Embodiment

[0031] The following are non-limiting examples of detergent compositions of the present invention. These examples are given for the purpose of illustration only, and should not be construed as limiting the present invention, because many changes can be made without departing from the spirit and scope of the present invention. In these examples, all concentrations are percent by weight unless otherwise specified.

[0032] A detergent composition, the following technical scheme can be adopted

[0033]

[0034]

[0035] Preparation process (1) Heat 60%-80% of the total amount of deionized water to 40-50°C, place it in a chemical tank, add a proportioning amount of sodium hydroxide to dissolve, add alkylbenzenesulfonic acid, Stir the lauric acid until it is completely dissolved, and adjust the pH to 7.0-8.0 to obtain a mixed solution A;

[0036] (2) In the mixed solution A, add sodium α-alkenyl sulfonate, sodium ethoxy (7) fatty acid methyl ester sulfonate (C18), fatty alc...

Abstract

The invention relates to a concentrated laundry liquid suitable for machine washing, and a preparation method thereof. The above washing agent composition comprises 8-14wt% of dodecylbenzene sulfonic acid, 9-12wt% of fatty alcohol polyoxyethylene ether (7-9), 6-10wt% of sodium ethoxylated (7) fatty acid (C18) methyl ester sulfonate, 2-10wt% of sodium alpha-alkenyl sulfonate, 1-3wt% of lauric acid, 1-2wt% of caprylyl / capryl glucoside, 3wt% of ethanol, 5wt% of propylene glycol, 1-5wt% of sodium citrate, 1-3wt% of an anti-redeposition agent Acusol845, a small amount of an essence and an antiseptic, and the balance water. The concentrated laundry liquid is slightly alkaline, is suitable for the machine washing of fabrics comprising cottons, hemps, synthetic fibers and the like, and has the characteristics of low temperature stability, strong decontamination force, low foaming, easy rinsing high cost performance and the like; and the concentrated laundry liquid has the advantages of high enrichment, no phosphorus, no fluorescent brightening agent, good biodegradability and environmental protection.

Description

technical field [0001] The invention relates to an alkaline detergent composition, in particular to a highly concentrated laundry liquid suitable for machine washing, and also relates to a preparation method of the laundry liquid. Background technique [0002] With the improvement of the quality of life and the change of consumption habits, on the basis of meeting the daily cleaning function of the family, safe, gentle, convenient to use, energy-saving and water-saving, and more environmentally friendly detergents have become the active guidance and promotion of the cleaning products industry and the attention and expectations of consumers.
