Definitions

  • the present invention relates to granular detergent compositions having fabric softening properties. Certain amines in intimate mixture with a dispersing aid in the compositions provide through-the-wash softness and anti-static benefits. Detergent compositions in spray-dried form containing said amines are disclosed. the compositions also contain a clay softener
  • Formulators of fabric laundering compositions have long sought means whereby the fabric washing and softening could be done concurrently.
  • Methods employing clay softeners, amine complexes or mixtures of clay and various amine materials, and the like, are described in the following patents : German 29 64 114, 28 57 163, 24 39 541, 23 34 899 and EP 0 023 367, 0 026 528 and 0 028 432, and in EP-A-123400, EP-A-7135 and EP-A-133804.
  • the present invention employs a certain class of amines, intimately mixed with a dispersing aid, in an otherwise conventional detergent composition matrix, and clay, to provide cleaning and, concurrently, softening.
  • compositions herein may be described succinctly as granular detergent compositions which contain conventional detergent ingredients such as detersive surfactants (including anionics), detergency builders and optionally optical brighteners, detersive enzymes, fabric bleaches, and the like, all at conventional levels, which contain clay fabric softeners (preferably, smectite clays), which further contain at least 0.1 % (preferably 1.0 % to 20 %) of an amine having an isoelectric point of at least 9.5, preferably those of the formula R1R2R3N, wherein R1 is C9 to C20 hydrocarbyl and R2 and R3 are each C1 to C4 hydrocarbyl, C2 to C10 alkoxylated hydrocarbyl or hydrogen, the amine being in intimate mixture with a dispersing aid, wherein said dispersing aid is a polycarboxylin acid or an inorganic acid.
  • the amine/acid mixture is sprayed onto the granular detergent matrix.
  • compositions of this invention comprise, in major part, conventional ingredients that are quite familiar to formulators of granular detergent compositions.
  • the amines used herein are entirely compatible with such conventional detergent ingredients, even anionic surfactants.
  • the amines suitable for the compositions herein are selected so that they have an isoelectric point in excess of 9.5, preferably in excess of 10.0.
  • Examples are amines having general formula R1R2R3N, wherein R1 is C8 to C20 hydrocarbyl, preferably C8 to C20 alkyl, more preferably C10 to C14 alkyl, and most preferably C12 alkyl or a mixture of C12 and C14 alkyl.
  • R2 and R3 are each, independently, C1 to C10, hydrocarbyl, or hydrogen.
  • suitable hydrocarbyl radicals are C1 to C4 alkyl or hydroxyalkyl, and C2 to C10 alkoxylated alkyl, in particular ethoxylated alkyl radicals.
  • the amines Prior to incorporation into the detergent matrix, the amines are intimately mixed with a dispersing aid.
  • This class of compounds consists of polycarboxylic acids and inorganic acids, like HF, HCl, HBr, H2SO4, HNO3, HNaSO4, H2SO3, HNaSO3.
  • Bronstedt acids act as dispersing aids
  • the acids protonate a portion of the amine.
  • the protonated amine acts as a dispersing aid for the remaining unprotonated amine.
  • This mechanism suggests that protonated amines per se could be used as dispersing aids, instead, or in combination with the Bronstedt acids.
  • the criticality of the high isoelectric point of the amines (at least 9.5, preferably 10.0 or higher) suggest that it is important that, if protonation indeed takes place, the amines remain protonated during the wash cycle of a laundry program.
  • the amine/dispersing aid mixtures which are key to this invention are prepared separately from the balance of the composition and then the sprayed onto the granular detergent matrix. If the dispersing aid is a Bronstedt acid, this can most conveniently be done by preparing a melt (preferably 1:1 mole ratio) of the acid and the amine and maintaining under continuous mixing the melt stage for about ten minutes whereby the complex forms.
  • the molar ratio amine : acid preferably is about 1:1, but good fabric softening results can also be obtained by mixing the amine with a sub-stoichiometric amount of acid.
  • the acid : amines ratio should be at least 1:10, preferably at least 1:5.
  • the amine/dispersing aid mixtures are used herein at levels of at least 0.1 %, typically at levels of 0.5 % to 20 %, most preferably from 1 % to 10 % of the detergent compositions.
  • the protonated amine is used in combination with a detergent-compatible clay softener.
  • clay softeners are well known in the detergency patent literature and are in broad commercial use, both in Europe and in the United States. Included among such clay softeners are various heat-treated kaolines and various multi-layer smectites.
  • Preferred clay softeners are smectite softener clays that are described in German patent document 2 334 899 and in U.K. patent 1 400 898, which can be referred to for details.
  • Softener clays are used in the preferred compositions at levels of at least 1 %, generally 1-20 %, preferably 2-7 %.
  • compositions of this invention will contain organic surface-active agents ("surfactants") to provide the usual cleaning benefits associated with the use of such materials.
  • surfactants organic surface-active agents
  • Detersive surfactants useful herein include well known synthetic anionic, nonionic, amphoteric and zwitterionic surfactants. Typical of these are the alkylbenzene sulfonates, alkyl- and alkylether sulfates, paraffin sulfonates, olefin sulfonates, alkoxylated (especially ethoxylated) alcohols and alkyl phenols, amine oxides, ⁇ - sulfonates of fatty acids and of fatty acid esters, and the like, which are well known from the detergency art.
  • detersive surfactants contain an alkyl group in the C9-C18 range; the anionic detersive surfactants can be used in the form of their sodium, potassium or tri-ethanolammonium salts; the nonionics generally contain from 5 to 17 ethylene oxide groups.
  • U.S. Patent 4.111.855 contains detailed listings of such typical detersive surfactants. C11-C16 alkyl benzene sulfonates, C12-C18 paraffin sulfonates and alkyl sulfates, and the ethoxylated alcohols and alkyl phenols are especially preferred in the compositions of the present type.
  • surfactant are the water-soluble soaps, e.g. the common sodium and potassium coconut or tallow soaps well known in the art.
  • the surfactant component can comprise as little as 1 % of the compositions herein, but preferably the compositions will contain 5 % to 40 %, preferably 10 % to 30 %, of surfactant. Mixtures of the ethoxylated nonionics with anionics such as the alkyl benzene sulfonates, alkyl sulfates and paraffin sulfonates are preferred for through-the-wash cleansing of a broad spectrum of soils and stains from fabrics.
  • compositions herein can contain other ingredients which aid in their cleaning performance.
  • the present detergent compositions contain a detergent builder and/or metal ion sequestrant.
  • Compounds classifiable and well known in the art as detergent builders include the nitrilotriacetates, polycarboxylates, citrates, water-soluble phosphates such as tri-polyphosphate and sodium ortho- and pyro-phosphates, silicates, and mixtures thereof.
  • Metal ion sequestrants include all of the above, plus materials like ethylenediaminetetraacetate, the amino-polyphosphonates (DEQUEST) and a wide variety of other poly-functional organic acids and salts too numerous to mention in detail here.
  • the builder/sequestrant will comprise 0.5 % to 45 % of the composition.
  • the 1-10 ⁇ m size zeolite (e.g. zeolite A) builders disclosed in German patent 2.422.655 are especially preferred for use in low phosphate compositions.
  • the laundry compositions herein also preferably contain enzymes to enhance their through-the-wash cleaning performance on a variety of soils and stains.
  • Amylase, protease and lipase enzymes suitable for use in detergents are well known in the art and in commercially available liquid and granular detergents.
  • Commercial detersive enzymes preferably a mixture of amylase and protease are typically used at levels of 0.001 % to 2 %, and higher, in the present compositions.
  • compositions herein can contain, in addition to ingredients already mentioned, various other optional ingredients typically used in commercial products to provide aesthetic or additional product performance benefits.
  • Typical ingredients include pH regulants, perfumes. dyes, bleach, optical brighteners, soil suspending agents, hydrotropes and gel-control agents, freeze-thaw stabilizers, bactericides, preservatives, suds control agents, bleach activators and the like.
  • compositions are typically used at a concentration of at least 500 ppm, preferably 0.10 % to 1.5 %, in an aqueous laundry bath at pH 7-11, preferably at pH 9-11, to launder fabrics.
  • the laundering can be carried out over the range from 5°C to the boil, with excellent results.
  • Citric acid is dissolved in methanol (at ca. 30°C). After the addition of the amine, the mixture is stirred for about 15 minutes. Then the methanol is evaporated (e.g. by heating) and the solid residue (mixture of citric acid/dimethyl myristyl amine) is subsequently dried and ground to the desired particle size.
  • This method for preparing the mixture of amine/dispersing aid is suitable when the melting point of the dispersing aid is too high.
