Definitions

  • Lamellar phases cause the resultant liquid product to be turbid (i.e. cloudy).
  • a lamellar-structured detergent liquid which is substantially clear (i.e. substantially transparent).
  • Products with a microstructure consisting of predominantly planar lamellar phases are usually less turbid than products with a microstructure of lamellar droplets.
  • these products have usually an inhomogeneous appearance and are not substantially clear, so that visually, they do not have a pleasing appearance.
  • compositions according to the present invention have a physical form which may be that of a liquid, a pourable gel or a non-pourable gel. These forms are conveniently characterised by the product viscosity. In these definitions, and unless indicated explicitly to the contrary, throughout this specification, all stated viscosities are those measured at a shear rate of 21 s -1 and at a temperature of 25°C.
  • compositions according to the present invention which are liquids, preferably have a viscosity of no more than 1,500 mPa.s, more preferably no more than 1,000 mPa.s, still more preferably, no more than 500 mPa.s.
  • the enzyme capsules can also contain hydrophobic or fatty materials. Examples of this are:
  • the enzyme encapsulate may comprise polymeric material.
  • the enzyme encapsulate comprise polymeric materials selected from the group consisting of polyvinylalcohol, polyamide, polyester, polyurea, polyurethane, epoxyresin, methylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, carrageenan, alginate, gellan gum, gelatine and mixtures thereof.
  • the amount of material of deflocculating polymer in a composition according to the invention will be from 0.01% to 5.0% by weight of the composition, most preferably from 0.1% to 2.0%.
  • Suitable soaps include alkali metal soaps of long chain mono- or dicarboxylic acids for example one having from 12 to 18 carbon atoms.
  • Typical acids of this kind are oleic acid, ricinoleic acid and fatty acids derived from castor oil, rapeseed oil, groundnut oil, coconut oil, palm kernel oil or mixtures thereof.
  • the sodium or potassium soaps of these acids can be used.
  • Examples 20-22 different sugars + Silverson (shear rate ca 50,000 sec -1 ). This further illustrates the benefits of shearing and also illustrates the benefit of higher mono- and di-saccharide contents in commercial 'glucose' syrups. It also demonstrates that shearing in the absence of sugar addition (partial refractive index matching) is not sufficient.
  • Ingredient % by weight if not otherwise stated
