Various types and uses of polyethylene glycol
PEG-200: It can be used as a medium for organic synthesis and a hot carrier with high requirements. It is used as a moisturizer, inorganic salt solubilizer and viscosity modifier in the daily chemical industry. It is used as a softener and antistatic in the textile industry. Agent; used as a wetting agent in the paper and pesticide industry.
PEG-400 is best for soft capsules. Since PEG400 is a liquid, it has wide compatibility with various solvents, is a good solvent and solubilizer, and is widely used in liquid preparations such as oral liquids, eye drops, and the like. PEG is the material of choice when vegetable oils are not compatible with active ingredient carriers. This is mainly because PEG is stable and not easily deteriorated, and the PEG-containing injection is safe and stable when heated to 150 degrees Celsius. In addition, it can be mixed with high molecular weight (PEG) and its mixture has good solubility and good drug compatibility.
PEG-1000, PEG-1500: used as a matrix or lubricant, softener in the pharmaceutical, textile and cosmetic industries; used as a dispersant in the coating industry to improve the water dispersibility and flexibility of the resin, the dosage is 10-30 %; The ink can improve the solubility of the dye and reduce its volatility. It is especially suitable for use in stencil and pad inks. It can also be used to adjust the viscosity of ink in ballpoint pen inks. It is used as a dispersant in the rubber industry to promote vulcanization. Used as a dispersant for carbon black fillers.
PEG-4000 and PEG-6000 are used as excipients in the pharmaceutical industry for the preparation of suppositories and ointments; as a finishing agent in the paper industry, to increase the gloss and smoothness of paper; as an additive in the rubber industry, to increase the lubrication of rubber products Sex and plasticity, reduce power consumption during processing, and extend the service life of rubber products.
Used as a matrix in the production of pharmaceuticals and cosmetics industry, it plays a role in adjusting viscosity and melting point; as a lubricant and coolant in rubber and metal processing industries, as a dispersant and emulsifier in the production of pesticides and pigments; Used as antistatic agent, lubricant, etc. in the textile indus
