Embodiment 1

[0160] Example 1: Comparative test showing the foaming properties of the composition of the invention

[0161]Seven (7) exemplary granular laundry detergent formulations with varying levels of fatty acid sodium salts were prepared to demonstrate the effect of fatty acid content on the lathering performance of laundry detergent compositions. These exemplary formulations include: (1) 1 control formulation C1 containing 0% fatty acid sodium salt; (2) 1 comparative formulation C1 containing a relatively low level of 1.5 wt% fatty acid sodium salt; (2) 5 formulations of the present invention, E1, E2, E3, E4 and E5, comprising fatty acid sodium salts in an amount of about 2% by weight or more. The compositional breakdown of these formulations is shown in Table 1:

Abstract

The present invention provides a cleaning composition comprising high fatty acids. Specifically, the present invention provides a cleaning composition, preferably a particulate laundry detergent composition, comprising a relatively high content of a fatty acid or a salt thereof in a specific surfactant system comprising a C10-C20 linear alkylbenzene sulfonate (LAS) and a C6-C18 non-alkoxylated alkyl sulfate (AS) in a weight ratio from 3: 1 to 24: 1. The higher levels of fatty acids or salts in such surfactant systems surprisingly result in better foaming profiles.

Description

technical field [0001] The present invention relates to cleaning compositions, preferably granular laundry detergent compositions, having satisfactory lathering and / or cleaning properties. In particular, such cleaning compositions employ relatively high levels of fatty acids or salts thereof in a particular surfactant system to provide optimized lather characteristics. Background technique [0002] Although automatic washing machines are widely accepted and used in modern homes, there are still many situations where people need to resort to hand washing, such as when delicate clothes or stubborn stains are involved and special care is required. In fact, in most developing countries, consumers still wash their clothes by hand in a tub or tub, which involves washing with detergent, wringing out or spinning, and rinsing one or more times with water. step. [0003] Foaming characteristics of detergent compositions include, but are not limited to: speed and volume of foam produ...
