Embodiment

[0165] Prepare the following composition :

[0166]

[0167] 1 Zwitterionic ethoxylated quaternized sulfated hexamethylenediamine supplied by BASF, Germany

[0168] 2 A polyvinyl acetate grafted polyethylene oxide copolymer with a polyethylene oxide backbone and multiple polyvinyl acetate side chains was supplied by BASF, Germany.

[0169] As can be seen from Comparative Examples 1 and 3, formulation of laundry detergent compositions without ethanol results in high viscosity which leads to processability issues, undesirable pour viscosity and residue in the washing machine. As can be seen from Examples 2 and 4, by adding zwitterions, the resulting laundry detergent composition has a manageable viscosity profile, with a pouring profile being more desirable, and does not produce residue that remains in the washing machine after use, -- even if the composition does not contain any solvent.

[0170] Prepare the following composition :

[0171]

Embodiment 7

[0172] The composition of Example 7 was stable without phase splitting even after centrifugation. In contrast, the composition of Example 8 was not phase stable, with a clear separation of the surfactant-rich and low-surfactant phases.

[0173] Examples 9 to 12 are non-limiting embodiments of the invention. All percentages are by weight unless otherwise indicated.

[0174]

[0175] 3 Mannanase derived from Bacillus sp. I633 was purchased from Novozymes, Denmark

[0176] 4 Ultra, from Novozymes, Denmark

[0177] 5 Protease from Bacillus amyloliquefaciens as described in EP 0 130 756 B1 published 9 January 1985

[0178] 6 Novozymes from Denmark

Abstract

Liquid detergent composition which comprises an effective cleaning amount of surfactant, while still being pleasingly free-flowing, and which does not require high levels of organic, non-aminofunctional solvents in order to control the viscosity, can be formulated using a zwitterion, especially a zwitterionic polyamine.

Description

technical field [0001] Low solvent liquid detergent composition. Background technique [0002] In order to provide good cleaning, liquid detergent compositions generally contain appreciable amounts of detersive surfactants, with the result that at least part of the surfactant system is present in the worm-like or liquid crystalline phase. When there is sufficient surfactant to form micelles (concentration above the critical micelle concentration or CMC), for example spherical, cylindrical (rod-shaped) or disc-shaped micelles can be formed. As the surfactant concentration increased, a worm-like micellar phase was formed. At higher surfactant concentrations, liquid crystalline phases such as lamellar, hexagonal or cubic phases may form. The lamellar phase consists, for example, of alternating surfactant bilayers and aqueous layers. These layers are usually not flat, but folded to form submicron spherical onion-like structures called vesicles or liposomes. On the other hand...
