Performance and application:
1. Polyethylene glycol series products can be used in pharmaceuticals. Polyethylene glycol with a relatively low molecular weight can be used as a solvent, co-solvent, o/w emulsifier and stabilizer to make cement suspensions, emulsions, injections, etc., and can also be used as a water-soluble ointment base and suppository base. Solid waxy polyethylene glycol with high relative molecular weight is often used to increase the viscosity and solidification of low molecular weight liquid PEG, and to compensate for other drugs; for drugs that are not easily soluble in water, this product can be used as a carrier for solid dispersants to achieve Solid dispersion purpose.Specification | Appearance ( 25ºC ) | Color ( Pt-Co ) | Hydroxyl value ( mgKOH/g ) | molecular weight | Freezing point ( ºC ) | Moisture ( % ) | pH Value ( 1% aqueous solution ) |
PEG-400 | Colorless transparent liquid | ≤20 | 255~312 | 360~440 | 4~10 | ≤1.0 | 5.0~7.0 |
PEG400 is packed in 200kg iron drum or 50kg plastic drum.
This series of products are general chemicals, non-flammable, and should be stored and transported as general chemicals. Store in a dry and ventilated place. Shelf life is two years.
