As a green multifunctional nonionic surfactant, alkyl glycoside has become an important raw material in daily washing industry. In the selected system, the preferred alkyl glycoside is apg1214, and the preferred dosage is 10%. Under these conditions, the addition of alkyl glycosides not only significantly improves the fluffy, softness and antistatic properties of laundry solution, but also has a synergistic effect on the detergency of laundry solution. With the deepening of research, alkyl glycosides will be more and more widely used in laundry detergent.

The foam end point washing method was used to prepare artificial dirt, plate and bubble position method to test the detergency instruments according to GB9985 - 2000 method. Weigh 4.0g of each detergent solution (LAS, Las, APG, AES, aes-apg, las-aes, las-aes-apg) with an electronic balance, pour 1000ml of 250PPM hard water into the enamel basin, and put 1000ml of 250PPM hard water into the lower bottle. At room temperature (25 degrees Celsius), open the outlet of the mouth bottle, and hard water flows into the basin to foam. When the hard water stopped flowing (about 45s), wash the dishes with 102mm pig brown paint. (wash the dishes with reference to GB9985 - 2000 detergency test method) until the foam completely disappears, record the number of washes and calculate the number of large plates.

Foaming is an important indicator of laundry detergents. Detergents usually require good foaming properties, stability and fine foams. However, the clothes cleaning wipes developed in this paper do not use water as solvent and require to rinse without water as much as possible, so the prepared products are required to be low foam or even non foam. It can be seen from table 3 that the foaming properties of the seven formulas are lower than those of the commercial laundry detergent, with good foam stabilizing effect, low viscosity and good stability, which roughly meets the basic requirements of this paper for low foam and non greasy laundry cleaning wipes. The requirements of down jacket cleaning wipes in this paper are stable performance, excellent decontamination effect, friendly to the environment, low bubble or even no bubble, and good use feeling.

APG is an active agent with high ecological safety. It will not produce toxic and harmful substances during synthesis and use, and its degradation speed is very fast. Xiao Wei studied the degradation rate of APG by oscillation method and closed bottle method. The results showed that when the biodegradation experiment was carried out for 9 days, the primary degradation degree was about 90%, and the final degradation degree had reached 70%. The degraded products would not cause damage to the ecology. Experiments show that APG combined with other active agents will improve the biodegradation rate and be harmless to the environment.
