Abstract
Abstract The detergent composition having a good detergency, a good transparency and the function of imparting a freshness preservation ability to food or the like comprises a sucrose ester component which comprises at least one sucrose ester of fatty acid having six to 22 carbon atoms, an organic acid component which is a member selected from the group consisting of malic acid, tartaric acid, alkaline salts of malic acid or tartaric acid and mixtures of the foregoing and preferably further includes an amino acid component and/or a saccharide component.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
AN AQUEOUS DETERGENT COMPOSITION HAVING A GOOD AND STABLE TRANSPARENCY CONSISTING ESSENTIALLY OF 3 TO 25 PARTS BY WEIGHT OF AT LEAST ONE SUCROSE ESTER OF A SATURATED OR UNSATURATED FATTY ACID HAVING FROM SIX TO 22 CARBON ATOMS, THE DEGREE OF SUBSTITUTION OF SUBSTITUTION OF SAID SUCROSE ESTER GIVEN BY THE AVERAGE VALUE OF THE NUMBER OF ESTERIFIED FATTY ACID MOLECULES PER ONE SUCROSE MOLECULE BEING WITHIN THE RANGE OF 1.0 TO 1.8, 3 TO 45 PARTS BY WEIGHT OF AN ORGANIC ACID COMPONENT WHICH IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF MALIC ACID, ALKALI METAL SALT OF MALIC ACID AND MIXTURES OF THE FOREGOING, AND 30 TO 94 PARTS BY WEIGHT OF WATER.
Claim 2
Dependent Claim
117 words
AN AQUEOUS DETERGENT COMPOSITION HAVING A GOOD AND STABLE TRANSPARENCY CONSISTING ESSENTIALLY OF 3 TO 25 PARTS BY WEIGHT OF AT LEAST ONE SUCROSE ESTER OF A SATURATED OR UNSATURATED FATTY ACID HAVING FROM SIX TO 22 CARBON ATOMS, THE DEGREE OF SUBSTITUTION OF SUBSTITUTION OF SAID SUCROSE ESTER GIVEN BY THE AVERAGE VALUE OF THE NUMBER OF ESTERIFIED FATTY ACID MOLECULES PER ONE SUCROSE MOLECULE BEING WITHIN THE RANGE OF 1.0 TO 1.8, 3 TO 45 PARTS BY WEIGHT OF AN ORGANIC ACID COMPONENT WHICH IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF MALIC ACID, ALKALI METAL SALT OF MALIC ACID AND MIXTURES OF THE FOREGOING, AND 30 TO 94 PARTS BY WEIGHT OF WATER.
Claim 3
Dependent Claim
77 words
An aqueous detergent composition as defined in claim 1, in which said sucrose ester consists essentially of a sucrose ester of a mixed fatty acid, at least 70 percent by weight of said mixed fatty acid being fatty acid having 12 carbon atoms and the degree of substitution of said sucrose ester given by the average value of the number of esterified fatty acid molecules per one sucrose molecule being within the range of 1.23 to 1.57.
Claim 4
Dependent Claim
25 words
An aqueous detergent composition as defined in claim 1, further including a saccharide component which is selected from the group consisting of sucrose and sorbitol.
Claim 5
Dependent Claim
33 words
An aqueous detergent composition as defined in claim 1 in which said saccharide component is included in an amount of 5 to 30 percent by weight of the total amount of said composition.
Claim 6
Dependent Claim
88 words
An aqueous detergent composition having a good and stable transparency consisting essentially of 5 to 20 parts by weight of a sucrose ester of a saturated or unsaturated fatty acid having from six to 22 carbon atoms, the degree of substitution of said sucrose ester given by the average value of the number of esterified fatty acid molecules per one sucrose molecule being within the range of 1.0 to 1.8, 5 to 30 parts by weight of sodium malate and 50 to 90 parts by weight of water.
Claim 7
Dependent Claim
88 words
An aqueous detergent composition having a good and stable transparency consisting essentially of 5 to 20 parts by weight of a sucrose ester of a saturated or unsaturated fatty acid having from six to 22 carbon atoms, the degree of substitution of said sucrose ester given by the average value of the number of esterified fatty acid molecules per one sucrose molecule being within the range of 1.0 to 1.8, 5 to 30 parts by weight of sodium malate and 50 to 90 parts by weight of water.
