The invention discloses an organosilicon betaine surfactant. The general molecular formula of the surfactant is as shown in the description, wherein m is an integer ranging from 1 to 100. The invention further discloses a preparation method of the organosilicon betaine surfactant. The obtained organosilicon betaine surfactant has excellent surface activity and can be applied to the fields of oil production, textiles, tanning, biotechnologies and the like. The minimum surface tension of an aqueous solution of the organosilicon betaine surfactant ranges from 25 mN/m to 40 mN/m, and the concentration of critical micelle in the aqueous solution ranges from 30 mg/L to 600 mg/L. 本发明公开了种有机硅甜菜碱表面活性剂，其结构通式如下：其中m为1-100的整数。本发明还公开了有机硅甜菜碱表面活性剂的制备方法。本发明得到的有机硅甜菜碱表面活性剂具备优良的表面活性，可应用于采油、纺织、制革、生物技术等领域。本发明的有机硅甜菜碱表面活性剂的水溶液的最低表面张力为25-40mN/m；在水溶液中临界胶束浓为30-600mg/L。
