Description

_? 31o66e-s i 2 lising, disinfecting and cleaning compositions containing compounds which emit active chlorine considerable and special measures were used commercially to reduce the problems.

A major commercial problem occurring during handling is due to the fact that these oxidizing chemicals can burn and emit toxic and unpleasant gases during combustion. IN in particular sodium, potassium and calcium dichloroisocyanurate salts and others chlorinated dry bleach compounds begin under the action of flame, spark or other high temperature sources to burn and continue to burn after the original heat source has been removed until the whole the amount of material consumed. This phenomenon is called self-entertaining and self-propagating decomposition. I _ W Certain organic additives intended for bleaching, sterilizing addition, disinfectant and detergent compositions are not easily compatible with chlorine-containing or chlorinated dry bleach compounds Examples of such additives are cationic surfactants, in particular quaternary ammonium compounds, which can react with and herein by initiating the combustion of certain chlorine-containing dry bleach compounds nings. p Another problem associated with the preparation of compositions containing chlorine-containing dry bleach compounds is the dust problem.

Fine particles, (dust) form part of chlorine-containing dry bleach compounds and these particles have a tendency to assume electrostatic charge. The charged dust particles tend to accumulate in corners and the nooks and crannies of the equipment used for the process handling of the chlorine-containing dry bleaches. Accumulation of fine particles zlar in and around bearings and other places where frictional heat develops are particularly unsuitable as frictional heat can initiate decomposition.

Precautions are taken to reduce such accumulation of dust in commercial operation.

Use of such bleach compounds commercially requires therefore special precautions, in particular if the associations dissolved (in bulk) and dispensed from a storage container for mixed with additives for compositions for bleaching, sterilizing, disinfection and cleaning. Such handling precautions of commercial quantities include: 1 '(l) Transport of chlorine-containing dry bleaches in individual holders instead of in. loose wagon loads or bulk wagon loads, (2) insulation of large quantities in separate buildings with special fire protection measures and fire-fighting equipment, (3) careful handling and 73106698 5 (M) warning markings on transport containers.

These precautions are intended to prevent accidental ignition. chlorine-containing dry bleach compounds with consequent evolution of chlorine and other toxic or harmful gases.

U.S. Patent No. 5,544,267 discloses use of hydrogenated calcium hypochlorite in solution to fill the essential commercial need for a non-combustible chlorine-containing inorganic dry bleaching agent. sub-association. Use of hydrated potassium hypochlorite (approx. monohydrate) is not, however, satisfactory. solution to the problem as this compound burns in mixed with certain organic substances, as shown by the less good substances of the substance properties when tested using the proposed method, designated "United States Bureau of Mines procedure RI-7594 "discussed below.

In addition, with hydrated calcium hypochlorite, calcium ion is introduced into which is less desirable as this increases the hardness of the water. level.

The invention thus relates to an improved method for preparation of bleach-Q sterilization, disinfection and cleaning compositions prepared by mixing a bleach compound which emits active chlorine in water and a compound belonging to the group gene builders, anionic, nonionic or cationic surfactants agents and detergent fillers. This improvement includes dispensing ring of the bleach compound from loose storage or bulk storage in mold of non-combustible dihydrate of sodium dichloroisocyanurate in a mixing zone in which mixture of the components takes place whereby fire risk and dust problems during preparation of the composition are significantly reduced by use of a non-combustible component with significantly reduced electrostatic tical charge.

The mixing of the components of a bleaching, sterilizing cleaning, disinfecting or cleaning composition can be achieved on many per se known methods and are typically carried out in a commercial mixing equipment which provides mechanical mixing of components components supplied to the device. The mixture and the addition of the components can be performed either continuously or intermittently.

Precautions to prevent dust accumulation are required not because the dihydrate particles have significantly reduced electrostatic charge Compared to other chlorine-containing dry bleaches.

The finishes. ' "Dispensing" in the present context refers to material removal from a first zone to a second zone and can be performed either as a continuous removal or a intermittent removal in any suitable quantity (unit of material fl. u 73 1 0666 -8 "Bulk storage zone" is a space within which a significant quantity of the content of a material is maintained essentially in a pure state. About 5 kg el- more clay is a significant quantity for bulk storage of chlorine-containing dry matter bleach because combustion of about 5 kg or more results in the release of unacceptably large amounts of harmful gases that require evacuation as well of large buildings.

"Mixing zone" is a space in which a mixture of materials takes place.- "Hazardous materials" means materials which, when tested according to it method known as the "United States Bureau of Mines prcposed procedure RI-7594 "has a flame propagation rate exceeding the velocity for pure sawdust used as a standard in this method. Such material accelerates instead of delays the combustion of sawdust.

"Non-combustible" refers to a property of a material, ie. of the material inability to separately maintain flames or combustion. Especially if an external flame is brought into contact with a non-combustible material, rial ooh then removed, the material does not continue to burn which is shown by the fact that the flame is self-extinguishing with unburned material Remaining.

"Detergent builders" are materials that can improve cleaning the detergent composition and cleaning effect of a detergent composition ( remedies). IN "Chlorinated dry bleach" is a bleach compound which releases active chlorine into water. Active chlorine is chlorine the type obtained by hydrolysis of chlorine-containing compositions or substances for the formation of hypochlorous acid (HOCI) and / or OCl'-Ion dependence on the pH of the system. Such end products of hydrolysis are combined set of oxygen with two negative charges in combination with a chlorine atom which must be positively charged. Such a positively charged chlorine atom is active chlorine is drawn. Active chlorine is obtained not only by hydrolysis of inorganic hypochlorite but is also obtained from N-chlorine compounds, for example chlorinated cyanuric acid, and other chlorine compounds containing N-Cl bond in which hydrolysis takes place with cleavage of the N-Cl bond and formation ning of Hoci ocn / eiier ocf-Jon.

When storing chlorine-containing dry bleaches such as one essentially pure material in bulk quantities exceeding approx. 5 kg causes incineration of such material risks and may cause serious disruption to a commercial operation, The danger is not only due to the combustion of the material developed heat or flames, but in addition there is a serious risk of due to the formation of chlorine gas and other toxic gases during rapid chemically induced decomposition of such materials. 7310666-8 There are many types of suitable bulk storage zones from which material can be drained. The choice of type in each particular case depends on suitability for the user, taking into account such factors as the type of use dispensing means, quantities to be dispensed and the type of transport container in which the chlorine-containing dry bleach is received.

An integrated system was often used using a single container designed to suit manufacturers, carriers and users of it chlorine-containing dry bleach. Examples of such containers in which it dry chlorine-containing bleach is transported and stored and from which the chlorine-containing dry bleach can be drained is "tote bins", barrels and similar. Discharge the chlorine-containing dry bleach directly from such a container means that the container acts as a bulk storage zone during the bottling period. Draining of material from such a holders can be provided with any suitable means, for example conveyor belts, screw conveyors and manual or automatic scoops fl system.

The best systems for draining materials from a bulk storage zone and mixing of the components of a composition comprises (1) storage of components 1 individual storage containers or "pockets" (bulk storage zone) that can be easily filled, (2) draining each component from the storage container with standard means, for example a conveyor belt, screw conveyor, gravity-based tapping means or other similar devices which also transfer the material from the storage zone to a mixing zone, usually a commercial mixing device, in which the materials are added in desired proportions and mixed to a homogeneous mixture. The mixture is then removed from the landing zone and packaged in any suitable units depending on the intended end-use ningen.

Typical additives for bleaching, sterilizing, disinfecting cleaning compositions used in combination with chlorine containing dry bleach compounds include detergent builders1, anionic, nonionic or cationic surfactants and detergent fillers average. The choice of additives used and the concentration of these in each particular composition depends on the intended use of the sitionen. Examples of compositions containing chlorine-containing dry bleaches means are compositions for automatic dishwashers for home use, commercial dishwasher compositions, scouring powders, household bleaches, commercial laundry bleaches, decontamination compositions. Typical cleaning agent compositions containing chlorine-containing dry bleaches and typical additives are as follows: (7310666-8 (2. 3.

Of the active chlorine sources, only sodium dichloroisocyanurate has -dihydrate has been shown to have fire-resistant properties that make the material falls within the proposed Class 1 according to the Bureau of Mines, which is the least risky class, while most others are chlorine-containing dry bleach compounds fall within the proposed class 3, which includes carries greater risk. 7310666-s 8 The combination of dihydrate with sodium dichloroisocyanurate contains less water than the dihydrate, for example monohydrate and / or anhydrous forms, resulting in a mixture with the advantageous properties described if a sufficient amount of dihydrate is present in the mixture so that the average amount is bound or combined water in the mixture exceeds ll%. Such mixtures with larger amount than 11% water is referred to in the present context as hydrated sodium dichloroisocyanurate. Because the dihydrate contains 14.1% bound water is hydrated sodium dichloroisocyanurate with an amount greater than 11% and up to 14.1% average bound H 2 O content suitable for use according to the invention. Additional amount of unbound water up to 2% may be present (except for 14, 1% bound water) without change ring of the properties of the dihydrate.

In addition to the non-combustibility, particles of sodium dichloroiso- cyanurate dihydrate significantly less electrostatically charged than aqueous free particles, which reduces the tendency of the fine particles to accumulates, eliminating one of the risks associated with the management of dry bleach compounds. * The following example shows the surprising difference in terms of fire the resistance between dihydrate of sodium dichloroisocyanurate and other chlorine containing dry bleach compounds. All proportions used are based on those on the weight unless otherwise stated.
