Definitions

  • This invention relates to a novel class of organic sulfur containing detergent compounds. More especially this invention relates to unsymmetrical sulfoximine compounds which are valuable detergent surfactants and to detergency compositions containing such compounds.
  • an active detergent material is compatable with the many adjuvants and additives that are frequently incorporated into detergent formulations, including bleaches and other oxidizing media.
  • novel sulfoximine compounds of this invention have been discovered to be thermally stable and resistant to hydrolysis in basic solutions. Furthermore, sulfoximine compounds of this invention are resistant to further oxidation, unlike the somewhat related sulfoxide detergents which show a propensity to undergo further oxi- Thus unlike the sulfoxides, the novel sulfoximine compounds of this invention can be used advantageously in detergent formulations containing peroxygen bleaches, or in other oxidizing media.
  • Bleaching agents for example those of the peroxygen type, are often used in connection with detergents in the Occasionally in household situations a consumer will add a bleaching agent to a washing solution to aid in the cleaning process. This can easily result in the unintentional inactivation of the detergent compound unless the detergent compound is resistant to such bleaching agents. It is clearly an advantage therefore to have a detergent active that can be used along with such bleaching agents without themselves being transformed into an inactive form.
  • novel sulfoximine compounds of this invention have the following formula:
  • R is an aliphatic radical selected from the group consisting of straight chain, branched chain, saturated and unsaturated alkyl and alkenyl radicals having from 10 to about 18 carbon atoms, and wherein R is an alkyl radical selected from the group consisting of methyl and ethyl radicals.
  • the long chain aliphatic substituent as defined above can be a straight chain, branched chain, saturated or unsaturated aliphatic radical having from 10 to about 18 carbon atoms. Examples are given hereinafter.
  • the long chain aliphatic substituent can suitably be obtained from synthetic or natural sources such as coconut oil fatty alcohol which contains a mixture of alkyl and alkenyl radicals having predominantly a carbon chain length within the prescribed range.
  • Examples of sulfoximine detergent compounds provided -by this invention include the following: decyl methyl sulfoximine, dodecyl methyl sulfoximine, tetradecyl methyl sulfoximine, octadecyl methyl sulfoximine, decyl ethyl sulfoximine, dodecyl ethyl sulfoximine, tetradecyl ethyl sulfoximine, hexadeeyl ethyl sulfoximine, octadecyl ethyl sulfoximine, 2-methyl undecyl methyl sulfoximine, tetrapropylene methyl sulfoximine, dodecenyl methyl sulfoximine and tetradecenyl ethyl sulfoximine.
  • Short chain sulfoximine compounds are known in the prior art. It has never been recognized heretofore, however, that the particular unsymmetrical sulfoximine compounds of this invention have the highly desirable properties for use as detergents in the manner previously set forth.
  • the sulfoximine compounds which have the necessary properties to be good detergent compounds are those which can be termed unsymmetrical sulfoximines.
  • unsymmetrical is meant those sulfoximines in which one aliphatic group is quite long with respect to the other.
  • the short alkyl group should contain no more than two carbon atoms, while the long alkyl chain should contain ten or more carbon atoms. If less than ten carbons are present in the long chain aliphatic hydrocarbon radical, cleaning effectiveness of the compound is seriously impaired.
  • the higher aliphatic radical must contain more than ten carbon atoms, e.g. to 10 to 18 or 20 carbon atoms.
  • the most preferred unsymmetrical sulfoximine compounds are the C -C alkyl methyl sulfoximines. Particularly desirable are the C -C alkyl methyl sulfoximine compounds.
  • the filter cake methyldodecylsulfoximinium sulfate, weighed about 21 g. (71% yield). It was purified by recrystallization from acetone-ethanol or chloroformhexane, to M.P. 128-30.
  • homologous members of the novel class of compounds can be prepared.
  • decyl methyl sulfoxide was used, and essentially the same procedure followed, decyl methyl sulfoximine was recovered in a yield of 25.5%.
  • the compound had a melting point of 51 C.
  • Tetradecyl methyl sulfoximine was prepared according to the previous example by using tetradecyl methyl sulfoxide as a starting material. The compound yield was 61% and the compound had a melting point of 60 C.
  • the dodecyl, decyl and tetradecyl methyl sulfoximines prepared in the manner described above can be used in detergent compositions as hereinafter described.
  • Granular detergent compositions preferably contain about 5% to about 50% of the sulfoximine compounds of this invention and liquid formulations preferably contain about 2% to about of such sulfoximines.
  • Granular detergent compositions preferably contain at least an equal amount of an alkaline builder salt.
  • Liquid formulations preferably contain from about 5% to about of a water soluble alkaline builder salt, the balance of the composition being a solvent such as water, and/ or other liquid vehicles.
  • Water-soluble inorganic alkaline builder salts which can be used alone with the detergent compound or in admixture with other builders are alkali metal carbonates, borates, phosphates, polyphosphates, bicarbonates and silicates. (Ammonium or substituted ammonium salts can also be used.) Specific examples of such salts are sodium tripolyphosphate, sodium carbonate, sodium tetraborate, sodium pyrophosphate, potassium pyrophosphate, sodium bicarbonate, potassium tripolyphosphate, sodium hexametahosphate, sodium sesquicarbonate, sodium monoand di-ortho phosphate and potassium bicarbonate. Potassium pyrophosphate finds wide application especially in built liquid detergent compositions.
  • organic alkaline sequestrant builder salts which can be used alone with the detergent or in admixture with other organic and inorganic builders are alkali metal, ammonium or substituted ammonium, aminopolycarboxylates, e.g. sodium and potassium ethylenediaminetetraacetate, sodium and potassium N-(2-hydroxyethyl)- ethylenediaminetriacetates, sodium and potassium nitrilotriacetates and sodium, potassium and triethanolammonium N-(Z-hydroxyethyl)-nitrilo diacetates. Mixed salts of these polycarboxylates are also suitable.
  • the alkali metal salts of phytic acid, e.g. sodium phytate are also suitable as organic alkaline sequestrant builder salts (see US. Patent 2,739,942).
  • the unsymmetrical sulfoximine detergent compounds may be used as the sole detergent agent or they may be mixed with other well known detergent compounds such as anionic and nonionic detergent compounds.
  • water-soluble salts the sodium, potassium, ammonium, and alkylolammonium salts, for example.
  • Specific examples are: sodium lauryl sulfate; potassium N-methyl lauroyl tauride; triethanolammonium dodecylbenzene sulfonate.
  • nonionic organic detergents which can be used in the compositions of this invention if desired are: polyethylene oxide condensates of alkyl phenols wherein the alkyl group contains from 6 to 12 carbon atoms (e.g. t-octylphenol and the ethylene oxide is present in a molar ratio of ethylene oxide to alkyl phenol in the range of 10:1 to 25:1; condensation products of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylene diamine wherein the molecular weight of the condensation products ranges from 5,000 to 11,000; the condensation products of from 5 to 30 moles of ethylene oxide with one mole of a straight or branched chain aliphatic alcohol containing from 8 to 18 carbon atoms (e.g. lauryl alcohol); C -C alkyl di-(C C alkyl) amine oxides (e.g. dodecyl dimethyl amine oxide).
  • Preferred liquid detergent compositions contain about 2 to about 30% of the sulfoximine compounds of the invention and about 5% to about 40% potassium pyrophosphate.
  • the G -C alkyl methyl sulfoximines are used in such preferred compositions.
  • Particularly desirable in built liquid compositions is dodecyl methyl sulfoximine.
  • the detergent compositions of this invention can contain any of the usual adjuvants, diluents and additives, for example, ampholytic, cationic or zwitterionic detergents, perfumes, anti-tarnishing agents, anti-redeposition agents, bacteriostatic agents, dyes, fiuorescers, suds builders, suds depressors and the like, without detracting from the advantageous properties of the composition.
  • adjuvants for example, ampholytic, cationic or zwitterionic detergents, perfumes, anti-tarnishing agents, anti-redeposition agents, bacteriostatic agents, dyes, fiuorescers, suds builders, suds depressors and the like, without detracting from the advantageous properties of the composition.
  • the above-described sulfoximine compounds are efficient solubilizers and dispersers of calcium soap as well as being hydrolytically stable in base solution and resistant to oxidation from peroxygen type bleaches.
