Embodiment 1

[0087] Example 1: Effect of specific combinations of lauric and stearic acids on lather volume

[0088] In this example, the foam volume generated in the initial wash and the defoaming effect during rinsing by the composition of the invention (Ex1) were compared with those of the comparative compositions (C2 to C15) comprising various other fatty acids and their combinations Compare.

[0089] Table 2

[0090]

[0091] *13.50% LAS+3.94% SLES 2EO+0.56% CAPB

[0092] The table above shows that the composition of the invention (Ex1 ) performs best when compared to any other composition (C2 to C15) comprising fatty acids outside the scope of the invention. It should be noted that Ex1 maintained the same initial lather as the control (C1 ) and required fewer rinse cycles than the other compositions.

Embodiment 2

[0093] Example 2: Effect of each component of the composition on lather volume

[0094] In this example, the foam volume produced in the initial wash and the defoaming effect during rinsing by the composition of the invention (Ex1) were compared with a comparative combination comprising only one component of the composition (C16 and C17 )Compare.

[0095] table 3

[0096]

[0097] *13.50% LAS+3.94% SLES 2EO+0.56% CAPB

[0098] The table above shows that the composition of the invention (Ex 1 ) performs better than the composition lacking one of the components in terms of number of rinse cycles and initial lather volume.

Embodiment 3

[0099] Example 3: Effect of Concentration of Fatty Acid Combination on Lather Volume

[0100] This example shows the effect of the concentration of the combination of fatty acids on the suds volume generated in the initial wash and the defoaming effect during the rinse. The example compositions Ex1 and Ex2 were compared with comparative compositions (C18 and C19) comprising combinations of fatty acids at concentrations outside the range of the invention.

[0101] Table 4

[0102]

[0103] *13.50% LAS+3.94% SLES 2EO+0.56% CAPB

[0104] The table above shows that the best results for initial foaming and antifoaming during rinsing are obtained at fatty acid combination concentrations within the range of the present invention. The table above also shows that at higher fatty acid combination concentrations, the initial foam was compromised (C18 and C19).

Abstract

The field of the present invention is that of liquid detergent compositions which have foaming and cleaning properties in the main wash, yet have a significant reduction in foaming during the rinsing process. Challenges exist in providing consumers with cleaning compositions that maintain initial lather while exhibiting a defoaming effect during rinsing. It is therefore an object of the present invention to provide a defoaming effect during rinsing while maintaining foaming properties during the main wash. It has been found that this object can be achieved in hard surface cleaning processes by liquid detergents comprising a surfactant system having a primary surfactant and a secondary surfactant, saturated from lauric and stearic acids. A combination of fatty acids and nonionic surfactants.

Description

technical field [0001] The field of the invention is hard surface cleaning compositions, in particular liquid detergent compositions, which have sudsing and cleaning properties in the mainwash, however, sudsing is significantly reduced during rinsing. Background technique [0002] Water is becoming an increasingly inaccessible commodity, especially in developing countries where it is not uncommon for people to travel many kilometers to reach water sources. Therefore, there is an increasing need to conserve water. [0003] One way to save water is to reuse it, while another way is to reduce the amount of water used. [0004] Laundry processes, including laundry, dishwashing, and other household cleaning processes, require vast amounts of water throughout the world. These are everyday chores where the use of water and detergent cannot be avoided. Consumers generally like to see a lot of suds when washing because they associate suds with detergent efficiency. However, its f...
