[0106] The preparation of fabrics with DCO is carried out:

[0107] · Using 100 grams of peanut oil at 150 ° C to 180 ° C, 20 grams of salted fish oil was bombed 2 hours to form a dirty cooking oil (DCO).

[0108] • 0.6 ml of DCO brush to the center of 10 cm * 10 cm cotton fabric to form a circular stain (D = 5 cm).

[0109] • Cut the 10 cm * 10 cm cotton fabric is 4 equal slices and uses a performance assessment. )

[0110] 7. Pour 250 ml of sample solution into the beaker from the drum, and 750 ml of water having a level of hydraulic levels mentioned above is added to the beaker to form a total volume of about 1 liter of 1 / 4 dilution solution. .

Embodiment 1

[0139] Example 1: Comparison Testing of Bubble Features

[0140] Two granular laundry detergent formulations having two different fatty acid blends were prepared to show the effect of fatty acids to form a foaming property of the laundry detergent formulation. First, a comparative example particle-shaped laundry detergent composition employs a fatty acid blend, the fatty acid blend comprises from about 10% by weight of PKO derived fatty acid salt (sodium) and about 90% by weight of PO-derived fatty acid salt. (sodium). Second, the particulate laundry detergent composition of the present invention employs a fatty acid blend, the fatty acid blend comprises from about 20% by weight of PKO-derived fatty acid salt (sodium) and about 80% by weight of PO-derived fatty acids. Salt (sodium). The composition decomposition of these two formulations is shown in Table I:

[0149] Example 2: Contrast test of the residue of the fabric after washing

[0150] Four (4) particulate laundry detergent preparation samples having two different fatty acid blends were prepared to show the effect of fatty acids to form a non-dissolved fabric residue of the laundry laundry detergent formulation. The components of these four-part preparation are shown in Table III:

Abstract

The present invention discloses a cleaning composition, preferably a granular laundry detergent composition, which comprises a fatty acid or a salt thereof in a weight ratio of 3:1 to 50:1 C 10 -C 20 Linear alkylbenzene sulfonate (LAS) and C 6 -C 18 Blending in specific surfactant systems of unalkoxylated alkyl sulfates (AS). The mixture of fatty acids or salts comprises 15% to 30% fatty acids or salts derived from palm kernel oil and / or coconut oil and 70% to 85% fatty acids or salts derived from palm oil. Such mixtures of fatty acids or salts in particular surfactant systems can provide improved sudsing characteristics during washing and can also reduce insoluble residue on washed fabrics.

Description

Technical field [0001] The present invention relates to a cleaning composition, preferably a particulate laundry detergent composition. Background technique [0002] Although the automatic washing machine has been widely accepted and used by modern families, there are still many situations that need to be washed, for example, special care when it involves impaired clothes or stubborn stains. In fact, in most developing countries, consumers' clothing washing habits are still wash their clothes in the basin or bucket, which includes washing, unpacking or rotating with detergents, and rinsing or rinked with water or multiple times. step. [0003] The foaming characteristics of the cleaning composition is especially important for consumers who are still washing their clothes and fabrics because their washing experience is directly affected by the foaming characteristics, the foaming features include, but are not limited to, dissolving in the washing solution. The speed and volume of ...
