US Morflex one-step synthesis

US Morflex founded in 1927, located in Greensboro, United States, is the world's largest manufacturer of N,N-Diethyl-3-methylbenzamide . It owns 40 years of production and sales of N,N-Diethyl-3-methylbenzamide history, providing 60 percent of global consumption. Users include Johnson, Bayer and other famous enterprises, Morflex repellent cream formulation has cosmetic properties, non-irritating to human skin, more even applied than alcohol formula , more comfortable, no dry and tight and not greasy sense after the use of alcohol formula, specially formulated to lock N,N-Diethyl-3-methylbenzamide in sweat, friction, etc., can maintain long-lasting efficacy. Its production methods can be called "one step synthesis" , the advantage of "one step synthesis" is that it does not produce chemical synthesis additions-phosphoric acid, hydrochloric acid, amine hydrochloride or benzene. Phosphoric acid can cause greasy products, and other impurities are either irritating to the skin, or harmful to the human body. The multi-step synthesis methods currently used in the country can not avoid these harmful chemicals addenda.
