A reaction device raising a generation yield by efficiently removing water generated in an esterified reaction between diethylene glycol monoethyl ether and succinic acid with mixture of an azeotropic point was newly developed as a new product in development of more stabilized emulsifier with a semi-solid phase(cream) in an emulsified phase of interfacial activity. The bis-(diethylene glycol monoethyl ether succinate(hereinafter, called as BDGS) with a high yield of more than 95% was obtained. As this has a property containing amphoteric emulsified functions such as W/O type or O/W type, etc., and has a merit that can be used regardless of any emulsified phase, there is no need using other emulsified surfactant. therefore, as this has excellent skin wetability in the cosmetics industry, a product having a wider range in quality compatibility or cost saving, etc. as a humectant has been developed.
