Domestic substitution of medical-grade white oil
A domestic pharmaceutical company was blocked from importing medical-grade white oil, and Ranze Energy launched an emergency R&D project. The technical team, in conjunction with Sinopec Research Institute, used five-level molecular distillation technology to control the aromatic content of the product to below 0.005%, and the heavy metal residue was less than 0.1ppm, meeting the USP pharmacopoeia standard. After 6 months of stability testing, the compatibility of the white oil in the ointment matrix exceeded that of imported products, helping customers to achieve localization of raw materials and reducing the cost of a single batch by 42%.
