Abstract
Abstract A liquid detergent composition containing as active ingredients anionic surfactants or non-ionic surfactants and at least two kinds of solubilizing agents. The composition contains as one solubilizing agent 3 to 30%, based on the surfactant, of an aliphatic saturated hydrocarbon having 6 to 14 carbon atoms on the average or an alkyl benzene containing an alkyl group having 6 to 14 carbon atoms on the average.

A LIQUID DETERGENT COMPOSITION HAVING IMPROVED LOW TEMPERATURE STABILITY, CONSISTING ESSENTIALLY OF AN AQUEOUS SOLUTION OF AT LEAST ONE SURFACTANTS AND NON-IONIC SURFACTANTS, T CONSISTING OF ANIONIC SURFACTANTS AND NON-IONIC SURFACTANTS, THE AMOUNT OF SAID SURFACTNAT BEING AN AMOUNT EFFECTIVE FOR MAKING SAID DETERGENT COMPOSITION SUITABLE FOR WASHING FOODSTUFFS, TABLEWARE OR CLOTHES, OR AS A SHAMPOO; A FIRST SOLUBILIZING AGENT SELECTED FROM THE GROUP CONSISTING OF ALKANOLS HAVING ONE TO 3 CARBON ATOMS; BENZENE SULFINATES, P-TOLUENE SOLFONATES, XYLENE SULFONATES, ACETYL BENZENE SULFONATES, GLYCOLS, ACETAMIDES, PYRIDINE DICARBOXYLIC ACID AMIDES, BENZOATES, SALICYLATESL AND UREA; AND A SECOND SOLUBILIZING AGENT SELECTED FROM THE GROUP CONSISTING OF HEXYL BENZENE, OCTYL BENZENE, NONYL BENZENE, DODECYL BENZENE AND TETRADECYL BENZENE, SAID LIQUID DETERGENT COMPOSITION CONTAINING FROM ABOUT 3 TO ABOUT 30 PERCENT BY WEIGHT, BASED ON THE WEIGHT BASED ON THE WEIGHT OF SAID SECOND SOLUBILIZING AGENT, THE WEIGHT RATIO OF SAID SECOND SOLUBILIZING AGENT TO SAID FIRST SOLUBILIZING AGENT BEING FROM 1/40 TO 2/1, WHEREBY TO IMPROVE THE LOW TEMPERATURE STABILITY OF THE LIQUID DETERGENT COMPOSITION.
Claim 3
Dependent Claim
111 words
A liquid detergent composition according to claim 1 in which said anionic surfactant is selected from the group consisting of straight or branched alkyl benzene sulfonates, alkyl sulfuric acid ester salts, alkane sulfonates, Alpha -olefin sulfonates, salts of polyoxyethylene alkyl or alkylphenyl ether sulfuric acid esters, and ether carboxylates expressed by the general formula R-O-(CH2H2O)n-R''-COOM in which R is an alkyl or alkenyl group having 8 to 22 carbon atoms or an alkyl phenyl group containing an alkyl group having 6 to 17 carbon atoms, R'' is an alkylene group having 1 to 4 carbon atoms, M stands for a water-soluble cation, and n is a number from 1 to 30.

Claim 5
Dependent Claim
32 words
A liquid detergent composition according to claim 1, in which the amount of said surfactant is from 20 to 35 percent by weight, based on the total weight of said detergent composition.
