Embodiment 1

[0049] Preparation of synthetic detergent: preparation of environmentally friendly synthetic detergent 100.00g

[0050] First, the liquid preparation 7.14g of fatty alcohol polyoxyethylene ether sodium sulfate with a solid content of 70%, 50.00g of polyepoxysuccinic acid with a solid content of 40%, and 37.50g of a linear alkyl benzene sulfonic acid with a solid content of 40% After the sodium is evenly mixed, place it in a dryer and bake at 105°C for 2 hours. After taking it out, add 1.00g polyvinylpyrrolidone, 5.00g sodium bicarbonate, 5.00g borax, 10.00g sodium silicate, 0.20g fluorescence enhancement. The whitening agent VBL is supplemented with sodium sulfate to a weight of 100.00g to obtain an environment-friendly synthetic detergent 100.00g.

[0051] The experimental results are shown in Table 1.

Embodiment 2

[0053] Preparation of synthetic detergent: preparation of environmentally friendly synthetic detergent 100.00g

[0054] First, the liquid preparation 10.00g of fatty alcohol polyoxyethylene ether sodium sulfate with a solid content of 70%, 50.00g of polyepoxysuccinic acid with a solid content of 40% and 37.50g of a linear alkyl benzene sulfonic acid with a solid content of 40% After the sodium is evenly mixed, place it in a dryer and bake at 105°C for 2 hours. After taking it out, add 1.00g polyvinylpyrrolidone, 5.00g sodium bicarbonate, 5.00g borax, 10.00g sodium silicate, 0.20g fluorescence enhancement. The whitening agent VBL is supplemented with sodium sulfate to a weight of 100.00g to obtain an environment-friendly synthetic detergent 100.00g.

[0055] The experimental results are shown in Table 1.

Embodiment 3

[0057] Preparation of synthetic detergent: preparation of environmentally friendly synthetic detergent 100.00g

[0058] First, the liquid preparation 12.86g of fatty alcohol polyoxyethylene ether sodium sulfate with a solid content of 70%, 50.00g of polyepoxysuccinic acid with a solid content of 40%, and 37.50g of a linear alkyl benzene sulfonic acid with a solid content of 40% After the sodium is evenly mixed, place it in a dryer and bake at 105°C for 2 hours. After taking it out, add 1.00g polyvinylpyrrolidone, 5.00g sodium bicarbonate, 5.00g borax, 10.00g sodium silicate, 0.20g fluorescence enhancement. The whitening agent VBL is supplemented with sodium sulfate to a weight of 100.00g to obtain an environment-friendly synthetic detergent 100.00g.

Abstract

The invention belongs to the daily chemical industry technical field, in particular to an environmental friendly synthetic detergent taking poly epoxy succinic acid as a washing assistant. The synthetic detergent comprises the following components according to the percentage by weight: 8%-15% of linear alkylbenzene sulphonic acid, 10-30% of poly epoxy succinic acid, 1%-5% of fatty alcohol polyoxyethylene ether (polyoxyethylene fatty alcohol sodium sulfate), 4%-6% of sodium bicarbonate, 4%-6% of borax, 0.5%-1.5% of polyvinyl-pyrrolidone, 5%-12% of sodium silicate, and 0.03%-0.2% of optical brightness VBL, and the rest of bulking agent sodium sulfate, which meets the gross weight of 100%. The poly epoxy succinic acid used by the synthetic detergent as the washing detergent plays a part in anti redeposition and dispersion, not only can chelate with metal ions such as calcium, magnesium and the like but also has dispersive action on calcium and magnetism precipitation, thus achieving the effect of anti redeposition and dispersion and increasing the washing effect. All components in the synthetic detergent have good synergistic action and obvious decontamination and anti redeposition effects. The environmental friendly synthetic detergent does not contain nitrogen and phosphorus, and the poly epoxy succinic acid can be biodegraded; therefore, after being used, the synthetic detergent does not cause the severe harm to the environment.

Description

Technical field [0001] The invention belongs to the technical field of daily chemical industry, and specifically relates to an environment-friendly synthetic detergent using polyepoxysuccinic acid as a washing aid. Background technique [0002] Clothes washing is one of the indispensable important links in daily life. It is an important means to keep the body healthy and increase the reuse rate of clothes. Its purpose is to restore dirty clothes to a usable state through washing. When cleaning dirty clothes, oil stains, sweat stains and other stains attached to the clothes are difficult to achieve a good removal effect only by rinsing with clean water. The detergent can reduce the adhesion of dirt on the fiber surface through wetting, penetration, emulsification, dispersion, foaming, solubilization, etc., and then remove it by mechanical force. Therefore, in order to improve the decontamination effect when washing clothes, it is necessary to add detergent when washing clothes. ...
