Definitions

  • the present invention relates to detergent compositions, in particular to structured liquid detergent compositions.
  • Liquid detergent compositions offer several advantages over granular detergent compositions. For example, liquid compositions are easy to dose and give confidence to the consumer of being safe to the fabrics. This may be the reason why heavy duty and light duty built laundry liquid detergent products have gained a great popularity ever since their introduction on the market.
  • Isotropic liquids are liquids in which all ingredients are dissolved and, contrary to structured liquids, there is no structure present in isotropic liquid.
  • structured liquids may be brought about to endow properties such as consumer preferred flow properties and/or turbid appearance. Many structured liquids are also capable of suspending particulate solids. Examples of structured liquids are given in US-A-4244840, EP-A-0160342, EP-A-0038101 and EP-A-0140452. Structured liquids can be "internally structured", whereby the structure is formed by primary ingredients, preferably by surfactant material, and/or “externally structured” whereby a three dimensional matrix structure is provided by using secondary additives, preferably polymers, clay, silica and/or silicate material. Externally structured liquids may provide a high viscosity upon storage.
  • the degree of ordering of surfactant containing systems increases with increasing surfactant and/or electrolyte concentrations.
  • the surfactant can exist as a molecular solution, or as a solution of spherical micelles, both of these solutions being isotropic, i.e. they are not structured.
  • further surfactant and/or electrolyte structures of surfactant material may form.
  • Various forms of such structures exists, e.g. bi-layers. They are referred to by various terms such as,rod-micelles, anisotropic surfactant phase, planar lamellar structures, lamellar droplets and liquid crystalline phases.
  • a preferred lamellar structure is characterised by lamellar droplets of surfactant material in an aqueous continuous phase wherein the dispersed structuring phase is generally believed to consist of an onion-like configuration comprising concentric bilayers surfactant molecules, between which water is trapped, the aqueous phase.
  • Liquids with a lamellar droplets structure are preferred as systems in which such droplets are close-packed providing a very desirable combination of physical stability with useful flow properties, i.e., good pourability combined with adequate stability.
  • Such liquids have, for example, been described in A. Jurgens, Micro-structure and Viscosity of Liquid Detergent, Tenside Surfactants Detergent 26 (1989), page 222 and J.C.
  • a surfactant structuring system in a liquid may be determined by means known to those skilled in the art for example, optical techniques, various rheometrical measurements, X-ray or neutron diffraction, and sometimes, electron microscopy.
  • liquid detergent compositions which are chemically and physically stable, especially upon storage.
  • Such detergent compositions may become inhomogeneous, e.g. ingredients may separate out by crystallisation or precipitation.
  • Another aspect of liquid detergents is their dissolution behaviour.
  • dissolution behaviour is Another aspect of liquid detergents.
  • a detergent composition When a detergent composition is used, consumers prefer to see it rapidly dissolve in water. This assures the user that the detergent composition quickly becomes fully active. Structured liquid detergent compositions already dissolve more rapidly than powdered detergents. But for liquid detergent compositions that may be used for hand-wash applications including laundry, an excellent dissolution behaviour is required.
  • structured liquid detergent compositions are capable of suspending solids such as zeolite.
  • Such compositions pose significant problems with regard to rheology and stability because the solids should remain suspended over at least 1-3 weeks while the compositions should remain pourable.
  • suspension of solids is not always needed.
  • Structured liquid detergents that do not contain stably suspended solids may then be preferred because these compositions do not have to fulfil such stringent requirements and may therefore be easier to formulate.
  • most prior art is related to structured liquids having stably suspending solids.
  • EP-A-301 882 discloses structured liquid detergent compositions having stably suspended solids such as 20 wt% zeolite. The dissolution behaviour of the compositions is not disclosed.
  • EP-A-362 916 relates to the incorporation of high levels of a functional polymer to counteract the effects of fabric softening clays. The compositions exemplified are capable of suspending solids. The dissolution behaviour of the resulting compositions is unclear.
  • EP-A-829 530 describes structured hard surface cleaning compositions contain stably suspended solids. It contains no disclosure regarding the dissolution behaviour of the exemplified compositions.
  • EP-A-74 134 discloses structured liquid detergent composition having stably suspended solids.
  • sodium sulphite can be used in compositions with high levels of sodium triphosphate (25 to 26%) if sodium xylene sulphonate or sodium toluene sulphonate is used to obtain the right viscosity and good stability. Again, there is no disclosure on the dissolution behaviour of the disclosed compositions.
  • the present invention relates to a stable, structured liquid detergent composition wherein:
  • compositions with stably suspended solids are compositions that are able to suspend 20 wt% of zeolite 4A for 3 wks at 25°C under normal pressure without showing more than 2% of an upper layer which contains less zeolite than the bottom layer.
  • Yet another embodiment provides for a process to clean laundry using a liquid detergent composition according the present invention.
  • the relatively low dissolution rate of aqueous structured liquid detergent compositions may be a major consumer-perceived drawback.
  • a high dissolution rate may assure the consumer that the liquid detergent composition is properly dissolved and therefore completely active. This applies in general to all liquid detergent compositions but in particular for liquid detergent compositions that are suitable for hand wash applications.
  • a favourable dissolution rate is when the Dissolution Time (as measured below) is less than 120, preferably less than 100, more preferably less than 90, more preferably less than 80, even more preferably less than 60 seconds.
  • 10 ml liquid detergent is dosed with a regular flow via a syringe to a beaker of 3 litre (diameter 14 cm) filled with 2.5 litres of water of 4 °FH at 25 °C.
  • the water in the beaker is stirred with a magnetic stirrer (rod of 6 cm length) in such a way that a vortex of 1 cm is formed in the centre of the beaker.
  • the liquid detergent is dosed outside the vortex.
  • the electrical conductivity is recorded as function of time, 1 cm from the wall of the beaker till constant reading (all liquid detergent is dissolved). From the data the Dissolution Time is calculated by taking the time to reach 90% of the equilibrium conductivity value, i.e., when 90% by weight of the composition is dissolved.
  • the composition of the present invention comprises Viscosity Reducing Polymer as described in EP-A-0301882.
  • the Viscosity Reducing Polymer is able to reduce the viscosity of the composition by more than 5% when measured at a shear rate of 21 S -1 , in comparison with an identical composition except that all such polymer is omitted.
  • a number of different polymers may be used, provided the electrolyte resistance and vapour pressure requirements are met.
  • the former is measured as the amount of sodium nitrilotriacetate (NaNTA) solution necessary to reach the cloud point of 100 ml of a 5% solution of the polymer in water at 25°C, with the system adjusted to neutral pH, i.e. about 7.
  • the polymer preferably has a vapour pressure in 20% aqueous solution equal to or less than the vapour pressure of a reference 10% by weight aqueous solution of polyethylene glycol having an average molecular weight of 6000. It needs to be emphasised that, in contrast to the present invention, EP-A-0301882 discloses how to use Viscosity Reducing Polymer to improve the pourability of the liquids (page 2, line 43) without mentioning possible effects on the dissolution behaviour.
  • the composition according the present invention comprises more than 0.01%, preferably more than 0.05%, more preferably more than 0.1% and less than 10%, preferably less than 5%, more preferably less than 2.5% by weight of Viscosity Reducing Polymer.
