Definitions

  • the present invention relates to detergent compositions, especially liquid, granular and tablet forms of laundry detergent compositions, that comprise improved hydrotropes, wherein the hydrotropes are organic molecules in which two polar groups are separated from each other by at least 5 aliphatic carbon atoms; liquid compositions that contain such hydrotropes have a viscosity, dilution profile and dissolution behavior that render the product effective and convenient for use as a liquid laundry detergent composition.
  • Liquid laundry detergent products offer a number of advantages over dry, powdered or particulate laundry detergent products.
  • Liquid laundry detergent products are readily measurable, speedily dissolved in wash water, non-dusting, are capable of being easily applied in concentrated solutions or dispersions to soiled areas on garments to be laundered and usually occupy less storage space than granular products.
  • liquid laundry detergents may have incorporated into their formulations materials which would deteriorate in the drying operations employed in the manufacture of particulate or granular laundry detergent products. Because liquid laundry detergents are usually considered to be more convenient to use than granular laundry detergents, they have found substantial favor with consumers.
  • detergent compositions in tablet form by compacting a granular detergent composition.
  • Such tablets offer the convenience to consumers of a pre-measured detergent dosage without the inconvenience and untidiness of measuring a sufficient amount of a granular detergent composition for each wash.
  • Such products also offer considerable convenience to those consumers who launder the clothes outside or away from their residence (e.g. at a laundromat) because the consumer is required to transport only precisely as much laundry detergent as she or he needs for clothes laundering.
  • Detergent compositions may be made in tablet form by compacting detergent particulates.
  • Laundry detergent components which may be compatible with each other in granular and/or tablet products, may tend to interact or react with each other in a liquid, especially in an aqueous liquid environment.
  • a disadvantage with conventional granular/powder detergent compositions has been relatively poor dissolution, dispersion and solubility performance.
  • a disadvantage with conventional tablet detergent compositions has been the conflict between making the tablets sufficiently strong and durable to avoid breaking apart during manufacture, transportation and/or storage, while at the same time making the tablets in a manner such that the tablets rapidly disintegrate upon contact with wash water.
  • liquid detergent compositions which have not only excellent cleaning performance and compositional and physical stability but which also have a viscosity, dilution profile and dissolution behavior that render them useful and convenient for use as a liquid laundry detergent composition;
  • the present invention is directed to a laundry detergent composition according to claim 1.
  • liquid detergent products containing these hydrotropes demonstrate excellent cleaning performance, excellent compositional and physical stability and favorable product rheological behavior.
  • These certain hydrotropes may be most generally classified as organic molecules in which two polar groups are separated from each other by at least 5 aliphatic carbon atoms.
  • the liquid detergent products may be aqueous or non-aqueous.
  • a nonaqueous liquid detergent comprising a hydrotrope having two polar groups separated from each other by at least 5 aliphatic carbon atoms as well as from about 49% to about 99.95% by weight of the composition of a surfactant-containing non-aqueous liquid phase and from about 1% to about 50% by weight of the composition of particulate material which is substantially insoluble in said liquid phase and which is selected from peroxygen bleaching agents, bleach activators, organic detergent builders, inorganic alkalinity sources and combinations thereof, is provided.
  • Hydrootrope generally means a compound with the ability to increase the solubilities, preferably aqueous solubilities, of certain slightly soluble organic compounds, more preferably “hydrotrope” is defined as follows (see S.E. Friberg and M. Chiu, J. Dispersion Science and Technology, 9(5&6), pages 443 to 457, (1988-1989 )):
  • Non-Aqueous or “Anhydrous” - As used herein, “non-aqueous” or “anhydrous” are used synonymously and both describe a fluid in which the free water content is less than about 1 %.
  • Polar groups refers to functional groups which have a permanent electric dipole moment that arises from the partial charges on atoms linked by polar bonds.
  • the polar group itself may be anionic or uncharged.
  • Dissolution refers to the rate at which the detergent product mixes with water and releases the active ingredients in the wash
  • particles means the entire size range of a detergent final product or component or the entire size range of discrete particles, agglomerates, or granules in a final detergent product or component admixture. It specifically does not refer to a size fraction (i.e., representing less than 100% of the entire size range) of any of these types of particles unless the size fraction represents 100% of a discrete particle in an admixture of particles.
  • the entire size range of discrete particles of that type have the same or substantially similar composition regardless of whether the particles are in contact with other particles.
  • the agglomerates themselves are considered as discrete particles and each discrete particle may be comprised of a composite of smaller primary particles and binder compositions.
  • Geometric Mean Particle Diameter As used herein, the phrase “geometric mean particle diameter” means the geometric mass median diameter of a set of discrete particles as measured by any standard mass-based particle size measurement technique, preferably by dry sieving.
  • hydrotropes described in this section are an essential component of the present detergent compositions.
  • hydrotrope in which two polar groups are separated from each other by at least 5, preferably 6, aliphatic carbon atoms.
  • suitable polar groups for inclusion in the hydrotrope include are hydroxyl and carboxyl ions.

  • Such a surfactant-containing liquid phase will frequently have a density of from about 0.6 to 1.4 g/cc, more preferably from about 0.9 to 1.3 g/cc.
  • hydrotropes described above prevent the formation of the viscous surfactant phases formed upon dilution, because the hydrotrope can effectively interact with the ordered, structured layers of surfactant molecules, disrupt them and promote the formation of isotropic low - viscosity surfactant phases.
  • hydrotropes also provide other benefits for improving the rheology of liquid detergent compositions.
  • Ethoxylated quaternized amine materials are described in greater detail below.
