Non ionic contrast medium is the second generation of CT contrast medium. For advantages of non ionic contrast media, compared with the first generation of ionic contrast medium, the non ionic contrast medium has greater water solubility. In addition, it does not ionize in water, which has the advantages of low viscosity and low osmotic pressure. Clinically, the incidence and severity of toxic side effects of the non-ionic contrast medium are significantly lower than that of the ionic contrast medium.

The main component of CT/X-ray Contrast Media is iodine. The Iodinated Contrast Media is a colorless, transparent, slightly viscous liquid. At present, the contrast agents used in CT can be mainly divided into ionic and non-ionic, according to the osmotic pressure can be divided into hypertonic, isotonic and hypotonic. Currently, non-ionic, isotonic or hypotonic Contrast Media are used clinically. When the CT contrast medium is injected, 97% of the contrast media products can be directly excreted from the kidneys within 1 day. Apart from contrast media products, we also provide calcobutrol sodium for different use.

Dyes are compounds that can impart bright and durable colors to other substances in a molecular or dispersed state. In the printing and dyeing process, besides using raw dye powder, dye auxiliaries are also added to enhance dyeing efficiency and effectiveness. Among these auxiliaries, dye dispersants play a vital role. Dye dispersants are non-ionic surfactants that aid in achieving a leveling effect, maintaining dye dispersion, preventing aggregation and precipitation, and improving dye solubility. By incorporating dispersants and protective colloids, uniform dyeing is ensured, and stains are prevented.
