Definitions

  • Novel detergent and cleansing agents are disclosed characterized by their ability to inhibit the graying of textile articles which takes place in laundering.
  • novel detergent and cleaning agents are effective to prevent the graying of textile articles prepared at least in part with synthetic fibers.
  • the detergent and cleaning agents of the invention are characterized by a content of 0.1 to 20 wt. percent referred to the total composition of at least one water solub le salt of a polyester, the acid radicals of which are derived from a dicarboxylic acid and the alcohol component of which is derived from a dialkanolamine or an 'N-substituted derivative thereof and which has been made water-soluble by the introduction of sulfonic acid or alkylsulfonic acid groups into the molecule.
  • the detergent and cleaning agents contain the conventional surface active materials and the usual additives such as optical brighteners, bleaching agents, sudsers, anti-foamers, etc.
  • This invention relates to detergent and cleaning agents characterized by their ability to inhibit the graying of textile articles in laundering.
  • this invention relates to detergent and cleaning agents containing water-soluble salts or polyesters the acid component of which is derived from a dicarboxylic acid and the alcohol component of which is derived from a dialkanolamine or an N-substituted derivative thereof and which has been made water soluble by the introduction of sulfonic acid or alkylsulfonic acid groups into the molecule.
  • graying inhibitors prevent a resorption of the dissolved dirt onto the cleaned surfaces.
  • These substances are usually polyanionic polymers which are manufactured from natural substances such as cellulose, gelatins or glue, or are prepared by the polymerization of vinyl compounds, such as acrylic acid, methacrylic acid, maleic acid and mixtures thereof with copolymerizable olefins. Further, the polysulfonates of vinyl polymers have already been proposed as useful gray'inhibiting additives for detergent and cleanser preparations.
  • carboxymethylcellulose has achieved any great technical importance, inasmuch as its gray-inhibiting action excels that of any synthetic polymers that have become known.
  • carboxymethylcellulose as well as the above-named synthetic polymers have the disadvantage that their gray-inhibiting action is limited to cellulose fibers, whereas they are practically inetfectual in the washing of synthetic fiber material, particularly materials prepared from polyamides, polyesters and polyolefins. This disadvantage is particularly noticeable in connection with white textiles made of synthetic fibers or mixed fabrics made of synthetic and cellulose fibers, i.e., polyester-cotton mixture, which turn irreversibly gray in use despite repeated washing and thus become unattractive and must be discarded.
  • Another object is to provide improved detergent compositions containing as the gray inhibiting agent, a watersoluble salt of a polyester the acid component of which is derived from a dicarboxylic acid and the alcohol component'of which is derived from a dialkanolamine or an N-substituted derivative thereof and which has been made water soluble by the introduction of sulfonic acid or alkylsulfonic acid groups into the molecule.
  • a yet further object is to provide improved gray inhibiting detergent compositions which are surprisingly etfective in laundering textile articles prapared at least in part with synthetic fibers.
  • detergent compositions comprising a detergent surfactant compound and as a graying inhibitor 0.1 to 20 wt. percent referred to the total detergent compositions of at least one water-soluble salt of a polyester the acid component of which is derived from a dicarboxylic acid and the alcohol component of which is derived from a dialkanolamine or an N-substituted derivative thereof, and which has been made watersoluble by the introduction of sulfonic acid or alkylsulfonic acid groups into the molecule.
  • the polyester salts incorporated into the new detergent compositions in accordance with the invention are manufactured by methods already known in the art.
  • the starting materials for preparing the polyester salts can be aliphatic, cycloaliphatic or aromatic saturated or unsaturated dicarboxylic acids which canzontain 3 (malonic) and up to 20 carbon atoms.
  • particularly suitable acids include malonic, succinic, glutaric, adipic, sebacic, maleic and fumaric acids, benzenedicarboxylic acids and their mixtures.
  • the dialkanolamines which are suitable for use in the reaction to form the polyesters are derived from alcohols having 1 to 6, preferably 2 to 3 carbon atoms, and may be straight-chained or.
  • substituted alkanolamines are N-methyldiethanolamine, N-methyldipropanolamine, N- ethyldiethanolamine, N-propyldipropanolamine, N-propylenediethanolamine, N-butyldiethanolamine, N-dodecyldiethanolamine, N-oleyldiethanolamine, N-cyclohexyldipropanolamine and N-phenyldiethanolamine.
  • the esterification of the reaction components is carried out in a known manner as for example, by heating the dicarboxylic acid and dialkanolamine for several hours under normal pressure in vacuo or in the presence of a solvent with which the water of reaction can be removed azeotropically by distillation.
  • the reaction can be accelerated.
  • their reactive derivatives such as their anhydrides and halides can be used as starting materials.
  • the dicarboxylic acids in the form of their dimethyl or diethyl esters can be re-esterified in the known manner with the al-kanolamines in the presence of conventional re-esterification catalysts.
  • Unsaturated polyesters such as those obtained by reaction of maleic acid and a dialkanolamine, or those in which the hydrocarbon radical on the nitrogen atom is unsaturated, can be converted into the corresponding sulfonates by adding alkalibisulfites onto the double bond. It is also possible to effect the sulfonation of the double bond with complex compounds of sulfur trioxide and an organic compound such as pyridine-, dioxane or N,N- dimethylaniline. In like manner, saturated polyesters can be sulfonated, in which the acid radical, such as the malonic acid radical, contains a reactive methylene group.
  • the unsaturated or saturated polyesters can be reacted with quaternizing agents containing 2 to 6 carbon atoms and a sulfonic acid or sultone group.
  • quarternizing agents are halogen alkylsulfonic acids or their salts, such as, l-bromopropane-3-sulfonic acid and l-chloroethane-Z-sulfonic acid or their alkali salts, and the alkanesultones such as propanesultone or butanesultone.
  • Polymeric sulfobetaines or salts of N- alkylsulfonic acids form in this reaction.
  • the sulfobetaines can be incorporated into the detergent and cleaning compositions as they are or after neutralizing the sulfonic acid group.
  • the ratio of sulfonating or quaternizing agent to polyester is preferably so selected that, after the reaction is ended, there are from -1 to 2 sulfonic acid groups for every two dicarboxylic acid groups or two dialkanolamine groups.
  • polyesters containing sulfonic acid groups and manufactured in the above-described manner are of a resin-like nature, substantially insoluble in water and in organic solvents, but easily soluble in dilute alkali lyes. They may also contain secondary amounts of esters of low molecular weight and of unreacted starting substances which can be removed by extraction with organic solvents and thereafter recycled for further reaction. As these compounds, however, do not impair the cleaning properties of the agents, such separation is generally unnecessary.
  • the detergents may contain the sulfonic acid polyesters according to the-invention in the form of their watersoluble salts and preferably in the form of their alkali metal and ammonium salts.
  • ammonium salts is intended also to include the salts of the polyesters with organic ammonium bases.
  • the polyesters can be added to the detergents in the form of their free acids, providing alkalinely reacting substances are present in a sufiiciently great excess for the formation of salts.
  • the new detergents and cleansing agents contain the surface active substances customarily used in such agents, such as those of the sulfate or sulfonate type, for example, the primary and secondary alkyl sulfates and the sulfates of ethoxylated or propoxylated fatty alcohols, and alkylbenzenesulfonates, primary and secondary olefin sulfonates, alkyl sulfonates and a-sulfofatty esters.
  • the surface active substances customarily used in such agents such as those of the sulfate or sulfonate type, for example, the primary and secondary alkyl sulfates and the sulfates of ethoxylated or propoxylated fatty alcohols, and alkylbenzenesulfonates, primary and secondary olefin sulfonates, alkyl sulfonates and a-sulfofatty esters.
  • Additional compounds of this class which may be used are the high molecular weight sulfatized partial ethers and partial esters of polyvalent alcohols; the sulfates of ethoxylated or propolylated fatty acid amides and alkylphenols; fatty acid taurides and fatty acid isoethionates and homologues thereof. Also suitable are the alkali soaps of fatty acids as well as the fatty acid condensation products of amino acids or degraded proteins; and ampholytes such as alkylbetaines and alkylsulfobetaines.
  • the agents can furthermore contain non-ionic wash-active substances, such as alkyl and acyl polyglycolethers, co-condensation products of polyethylene glycol and polypropylene glycol, fatty acid sugar esters, aminoxides and fatty acid alkanolamides. Any of the foregoing compounds can also be used in the form of maxiures thereof. If the compounds have an aliphatic hydrocarbon radical, the latter is preferably to be straight-chained and have 8 to 22 carbon atoms. In compounds having araliphatic hydrocarbon radicals, the preferably unbranched alkyl chains contain an average of 6 to 16 carbon atoms.
  • the new detergents and cleansers can contain other conventional components such as pyrophosphates, polyphosphates and the more highly condensed phosphates, as well as silicates, in the form of their alkali salts; oxygen-yielding bleaches or bleaches containing active chlorine, such as alkali perborates, alkali percarbonates, alkali hypochlorites, chlorinated cyanuric acids and their alkali salts; as well as neutral salts such as magnesium silicate and sodium sulfate.

  • optical bn'ghteners such as the derivatives of diaminostilbenedisulfonic acid or of diarylpyrazolinesulfonic acid.
  • the detergents may contain suds improvers, such as fatty acid amides, or anti-foaming agents, particularly trialkylmelamines.
  • the new detergents and cleansers may be in solid form, and preferably powder form, or in the form of solutions or pastes. Because of the excellent water solubility of the polyester salts they are particularly well suited for the manufacture of liquid detergent concentrates.
  • Such liquid preparations may contain, in addition, to the abovenamed components, hydrotropic substances such as alkylbenzenesulfonates of low molecular weight, urea, and organic solvents.
  • the cleansing action can be further improved by the addition of standard graying inhibitors, particularly carboxymethylcellulose.

The polyester which was formed thereafter was reacted in the fused state at 150 to 160 C. with 130 g. (1.06 mole) of propanesultone. A portion of the reaction product was dissolved in water with the addition of the equivalent amount of soda lye and adjusted to a content of 10 g. of ester salt per liter.

(1 mole) of N- propyldiethanolamine and 250 g. of xylene were heated together with 1 g. of p-toluenesulfonic acid in a distillation apparatus that had been provided with an apparatus for separating the water and feeding back the solvent. The heating was continued until no more water separated in the receiver. The xylene was decanted from the insoluble resin that was developed, and the residue was freed in vacuo of any remaining solvent. The residue was then boiled with a 10% aqueous solution of sodium bisulfite (total g. Na S O corresponding to 2 moles) until it had completely gone into solution.
