Embodiment 1

[0095] Liquid detergent compositions were prepared based on the formulations shown in Table 1.

[0096] Table 1

[0097]

[0098] The foaming behavior of these liquid detergent compositions, including foam rinseability, was evaluated using the following procedure:

[0099] 1. Dilute 6.25 grams of liquid detergent composition with water to make 1 liter of cleaning solution.

[0100] 2. Introduce 50ml of cleaning solution into a 250ml graduated cylinder, shake the cylinder ten times.

[0101] 3. Carefully decant the liquid and measure the foam volume.

[0102] 4. Introduce 50ml of fresh water into the graduated cylinder to simulate a rinse and shake the graduated cylinder again.

[0103] 5. Repeat step 4 until the foam volume is less than or equal to 2ml.

[0104] The evaluation results are summarized in Table 2.

Abstract

The invention relates to a liquid detergent composition comprising: a) a first anionic surfactant which is an ethoxylated alkyl ether sulfate; b) a second anionic surfactant selected from the group consisting of C8-22 alkylbenzene sulfonates, C8-22 alkyl sulfates and combinations thereof; c) 0.1 to 2.5 % by weight based on the total weight of the liquid detergent composition of a fatty acid esteraccording to formula (II): R2-C(O)-O-R3 wherein R2 represents a linear C8-22 alkyl group; R3 represents a linear or branched C1-C4 alkyl group; d) at least 50 % by weight based on the total weight ofthe liquid detergent composition of water; wherein the first anionic surfactant and the second anionic surfactant together comprise 12 to 30 % by weight based on the total weight of the liquid detergent composition. This liquid detergent composition is very effective in removing soil from surfaces and, upon dilution with water, readily produces a cleaning liquid with a rich, creamy foam, which foam can easily be removed from the cleaned surface using only a limited amount of rinsing water.

Description

technical field [0001] The present invention relates to a liquid detergent composition which provides desirable sudsing and soil removal properties. More particularly, the present invention relates to a foaming aqueous detergent composition comprising: [0002] Ethoxylated alkyl ether sulfates; [0003] Alkylbenzenesulfonates and / or alkylsulfates; and [0004] · Fatty acid esters. [0005] Examples of liquid detergent compositions according to the invention include liquid hand dishwashing detergents and liquid hard surface cleaning compositions. [0006] When mixed with water, the liquid detergent compositions according to the invention readily form a cleaning solution with a rich, creamy foam. After cleaning, the foam can be easily removed from the cleaned surface by rinsing the surface with only a small amount of rinse water. Background technique [0007] Water is becoming an increasingly scarce commodity, especially in developing countries where it is not uncommon fo...
