Problems solved by technology

[0002] Laundry liquid produces a lot of foam during the washing process. Excessive foam will make cleaning difficult and affect the washing effect. The development of low-foaming liquid laundry detergent is a development trend
At present, most of the similar laundry detergents in the domestic and foreign markets are based on polyether surfactants or sodium stearate. Polyether surfactants are expensive, have poor low-foaming effects, and are difficult to thicken.
The single sodium stearate is unstable if the amount is too large, and the low foaming effect cannot be achieved if the amount is small

Embodiment 1

[0024] Embodiment 1: a kind of washing liquid, its component and mass parts thereof are:

[0025] Sodium laurate (CH 3 (CH 2 ) 10 COONa) 1 part;

[0026] Fatty acid polyoxyethylene ester (RCOO(CH 2 CH 2 O) n H) 11 copies;

[0027] 7 parts of linear sodium dodecylbenzenesulfonate;

[0028] 0.2 parts of gamma stilbene trisulfonic acid derivatives (BLF);

[0029] 0.1 parts of disodium ethylenediaminetetraacetic acid (EDTA-2Na);

[0030] Essence 0.1 parts;

[0032] 0.5 parts of sodium chloride;

[0033] 77.1 parts of deionized water.

[0034] Linear sodium dodecylbenzene sulfonate and alkanolamide are surfactants, gamma crystalline stilbene trisulfonic acid derivatives are fluorescent whitening agents, purchased from Shanghai Heliya Fine Chemical Co., Ltd., model: BLF, sodium chloride as thickener, disodium edetate as chelating agent.

Embodiment 2

[0035] Embodiment 2: the preparation method of the laundry detergent described in embodiment 1:

[0036] 1. Add 77.1 parts of deionized water and 1 part of sodium laurate in sequence, stir and heat up to 60°C-70°C, then add 0.1 part of EDTA-2Na, 11 parts of polyoxyethylene fatty acid ester, linear twelve 7 parts of sodium alkylbenzene sulfonate, 3 parts of alkanolamide, 0.5 part of sodium chloride, stirred to dissolve.

[0037] 2. Cool down to below 30°C, add 0.2 part of whitening agent BLF, 0.1 part of essence, stir to dissolve.

[0038] 3. Filter through a 300-mesh filter and pack.

Embodiment 3

[0039] Embodiment 3. a kind of laundry detergent, its component and mass parts thereof are:

[0040] 9 parts of sodium laurate;

[0041] Fatty acid polyoxyethylene ester 1 part;

[0042] 15 parts of sodium fatty alcohol polyoxyethylene ether sulfate;

[0043] 8 parts of fatty alcohol polyoxyethylene ether;

[0044] 0.1 part of distyrene biphenyl whitening agent (CBS-X);

Abstract

The invention relates to a detergent. The invention discloses a low-foam fabric cleaner; the main active ingredients of the cleaner and the parts by weight thereof are as follows: 1-9 part(s) of sodium laurate, 1-11 part(s) of polyoxyethylene carboxylate fatty acid ester, 10-25 parts of surface active agent, 0.1-1 part of chelating agent and 0.5-5 part(s) of thickening agent. The complex formulation of sodium laurate and polyoxyethylene carboxylate fatty acid ester can lower the foaming power of other surface active agents, thus achieving the function of reducing foam. The low-foam fabric cleaner is easy to rinse, water-saving and energy-saving, and has strong detergency.

Description

technical field [0001] The invention relates to a detergent, in particular to a low-foaming laundry detergent. Background technique [0002] Laundry liquid produces a large amount of foam during the washing process. Excessive foam will cause cleaning difficulties and affect the washing effect. It is a development trend to develop low-foaming liquid laundry detergent. At present, most of the similar laundry detergents in the domestic and foreign markets are based on polyether surfactants or sodium stearate. Polyether surfactants have high cost, poor low-foaming effect, and are difficult to thicken. A single sodium stearate is unstable if the amount is large, and the low foaming effect cannot be achieved if the amount is small. The sodium laurate selected for use in the low-foaming laundry detergent of the present invention is better in water solubility, has stronger detergency and good defoaming effect, and polyoxyethylene fatty acid ester has good emulsification, cleaning, ...
