These two methods were alkali in methanol and only ethanol washing. After both treatments, the PEs （phorbol esters） was decreased by 100%. The crude protein in detoxified meal of alkali in methanol washing was less amount than only ethanol washing. The result showed that treatment by only ethanol washing was a promising way to detoxify deoiled Jatropha curcas meal for animal feeds in industrial scale.展开更多

The dry/wet combability, surface contact angle, tryptophan content, and cuticle morphology of the smoke-exposed hair were evaluated, and compared to unexposed virgin hair. The results showed that pollution exposure can cause significant chemical damage to hair. In particular, virgin hair exposure to pollution can cause damage to the hair cuticles(higher wet/dry combing), protein degradation, and a more hydrophilic hair surface.展开更多

The cold resisting, heat resisting and freeze-thaw stability of liquid detergent were tested, and their foaming power, detergency, pH value as well as water-saving property were evaluated by Ross-Miles foam meter, Terg-O-tometer, pH detector and surface tensionmeter, respectively. The results showed that the ultra-concentrated liquid detergents product displayed excellent stability. pH value of liquid detergents were less than 9 with less skin irritation. The foaming power of 0.05% （weight fraction） of liquid detergents was appreciably lower than 0.2% standard liquid detergent.The detergency of 0.05% （weight fraction） of liquid detergents was better than 0.2% standard liquid detergent, especially for artificial sebum stained clothes; the water-saving of liquid detergents was better than standard liquid detergent, the surfactant concentration of second rinse solution of standard liquid detergent was 5.3 times than that of concentrated liquid detergent.展开更多
