| Abstract:Objective To establish a method to determinate dimeticone in type Ⅱ silicone gel by Infrared spectrophotometry. Methods The infrared spectrophotometry was adopted, and the detective wave was 1 262 cm-1. Results The linear range of the calibration of dimeticone was 0.409~2.863 mg/ml (r=0.999 9), the average recovery was 100.13%, RSD=1.02% (n=6). Conclusion The method was accurate, realizable which could be used to determinate dimeticone in type Ⅱ silicone gel. |
