Definitions

  • the present invention relates to fragranced foam control agents and detergent compositions comprising these fragranced foam control agents.
  • Detergent compositions in powder form are used for washing purposes in machines for washing dishes or for laundering of textiles. These compositions generally contain organic surfactants, builders, for example phosphates, bleaching agents and various organic and inorganic additives.
  • the surfactants usually employed in domestic textile washing powders when agitated in an aqueous medium during a washing cycle, tend to yield copious quantities of foam.
  • presence of excessive amounts of foam during a washing cycle in certain washing machines tends to adversely affect the quality of the washing process.
  • silicone foam control agents especially those based on polydimethylsiloxanes, have been found to be particularly useful foam control agents in a variety of media.
  • the major advantage of silicone antifoam over soaps is their excellent performance at low washing temperatures and their independence on water hardness. Soaps in fact only perform in hard water where they form water-insoluble calcium salts that act as antifoams.
  • silicone foam control agents when incorporated in detergent compositions in powder form, appear to lose their effectiveness after prolonged storage in the detergent compositions.
  • silicone antifoams are highly viscous compounds, which need to be mixed with organic waxes or solvents prior to encapsulation, in order to obtain liquid blends that can be processed. It is well described in the public literature that silicone antifoams loose their activity in powder detergents due to the fact that when sprayed on the detergent, they migrate into the powder where they reduce their particle droplet size to an extent that the silicone oil becomes over-emulsified and is not efficient anymore to break foam.
  • Figure 1 illustrates the effect of migration of silicone antifoam onto granular powder resulting in reduction of the droplet size of the silicone antifoam and over-emulsification of the antifoam compound.
  • European patent specification EP 210721 is directed to a silicone foam control agent which is stable on storage. It provides a particulate foam control agent in finely divided form, for inclusion in a powder detergent composition, the agent comprising one part by weight of silicone antifoam and not less than one part by weight of an organic material characterized in that the organic material is a fatty acid or a fatty alcohol having a carbon chain containing from 12 to 20 carbon atoms, or which is a mixture of two or more of these, said organic material having a melting point in the range 45 to 8O 0 C and being insoluble in water, and in that the foam control agent is produced by a process in which the silicone antifoam and the organic material are contacted in their liquid phase.
  • the ratio of organic material to silicone antifoam is kept at 3:1 or above, to ensure free-flowing characteristics of the agent and ease the distribution of the foam control agent in the detergent powder.
  • the most preferred ratio of organic material to silicone antifoam is stated to be from 3:1 to 4:1. The process requires heating of the mixture above the melting point of the wax and the wax does not contribute any additional benefit to the antifoam.
  • European patent specification EP 210731 provides a particulate foam control agent in finely divided form for inclusion in a detergent composition in powder form, characterized in that the agent is wax-free and comprises a silicone antifoam and organic material having a melting point in the range 50 to 85 0 C and comprising a monoester of glycerol and a fatty acid having a carbon chain containing from 12 to 20 carbon atoms.
  • the ratio of organic material to silicone antifoam is stated to be from 2:1 to 2.5:1. Ratios below 1: 1 are said to possibly give both manufacturing problems and storage stability problems, while ratios above 5: 1 are stated not to contribute any extra benefit.
  • Both specifications EP 210721 and EP 210731 state that carrier particles may be included in the foam control agents, which provide a solid basis on which the silicone antifoam and the organic material may be deposited during manufacture. This allows easy mixing in a powder detergent, bulking up the foam control agent to facilitate the dispersibility in the powder detergent. It is stated that the carrier particles are preferably water-soluble solid powders, although the examples given include zeolites and clay minerals as well as sodium sulphate, sodium carbonate, carboxymethyl cellulose and most preferably sodium tripolyphosphate particles.
  • European patent EP 040091 describes suds-suppressing granules which comprise a substantially spherical or cylindrical core material, and one or more coatings comprising a mixture of silicone oil and hydrophobic particles. It is claimed that such granules are less quickly deactivated than those granules in which irregularly shaped substances, such as granular tripolyphosphate, are used as solid core materials for impregnating with silicone antifoams. Suitable core materials mentioned include sucrose, spherical enzyme-containing prills and substantially cylindrical enzyme-containing marumes and Alcalase T granules.
  • European patent EP 071481 describes a detergent composition comprising an anionic surfactant and a suds -controlling agent characterized in that the suds-controlling agent comprises a core of gelatinized starch having a mixture of silicone oil and hydrophobic silica absorbed thereon.
  • the specification also states that preferably the suds-control agent is coated with a layer of wax, preferably paraffin wax, in order to improve the storage characteristics.
  • producing a gelatinized starch derivative requires extra processing steps and there is a need to be able to use materials, which are more commonly available and are less expensive.
  • European patent EP 0496510 describes a granular antifoam where a molten blend of silicone antifoam and stearic acid, stearyl alcohol or glyceryl monostearate is deposited onto native starch.
  • the disadvantage of this formulation is that the waxes are water insoluble and do not dissolve particularly well in normal wash conditions and therefore do not release sufficient antifoam particularly at the beginning of the washing cycle.
  • a general disadvantage of native starch carriers is their poor flowability as they tend to cake. This is a major problem for the process where these antifoam granules have to be mixed with the powder detergent.
  • native starch has a quite low adsorption rate for liquids compared to zeolites for example, which can cause overgranulation, resulting in granules which are too big and cake. Also, native starch gives a slightly yellowish color to the final antifoam granules, which disturbs the perfectly white look of powder detergents.
  • US patent 6,129,906 describes a spray-dried, granular powder comprising: i) from about 50% to about 99% of a water-soluble carrier, ii) from about 1% to about 50% of a hydrophobic silicone oil dispersed within the carrier, wherein the spray-dried powder has a volume average particle size in the range from about 20 microns to about 500 microns, the powder being prepared by spray-drying an aqueous dispersion of the silicone oil and the water-soluble carrier, characterized in that the silicone oil is present in the dispersion in the form of discrete droplets having a volume average droplet size in the range from about 0.5 microns to about 20 microns and that the ratio of the average spray-dried particle size to the average droplet size is at least about 2.5:1.
  • the powder is dry, free -flowing and processable into a punched tablet or other compressed forms, yet efficiently delivers the silicone oil on subsequent dissolution in water.
  • the spray-drying process allows better protection of the encapsulated antifoam compared to the granulation methods described in prior patents.
  • the silicone antifoam compound still needs to be diluted with solvents like silicone copolymers or other organic solvents in order to allow easy dispersion of the active antifoam compound into the emulsion that is spray-dried.
  • Powder detergents are fragranced by spray-applying liquid fragrances onto the powders in a final step. Because fragrances are volatile materials, the spray-application of such fragrances onto powders wastes a significant amount of the fragrance during this process, through evaporation. Furthermore, a homogeneous distribution of the liquid fragrance onto the powder is difficult to obtain.
  • microencapsulated fragrances in powder detergent compositions by blending the granular microencapsulated fragrance with the powder detergent.
  • US patent 6,194,375 describes granular fragranced particles where perfume is absorbed within organic polymer particles, which have a further polymer at their exterior.
  • the further polymer incorporates free hydroxyl groups and serves to promote deposition of the particles from a wash or rinse liquor.
  • the further polymer may be part of an encapsulating shell, but, more conveniently, it is used as a stabilizer during polymerization of the particles. Highly hydrolyzed polyvinyl alcohol is preferred.
  • the resulting granular fragrances are not water-soluble and deposit as particles onto the laundry during a wash cycle.
  • Spray-drying is the most common encapsulation technique used to stabilize volatile substances such as flavors or fragrances, by encapsulating them in a solid form.
  • Granular microencapsulated fragrances that release the fragrance in contact with water are obtained by spray-drying of an emulsion that contains the emulsified fragrance and a water soluble polymeric matrix.
  • Spray-dried powders are commonly made in the usual spray-drying equipment. Spray-drying is usually effected by means of a rotating disc or of multi-component nozzles. Detailed techniques therefor are described for instance in K. Masters, Spray-Drying Handbook, Longman Scientific and Technical, 1991. A particular example of spray-dried fragrances is disclosed in US patent 4,803,195.
  • the microcapsules are formed of a solid film-forming polymer, for example modified starch or polyvinyl alcohol, and an emulsifying agent.
  • the emulsifying agents are chosen from octenyl succinate-substituted starches, mono- or diglycerides of fatty acids, esters derived from fatty acids and sorbitol or a saccharine, or their alkoxylated derivatives, or an ester of tartaric, citric, ascorbic or lactic acid.
  • European patent EP 1348423 describes that fragrances can be encapsulated with only polyvinyl alcohol as the polymeric matrix and without the addition of further emulsifiers, due to the emulsifying properties of polyvinyl alcohol.
  • the matrix consists of a combination of modified starch and polyvinyl alcohol and protects the antifoam upon storage in a powder detergent.
  • the same matrix permits the fragrance to diffuse out off the microcapsules and therefore allows the encapsulated fragrance to contribute to the odor of the dry powder detergent.
  • the fragrance is used as a solvent for the viscous antifoam compound and allows emulsification into the polymeric matrix without addition of further organic solvents and without heating.
  • the antifoam performs as a low volatile diluent for the encapsulated fragrance so that the resulting powder has very low explosivity characteristics.
  • the antifoam is beneficial in retaining more fragrance on the dry fabrics after the wash treatment.
  • the encapsulated fragranced antifoam is therefore beneficial to the final performance of the powder detergent.
  • the granules, containing two important actives of a powder detergent can be obtained in one process step with no further coating step required.
  • the two active ingredients can now be added through one type of granule in one step.
