Technical Field
The invention relates to the technical field of washing liquid, and particularly relates to a peroxide system sterilization laundry detergent and a preparation method thereof.
Background
At present, laundry detergent in the market basically has the functions of bacteriostasis and degerming, and products with the bactericidal efficacy are rare. Only a few commercially available laundry detergents with germicidal effect typically employ silver ions or cations as the germicidal system. The first type of laundry detergent based on a silver ion sterilization system has the following defects: (1) as the silver ions belong to heavy metal substances, the toxicological property is still questioned, the literature suggests that the addition amount of the silver ions of the product is less than 10ppm, and the products mainly used for sterilizing the silver ions in the market basically exceed the threshold value; (2) silver ions are easy to oxidize, so that the product is easy to blacken after being stored for a long time, and the appearance is influenced; (3) silver ions have a great negative effect on enzymes added in a plurality of laundry detergents, and can cause enzyme inactivation in a short time, thereby affecting detergency. The second type of laundry detergent based on a cationic sterilization system has the following defects: (1) the detergency of the laundry detergent of the cationic surfactant system is far inferior to that of the conventional anionic surfactant system; (2) the cationic system has strong skin irritation and cannot be used for hand washing; (3) the toxicity of the cationic sterilization system to protein is easy to cause enzyme inactivation, and the detergency is influenced; (4) cationic surfactants have poor biodegradability and are not environmentally friendly.

Detergent product performance testing method
1.1 stability test
Placing in a refrigerator with the temperature of minus 18 +/-2 ℃ for 24h to 4weeks for unequal time, taking out and recovering to the temperature of 4 ℃ to observe whether precipitation and discoloration phenomena exist, and testing the content of active oxygen and the like; placing the mixture in an incubator at 45 +/-2 ℃ for 24h-4weeks for different time, taking out the mixture and recovering to room temperature, observing whether the mixture has peculiar smell, delamination and discoloration phenomena, and testing the content of active oxygen and the like.
1.2 detergency test
Referring to the relevant steps of GB/T13174-2008, the detergency of the self-made sample plate is tested by using a RHQL type vertical decontamination machine to obtain decontamination ratio values (JB01, JB02 and JB 03).
1.3 anti-bacterial Performance test
The antibacterial performance of the detergent is tested by adopting an antibacterial detergent test method QB/T2738-2012. And (3) evaluating the stability of the antibacterial performance of the test sample by adopting an acceleration method. After the experimental sample is placed in a constant temperature box at 37 ℃ for 1 month, whether the antibacterial index of the experimental sample reaches a specified value is determined.
1.4 evaluation of safety
a. Colour of material body
Due to the high content of H in the system2O2The finished product of the laundry detergent is not recommended to be added with a pigment component, and the phenomenon of yellowing or fading of almost all pigments is found through long-term stable investigation.
b. Smell of material body
Also due to the higher content of H in the system2O2Essence components containing aldehyde carbonyl groups and terminal hydroxyl groups are not recommended to be added in a finished product material body system of the laundry detergent, long-term stable investigation shows that the essence is very easy to yellow or change the taste, and secondary hydroxyl essence components lacking high steric hindrance group protection are not recommended to be used.
C. Acting on metal objects
Also due to the higher content of H in the system2O2The finished laundry detergent product cannot be used for metal external packaging, and can not be used for washing clothes containing metal pigments or metal accessories, which can cause remarkable fading or tarnish of the metal accessories.

As shown by the results in FIG. 1, H increases with the pH of the system2O2Is drastically reduced and under weak acid conditions, H2O2The effective concentration does not change much.
2.2 evaluation of H by accelerated method2O2Initial content to H2O2Stability influence of
Configuration H2O2Seven experimental samples with initial mass contents of 0.35% (C0 ═ 0.35), 0.56% (C0 ═ 0.56), 1.06% (C0 ═ 1.06), 2.11% (C0 ═ 2.11), 3.13% (C0 ═ 3.13), 4.95% (C0 ═ 4.95), and 6.30% (C0 ═ 6.30), were sterilized in a peroxide system (other ingredients were the same as in example 10), and the experimental samples were stored at a constant temperature of 48 ℃2O2The change of the effective concentration (measured concentration/initial concentration) with time (day) was examined to find H in the system2O2Initial concentration of (2) to H2O2The results of the stability are shown in FIG. 2.
As shown by the results in FIG. 2, H in the system2O2The higher the initial concentration of (A), H2O2Stability may be reduced.
