Definitions

  • the invention pertains to the use of a water-soluble phosphorylated cellulose in detergent compositions.
  • the invention now provides a water-soluble phosphorylated cellulose for use in detergent compositions which on dissolution in water causes little if any gelling.
  • the invention consists in that the water-soluble phosphorylated cellulose for the known use mentioned in the opening paragraph is obtained by dissolving cellulose in a phosphoric acid-containing solvent to produce a solution 94-100 wt.% of which is composed of the constituents cellulose, phosphoric acid and/or its anhydrides, and water.
  • phosphoric acid in this application refers to all inorganic acids of phosphorus and their mixtures.
  • Orthophosphoric acid is the acid of pentavalent phosphorus, i.e. H 3 PO 4 . Its anhydrous equivalent, i.e., the anhydride, is phosphorus pentoxide (P 2 O ).
  • phosphorus pentoxide P 2 O
  • a series of acids of pentavalent phosphorus having a water- binding capacity in between those of phosphorus pentoxide and orthophosphoric acid e.g., polyphospho c acid (HeP ⁇ , PPA).
  • phosphoric acid and/or its anhydrides and cellulose and/or reaction products of phosphoric acid and cellulose
  • other substances may be present in the solution when preparing phosphorylated cellulose.
  • the solution can be prepared by mixing constituents classifiable into four groups: cellulose, water, inorganic acids of phosphorus including their anhydrides, and other constituents.
  • the "other constituents” may be substances which benefit the processability of the cellulose solution, solvents other than phosphoric acid, or adjuvants (additives), e.g., to counter cellulose degradation as much as possible, or dyes and the like.
  • Cellulose to which phosphorus is bound is also included among the group of constituents making up 94-100 wt.% of the solution.
  • the percentages by weight of cellulose in the solution listed in this patent specification relate to quantities calculated back on the cellulose. This applies in analogous fashion to the quantities of phosphorus mentioned in this specification.
  • US 3,424,545 discloses the use of phosphorylated cotton in an aqueous detergent for home laundering.
  • the phosphorylated cotton was obtained by impregnating "Indianhead” cotton with a solution containing urea and orthophosphoric acid.
  • the resulting phosphorylated cotton which is insoluble in water, was found to function as an effective water-softening agent when used in a detergent as described above.
  • Phosphorylated cellulose obtained by dissolving cellulose in a phosphoric acid-containing solvent to produce a solution 94-100 wt.% of which is composed of the constituents cellulose, phosphoric acid and/or its anhydrides, and water was found to be effective not only as a co-builder, but also as an anti-greying agent or as anti-redeposition agent and dispersant in detergent compositions.
  • co-builders refers in particular to the polymers which are added to detergents which mostly contain zeolite as a builder. Co-builders serve to inhibit the formation and growth of a deposit, e.g., CaCO 3 , on laundered material. The degree of deposit formation is determined by ashing the woven fabric.
  • Detergents for textiles commonly used in Western Europe generally contain 20 - 35 wt.% of zeolite. When used according to the present invention such detergents will contain at most 10 wt.% of phosphorylated cellulose, preferably 1-5 wt.%, more particularly, 2-4 wt %
  • Phosphorylated cellulose obtained by the method described above was found to be especially suitable for use in non-aqueous, i.e. dry detergent compositions (in the form of powder or tablets) It was found that in well- known detergent compositions which contain zeolite among others, this phosphorylated cellulose is especially effective as a co-builder, with a greater effectiveness than well-known co-builders containing polycarboxylic acids and sodium salts. Furthermore, it was found that in such detergent compositions the phosphorylated cellulose is also effective as anti-greying agent or anti- redeposition agent.
  • this phosphorylated cellulose also possesses the favourable property of said constituent's biodegradability.
  • phosphorylated cellulose corresponding to the present invention, which has a content of cellulose-bound phosphorus in the range of 3 to 10 % P, preferably in the range of 4 to 8% P, and a cellulose DP of less than 1000.
  • the cellulose DP is in the range of 100 to 750.
  • Phosphorylated cellulose used according to the invention was found to be suitable for use in detergents for textile products as well as in dishwashing detergents.
  • phosphorylated cellulose For use in powdered detergents preference is given to phosphorylated cellulose in the powder form.
  • phosphorylated cellulose in the form of granules or short fibres (fibrils and/or fibrids) can be employed to this end.
  • Methods for obtaining phosphorylated cellulose in various forms are described in WO 97 30090. Measuring methods
  • the content of cellulose-bound phosphorus can be measured as described in WO 96/06208.
  • the cellulose product is tabletted after being dried in vacuo for some 15 hours at 50°C.
  • an x-ray fluorescent emission spectrometer e.g., a Philips PW 1400 with chromium tube, line: K ⁇ , 50 kV, 50 mA, GE crystal, angle: 141.025, counting time: 50 s
  • the tablet's x-ray fluorescence intensity of phosphorus is then measured.
  • the measured intensity can be converted in a simple manner known to the skilled person to the phosphorus content of the specimen.
  • a laboratory washing machine, make Linitest, is heated to a temperature of 60°C.
  • a standard hard water solution is prepared by dissolving 1 ,56 g of CaCI 2 » 2H 2 O and 1 ,50 g of Na 2 SO in 2 I of demineralised water. - Concentrated basic washing solutions which contain
  • 1 ,25 g of Na 2 CO 3 , 1 , 15 g of NaHCO 3 , 1 ,80 g of water glass 27/8, 1 ,00 g of LABS acid, 1 ,00 g of Elfapur LT 65 SLN, and 12,00 g of zeolite are prepared by dissolving the constituents in 1 I of demineralised water.
  • 50 ml of the basic washing solution is heated to 40°C and the amount of material to be tested is dissolved in it.
  • the following standard washcloths are employed per test setting:
  • the cup is sealed and placed in the Linitest washing machine. - The Linitest washing machine is kept in operation for 30 minutes.
  • the washcloths are wrung out by hand and spread out on a towel.
  • the EMPA 101 standard washcloths are removed after each washing cycle.
  • the washing step is performed 10x, with use being made of a new
  • the amount of residual ash is determined by pyrolising 2 g (m 0 ) of the EMPA 211 washcloths in a china crucible for 1 hour at 900°C. On conclusion of the test the weight of the remaining ash is determined
  • the ash content (in %) is calculated via mj/m 0 x 100%. Greying is measured as the difference in reflectance between treated and untreated washcloths.
  • the washed dishes were also assessed in accordance with DIN 44990.
