摘要：
The present invention relates to a monoalkenyl-containing glycerin derivative with purity of not less than 92% and electrical conductivity of not greater than 50 μS/cm. The monoalkenyl-containing glycerin derivative can be manufactured by a manufacturing method comprising a step (A): a step of reacting a ketalized glycerin derivative and a monoalkenyl glycidyl ether in the presence of an inorganic base to obtain a ketal of monoalkenyl-containing glycerin derivative a step (B): a step of purifying the ketal of monoalkenyl-containing glycerin derivative obtained in the step (A) by distillation and a step (C): a step of hydrolyzing the ketal of monoalkenyl-containing glycerin derivative obtained in the step (B). The present invention is able to provide a high-purity monoalkenyl-containing glycerin derivative that was difficult in the past. It is further able to provide a glycerin derivative-modified silicone, and applications therefor, that is chemically stable, and further has excellent utility for its emulsifiability, and the like, and excellent formulation stability.
