The international definition of VOC is a compound composed of carbon element combined with one or more nitrogen, oxygen, hydrogen, sulfur, phosphorus, silicon or halogen (fluorine, chlorine, bromine, iodine), and its vapor pressure is 20cc or operating conditions. Exceeds 0.01kPa and no chemical change occurs �．瑞士除了考虑化学物质的蒸汽压外，还规定在标准压力下的沸点≤24�� degrees without chemical changes, which is the basis for quantitative analysis of VOCs. Usually, a combination of instruments can be used for analysis.

DHTDMAC, DSDMAC and DTDMACare all cationic surfactants and are raw materials for making softeners. Although the softeners made from them have excellent softening effects, they will kill biological bacteria. Biodegradability is very poor and can easily be absorbed by sludge during sewage treatment and pollute agricultural products. �。因此，在20世纪90年代初已在德国、荷兰等国家停止使用，近年欧盟决定禁止使用.
