Description

Strong decontamination type laundry detergent and preparation method thereof

Technical Field

The invention relates to the field of detergents, in particular to a powerful decontamination type laundry detergent and a preparation method thereof.

Background

The working principle of the laundry detergent is similar to that of the traditional washing powder and soap, and the active ingredients are all surfactants. The difference lies in that: the traditional washing powder adopts anionic surfactant which mainly comprises sodium alkyl sulfonate and sodium stearate, has strong alkalinity (the pH of the washing powder is generally more than 12), and further has great stimulation and damage to the skin when in use; the laundry detergent mostly adopts nonionic surfactants, the pH is close to neutral, the laundry detergent is mild to the skin, and after the laundry detergent is discharged into the nature, the laundry detergent is degraded faster than the laundry detergent, so the laundry detergent is gradually replaced to become a new-generation detergent.

The active ingredients of the laundry detergent are mainly nonionic surfactants, and the structure of the laundry detergent comprises a hydrophilic end and an oleophilic end, wherein the oleophilic end is combined with stains, and then the stains and fabrics are separated by physical movement (such as hand rubbing and machine movement). Meanwhile, the surfactant reduces the tension of water, so that the water can reach the surface of the fabric, and the effective components can play a role.

At present, clothes are cleaned by a washing machine, the contact time and action time of the laundry detergent and the clothes are limited, stubborn oil stains and protein stains such as sweat stains and blood stains on the clothes are difficult to effectively remove, so that the laundry detergent is difficult to clean the clothes with stubborn stains at one time and needs to be matched with hand washing.

This example differs from example 3 in that: the consumption of deionized water is increased due to the lack of components such as glucoside and calcium chloride.

Example 6

(1) preparing materials: weighing AE 0926 parts, AES 14 parts, KF-880.4 parts, ethylenediamine tetraacetic acid 1.5 parts, glucoside 1.8 parts, sodium dodecyl sulfate 4 parts, sodium citrate 0.6 parts, citric acid 0.8 parts, eucalyptus oil 2 parts, sodium chloride 0.8 parts, calcium chloride 0.4 parts and deionized water 19 parts in parts by mass for later use;

This example differs from example 3 in that: lacking the components liquid protease and lipase.

The laundry detergents prepared in examples 1-6 were tested for detergency, using national standard carbon black soiled cloth, national standard protein soiled cloth, and national standard sebum soiled cloth, with a washing concentration of 3g/L, a washing time of 30min, a temperature of 25 ℃, and the test results are shown in Table 1 below, wherein the numbers in the table represent detergency ratios:

	example 1	Example 2	Example 3	Example 4	Example 5	Example 6
							Carbon black dirt cloth	1.24	1.27	1.36	1.33	1.19	1.18
Protein dirty cloth	2.94	2.98	3.46	3.37	2.87	2.02
							Sebum dirt cloth	1.99	2.03	2.52	2.46	1.84	1.42

As can be seen from Table 1, the detergents prepared in examples 1-4 have higher detergency than the detergents prepared in examples 5 and 6; the cleaning power of the liquid laundry detergents prepared in examples 1 to 4 on the national standard protein dirty cloth and the national standard sebum dirty cloth is obviously higher than that of the liquid laundry detergent prepared in example 6 and slightly higher than that of the liquid laundry detergent prepared in example 5. Therefore, the addition of the liquid protease and the lipase can obviously improve the dirt-removing capacity of the laundry detergent on oil stains and protein stains.

And (3) stability testing:

after the laundry detergents prepared in examples 1 to 6 were stored for 5 months, sampling was performed again, and the results are shown in the following table 2:

	example 1	Example 2	Example 3	Example 4	Example 5	Example 6
							Carbon black dirt cloth	1.23	1.25	1.34	1.32	1.16	1.16
Protein dirty cloth	2.91	2.95	3.44	3.34	2.29	2.01
							Sebum dirt cloth	1.95	2.00	2.48	2.42	1.44	1.40

As can be seen from table 2, the detergency of the laundry liquids prepared in examples 1 to 4 and 6 to the national standard carbon black soiled cloth, the national standard protein soiled cloth and the national standard sebum soiled cloth is slightly reduced compared with that before 5 months; the detergent prepared in example 5 has slightly reduced dirt-removing power compared with that of national standard carbon black polluted cloth before 5 months, and has obviously reduced dirt-removing power compared with that of national standard protein polluted cloth and national standard sebum polluted cloth before 5 months. Therefore, the stability of the laundry detergent can be obviously improved by adding the glucoside and the calcium chloride and reducing the water content, and the shelf life of the laundry detergent is prolonged.
