Definitions

  • Bleach precursors for inclusion in the composition in accordance with the invention typically contain one or more N- or O- acyl groups, which precursors can be selected from a wide range of classes. Suitable classes include anhydrides, esters, imides, nitrites and acylated derivatives of imidazoles and oximes, and examples of useful materials within these classes are disclosed in GB-A-1586789.
  • Suitable materials are those which are normally solid at ⁇ 30°C, particularly the phenyl derivatives, ie. benzoyl valerolactam, benzoyl caprolactam and their substituted benzoyl analogues such as chloro, amino, nitro, alkyl, alkyl, aryl and alkyoxy derivatives.
  • precursor compounds of the benzoxazin-type as disclosed for example in EP-A-332,294 and EP-A-482,807, particularly those having the formula:

  • Preferred sources of hydrogen peroxide include perhydrate bleaches.
  • the perhydrate is typically an inorganic perhydrate bleach, normally in the form of the sodium salt, as the source of alkaline hydrogen peroxide in the wash liquor.
  • This perhydrate is normally incorporated at a level of from 0.1% to 60%, preferably from 3% to 40% by weight, more preferably from 5% to 35% by weight and most preferably from 8% to 30% by weight of the composition.
  • Sodium percarbonate is an addition compound having a formula corresponding to 2Na2C03.3H202, and is available commercially as a crystalline solid. Most commercially available material includes a low level of a heavy metal sequestrant such as EDTA, 1-hydroxyethyIidene 1 , 1- diphosphonic acid (HEDP) or an amino-phosphonate, that is incorporated during the manufacturing process.

  • the percarbonate can be incorporated into detergent compositions without additional protection, but preferred executions of such compositions utilise a coated form of the material.
  • a variety of coatings can be used including borate, boric acid and citrate or sodium silicate of Si02:Na20 ratio from 1.6:1 to 3.4:1 , preferably 2.8:1 , applied as an aqueous solution to give a level of from 2% to 10%, (normally from 3% to 5%) of silicate solids by weight of the percarbonate.
  • the most preferred coating is a mixture of sodium carbonate and sulphate or sodium chloride.
  • the particle size range of the crystalline percarbonate is from 350 micrometers to 1500 micrometers with a mean of approximately 500-1000 micrometers.
  • non-aqueous detergent compositions of this invention may further comprise a surfactant- and low-polarity solvent-containing liquid phase having dispersed therein the bleach precursor composition.
  • a surfactant- and low-polarity solvent-containing liquid phase having dispersed therein the bleach precursor composition.
  • the amount of the surfactant mixture component of the non-aqueous liquid detergent compositions herein can vary depending upon the nature and amount of other composition components and depending upon the desired rheological properties of the ultimately formed composition. Generally, this surfactant mixture will be used in an amount comprising from about 10% to 90% by weight of the composition. More preferably, the surfactant mixture will comprise from about 15% to 50% by weight of the composition.
  • Highly preferred anionic surfactants are the linear alkyl benzene sulfonate (LAS) materials. Such surfactants and their preparation are described for example in U.S. Patents 2,220,099 and 2,477,383, incorporated herein by reference. Especially preferred are the sodium and potassium linear straight chain alkylbenzene sulfonates in which the average number of carbon atoms in the alkyl group is from about 11 to 14. Sodium C-

  • Suitable starting materials would include natural fatty substances as derived from tallow, palm oil, etc.
  • the preferred alkyl ester sulfonate surfactant, especially for laundry applications, comprise alkyl ester sulfonate surfactants of the structural formula:
  • the detergent compositions of the present invention typically comprise from about 1 % to about 40%, preferably from about 5% to about 25% by weight of such anionic surfactants.
  • One class of nonionic surfactants useful in the present invention are condensates of ethylene oxide with a hydrophobic moiety to provide a surfactant having an average hydrophilic-lipophilic balance (HLB) in the range from 8 to 17, preferably from 9.5 to 14, more preferably from 12 to 14.
  • HLB hydrophilic-lipophilic balance
  • the hydrophobic (lipophilic) moiety may be aliphatic or aromatic in nature and the length of the polyoxyethylene group which is condensed with any particular hydrophobic group can be readily adjusted to yield a water-soluble compound having the desired degree of balance between hydrophilic and hydrophobic elements.
  • the alcohol alkoxylate component when utilized as part of the liquid diluent in the non-aqueous compositions herein will generally be present to the extent of from about 1 % to 60% by weight of the composition. More preferably, the alcohol alkoxylate component will comprise about 5% to 40% by weight of the compositions herein. Most preferably, the alcohol alkoxylate component will comprise from about 10% to 25% by weight of the detergent compositions herein.
  • solvent is used herein to connote the non-surface active carrier or diluent portion of the liquid phase of the composition. While some of the essential and/or optional components of the compositions herein may actually dissolve in the "solvenf'-containing phase, other components will be present as particulate material dispersed within the "solvenf'-containing phase. Thus the term “solvent” is not meant to require that the solvent material be capable of actually dissolving all of the detergent composition components added thereto.
  • ancillary anionic surfactants such as alkyl sulfates will generally comprise from about 1% to 10% by weight of the composition, more preferably from about 1 % to 5% by weight of the composition.
  • Alkyl sulfate used as all or part of the particulate material is prepared and added to the compositions herein separately from the unalkoxylated alkyl sulfate material which may form part of the alkyl ether sulfate surfactant component essentially utilized as part of the liquid phase herein.

  • these include alkali metal soaps such as the sodium, potassium, ammonium, and alkylolammonium salts of higher fatty acids containing from about 8 to about 24 carbon atoms, and preferably from about 12 to about 18 carbon atoms.
  • Soaps can be made by direct saponification of fats and oils or by the neutralization of free fatty acids.
  • Particularly useful are the sodium and potassium salts of the mixtures of fatty acids derived from coconut oil and tallow, i.e., sodium or potassium tallow and coconut soap.
  • the particulate-containing liquid detergent compositions of this invention are substantially non-aqueous (or anhydrous) in character. While very small amounts of water may be incorporated into such compositions as an impurity in the essential or optional components, the amount of water should in no event exceed about 5% by weight of the compositions herein. More preferably, water content of the non-aqueous detergent compositions herein will comprise less than about 1 % by weight.
  • the particles of the highly preferred peroxygen bleaching agent can be added to the composition, again while the mixture is maintained under shear agitation.
  • the “total water” is determined by first extracting a weighed amount of finished product with an anhydrous, polar extraction liquid.
  • the extraction liquid is selected in such a way that interferences from dissolved solids are minimized. In most cases, dry methanol is a preferred extraction liquid.
  • the extraction process reaches an equilibrium within a few hours - this needs to be validated for different formulations - and can be accelerated by sonification (ultrasonic bath). After that time, a sample of the extract is centrifuged or filtered to remove the solids, and a known aliqot then introduced into the (coulometric or volumetric) Karl Fischer titration cell. The value found in this way (mg water / kg product) is referred to as "total water" of the formulation.
  • the solution is then spray dried using a lab scale Niro Atomizer spray drier.
  • the inlet of the spray drier is set at 200°C, and the atomizing air is approximately 4 bar.
  • the process air pressure drop is roughly 30-35 mm water.
  • the solution feed rate is set to get an outlet temperature of 100°C.
  • the powdered material is collected at the base of the spray drier.
