Aqueous detergent composition containing ethoxylated fatty acid di-ester
View Patent ↗Aqueous laundry detergent compositions comprising a solubilized ethoxylated fatty acid diester as a detergency booster and/or a defoamer. Preferred compositions include a nonionic surfactant, preferably ethoxylated fatty acid monoester, as at least part of the surfactant in the composition, and also functioning as the solibilizer for the ethoxylated fatty acid diester.
1. An aqueous isotropic liquid laundry detergent composition comprising:
(a) from about 0.1% to about 10%, by weight of the composition of a solubilized ethoxylated fatty acid diester;
(b) from about 5% to about 85%, by weight of the composition, of a detergent surfactant comprising at least about 2%, by weight of the composition, of a water-soluble nonionic surfactant comprising an alkoxylated alkyl monoester surfactant, wherein the weight ratio of the ethoxylated fatty acid diester to the water-soluble surfactant is in the ratio from about 4:1 to about 1:100;
(c) from about 15% to about 95% of water.
2. The composition of claim 1 , wherein the detergent surfactant amount is from about 10% to about 50%, by weight of the composition.
3. The composition of claim 1 wherein the foam height of the composition after 3 minutes of the test according to ASTM D1173-53 method is less than 5 cm.
4. The composition of claim 1 , wherein the nonionic surfactant comprises at least about 0.1%, by weight of the composition of the alkoxylated alkyl monoester.
5. The composition of claim 1 wherein the composition further comprises from about 0.1 to about 25% of an additional solubilizer for the ethoxylated fatty acid diester, selected from the group consisting of polyols, polyethylene glycol, ethylene glycol, propylene glycol, glycerin, ethanol, propanol and short-chain alkyl polyethylene glycols, hydrotrotropes, and mixtures thereof.
