Poly(ethylene Glycol)丨CAS 25322-68-3

Pharmaceutical Industry
Poly(ethylene glycol)丨25322-68-3 (PEG) is extensively used in the pharmaceutical industry, both as an excipient and an active ingredient. It serves as a solvent, plasticizer, emulsifier, and stabilizer in drug formulations. PEG is commonly found in oral, injectable, and topical medications, including laxatives, ointments, and injectable formulations. It also plays a role in drug delivery systems, where it helps extend the circulation time of drugs in the body (via PEGylation) and improves their solubility.

Cosmetics and Personal Care
In cosmetics, PEG is used for its moisturizing and emulsifying properties. It is found in a wide range of skincare products, shampoos, conditioners, lotions, and creams. PEG acts as a humectant to retain moisture and helps in the smooth application of cosmetic products. Its versatility makes it suitable for various formulations, including those for sensitive skin.

Food Industry
Poly(ethylene glycol)丨25322-68-3 is used as a food additive, often serving as an emulsifier or stabilizer in processed food products. It is also included in coatings for certain food products to improve texture and shelf-life. PEG is considered safe for consumption in regulated amounts, and it is often used in products like ice cream and food glazes.

Industrial and Manufacturing Applications
In industrial applications, PEG is used as a lubricant, surfactant, and antifoaming agent. It is applied in various processes, such as in the production of textiles, coatings, and paints. PEG is also a key component in the manufacture of certain polymers, providing flexibility and improving mechanical properties.

Biotechnology and Medical Research
PEG plays a significant role in biotechnology research. It is often used in drug delivery systems, such as liposomes and micelles, where it helps encapsulate therapeutic agents and prolong their half-life in circulation. PEG is also used in the purification of proteins and enzymes, and in gene therapy, where it facilitates the transport of genetic material into cells.

Water-Solubility and Non-Toxicity
Poly(ethylene glycol)丨25322-68-3 is highly water-soluble, making it useful in various aqueous formulations. PEG is also generally considered non-toxic, biocompatible, and non-irritating, which contributes to its broad use in pharmaceuticals, personal care products, and medical devices.

Improved Drug Delivery
In drug delivery, PEGylation (the process of attaching PEG molecules to a drug or therapeutic agent) improves the pharmacokinetics of drugs by enhancing their stability, solubility, and bioavailability. This is particularly beneficial for biologics and protein-based drugs, helping to extend their circulation time and reduce immune responses.

Moisturizing and Emulsifying Properties
PEG acts as a humectant, which means it helps retain moisture in cosmetic products, keeping the skin hydrated. Its emulsifying properties also make it effective in stabilizing formulations, ensuring that oil and water components do not separate.

Versatility in Formulations
PEG's wide range of molecular weights allows for various applications, from low-molecular-weight PEGs used as solvents to high-molecular-weight PEGs used as thickeners and gelling agents. This versatility makes it an essential ingredient across many industries.

Lubrication and Anti-Friction
In industrial applications, PEG provides lubrication and anti-friction benefits. It is used in the production of lubricants, coatings, and cutting fluids to reduce wear and tear on machinery, improve performance, and extend equipment lifespan.

Enhanced Stability and Shelf Life
In both pharmaceuticals and food products, PEG helps improve the stability and shelf life of formulations. It prevents the crystallization of ingredients and helps preserve product consistency over time.

Poly(ethylene glycol)丨25322-68-3 is a versatile compound with a wide array of applications across pharmaceuticals, cosmetics, food, and industrial manufacturing. Its properties such as water-solubility, biocompatibility, and ability to improve drug delivery make it a valuable compound in medical research and therapeutic formulations. Whether used in cosmetics, food, or industrial processes, PEG continues to play a key role in enhancing the performance and stability of a broad range of products.
