usage:
polyethylene glycol (peg) series of products can be used for potions.low relative molecular weight of polyethylene glycol (peg) can be used as a solvent, cosolvent, o/w emulsifier and stabilizer, suspension, emulsion, used to make cement injection, etc., are also used as a water-soluble ointment and suppository matrix, the matrix of high relative molecular weight solid waxy polyethylene glycol (peg) is often used to increase the peg viscosity and low molecular weight liquid to solid, and of other drugs;for drugs to dissolve in water, this product can make solid dispersing agent of the carrier, solid dispersion in order to achieve the purpose.
