The effects of water-soluble polymers on nanoparticle formation of piroxicam and pranoprofen were investigated. We also studied the effects of propylene glycol (PG) concentration in PG aqueous solution on skin permeation of the drugs from nanoparticles. Physical mixtures (PMs) of the drug, ...
propylene oxide is an intermediate of the herbicide metolachlor, and is also an important organic synthesis chemical raw material, propylene glycol, allyl alcohol, propionaldehyde, isopropylamine, synthetic glycerin, organic acids and the like can be produced, and Nonionic Surfactants, wetting agents, ...
Useorganic synthesis intermediates. Mainly used in the manufacture of propylene oxide and propylene glycol. It is widely used in the production of polyurethane and other unsaturated polyester resins. Medicinal for the synthesis of chlorpromazine. ...
In topical applications, propylene carbonate has been used in combination with propylene glycol as a solvent for corticosteroids. The corticosteroid is dissolved in the solvent mixture to yield microdroplets that can then be dispersed in petrolatum.Propylene carbonate has been used as a dispensing solven...
1. The phosgene process raw material propylene glycol reacts with phosgene to generate hydroxyisopropyl chloroformate, and then reacts with sodium hydroxide to generate propylene carbonate, which is then distilled under reduced pressure to obtain a finished product. 2. Transesterification method. 3. Th...
