Definitions

  • the invention relates to a detergent package combination, and in particular to a detergent tablet - package combination.
  • Detergent - package combinations are described in, for example, W095 02681, which relates to a combination of a granular detergent composition which is contained in a packaging system having a moisture vapour transmission rate, hereinafter MVTR, of less than 20 g/m 2 /24 hours.
  • MVTR moisture vapour transmission rate
  • WO 95/18215 describes a detergent article comprising a detergent mass of at least 100 g, typically 2 Kg to 5 Kg, having a barrier layer coating to prevent absorbtion of water.
  • the teaching of this document is directed towards cast blocks of detergent material which, if unprotected, absorb large quantities of water rendering the blocks soft and malleable.
  • the present invention is directed towards the provision of an improved detergent-package combination which provides improved physical and functional characteristics, for the detergent contained within the package .
  • a co bination of at least one tablet of compacted particulate detergent composition stored for at least 24 hours within a closed packaging system having a moisture vapour transmission rate of less than 20g/m 2 /24 hours.
  • the MVTR of the packaging system is less than 10 g/m 2 /24 hours, ideally approximately 5 g/m 2 /24 hours.
  • the detergent composition comprises either (a) a sodium tri- polyphosphate composition, or (b) a sodium acetate trihydrate composition optionally together with sodium citrate dihydrate.
  • these components have been found to be highly effective disintegrants which, while allowing the tablets to be compressed to produce a tablet of increased strength, allow a rapid disintegration of the tablet in water.
  • the detergent composition comprises phase I sodium tripolyphosphate which has been found to be a particularly effective disintegrant .
  • the detergent composition comprises at least one tablet of a compacted particulate composition wherein the tablet or a region thereof comprises from 2% to 35% by weight of a salt which is sodium acetate trihydrate, potassium acetate or mixture thereof, optionally together with sodium citrate dihydrate, such that the total quantity of sodium acetate trihydrate, potassium acetate and sodium citrate dihydrate is from 7% to 50% by weight of the tablet or region thereof.
  • the tablet may contain 15% to 93% of a water softening agent.
  • the detergent composition comprises a tablet of compacted particulate detergent composition, containing one or more detergent-active compounds together with sodium tripolyphosphate and other ingredients, characterised in that the tablet or a region thereof comprises particles which contain sodium tripolyphosphate with a content of the phase I form which is more than 40% by weight of the sodium tripolyphosphate in the particles, wherein the sodium tripolyphosphate in said particles contains water of hydration distributed throughout the tripolyphosphate in an amount between 1% and 5% by weight of the sodium tripolyphosphate in the particles.
  • the detergent composition is stored in the packaging system for at least 1 week, preferably at least 2 weeks, more preferably at least 3 weeks, ideally at least 4 weeks.
  • the packaged detergent composition is stored for up to 8 weeks, and often for even greater than 8 weeks .
  • the packaging system will advantageously have a reasonable oxygen permeability, ideally not greater than 2000 cm 3 /m 3 /24 hours.
  • the packaging system comprises a material having a bulk density of less than 40g/m 2 .
  • the packaging system comprises a polymeric film, preferably an oriented polypropylene film. Suitable films are sold under the trademark BICOR.
  • the packaging system may comprise a PET/PE laminate, preferably having a thickness of approximately 12 micron PET/40 micron PE .
  • the detergent composition is wrapped in a flow-wrap sealed polymer- based packaging system such as those described above.
  • Suitable packaging systems are the films sold under the trade name BICOR having the following codes:- MB 668,
  • MB 666 MB 600, MB 450, MB 400, MD 447, MH 648, MW 648, MH 647 and MW 647.
  • the invention also provides a process for preparing a packaged detergent composition comprising the steps of:- placing at least one tablet of compacted particulate detergent composition in a packaging system having a MVTR of less than 20 g/m 2 /24 hours;
  • the tablets comprise particulate detergent composition compacted with a force of at least 3N, typically greater than 4N, ideally greater than 5N and most preferably greater than 6N.
  • a ratio of the DFS (KPa) to the T 90 (mins) for the tablets is greater than 1, ideally greater than 2.
  • the combination comprises two sodium tripolyphospohate containing detergent tablets flow wrapped in sealed oriented polypropylene wrapping of the type sold under the trade mark BICOR MB 668.30, and stored for different periods of time under specific conditions of temperature and humidity.
  • BICOR MB 668.30 the type sold under the trade mark BICOR MB 668.30
  • composition and manufacture of the tablets is given below.
  • Tablets for use in fabric washing were made, starting with a spray-dried base powder of the following composition:
  • compositions thus contained the following percentages by weigh .
  • the packaging system comprised a sealed flow-wrap oriented polypropylene system sold under the trade mark BICOR MB 668.30.
  • BICOR MB 668.30 The properties of this material are given in Table l.A below: -
  • ⁇ is the diametral fracture stress in Pascals
  • P is the applied load in Newtons to cause fracture
  • D is the tablet diameter in metres
  • t is the tablet thickness in metres.
  • the break-up, dispersion and dissolution of tablets was measured by a test procedure in which a tablet is placed on a plastic sieve with 2 mm mesh size which was immersed in 9 litres of demineralised water at ambient temperature of 22°C and rotated at 200 rpm. The water conductivity was monitored until it reached a constant value.
  • the time for break up and dispersion of the tables was taken as the time (T 90 ) for change in the water conductivity to reach 90% of its final magnitude. This was also confirmed by visual observation of the material remaining on the rotating sieve.
  • the same combination is used as that of example 1 with the exception that the detergent composition comprises a sodium acetate trihydrate composition made according to the protocol below.
  • Tablets for use in fabric washing were made, starting with a base powder of the following composition:
  • Nonionic detergent 3 25.9%
  • the coconut alkyl sulphate was incorporated as preformed granules containing 45% coconut alkyl sulphate, 35% zeolite, 11% sodium carbonate, balance water and other salts.
  • Ci3_i5 fatty alcohol 7EO This powder was mixed with sodium acetate trihydrate (from Merck as used in Example 1) and other detergent ingredients as tabulated below.
  • compositions thus contained:
  • 35g portions of each composition were made into cylindrical tablets of 44 mm diameter, using a Carver hand press with various levels of compaction force.
  • ⁇ is the diametral fracture stress in Pascals
  • P is the applied load in Newtons to cause fracture
  • D is the tablet diameter in metres
  • t is the tablet thickness in metres.
