Definitions
- the object of the present invention relates to preparing and obtaining a solid detergent preferably, though not exclusively, used in industrial contexts, such as in industrial dishwashers.
- caustic soda In liquid detergents of this type caustic soda cannot be present in concentrations greater than 10-20% by weight, in order to avoid phase separations in the detergent. As a result the cleaning power of such detergents is limited.
- the object of the present invention is to provide a detergent for industrial use, in particular a detergent for dishwasher machines that overcomes the drawbacks stated above.
- a further object of the present invention is a method of preparing said detergent.
- the industrial use detergent according to the invention is a solid mass or agglomerate comprising an alkali metal or alkaline earth metal hydroxide and a medium , characterised by the fact that said medium is glycerol and/or a homologue or isomer.
- the alkali metal or alkaline earth metal hydroxide will preferably be selected from sodium, potassium or calcium hydroxide. More preferably, it will be sodium hydroxide.
- homologue of glycerol is meant a superior homologue such as butantriol, pentantriol and similar.
- glycerol a propanetriol different from 1,2,3-propanetriol, such as 1,1,2-propanetriol or 1,1,3-propanetriol.
- the medium will preferably be glycerol.
- the glycerol may, at least partially, salify thanks to the action of the hydroxide. Therefore, the term "glycerol”, as used herein, can comprise glycerol in the true sense of the word, its mono-, bi and tribasic salts and mixtures thereof.
- the glycerol and the alkali metal or alkaline earth metal hydroxide will be present in the detergent composition of the invention in ratios ranging between 1 : 4 and 4 : 1.
- the detergent composition will contain alkali metal or alkaline earth metal hydroxide in weight amounts ranging between 20% and 50%, more preferably between 22% and 30% and glycerol in weight amounts ranging between 10 and 55%, more preferably between 10% and 40%.
- additives may optionally be present, such as, surfactants, water softeners such as tripolyphosphates, other sources of alkalinity, colouring agents and inorganic cation complexants.
- Other possible additives will be selected from builder, viscosing agents, anti-redeposition agents, enzymes, oxidising or reducing bleach liquors, foam reducing agents, antimicrobe agents, perfumes and others.
- Such additives absolutely conventional, can be used alone or in blends and in amounts dictated by the single requirements, as is well known to a man skilled in the art.
- surfactant can be used in the composition of the invention, such as anionic, non-ionic, cationic or amphoteric surfactants.
- non-ionic surfactants will be used, optionally in combination with hydrotrope surfactants, such as sodium xylensulfonate (commercial product SX 93% powder).
- hydrotrope surfactants such as sodium xylensulfonate (commercial product SX 93% powder).
- the use of surfactants is required in the case in which the detergent composition of the invention must be for example used either in industrial laundries or as a detergent for industrial floor washing; typically, but not always, it is used in lower amounts or can be eliminated in the application in dishwashers.
- the composition of the invention will contain surfactants, such additives will be present normally in amounts of between 0.2 and 2% by weight. It is not however excluded the use of hypersurfactant compositions, containing up to approximately 30% by weight of surfactants.
- composition of the invention will be used as an industrial detergent for laundries, it will contain an amount of surfactants ranging between 10% and 30% by weight, together with other additives such as optic bleach liquors (0.1-0.3% by weight) and carboxymethylcellulose (0.5-1.5% by weight). If however the composition of the invention will be used as a concentrated floor cleaner, it will contain between 1% and 10% of surfactants.
- Preferred tripolyphosphates will be sodium tripolyphosphates.
- the tripolyphosphates will generally be used in amounts ranging between 1% and 23% by weight.
- metasilicates or orthosilicates As additional sources of alkalinity, metasilicates or orthosilicates, phosphates, carbonates, sodium or potassium sesquicarbonates or bicarbonates, sodium and potassium borates and metaborates, amines such as mono-, di- and tri-ethanolamine may be used.
- Preferred metasilicates or orthosilicates will be sodium or potassium metasilicate or orthosilicate.
- Preferred phosphates will be alkali metal phosphates, condensed or cyclic phosphates, pyrophosphates.
- Such additional sources of alkalinity will generally be used in amounts ranging between 5% and 15% by weight.
- the inorganic cation complexants are preferably selected among salts of: 2-phosphanobutane-1,2,4-tricarboxylic acid (PBTC), N-hydroxyethylamine diacetic acid, nitrilotriacetic acid (NTA), ethylenediamine tetracetic acid (EDTA), N-hydroxyethylaminetriacetic acid (HEDTA) and diethylenetriaminepentacetic acid (DTPA).
- PBTC 2-phosphanobutane-1,2,4-tricarboxylic acid
- NTA nitrilotriacetic acid
- EDTA ethylenediamine tetracetic acid
- HEDTA N-hydroxyethylaminetriacetic acid
- DTPA diethylenetriaminepentacetic acid
- Other possible inorganic cation complexants will be selected from water soluble acrylic polymers, such as polyacrylic acid, polymethacrylic acid and their copolymers, hydrolised polyacrylamide, hydrolised polyme
- Such polymers will be used in a molecular weight range between 4000 and 12000, more preferably between 4000 and 8000.
- Sodium polyacrylate with a molecular weight ranging between 4000 and 8000 is the preferred variety.
- complexant agents phosphates such as those listed above may also be employed.
- Particularly preferred inorganic cation complexants will be ethylenediaminetetraacetic acid (EDTA) or nitrilotracetic acid (N,N-bis(carboxymethyl)glycine, NTA) or blends thereof in a NTA/EDTA ratio of 3:1 - 1:15.
- EDTA ethylenediaminetetraacetic acid
- NTA nitrilotracetic acid
- Said complexant will be present in the detergent composition of the invention in amounts ranging between 5% and 40%.
- composition of the invention will be able to contain secondary solidifying agents or solubility modifiers, such as an amide (stearic acid monoethanolamide or lauric acid diethanolamide), an alkylamide, a solid polyethylene or polypropylene glycol, amides modified and made water soluble by treatment with acids or bases.
- secondary solidifying agents or solubility modifiers such as an amide (stearic acid monoethanolamide or lauric acid diethanolamide), an alkylamide, a solid polyethylene or polypropylene glycol, amides modified and made water soluble by treatment with acids or bases.
- Such solidifying agents will be present in the composition of the invention in weight amounts of between 5% and 20%, preferably between 10% and 15%.
- the detergent composition of the invention is obtained according to the method described below.
- a suspension of the medium (glycerol and/or a homologue or isomer thereof) is prepared with the optional additives, preferably selected from those listed above, and this suspension is heated to a temperature that may range between 50°C and 100°C. In this way the blend is maintained in a fluid state.
- the alkali metal or alkaline earth metal hydroxide preferably in beads or in a solid state.
- An exothermia of the blend occurs and, after about 10 - 15 minutes, a more rigid mass is formed, that within 24 hours can be defined solid agglomerate. In the period elapsing between the addition of the hydroxide and hardening it is necessary to complete the transfer of the detergent composition into the final use containers.
- Such containers will be generally applied to washing machines or dishwashers fitted with dissolution devices that use water jets directed towards the detergent.
- the water jet dissolves the necessary amount of detergent composition that is thus made available for the washing.
- the still fluid blend of the invention composition can be transferred into suitable moulds until solidification and then transferred into water soluble containers, such as, for example, sachets.
- water soluble containers such as, for example, sachets.
- water soluble plastic sachets, water soluble films, paper and cardboard may be used. This enables to introduce the thus wrapped inventive composition directly into the funnel doser of the dishwasher.
- the invention composition can also be extruded, when still in its plastic phase, so as to form small pieces, such as small bricks or spheres, to be wrapped in water soluble packaging as described above.
- the reaction occurs with high exothermicity.
- the detergent composition allows to overcome the disadvantages inherent to prior art industrial detergents.
- the solid mass is in the form of a single block and thus does not require the presence of holding nets or septums on the mouthpiece of the use container.
- the detergent of the invention thanks to the fact that it is a solid, can contain high amounts of caustic hydroxide, thus resulting in a better cleaning effect.
- glycerol has, together with the inorganic cation complexants, a control effect on the hardness of the water and provides anticorrosive and detergent properties to the composition.
- the detergent composition according to the invention can be used in various sectors, such as an alkylating agent or detergent in milking machines, or as an industrial detergent for laundries or for cleaning floors, with small modifications to the composition within the claimed ranges.
