Definitions

  • the present invention relates to liquid laundry detergents which contain fragrance, and especially concerns liquid laundry detergents which contain a combination of
  • fragrance at key moments is a difficult task since laundry washing liquids are usually designed to carry oily materials or particulate solids away from the laundered fabric. Fragrances, however, are also typically oily materials.
  • Encapsulation of fragrance allows for improved deposition of fragrance to fabric, as well as delaying the release of fragrance when the consumer garment is being worn.
  • the present invention provides a liquid laundry detergent composition
  • a liquid laundry detergent composition comprising: a) from 3 to 60% (by weight based on the total weight of the composition) of one or more detersive surfactants selected from non-soap anionic surfactants, nonionic surfactants and mixtures thereof; b) from 0.01 to 1% (by weight based on the total weight of the composition) of a fragrance formulation (f1 ) which is in the form of free droplets dispersed in the composition; c) from 0.01 to 1% (by weight based on the total weight of the composition) of a fragrance formulation (f2) which is entrapped within discrete polymeric microparticles dispersed in the composition; in which the total amount of fragrance formulation (f1 ) and fragrance formulation (f2) ranges from 0.6 to 0.9% (by weight based on the total weight of the composition);

  • Naturally occurring exudates such as essential oils extracted from plants may also be used as fragrant components in the invention.
  • Essential oils are usually extracted by processes of steam distillation, solid-phase extraction, cold pressing, solvent extraction, supercritical fluid extraction, hydrodistillation or simultaneous distillation-extraction.
  • Essential oils may be derived from several different parts of the plant, including for example leaves, flowers, roots, buds, twigs, rhizomes, heartwood, bark, resin, seeds and fruits.
  • the major plant families from which essential oils are extracted include Asteraceae, Myrtaceae, Lauraceae, Lamiaceae, Myrtaceae, Rutaceae and Zingiberaceae.
  • the oil is "essential" in the sense that it carries a distinctive scent, or essence, of the plant.
  • Essential oils are understood by those skilled in the art to be complex mixtures which generally consist of several tens or hundreds of constituents. Most of these constiuents possess an isoprenoid skeleton with 10 atoms of carbon (monoterpenes), 15 atoms of carbon (sesquiterpenes) or 20 atoms of carbon (diterpenes). Lesser quantities of other constituents can also be found, such as alcohols, aldehydes, esters and phenols.

  • no single fragrant component will comprise more than 60% by weight of the total weight of fragrance formulation (f1 ) and more preferably no single fragrant component will comprise more than 50% by weight of the total weight of fragrance formulation (f 1 ).
  • the term“fragrance formulation” in the context of this invention denotes the fragrant components as defined above, plus any optional excipients. Excipients may be included within fragrance formulations for various purposes, for example as solvents for insoluble or poorly-soluble components, as diluents for the more potent components or to control the vapour pressure and evaporation characteristics of the fragrance formulation.
  • Excipients may have many of the characteristics of fragrant components but they do not have strong odours in themselves. Accordingly, excipients may be distinguished from fragrant components because they can be added to fragrance formulations in high proportions such as 30% or even 50% by weight of the total weight of the fragrance formulation without significantly changing the odour quality of the fragrance formulation.
  • suitable excipients include ethanol, isopropanol, diethylene glycol monoethyl ether, dipropylene glycol, diethyl phthalate and triethyl citrate. Mixtures of any of the above described materials may also be suitable.

  • the content of fragrant components preferably ranges from 50 to 100%, more preferably from 60 to 100% and most preferably from 75 to 100% by weight based on the total weight of fragrance formulation (f1 ); with one or more excipients (as described above) making up the balance of the fragrance formulation (f1 ) as necessary.
  • Fragrance formulation (f1 ) is in the form of free droplets dispersed in the composition.
  • the term“free droplets” in the context of this invention denotes droplets which are not entrapped within discrete polymeric microparticles.
  • the level of fragrance formulation (f1 ) will generally range from 0.1 to 0.75%, and preferably ranges from 0.3 to 0.6% (by weight based on the total weight of the composition).

  • Fragrance formulation (f2) is entrapped within discrete polymeric microparticles dispersed within the composition.
  • One type of microparticle suitable for use in the invention is a microcapsule.
  • Microencapsulation may be defined as the process of surrounding or enveloping one substance within another substance on a very small scale, yielding capsules ranging from less than one micron to several hundred microns in size.
  • the material that is encapsulated may be called the core, the active ingredient or agent, fill, payload, nucleus, or internal phase.
  • the material encapsulating the core may be referred to as the coating, membrane, shell, or wall material.
  • Microcapsules typically have at least one generally spherical continuous shell surrounding the core.

  • Multiple shells may be made of the same or different encapsulating materials, and may be arranged in strata of varying thicknesses around the core.
  • the microcapsules may be asymmetrically and variably shaped with a quantity of smaller droplets of core material embedded throughout the microcapsule.
  • the shell may have a barrier function protecting the core material from the environment external to the microcapsule, but it may also act as a means of modulating the release of core materials such as fragrance.
  • a shell may be water soluble or water swellable and fragrance release may be actuated in response to exposure of the microcapsules to a moist environment.
  • a microcapsule might release fragrance in response to elevated temperatures.
  • Microcapsules may also release fragrance in response to shear forces applied to the surface of the microcapsules.
  • a preferred type of polymeric microparticle suitable for use in the invention is a polymeric core-shell microcapsule in which at least one generally spherical continuous shell of polymeric material surrounds a core containing the fragrance formulation (f2).
  • the shell will typically comprise at most 20% by weight based on the total weight of the
  • the fragrance formulation (f2) will typically comprise from about 10 to about 60% and preferably from about 20 to about 40% by weight based on the total weight of the microcapsule.
  • the amount of fragrance (f2) may be measured by taking a slurry of the microcapsules, extracting into ethanol and measuring by liquid
  • Polymeric core-shell microcapsules for use in the invention may be prepared using methods known to those skilled in the art such as coacervation, interfacial polymerization, and polycondensation.
  • Coacervation typically involves encapsulation of a generally water- insoluble core material by the precipitation of colloidal material(s) onto the surface of droplets of the material.
  • Coacervation may be simple e.g. using one colloid such as gelatin, or complex where two or possibly more colloids of opposite charge, such as gelatin and gum arabic or gelatin and carboxymethyl cellulose, are used under carefully controlled conditions of pH, temperature and concentration.
  • Interfacial polymerisation typically proceeds with the formation of a fine dispersion of oil droplets (the oil droplets containing the core material) in an aqueous continuous phase.
  • the dispersed droplets form the core of the future microcapsule and the dimensions of the dispersed droplets directly determine the size of the subsequent microcapsules.
  • Microcapsule shell-forming materials are contained in both the dispersed phase (oil droplets) and the aqueous continuous phase and they react together at the phase interface to build a polymeric wall around the oil droplets thereby to encapsulate the droplets and form core-shell microcapsules.
  • An example of a core-shell microcapsule produced by this method is a polyurea microcapsule with a shell formed by reaction of diisocyanates or polyisocyanates with diamines or polyamines.
  • Polycondensation involves forming a dispersion or emulsion of the core material in an aqueous solution of precondensate of polymeric materials under appropriate conditions of agitation to produce capsules of a desired size, and adjusting the reaction conditions to cause condensation of the precondensate by acid catalysis, resulting in the condensate separating from solution and surrounding the dispersed core material to produce a coherent film and the desired microcapsules.
  • An example of a core-shell microcapsule produced by this method is an aminoplast microcapsule with a shell formed from the polycondensation product of melamine (2,4,6-triamino-1 ,3,5-triazine) or urea with formaldehyde.
  • Suitable cross-linking agents e.g. toluene diisocyanate, divinyl benzene, butanediol diacrylate
  • secondary wall polymers may also be used as appropriate, e.g. anhydrides and their derivatives, particularly polymers and co- polymers of maleic anhydride.
  • One example of a preferred polymeric core-shell microcapsule for use in the invention is an aminoplast microcapsule with an aminoplast shell surrounding a core containing the fragrance formulation (f2). More preferably such an aminoplast shell is formed from the polycondensation product of melamine with formaldehyde.

  • the particle size distribution can be narrow, broad or multimodal.
  • the microcapsules as initially produced may be filtered or screened to produce a product of greater size uniformity.
  • Polymeric microparticles suitable for use in the invention may be provided with a deposition aid at the outer surface of the microparticle.
  • Deposition aids serve to modify the properties of the exterior of the microparticle, for example to make the microparticle more substantive to a desired substrate.
  • Desired substrates include cellulosics (including cotton) and polyesters (including those employed in the manufacture of polyester fabrics).
  • the deposition aid may suitably be provided at the outer surface of the microparticle by means of covalent bonding, entanglement or strong adsorption.
  • Examples include polymeric core-shell microcapsules (such as those further described above) in which a deposition aid is attached to the outside of the shell, preferably by means of covalent bonding. While it is preferred that the deposition aid is attached directly to the outside of the shell, it may also be attached via a linking species.
