Definitions
- TITLE Composition for the treatment of objects intended to be disinfected
- the invention relates to a composition for the treatment of objects intended to be disinfected such as, for example, medical, surgical and / or endoscopic instruments, and / or installations in the food industry.
- the invention may also be used in all fields, in particular household and / or professional, for which the disinfection of utensils, surfaces and / or others, is desired.
- the use of objects in hospitals and / or food industries requires prior treatment to eliminate all microbial contamination and contamination such as blood, proteins or others.
- the quality of the first step i.e. the detergency step, is paramount.
- the resistance of bacteria to antimicrobial agents when included in a biofilm is much higher than that presented by bacteria in suspension. This is why the cleaning phase must necessarily allow the disorganization of microorganisms structured in biofilm so that the effectiveness of disinfectant molecules on micro- thus suspended organisms be increased.
- a first object of the invention is to propose a composition for the treatment of objects such as, for example, medical, surgical and / or endoscopic instruments, and / or installations in the food industry, which overcomes the aforementioned drawbacks and makes it possible to destructure the biofilm capable of developing from microorganisms contaminating their surface.
- the invention thus relates, according to a first aspect, to a composition for the treatment of objects intended to be disinfected such as, for example, medical, surgical and / or endoscopic instruments, and / or installations in the food industry, comprising enzymatic agents, characterized in that all or part of said agents are capable of targeting at least part of the binders of the biofilm capable of developing from microorganisms contaminating an inert surface.
- enzymatic agents characterized in that all or part of said agents are capable of targeting at least part of the binders of the biofilm capable of developing from microorganisms contaminating an inert surface.
- this entails the risk, in particular, of sucking a certain, non-solubilized quantity of this powder in micro-circuits, for example endoscopic channels, and of obstructing them at least partially.
- the same risk can arise from the encapsulation residues of the enzymes themselves.
- a second object of the invention is to propose a composition for the treatment of objects such as, for example, medical, surgical, and / or endoscopic instruments and / or installations in the food industry, which overcomes these drawbacks and is stabilized in liquid form, this even in the presence of said antimicrobial agents in said composition.
- the invention thus relates, according to another aspect, to a composition for the treatment of objects intended to be disinfected such as, for example, medical, surgical and / or endoscopic instruments and / or installations in the food industry, comprising enzymatic agents and the formulation of which is adapted in order to ensure their stability, in particular thanks to the choice of solvents used and / or in the use of chelating agents of the sodium iminodisuccinate and / or ethylene diamine sodium disuccinate type.
- the invention relates to a composition for the treatment of objects intended to be disinfected such as, for example, medical, surgical and / or endoscopic instruments and / or installations in the food industry. It includes enzymatic agents.
- all or part of said enzymatic agents are chosen for their specific activity with respect to vis of substrates, in particular of the exopolysaccharide type, identified as being binders of the biofilm capable of developing from microorganisms contaminating an inert surface, that is to say substrates allowing the adhesion of microorganisms to surfaces.
- composition according to the invention thus allows the destructuring of the biofilm. Thanks to this action of disorganization of the microbial colonies which have adhered to the surfaces, all of the microorganisms are suspended in the medium and are thus more easily destroyed. The objects to be treated can then be more effectively disinfected.
- Said enzymatic agents consist, for example, of a mixture of dextranase, alginate lyase, glucosidase, carbohydrase, and / or cellulase.
- composition according to the invention may also contain possibly other enzymes capable of intervening in a process for removing organic stains such as, in particular, proteases, lipases and / or amylases.
- the quantities of enzymes used form, for example, by weight, 0.1% to 25% of the composition.
- said composition in liquid form.
- said composition consists, for example, of a mainly non-aqueous medium. Its water content is, for example, less than
- the composition according to the invention will comprise antimicrobial agents such as, for example, quaternary ammonium salts and / or derivatives of biguanide and / or alkylaminoalkylamines and / or derivatives of phosphonium and / or d 'Oxidizing agents liberating oxygen.
- antimicrobial agents such as, for example, quaternary ammonium salts and / or derivatives of biguanide and / or alkylaminoalkylamines and / or derivatives of phosphonium and / or d 'Oxidizing agents liberating oxygen.
- antimicrobial agents such as, for example, quaternary ammonium salts and / or derivatives of biguanide and / or alkylaminoalkylamines and / or derivatives of phosphonium and / or d 'Oxidizing agents liberating oxygen.
- They form, for example, by weight, between 0.1 and 25% of the composition.
- Such an association could also be favored by the use of chelating agents, of the sodium iminodisuccianate and / or ethylene diamine sodium disuccinate type, having the triple characteristic of being non-denaturing and / or inactivating with respect to enzymes. , to synergize the activity of antimicrobial principles and to be biodegradable.
- said composition may also include agents capable of strengthening its detergent action. They are, for example, ethoxylated fatty alcohols and / or ethoxylated alkylphenols and / or copolymers of ethylene oxide and / or propylene and / or alkylpolyglycosides.
- composition in accordance with the invention may also comprise anti-corrosion agents, active or passive, and / or mild alkaline reserves, such as monoethanolamine or triethanolamine.
- Said composition is, for example, miscible in any proportion with water.
- the dose for use varies, in particular, by weight, from 0.1 to 5% by volume of water.
- its pH is fixed, substantially, between 4 and 11 at the use dilution.
- Said composition can be used in the form of a bath in which the objects intended to be disinfected are immersed to be treated manually or using a machine. It may also be a spray or other.
