making the disadvantages of both organic and inorganic abrasives into advantage.The purpose of the present invention is to use organic abrasives with appropriate particle size and inorganic abrasives. The objective is to provide a cleaning agent that does not cause lens deformation and has a high cleaning effect by mixing the cleaning agent and the cleaning agent at a predetermined weight ratio.

This weight ratio is more preferably 85 to 95 parts of organic solid particles and 15 to 5 parts of inorganic solid particles.6 The weight ratio of organic solid particles is 80 parts or less (
If the weight ratio of inorganic solid particles is 20 parts or more, the risk of damaging the lens increases, and if the weight ratio of organic solid particles is 99 parts or more (weight ratio of inorganic solid particles 1 part or less) If this happens, dirt removal is insufficient.

みることができた。[Function] There are many contact lens cleaning compositions that contain solid particles, but due to the difference in the physical cleaning effect of the solid particles, there have been problems with cleaning power, scratches, and lens shape retention. 6 In the present invention, these problems can be alleviated by mixing inorganic solid particles and organic solid particles having a predetermined particle size at a predetermined weight ratio. Furthermore, the cleaning effect was improved by limiting the mixing ratio of organic solid particles and inorganic solid particles. Furthermore, by limiting the particle size of the fixed particles, it was possible to improve the lens' shape retention and scratch resistance.
