Definitions

  • the present invention is concerned with rinse-active foam control particles for inclusion in a detergent composition, i.e. foam control particles mainly active in the rinse-cycle of a laundry process, with a method for making such particles, and with detergent
  • compositions containing such particles are provided.
  • suds-control during the washing cycle of a laundry process is important, so as to avoid negative interference with the action of the wash liquor upon the fabrics, it is also known that suds-control during the rinse cycle of a laundry process is desirable; Indeed, excessive foaming during the rinse cycle in a washing machine can cause foam spillage and damage to the machine, while in a handwash context, there is an advantage in lowering the foam production during rinsing, so as to shorten this step.
  • Soaps of fatty acids have been used for such a rinse-active suds control function, and they have always been spray dried together with the rest of the detergent composition;
  • the present invention provides foam control fatty acid soap particles which are made separately from the rest of the spray-dried detergent composition, and a process to make them, not causing organic emissions.
  • the present invention provides rinse-active foam- control particles for inclusion in a detergent
  • composition in powder form consisting essentially of a soap of fatty acids of which at least 80% contain from 16 to 18 carbon atoms, the geometric mean
  • particle size of the particles being inferior to 1 mm, preferably inferior to 0.4 mm.
  • the present invention also encompasses a process for making said foam-control agents, as well as high suds and low sud executions of detergent compositions containing said foam-control particles.
  • the antifoam particles are the antifoam particles.
  • the foam-control particles of the invention are mainly constituted of a soap of fatty acids of which at least 80% by weight contain from 16 to 18 carbon atoms; preferred fatty acids are tallow or
  • tallow/coconut mixtures at a weight ratio of tallow to coconut not less than 70/30; particularly preferred is a 90/10 tallow/coconut mixture.
  • Suitable cations which render the soap water soluble and/or dispersible include sodium, potassium, ammonium,
  • the particles of the invention are further divided by the particles of the invention.
  • the geometric mean particle size which is the median of the cumulative weight distribution, should be less than 1 mm and preferably less than 0.4 mm.
  • the individual particle size of a particle is meant as being the sum of the longest and the shortest dimension of the particle divided by two.
  • the cumulative weight distribution of the particles can be conveniently measured by sieving with an airfluidized sieve.
  • the particles herein optionally include a free- flowing agent such as amorphous silica, at levels not exceeding 5% by weight of the particle.
  • the process herein contains essentially the steps of drying a fatty acid soap slurry to a low moisture level, i.e. a moisture level not exceeding 9%, preferably not exceeding 5% by weight of the slurry, then pressing the slurry into noodles, and
  • control of the moisture level is a particularly critical feature of the process herein, since
  • Drying of the soap slurry is preferably achieved under vacuum. Supplementary drying during the
  • grinding process may be appropriate, and achieved for example in an air classifier.
  • a typical method to measure the moisture level in the sopa slurry and/or the noodles is a solvent distillation method, using a Bidwell ® apparatus.
  • a detergent composition in powder form comprising a surface-active agent and foam control particles such as described above.
  • Addition of the particles herein in detergent compositions can be achieved by e.g. dry-mixing.
  • the amount of foam control particles is typically from 0.25 to 5% by weight of the composition, depending on the type of detergent composition involved.
  • a wide range of surfactants can be used in the detergent compositions.
  • anionic surfactants are particularly suitable herein, especially mixtures of sulphonate and sulphate surfactants in a weight ratio of from 5:1 to
  • Preferred sulphonates include alkyl benzene sulphonates having from 9 to 15, especially 11 to 13 carbon atoms in the alkyl radical, and alphasulphonated methyl fatty acid esters in which the fatty acid is derived from a C 12 -C 18 fatty source preferably from a C 16 -C 18 fatty source.
  • the cation is an alkali metal, preferably sodium.
  • Preferred sulphate surfactants are alkyl sulphates having from 12 to 18 carbon atoms in the alkyl radical , optionally in admixture with ethoxy sulphates having from 10 to 20, preferably 10 to 16 carbon atoms in the alkyl radical and an average degree of ethoxylation of 1 to 6.
  • alkyl sulphates herein are tallow alkyl sulphate, coconut alkyl sulphate, and C 14 -C 15 alkyl sulphates.
  • the cation in each instance is again an alkali metal cation, preferably sodium.
  • 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 13.5, more preferably from 10 to 12.5.
  • HLB hydrophilic-lipophilic balance
  • (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.
  • Especially preferred nonionic surfactants of this type are the C 9 -C 15 primary alcohol ethoxylates containing 3-8 moles of ethylene oxide per mole of alcohol, particularly the C 14 -C 15 primary alcohols containing 6-8 moles of ethylene oxide per mole of alcohol and the C 12 -C 14 primary alcohols containing 3-5 moles of ethylene oxide per mole o f alcohol.
