Description
"A Cleaning and Sanitising Composition"
The invention relates to a composition for cleaning and sanitising purposes.
According to the invention there is provided a cleaning and sanitising composition in tablet form comprising a disinfecting or sanitising agent, a surfactant and a base material which are formed into a tablet by a dry compression process.
The tablet may also include a water softening, sequestering agent or soil suspension agent/builder.
In one embodiment of the invention the sterilising agent is a halogen source, preferably a chlorine and/or bromine source.
Where the sterilising agent includes a chlorinating agent preferably the chlorinating agent is a chlorinated isocyanurate which may be present with or without an added bromine source.
Typically the disinfecting or sanitising agent is present in an amount of between 2.5 and 60% by weight of the tablet.
In a particularly preferred embodiment of the invention the tablet includes an admixture of polyethylene glycol and sodium lauryl sulphate which provides exceptional cohesive and lubricant properties to enable the manufacture of tablets by direct compression methods, without any pretreatment (eg wetting, drying, emulsifying, granulating) of any of the tablet components. It has been found that an admixture of powdered sodium lauryl sulphate, with an active matter of approximately 89% (mmw303) when mixed with polyethylene glycol, of an average molar mass between 1300 and 3,700 and more preferably 1500, in a ratio of between 0.1:1 and 1.5:1 and more preferably 0.9:1 provides a tablet of excellent physical characteristics when pressed on high speed rotary tabletting machines, without any picking, dragging, chipping, capping or laminating of the tablet.The two materials are also compatible with each other and other active tabletting materials such as the chlorinated isocyanurates, sequestering agents and soil suspension agents, and also with effervescent bases. The mixture of sodium lauryl sulphate and polyethylene glycol will typically comprise between 5% and 80% of the finished tablet weight and preferably between 50% and 70% for non-effervescent tablets and 25% to 35% for effervescent tablets.
In another embodiment the tablet includes an admixture of a high active, predominantly straight chained alkyl benzene sulphonate and a natural source material derived from defatted soya beans, typically containing 80% high molecular weight polysaccharides when blended together with other materials which may include sequestering agents, chlorinated isocyanurates and an effervescent base, are compressible by direct compression means without any pretreatment (eg wetting, drying emulsifying, granulating) of any of the tablet components. The tablets are of excellent physical characteristics when pressed on high speed rotary tabletting machines, without any picking, dragging, chipping, capping or laminating of the tablet. The two materials are compatible with each other and are also compatible with the other tabletting materials.The mixture of the alkyl benzene sulphonate and the material derived from defatted soya beans will comprise of between 5% and 808 and preferably between 15% and 30% of the finished tablet.
In one embodiment of the invention the composition includes a sequestrant in combination with a surfactant. Preferably the sequestrant comprises sodium tripolyphosphate. Most preferably the tripolyphosphate is present in an amount of approximately 10% by weight.
In a preferred embodiment of the invention the weight ratio of the disinfecting or sanitising agent to the surfactants is from 10:1 to approximately 1:10.
In one embodiment of the invention the base is noneffervescent. In another embodiment of the invention the base is effervescent. The rate of effervescence and solubility may be controlled by variation of the effervescent base components, by weight. The base material may comprise anhydrous alkali metal sulphate such as anhydrous sodium sulphate which may be present in an amount of from 2% to 15%, most preferably approximately 5% to 10% by weight. Preferably the base material also includes an alkali metal bicarbonate, particularly sodium bicarbonate which is present in an amount typically of between 5% and 30% most preferably approximately 20% to 28% by weight.
Preferably, the base also includes an acid source which is typically between 5% and 30%, most preferably approximately 18% to 26% by weight of the tablet. The acid may comprise adipic acid or a combination of fumaric acid and maleic acid in a weight ratio from 6:1 to 1:1.
The invention will be more clearly understood from the following description thereof given by way of example only.
EXAMPLE A
To form a tablet having both disinfecting or sanitising and surfactant properties, the following ingredients are mixed together and subsequently compressed into tablet form.
No pretreatment of any of the materials, other than the mixing of the dry materials, is necessary prior to compression.
A tablet without an effervescent base material was formed by mixing the following ingredients and compressing then using a dry compression process.
Sodium dichloroisocyanurate 1.70 kg
Sodium lauryl sulphate 0.12 kg
polyethylene glycol 0.17 kg
Sodium tripolyphosphate 0.01 kg
A batch of tablets of 20 grams weight was produced from these ingredients.
The change in pH when the tablets were added to tap water at a pH of 6.81 and a temperature of 14"C was monitored and the following results obtained.
TIME
(minutes) pH
0 6.81
10 5.72
20 5.64
30 5.62
40 5.63
The tablets had a hardness of at least 15kg were approximately 15mm thick and had a finished weight of approximately 20 grams.
EXAMPLE B
A tablet having an effervescent base may be formed from the following ingredients:
sodium dichloroisocyanurate 42.7% by weight
sodium lauryl sulphate 8.2% by weight
polyethylene glycol 6.0% by weight
sodium tripolyphosphate 0.3% by weight
adipic acid 18.8% by weight
anhydrous sodium sulphate 4.3% by weight
sodium bicarbonate 19.7% by weight
The ingredients may be mixed and then compressed together by a direct compression process without the use of any pretreatment, other than the mixing of the dry materials, prior to compression
Instead of adipic acid, a combination of fumaric acid and maleic acid to a total percentage of approximately 18% to 26% by weight may be used. The use of fumaric acid as an aliphatic carboxylic acid in the composition produces a tablet having an acceptable appearance, and having suitable properties regarding storage and solution time.However, fumaric acid alone generally requires a long reaction time.
The addition of maleic acid however, produces a synergistic effect and allows the reaction to proceed more vigorously.
Thus, a controlled effervescent and solution time can be achieved by using a combination of fumaric and maleic acid.
The anhydrous alkali metal sulphate particularly sodium sulphate acts as a pH buffer and also acts as a water scavenger and so reduces the sensitivity of the tablets to moisture so that they can be stored for long periods without degradation. The sodium sulphate will also assist soil suspension.
Sodium lauryl sulphate and polyethylene glycol act as surfactants and also as binding and lubricating agents.
EXAMPLE C
A tablet having an effervescent base may be formed from the following:
% bv weight
Sodium dichloroisocyanurate 5.25%
Sodium dodecyl benzene sulphonate 18.50%
Sodium tripolyphosphate 7.508 Sodium bicarbonate 27.008 Sodium sulphate 11.00%
Adipic Acid 25.75%
Emcosoy (by Mendell) 5.00%
The ingredients may be mixed together and then compressed together by a direct compression process without the use of any pretreatment, eg wetting, emulsifying, drying, granulating, prior to compression. The above tablets were 4gms finished weight and displayed excellent physical characteristics with no chipping, capping, dragging picking or laminating, with a hardness greater than 8kg. Dissolution was achieved in 5 mins to 8 mins in water of between 40"C and 250C without agitation.The pH of the resultant solution of one tablet in 2.5 litres was approximately 5.8 after 15 mins. The solution produced a high foam suitable for catering use (for example) without streaking of glassware or crockery.
EXAMPLE D
Sodium dichloroisocyanurate 10% by weight
Sodium dodecyl benzene sulphonate 22% by weight
Sodium tripolyphosphate 10% by weight
Adipic Acid 25.4% by weight
Sodium bicarbonate 26.6% by weight
Sodium sulphate 5.8% by weight
Tartrazine (colour) 0.2% by weight
The ingredients were dry blended and then compressed together on a high speed rotary press by a direct compression method process without the use of any pretreatment such as wetting, emulsifying, drying or granulating, prior to coupression.
Tablets were compressed using 15.8mm punches to a finished weight of 1 gramme without any chipping, capping, dragging, picking or laminating. A hardness of greater than 6kg was achieved and a dissolution of less than 5 minutes in 280mls ( pint) at 40"C to 45 C.
The sodium dichloroisocyanurate provides at least 200ppm available chlorine in hand held spray guns of 280my capacity used for hard surface disinfection in the catering/janitorial segments. The inclusion of a compatible surfactant (sodium dodecyl benzene sulphonate) and sequestrant (sodium tripolyphosphate) allows the disinfecting and cleaning in a one step operation in a uniform dosage form.
EXAMPLE E
Sodium dichloroisocyanurate 5.158 by weight
Sodium dodecyl benzene sulphonate 17.18% by weight
Sodium hexametaphosphate 0.17% by weight
Sodium tripolyphosphate 9.81% by weight
Emcosoy (by Mendell) 4.42% by weight
Adipic Acid 27.848 by weight
Sodium bicarbonate 29.10% by weight
Sodium sulphate 6.33% by weight
As before, the ingredients were dry blended and compressed on a high speed rotary compression machine by a direct compression process, without any pretreatment. The tablets were compressed to a finished weight of 8 grammes, using 25mm punches. Tablets of excellent physical properties were produced.
The sodium dichloroisocyanurate provides at least 50ppm available chlorine in 4 litres of water. The sodium dodecyl benzene sulphonate and sodium hexametaphosphate combine to produce sufficient detergency for washing crockery for example, and retaining good foam stabilisation. Sodium tripolyphosphate provides sequestration. The unit dose format provides for disinfection and detergency in a uniform, one step operation.
