Poly(ethylene glycol-ran-propylene glycol) monobutyl ether Chemical Properties,Usage,Production

Description

Poly(ethylene glycol-ran-propylene glycol) monobutyl ether is a block copolymer that consists of a hydrophilic poly(ethylene glycol) (PEG) segment and a hydrophobic poly(propylene glycol) (PPO) segment. One of the significant features of PEG-PPO monobutyl ether is its amphiphilic nature. This means that it has both hydrophilic and hydrophobic regions within its structure. This property allows PEG-PPO monobutyl ether to form micelles in aqueous solutions, where the hydrophobic PPO segments aggregate in the core while the hydrophilic PEG segments form the outer shell. The formation of micelles gives PEG-PPO monobutyl ether its surfactant properties. In pharmaceuticals, it is utilized as an excipient in drug formulations to improve solubility, stability, and controlled release of drugs. It can also be employed as a carrier for drug delivery systems, enhancing the bioavailability and targeting of therapeutic agents. Furthermore, PEG-PPO monobutyl ether finds applications in cosmetics as an emulsifier and solubilizer for various formulations. The mechanism of action of PEG-PPO monobutyl ether relies on its ability to self-assemble into micelles in aqueous solutions. When added to a system, the hydrophobic PPO segments aggregate together, forming a core, while the hydrophilic PEG segments create a protective shell around the core. This self-assembly process enables PEG-PPO monobutyl ether to solubilize hydrophobic substances and stabilize emulsions. It can also enhance the penetration and absorption of drugs through biological membranes.

Chemical Properties

liquid

Uses

Hydraulic fluids, metal working fluids and lubricants, heat transfer fluids, solder assist fluids, quenchants, lubricants, solvents, plasticizers and foam control agents.

Uses

Ucon? HTF 14 is a thermoseparating polymer (TSP) that can be used in aqueous two-phase extraction (ATPE) due to its decreasing solubility in its aqueous solution as the temperature rises. It is also used in a polymer coating on solid-phase microextraction (SPME) fibers using the sol-gel technique to impart thermal resistance and stability.
