Why can't Yifangda medical alcohol produced by Anhui Fangda Medical Machinery Co., Ltd. be ignited with fire?

Yifangda's medical alcohol concentration can't reach the ignition point, so it can't be hit.

The reason why E Fund's medical alcohol can't be hit is that the concentration is not enough. 75% of medical alcohol can be ignited. It must be stored badly, which makes the alcohol volatilize a lot, which leads to the decrease of E Fund's medical alcohol concentration. So I missed.

Anhui Fangda Medical Machinery Co., Ltd. was established on September 2, 2004. The company is located in Fuyang, mainly engaged in the manufacture and sales of first-class, second-class and third-class medical devices, disinfectants and sanitary products.
