What Are Polyethylene Glycol Derivatives?

Polyethylene glycol derivatives are high polymer mixtures made of ethylene glycol dewatering by molecular dehydration. Depending on the size of the relative molecular mass, the physical form of polyethylene glycol derivatives can be from white mucus to waxy semi-solid to hard waxy solids. Polyethylene glycol derivatives are soluble in most high-polarity organic solvents, such as alcohol, alcohol-silicon mixture, diol, ester, ketones, aromatherapy, nitrone, and so on. 

The solubility of polyethylene glycol derivatives is related to the level and temperature of their relative molecular quality. Liquid polyethylene glycol can be dissolved in water at any proportion, while solid polyethylene glycol has only a limited solubility, but even the polyethylene glycol with the maximum level of the relative molecular mass, the solubility in the water is still greater than 50%. The temperature increases and the solubility of solid polyethylene glycol increase sharply. When polyethylene glycol is mixed with water, a slight volume contraction occurs, and it is significantly inspired. In addition, polyethylene glycol is also soluble in monomers of low-grade aldehyde, amine, organic acids, acid anhydrides, and polymers. But it is insoluble in compounds containing long hydrocarbons such as rapeseed oil and mineral oil.

Applications of PEG Derivatives

The application of polyethylene glycol derivatives in the cosmetics industry and pharmaceutical industry is widely used. Because polyethylene glycol has a lot of excellent properties: water-soluble, volatile, physiological inertia, mildness, lubricating, etc. The viscosity, hygroscopic, and tissue structure of different relative molecular quality divisions can be adopted. The relative molecular mass of polyethylene glycol derivatives is suitable for moisturizing agents and consistency regulators, for cream, lotion, toothpaste, and shaving cream. Relative molecular quality polyethylene glycol derivatives are suitable for lipstick, odor stick, soap, shaving soap, foundation, and beauty cosmetics. In the cleaning agent, polyethylene glycol derivatives are also used as suspenders and thickeners. In the pharmaceutical industry, it is used as a matrix of ointment, emulsion, ointment, washing, and suppository.
