Definitions
- the present invention relates to a composition, a contact lens coating agent, a method for producing a contact lens, and a contact lens.
- Contact lens cleaning solution contact lens preserving solution, ophthalmic compositions such as eye drops (drugs), cleaning or cosmetic compositions for cleaning and caring for human skin, scalp, hair, etc., pharmaceuticals, or quasi-drugs
- ophthalmic compositions such as eye drops (drugs)
- cleaning or cosmetic compositions for cleaning and caring for human skin, scalp, hair, etc.
- pharmaceuticals or quasi-drugs
- the product is required to have low bactericidal action, but low irritation due to low cytotoxicity and high safety. For contact lens cleaning solutions, etc. There is also a need to suppress this.
- contact lenses are roughly classified into hydrous contact lenses (including soft contact lenses) and non-hydrous contact lenses (including hard contact lenses and soft contact lenses).
- Hydrous contact lenses are generally non-hydrous.
- the wearing feeling is better than the contact lens.
- conventional water-containing contact lenses have high water content, there are problems such as quick drying of the lenses and a decrease in oxygen permeability.
- a silicone hydrogel contact lens having a low oxygen content and a high oxygen permeability has been developed.
- this contact lens has become the mainstream.
- the silicone hydrogel has a problem that it easily adheres to lipid because the silicone chain contained therein is hydrophobic. If this lipid stain is left unattended and the contact lens is continuously used, it may cause clouding, a reduction in visual acuity correction power, and an adverse effect on the cornea. Therefore, removal of lipid stains adhering to the lens surface and suppression of lipid stains due to the hydrophilic treatment of the lens are important problems.
- bactericidal compounds are used in eye drops, contact lens cleaning solutions and preservatives.
- a bactericidal agent having a cationic group such as benzalkonium chloride is widely used because of its excellent bactericidal power.
- the contact lens is treated with a cleaning solution or a storage solution containing the bactericidal compound, or the bactericidal compound is added.
- the ophthalmic solution was used at the time of wearing a contact lens, the compound was sometimes adsorbed on the contact lens and accumulated sequentially in the contact lens. And due to this adsorption and accumulation, alteration and physical change of the contact lens may occur, and if the contact lens with accumulated bactericidal compound is worn for a long time, corneal staining etc. There was also the possibility of causing eye damage.
- benzalkonium chloride and the like have been conventionally used as a disinfectant and disinfectant in the medical and hygiene related fields, but there is a problem that irritation to the skin and ocular mucosa is high. In order to suppress irritation, if these blending amounts are decreased, the sterilization effect may not be sufficient, or if sufficient sterilization effect is obtained, the irritation becomes stronger and there is a problem in safety.
- a carboxy group or a sulfo group interacts with a cationic group of a bactericidal compound to suppress adsorption of the bactericidal compound to a lens that causes corneal staining. It is speculated that the effect of suppressing the adsorption of the bactericidal compound on the contact lens is not sufficient, and there is room for improvement in terms of safety.
- benzalkonium chloride or the like is applied to the skin, ocular mucous membrane or the like for sterilization or disinfection, there is room for improving safety without reducing the sterilization effect.
- composition that is less likely to reduce the bactericidal properties of a bactericidal compound and that is excellent in safety, lipid soil removal, and lipid adhesion suppression.
- a polymer having a repeating unit (A) having an HLB value of 14 or more and a repeating unit (B) having an HLB value of 1 or more and less than 14 hereinafter also referred to as “present polymer”.
- a composition containing a bactericidal compound having a cationic group hereinafter also referred to as “the present composition”.
- a contact lens coating agent hereinafter, also referred to as “the present coating agent” containing the present polymer, and a contact lens comprising a step of coating the polymer on at least a part of the surface of the contact lens.
- a contact lens having the polymer on at least a part of its surface hereinafter also referred to as “the present contact lens”.
- a composition having excellent safety such as excellent lipid removal and lipid adhesion suppression and low cytotoxicity.
- the cytotoxicity of the bactericidal compound is low, and is excellent in suppressing irritation, ophthalmic, cleaning, cosmetic, pharmaceutical, Or the composition for quasi drugs can be provided.
- Ophthalmic compositions having low storage properties and excellent storage stability in particular, contact lens cleaning solutions, contact lens storage solutions, contact lens mounting solutions, eyewashes and eye drops can be provided. For this reason, even if such an ophthalmic composition is used, eye damage such as corneal staining is unlikely to occur.
- the present coating agent and the present contact lens exhibit an excellent effect in the ability to suppress the adsorption of a bactericidal compound having a cationic group and the ability to suppress the adsorption of a lipid, and are excellent in the sustainability of the effect.
- composition and the coating agent contain the polymer, and the contact lens has the polymer on at least a part of its surface.
- the polymer will be described in detail.
- the present composition contains the present polymer together with a bactericidal compound
- the bactericidal compound is excellent in safety and removal of lipid stains and has excellent safety while maintaining the bactericidal action of the bactericidal compound.
- it can be suitably used as a bactericidal composition, particularly as an ophthalmic, cleansing, cosmetic, pharmaceutical, or quasi-drug composition.
- this composition is low in the cytotoxicity by the said bactericidal compound, and the adsorptivity to the contact lens of the said bactericidal compound.
- this composition is excellent in bactericidal properties required for eye drops and contact lens cleaning and storage solutions, but is less susceptible to degeneration and physical changes of contact lenses, and is also suitable for eye such as corneal staining. There is an effect that the occurrence of a failure hardly occurs.
- the present coating agent and contact lens also have the present polymer, they exhibit an excellent effect on the ability to suppress the adsorption of bactericidal compounds and the ability to suppress the adsorption of lipids, and are excellent in the sustainability of the effect. Therefore, it is possible to obtain a contact lens that is less likely to cause eye damage such as corneal staining.
- the lipid unit is removed by the action of the repeating unit (B) in the polymer with a contact lens or the like (for example, adsorbing to the contact lens).
- the surface of the contact lens and the like is hydrophilically modified by the repeating unit (A), it is considered that the adsorptivity to the contact lens and the like of the bactericidal compound and lipid soil is lowered.
- This polymer has a repeating unit (A) having an HLB value of 14 or more.
- the repeating unit (A) is not particularly limited as long as the HLB value is in the above range, but is preferably a hydrophilic repeating unit.
- the polymer may have one or more repeating units corresponding to the repeating unit (A).
- hydrophilic means that it has a strong affinity for water. Specifically, when 1 g or more of a homopolymer consisting of only one type of repeating unit (having a number average molecular weight of about 10,000 by the measurement method of the example) is dissolved in 100 g of pure water at room temperature (25 ° C.) The repeating unit is said to be hydrophilic.
- the HLB (Hydrophile-Lipophile Balance) value of the repeating unit (A) is 14 or more, preferably 17 or more.
- the HLB value is less than 14, the antibacterial compound and lipid adhesion suppressing effect may be insufficient, and the effect of imparting hydrophilicity to the contact lens surface may be insufficient.
- the HLB value in the repeating unit means a value calculated from the ratio of the organic value and the inorganic value of the compound (Oda equation), and “Formation Design With Organic Concept Diagram” [1998, NIHON EMULSION CO. , LTD].

該殺菌性化合物としては、カチオン性基を有すれば特に限定されず、公知の化合物を用いることができるが、例えば、塩酸ポリヘキサニド(ポリヘキサメチレンビグアナニド(PHMB))等のポリヘキサメチレンビグアニド誘導体、塩化ポリドロニウム等の塩化ポリドロニウム誘導体、ポリクオタニウム等のポリクオタニウム誘導体、クロルヘキシジン等のクロルヘキシジン誘導体、塩化ベンザルコニウム等の塩化ベンザルコニウム誘導体、塩化ベンゼトニウム等の塩化ベンゼトニウム誘導体が挙げられるが、殺菌作用を有しながらも、細胞毒性が低いなどの安全性が高い組成物が得られ、特に、コンタクトレンズ内部への浸透や蓄積が起こりにくく、充分な殺菌作用を有する組成物が得られる等の観点から、塩酸ポリヘキサニド、塩化ポリドロニウムが好ましい。
殺菌性化合物は、1種を単独で、又は2種以上を用いてもよい。

本組成物は、前述の通り殺菌性化合物による殺菌作用を維持したまま、脂質汚れの除去に優れ、安全性が極めて高い、具体的には、細胞毒性が低く殺菌性化合物による刺激性の抑制に優れることから、ヒトの皮膚、頭皮、毛髪等を洗浄、ケアするための洗浄用組成物、化粧用組成物等として使用することができる。

本コーティング剤は、本重合体を含むことを特徴とする。本コーティング剤によりコンタクトレンズ表面をコーティングすることで、カチオン性基を有する殺菌性化合物の殺菌作用の低下を抑制しながらも、該殺菌性化合物のコンタクトレンズへの吸着を抑制することができる。このため、本コーティング剤でコンタクトレンズ表面をコーティングすることで、カチオン性基を有する殺菌性化合物を含む組成物に触れた場合であっても、角膜ステイニング等の眼障害の発生が起こりにくいコンタクトレンズを得ることができる。また、本コーティング剤は、コンタクトレンズ、特に疎水性表面を有するコンタクトレンズ表面の親水化効果に優れ、脂質のコンタクトレンズへの吸着を抑制する効果にも優れる。さらに、本コーティング剤は、コンタクトレンズに対し高い吸着性を有し剥離しにくいため、前記親水化効果の持続性にも優れる。
本コーティング剤において、前記溶剤の含有量としては、50~99.9質量%が好ましく、80~99.9質量%がより好ましい。
本コンタクトレンズは、本重合体を表面の少なくとも一部に有することを特徴とする。また、本コンタクトレンズの製造方法は、本重合体を、コンタクトレンズ表面の少なくとも一部にコーティングする工程を含む。
本コンタクトレンズ及び前記製造方法で得られたコンタクトレンズは、その表面の少なくとも一部に本重合体を有するため、殺菌性化合物及び脂質のコンタクトレンズへの吸着が起こりにくい。
