Definitions

  • This invention relates to an environmental friendly detergent composition useful in a gel for cleaning hard surfaces.
  • high pressure foam cleaning In industry hard surface cleaning has traditionally been carried out by high pressure foam cleaning. There are some severe safety and environmental problems by using high pressure foam cleaning such as high pH, aggressive cleaning agents, high water consumption, aerosol formation and mechanical noise.
  • the gel cleaners have the advantages of giving no or insignificant aerosol formation, they have a low water consumption, and they are easy to apply: Prior to dilution the gel compositions are readily mobile liquids which are convenient for transport etc., but when diluted to working concentrations they start to thicken to a gel-like consistency, which mean that they will remain in contact with the surface or object to be cleaned for sufficient time to enable the cleansing to occur (for reference see EP 0 314 232) , so if the detergents of the gel composition are environmental friendly, the gel application method is a very safe and gentle way of cleaning hard surfaces.
  • a gel can be made of very environmental friendly chemicals, namely glycolipid, polyalcohols and water. Accordingly, the present invention relates to a liquid detergent composition which undergoes a viscosity increase upon aqueous dilution, comprising a) one or more glycolipids b) one or more polyalcohols c) water.
  • a gel cleaning composition can be made of glycolipid(s) , poly- alcohol(s) and water.
  • the glycolipid may be a sugar or sugar alcohol fatty acid ester (as described in JP 63- 112,993) or a derivative thereof or a fatty acid monoester or a mixture of fatty acid monoesters of alkylglycoside (as described in US 5,191,071 and in US 5,200,328) or a derivative thereof.
  • the glycolipid is a fatty acid monoester of ethylglycoside, the fatty acid containing 8-22 carbon atoms, e.g. ethyl 6-O-dodecanoyl glucoside.
  • any polyalcohol which has two or more hydroxyl groups may be used in making the gel.
  • Useful examples are 1,2-ethanediol, 1,2-propandiol, 1,3- propandiol, 1,2,3-propantriol, butanediols, butanetriols, pentanediols, and sugar alcohols.
  • 1,2-propandiol is preferred.
  • the gel composition may optionally also contain other detergent ingredients such as solvents and sequestrants.
  • the gel composition may also contain an electrolyte (e.g. sodium chloride) . It has been found that sodium chloride should be added in more than 8 % w/w in order to maintain the gel formation when the gel components are ethyl 6-0-dodecanoyl glucoside, 1,2-propandiol and water (in lower concentrations the gel formation decreases, for reference see Example 1).
  • an electrolyte e.g. sodium chloride
  • the gel composition may also contain one or more enzymes.
  • the enzymes are in particular proteases (for instance Savinase* 16.0 L, Alcalase* 2.5 L, Esperase* 8.0 L or DurazymTM 16.0 L, all available from Novo Nordisk A/S) , amylases (for instance Termamyl* 300 L available from Novo Nordisk A/S) , lipases (for instance Lipolase* 100 L available from Novo Nordisk A/S) or cellulases (for instance Celluzyme 11 ' 1.0 L available from Novo Nordisk A/S) .
  • the amount of enzyme may be dosed so that the percentage of enzyme in the finished gel will be of 0.001-10%, preferably 0.01-1%, in particular about 0.01- 0.5%.
  • the gel is made in situ.
  • the detergent composition comprising the glycolipid(s) and the polyalcohol(s) are diluted with water and applied to the soiled surfaces by using some kind of application system (e.g. diluted through a venturi and applied via a special lance) .
  • the detergent composition is best applied using gel generation equipment which automatically draws in the required percentage.
  • the required percentage of a given glycolipid and a given polyalcohol may be found as described in Example 1.
  • Application equipment is available from for instance Scanio A/S, Blytaekkervej 4-6, DK-9000 Aalborg, Denmark.
  • the gel is applied to the soiled surfaces as described above.
  • the gel will set on the surfaces within a few seconds.
  • the gel will remain in its form even on complicated shaped equipment, vertical surfaces and ceilings and will therefore give very long contact times. Dwell times are difficult to estimate beforehand and should be determined by trial. A dwell time of 5-30 minutes may often be required.
  • the gel composition is rinsed off using a washing system.
  • a washing system In some cases it may be necessary to use a pressure washing system to rinse off the gel composition, but often removal by gentle flushing with water is easy and all that is needed.
  • the cleaning gel detergent described in this inven ⁇ tion may be used in all kinds of industries: in dairies, in slaughterhouses, in breweries, in sea food production units etc. It may also be used in the transport sector, for instance as a cleaning agent in car washing and for general vessel wash. Especially, the cleaning gel may be useful in removing oils (vegetable, animal and mineral) . It may also work as a general purpose cleaner in households, e.g., for cleaning windows, bathrooms and kitchens, in particular it may be useful as an efficient oven cleaner. It may also be useful for janitorial purposes such as computer cabinet cleaning etc.
  • the cleaning gel of the present invention may also be very useful for personal care purposes, in skin, hair and dental applications, such as cleaning dentures.
