Definitions

• This invention refers to a new detergent composition and the means which comprises it.
• the invention refers to a composition suitable for cleaning dishes and those surfaces in the domestic environment which require great effectiveness whilst respecting the surfaces, without scratching or removing layers and/or coatings.
• Means commonly used for cleaning dishes such as sponges, cloths, etc. mainly consist of more or less abrasive fibres that, in proportion to their cleaning ability, result in either being excessively delicate and therefore unsuitable for effective cleaning and removal of dirt, or so abrasive as to entail the alteration of the surfaces to be cleaned, by causing, for instance, scratches, grazes, removal of any protective coatings possibly present, etc., respectively.
• dish cleaning means which comprises detergent compositions, basically consisting of polyurethane resins, particularly suitable for cleaning dishes with delicate surfaces, easy to scratch or having coating or nonstick layers, etc.
• a detergent composition comprising a resin and a powder has unexpectedly been identified which allows to obtain an accurate cleaning, even on the most delicate surfaces, without scratching or affecting the external protective or nonstick coatings.
• the peculiar association comprised in the composition of the invention allows many types of resin, including polyurethanes, to be used to advantage.
• the composition of the invention comprises a resin selected from the group consisting of neoprene, phenol, polyester, acrylic, vinyl, urea, polyurethane, epoxy and epoxy-polyurethane resins.
• the neoprene resins can be, for example, of the Klebofix type produced by Kleboplast
• the phenol ones can be, for example, of the Special type produced by Impla Resine
• the polyester ones can be, for example, of the Roskidal 500 type produced by Bayer
• the acrylic ones can be, for example, of the Novaflex type produced by Ceca Ato
• the vinyl resins can be, for example, of the type of Protovil or Deltavil or Protostik produced by Concorde
• the urea ones can be, for example, of the type of Protodur produced by Concorde
• the polyurethane ones can be, for example, of the type of Idropur, Tecnopur or Protopur produced by Concorde
• the epoxy resins can be, for example,
• the powder comprised in the composition of the invention is selected from the group consisting of polypropylene, polythene, polystyrene and polycarbonate powders, maize flour, wood and polyvinylchloride powders; the average sizes of the particles forming the powder are comprised in the range between 150 and 750 microns.
• the quantity of the resin in the composition of the invention is preferably comprised between 70 and 95% by weight, whereas the quantity of the powder is comprised between 5 and 30% by weight.
• the new composition may comprise an abrasive, amounting to 0.1 to 0.8% by weight, selected from the group consisting of sand, quartz, pumice stone powder, silica, aluminum oxide and magnetite.
• composition of the invention may also comprise an excipient; in particular, a scent and a colour, each in a quantity comprised between 0.8 and 4.5%.
• the colour used in the composition of the invention may be vegetable, organic or mineral; the scent can be an essential oil, an extract or a concentrate.
• composition of the invention may also comprise other excipients such as talc, silica gel, calcium carbonate and grain flour.
• Another subject of the invention is a means for cleaning, for dish cleaning in particular, which comprises the composition of the invention.
• the support on which the composition of the invention is applied may be of any type, natural or synthetic, among those normally used in the field, such as sponges, cloths etc., for example.
• composition of the invention may be applied on the support using any of the methods commonly used in the field, such as spraying, for example.
• Protopur 100 g of Protopur, a polyurethane resin produced by Concorde, were mixed with 20 g of Tecmastir, a polystyrene powder produced by Tecma. 2 g of lemon scent (essential oil) and 2 g of yellow chrome powder were separately mixed and then added to the resin/powder mixture.
• Protopur 120 g of Protopur, a polyurethane resin produced by Concorde, were mixed with 18 g of Tecmastir, a polystyrene powder produced by Tecma, and 12 g of talc.
• 2.4 g of lemon scent (essential oil) and 2.4 g of yellow chrome powder were separately mixed and then added to the resin/powder/talc mixture.
• Protovil a polyvinyl resin, produced by Concorde, were mixed with 25 g of wood powder. 2.5 g of pine scent (extract) and 2.5 g of red colour were separately mixed and then added to the resin/powder mixture.
• the mixture was allowed to burn until completely carbonised, eliminating the dry residual and carrying out the test on the remains attached to the sheets.
• the sheets were subsequently immersed in water and scrubbed with a cleaning means comprising the composition of the invention so as to simulate domestic cleaning.
• Abrasion was determined by counting the number of cycles the device performs before thorough cleaning is achieved, evaluated both visually and by touch.
• the test includes 1000 passes of the cleaning means on the sheets with a frequency of 120 passes/min for a period of approximately 8 minutes.
• the results are supplied in the table below, where the compositions of the invention are compared with cleaning means available on the market, respectively comprising non abrasive fibres, abrasive fibres and a polyurethane resin.
