252. COMPOSITIONS,

PATENT OFFICE WASHING COMPOSITION Kurt Jochum, Frankfort-on-the-Main, Hermann Geier, Zittan, and Karl Pauser, Frankfort-onthe-Main, Germany, assignors to General Aniline Works, Inc., New York, N. Y., a corporation of Delaware No Drawing. Application October 4, 1934, Serial No. 746,924. In Germany September 4, 1931 9 Claims.
The present invention relates to washing compositions consisting of mixtures of pyrophosphoric acid and washing agents of the following general formula:
R-X-SO; Me
R. stands for an aliphatic radical with at least 7 carbon atoms,
R1 and R2 stand for aliphatic, aromatic or hydroaromatic radicals,
Me stands for an alkali metal atom or am- When being used for washing white linen goods at a temperature of above 50 C., the new washing compositions have the property of imparting to the goods a soft and good touch. The washing agents of the aforenamed general formula which are stable against the compounds causing the hardness of water have the property of yielding precipitates of calcium and magnesium salts on the textile goods after repeated washing if hard water is used and particularly in the presence of sodium carbonate. These separations deposit in the textile fabric and impart to these goods a hard feel. If salts of pyrophosphoric acid are added to these washing agents, it is surprising that the deposition of calcium carbonate or magnesium carbonate in the textile fabric is prevented, even in the presence of sodium carbonate and in very hard water. The salts of the pyrophosphoric acid together with the salts causing the hardness of water yield precipitates which can readily be washed away so that the goods, even after a repeated washing, have a soft and agreeable handle.
As washing agents of the above-named formula which may be used for washing in hard water, there may, for instance, be cited the following: thgallgali metal salts of oleic acid-methyltauride, of lauric a cid phenyltauride,'of 'stea'rib acid tauride, of palmitic acid-ethyltauride, of butyl-tauride of fatty acids from palmnut oil, of hexadecyl-methyl-taurine and of gctadecyltaurine, of the ether from myricyclic alcohol and 'phenol-sulfonic acid, of the ether of n-dodecylalcohol and hydroxyethane-sulfonic acid, of the sulfuric acid ester of octadecyl-alcohol, of the sulfuric acid esters of a mixture of alcohols called lorol (prepared by a catalytic hydrogenation of coconut oil under a high pressure).
As salts of pyrophosphoric acid there may be used the potassium salt, the sodium salt and the ammonium salt. The Washing composition may also be mixed with other substances which are usually added to washing agents, i. e. bleaching agents. As bleaching agents, there may, for instance, be used perborates, such as sodium perborate, percarbonates, such as sodium percarbonate, persulfates, such as potassium mrsulfate.
The following examples serve to illustrate the invention, but they are not intended to limit it thereto, the parts being by weight:-
As an agent for washing white linen goods there may be used the following mixtures:
(1) parts of the sodium salt of the reaction product of stearic acid chloride and methyltaurine of the following formula:
30 parts of sodium carbonate and 10 parts of sodium pyrophosphate.
(2) 40 parts of the sodium salt of the oleic acid ester of hydroxy-ethane-sulfonic acid of the following formula:
C1'IH33 COO C2H4 SOaNa 40 parts of sodium sulfate and 20 parts of sodium pyrophosphate.
(3) 230 parts of fatty acid chloride from palm nut oil are caused to react in an aqueous solution in the presence of caustic soda solution wherein sodium taurine has been dissolved so that the solution always has a feebly alkaline reaction. After the reaction is complete the reaction product is evaporated. 60 parts of the condensation product thus obtained are ground together with 20 parts of sodium carbonate, 10 parts of sodium perborate and 10 parts of potassium pyrophosphate.
(4) 50 parts of the potassium salt of octadecylsulfuric acid of the following formula:
20 parts of anhydrous sodium carbonate, 15 parts of potassium pyrophosphate.
(5) 50 parts of the sodium salt of hexadecylmethyl-taurine of the following formula:
25 parts of sodium carbonate, 15 parts of sodium perborate and 10 parts of sodium pyrophosphate.
(6) 20 parts of the sodium. salt of the reaction product of oleic acid chloride and methyl taurine of the following formula:
r cnnwco-n-mms olNa and parts of potassium salt of pyrophosphoric acid.
