Abstract


Detergent is necessary in our daily lives. Along with the improvement of living standards and the enhancement of environmental awareness, people pay more attention to health and safety, and bring forward more request on the detergent. Based on the perspective of sustainable development, chemical industry will adjust its industrial structure, develop the "environmentally-friendly" section including cleaning industry in twenty-first century. Besides to meet people’s basic requirments, such as high cleaning ability, safety, economic, non-irritating etc, detergent should aslo comply with environmental, moderate and other requirements. Sodium tripolyphosphate bring on "eutrophication", which caused in "banned phosphorus, restricted phosphorus" campaign. So developing non-phosphorus additives with excellent washing performance as sodium tripolyphosphate become a research hotspot. Automatic dishwasher with cleaning, disinfection decontamination and drying multiple functions, it’s appearance can help people to achieve their dreams of liberating from home simple, repetitive dishwashing. In China, the research of detergent for Automatic dishwasher is just in its youth, therefore, developing a new detergent matched the machine has a very practical and prospect significance.Based on the special point of dishwash products in China market, and to meet the demands of consumer to the dishwash with high efficiency and safety, so conduct the captioned study. The article also introduced the detergent of current status, and dissertated the meanings of the study. The experiment selected alkyl polyglycosides(APG) as the main surfactant, through Shaked-flask volume method, Cloud Point measured, study the physical and chemical properties of surfactants and the compound effects, used the standard of low-foam, low cloud point get the amount of surfactant formulations. Bulider selecd sodium citrate, sodium carbonate, sodium silicate, By using orthogonal design, GB/T 24692 geted the amount of additives. Combined with GB/9985, GB/T 15357, biodegradation test to evaluate the choice and formula dosage and compatible system of main surfactant, secondary surfactant, addititive and thickener. As the reshlt of the experiment, chose the components such as APG, Fatty alcohol ethoxylates( AEO9), Polydimethyl siloxane fluid, sodium citrate, and develop the environmentally-friendly detergent with good stability, cleaning powder, low foam, easy rinse, anti-micro. It can matched the automatic dishwasher, it also meet the request of GB of detergents for dishwashing.According to the experiment, the optimized formula is APG 1.5%, AEO9 0.5%, Polydimethyl siloxane fluid 0.5%, sodium citrate 13%, Sodium polyacrylate 2.6%, Sodium Carbonate 6%, Sodium Silicate 7%, Bleach 1%, Gum Arabic 0.7%, Lipase 0.5%, Amylase 0.5%, Lemon flavor 0.15%, Purified water.
