Definitions

  • the present invention relates to a high bulk density granular detergent composition having an excellent solubility.
  • Conventional clothing detergents contain extender fillers (usually Glauber's salt or sodium sulfate (10H2O) is used) which contribute almost nothing to the washing performance and are manufactured as bead-like, hollow granules with a bulk density of approximately 0.3 g/cc by spray drying etc. of the same.
  • extender fillers usually Glauber's salt or sodium sulfate (10H2O) is used
  • the objects of the present invention are to eliminate the above-mentioned problems of the prior art and to provide a high bulk density granular detergent composition having an excellent solubility.
  • a high bulk density granular detergent composition comprising:
  • JP-A-62199695 discloses a high density granular detergent composition comprising 25 parts of sodium sulfonate of hardened tallow methyl ester. Tallow, however, has a different composition with respect to the fatty acid esters and does not meet the a/b relationship postulated by the invention.
  • the fatty acid lower alkyl ester sulfonates are typically represented by the following general formula (I). These are also called ⁇ -sulfo-fatty acid ester salts.
  • R1 represents an alkyl group as defined above, R represents an alkyl group having approximately 1 to 3 carbon atoms and M represents a counter ion.
  • a water soluble salt such as an alkali metal salt, particularly a sodium salt, is preferably used.
  • a sulfonate of a saturated fatty acid C1 to C3 alkyl ester may be prepared by obtaining a fatty acid lower alkyl ester having a predetermined number of 1 to 3 carbon atoms by ester exchange or esterification of fatty acid, then using a usual sulfonation apparatus for a reaction with sulfuric anhydride or another sulfonating agent, aging, if necessary, bleaching, then neutralizing. Further, it may be obtained by lower alkyl esterification of sulfonates of fatty acids.
  • an unsaturated fatty acid C1 to C3 alkyl ester sulfonate may be used in the present invention. This is produced in the same manner as mentioned above by using, as a starting material, unsaturated fatty acids and the like having a predetermined number of carbon atoms.
  • fatty acids having a predetermined number of carbon atoms of animal and vegetable sources derived from beef tallow, coconut oil, palm oil, and the like and synthetic fatty acids may be used.
  • the present invention improves the solubility by combined use, in specific ratios, of two components (a) and (b) having the following specific numbers of carbon atoms, in the above-mentioned fatty acid C1 to C3 alkyl ester sulfonates:
  • the above-mentioned two components (a) and (b) are combined in a total weight of 5 to 30% by weight, preferably 8 to 25% by weight, in the detergent composition.
  • the amount combined is less than 5% by weight, sufficient detergent power cannot be obtained, while when it is more than 30% by weight, the commercial production becomes difficult.
  • the high bulk density detergent composition according to the present invention may include, in addition to the essential components of the above-mentioned (a) and (b), other surface active agents, builders, and other desired optional components.
  • anionic surface active agent for example, the following may be mentioned.
  • salts of alkali metal such as sodium, potassium or the like are generally suitable.
  • nonionic surface active agent the following are preferable.
  • zeolite aluminosilicates
  • sodium tripolyphosphate sodium pyrophosphate, and other inorganic builders
  • sodium citrate sodium ethylene diamine tetraacetate, nitro triacetate
  • sodium polyacrylate sodium acrylate-sodium maleic anhydride copolymer
  • polyacetal carboxylate and other calcium ion catching builders
  • carbonates, silicates, and other alkaline builders carboxymethylcellulose, polyethylene glycol and other recontamination preventers
  • soap and other rinsing improvers para-toluene sulfonates, toluene sulfonates, xylene sulfonates, urea and other viscosity adjusters
  • protease, lipase, cellulase, amylase in particular alkaline lipase and the like having activity in alkaline environments
  • other enzymes quaternary ammonium salts, bentonite, and other soften
  • the detergent composition according to the present invention can be obtained by granulating the above-mentioned components to make a high bulk composition having a bulk density of 0.5 to 1.2 g/cc.
  • the method of granulation as disclosed in the above-mentioned Japanese Unexamined Patent Publication (Kokai) No. 62-597, the fatty acid lower alkyl ester sulfonates and other detergent components may be kneaded with a kneader, mixed, milled by a mill of the cutter mill type or the like, granulated, and further mixed with a water-insoluble fine powder.
  • all or part of the detergent components may be spray dried, the remaining detergent compositions kneaded and mixed in with the spray dried components, and thus the desired high bulk density granular detergent composition can be produced.
  • the enzymes and other components they may be blended as powders with the granulated detergent.
  • the dense mixture pellets having a 2 cm square thus obtained and type A zeolite were fed at a constant speed to a mill (manufactured by a Okada Seiko, Speed Mill ND-30).
  • cold air having a temperature of 15°C was introduced at a rate of 15 liters per kilogram of milling material.
  • the mill had 15 cm diameter milling blades rotating at 3000 rpm in four stages crosswise and used punched metal with a 20% holes of 2 mm diameter as the screen.
