Definitions

  • the present invention relates to stable concentrated liquid detergent compositions containing a clay softening system. More in particular, the present invention relates to softening through the wash liquid detergent compositions comprising a clay softening system and specific modified soil release polymers.
  • Liquid detergent compositions providing fabric softening throughout the wash cycle have been described in art.
  • clays are well known as fabric softening agents through the wash.
  • the relative ability of the softening clays to meet various performance criteria is very much depending on the presence and concentration of adjunct detergent ingredients.
  • adjunct detergent ingredient is the presence of soil release polymers.
  • Said soil release polymers when used even at low concentrations, interact strongly with the clay, resulting in loss in performance of the soil-release polymer, flocculation of the clay and problems with physical stability of the liquid detergent.
  • Concentrated liquids contain a lower amount of water compared to conventional liquid detergents. This results in an increase in electrolyte and solids levels in these liquid detergent formulas.
  • Another change is the dependence on non ⁇ aqueous solvents to aid in the solubilization of detergent components.
  • liquid softening-through-the-wash detergent composition comprising a clay softening system in combination with specific modified polyesters. It has now been surprisingly found that the specific modified polyesters according to the present invention are fully compatible with the clay-softening system. This finding allows us to formulate liquid detergent compositions which have both excellent softening and cleaning performance.
  • the present invention relates to concentrated liquid detergents comprising a clay-softening system and specific modified polyesters. All percentages, ratios herein are by weight, unless otherwise specified.
  • the present invention relates to concentrated liquid detergents, in such case, the liquid detergent compositions according to the present invention will contain a lower amount of water, compared to conventional liquid detergents.
  • the level of water in the concentrated liquid detergents of the present invention is less than 50%, preferably less than 40% by weight of the total detergent composition.
  • the clay softening system hereof will comprise a fabric softening clay present in an amount of at least 0.5%, preferable from 4% to 30% by weight of the detergent composition.
  • the preferred clays are of the smectite type.
  • Smectite type clays are widely used as fabric softening ingredients in detergent compositions. Most of these clays have a cation exchange capacity of at least 50 meq./lOOg.
  • Smectite clays can be described as three-layer expandable materials, consisting of alumino-silicates or magnesium silicates.
  • smectite-type clays There are two distinct classes of smectite-type clays; in the first, aluminium oxide is present in the silicate crystal lattice, in the second class of smectites, magnesium oxide is present in the silicate crystal lattice.
  • the general formulas of these smectites are AI2(Si2 ⁇ 5)2 (OH)2 and Mg3 (Si2 ⁇ 5) (OH)2 for the aluminium and magnesium oxide type clay, respectively.
  • the range of the water of hydration can vary with the processing to which the clay has been subjected.
  • atom substitution by iron and magnesium can occur within the crystal lattice of the smectites, while metal cations such as Na + , Ca ⁇ + , as well as H + can be co-present in the water of hydration to provide electrical neutrality.
  • clays on the basis of one cation predominantly or exclusively absorbed.
  • a sodium clay is one in which the absorbed cation is predominantly sodium.
  • Such absorbed cations can become involved in equilibrium exchange reactions with cations present in aqueous solutions.
  • one equivalent weight of solution cation replaces an equivalent of sodium, for example, and it is customary to measure clay cation exchange capacity in terms of milliequivalents per lOOg. of clay (meq/100g.).
  • the cation exchange capacity of clays can be measured in several ways, including electrodialysis, by exchange with ammonium ion followed by titration, or by a methylene blue procedure, all as set forth in Grimshaw, The Chemistry and Physics of Clays, Interscience Publishers, Inc. pp. 264-265(1971).
  • the cation exchange capacity of a clay mineral relates to such factors as the expandable properties of the clay, the charge of the clay, which in turn, is determinated at least in part by the lattice structure, and the like.
  • the ion exchange capacity of clays varies widely in the range from about 2 meq/100 g.
  • Illite clays have an ionexchange capacity somewhere in the lower portion of the range, ca. 26 meq/100 g. for an average illite clay.
  • illite and kaolinite clays are not useful in the instant compositions. Indeed such illite and kaolinite clays constitute a major component of clay soils.
  • smectites such as nontronite having an ionexchange capacity of approximately 50 meq/100 g. saponite, which has an ion exchange capacity greater than 70 meq/100g., have been found to be useful fabric softeners.
  • the smectite clays commonly used for this purpose herein are all commercially available.
  • Such clays include, for example, montmorillonite, volchonskoite, nontronite, hectorite, saponite, sauconite, and vermiculite.

  • the hectorite clays suitable in the present composition should preferably be sodium clays, for better softening activity.
  • Sodium clays are either naturally occuring, or are naturally-occuring calcium-clays which have been treated so as to convert them to sodium-clays.

Preferably, such a salt is sodium carbonate, typically added at levels of up to 5% of the total amount of clay.
