What is polyethylene oxide？

Polyethylene oxide, abbreviated PEO(poly(ethylene oxide)), is produced by ring-opening polymerization of ethylene oxide (also called ethylene oxide). It is an important water-soluble polymer material. It has a wide range of applications, including paper, electrical appliances, construction, mining, medicine, agriculture, textiles, printing, oil extraction, municipal engineering, washing and personal care products.

Characteristics of Polyethylene oxide

Polyethylene, Oxidized completely soluble in water, soluble in some organic solvents. The solution has high viscosity at low concentration. It is a soft, high strength thermoplastic resin. It can be processed by calendering, extrusion, casting, etc. Resistant to bacterial attack, will not corrupt, in the atmosphere hygroscopicity is usually not large; The high polymer has flocculation; Good compatibility with other resins.

What are the uses of Polyethylene oxide in the daily chemical field?

1. In the shampoo system, the use of high molecular weight polyoxyethylene (PEO) and cationic hydroxyethyl cellulose at the same time can provide excellent conditioning properties. Cleaning hair with a formula containing cationic hydroxyethyl cellulose and high molecular weight PEO results in a 30% improvement in wet combing compared to a formula containing only cationic hydroxyethyl cellulose. Used in combination with PEO. The adsorption capacity of cationic hydroxyethyl cellulose controlled silicone oil and octyl methoxycinnamate increased by 27% and 25%, respectively.

2. Due to the non-toxic and gelatinizing properties of PEO, it is used as one of the components of denture fixation agents, which can play a buffer role between dentures and the mouth, and also help to reduce unpleasant odor and taste.

3.PEO aqueous solution is a pseudoplastic liquid. Due to its viscosity sensitivity to shear rate, it can be used as a contact lens, that is, a contact lens solution, and bacteria are not easy to grow on PEO to maintain contact sterility.

4. The mixture containing PEO can be used as a skin cleanser (such as detergent, hand soap, etc.), which has good foam properties and is easy to be washed off, making the skin soft and smooth.

5.Polyethylene, Oxidized can also be used as a component of teeth whitening solution to obtain good teeth whitening solution. It is also used as a component of shaving cream to form a thin film on the face for non-foaming shaving.

6. The absorbent resin made of PEO after crosslinking can be used in women’s sanitary napkins and baby diapers.

What are the uses of Polyethylene oxide in medicine?

1.The aqueous solution of PEO is coated on the outer layer of the pill to make a controllable slow-release drug, which has been widely used in the pharmaceutical industry to control the diffusion rate of the pill ingredients in the body and improve the efficiency of the pill. The long chain of the PEO polymer and the water molecules it binds to act as a barrier to protect the modified drug from enzymatic degradation, rapid clearance by the kidney, or interaction with cell surface proteins, thereby reducing adverse immune effects. The range of pH and temperature stability of PEO-modified drugs is also extended relative to non-PEO-modified drugs. After PEO modification, the water solubility of polypeptide drugs increased, kidney clearance slowed down, toxicity decreased, so that its pharmacokinetics and pharmacodynamic properties were significantly improved. The study shows that the synthesis of branched polyoxyethylene and modification of cisplatin. The cytotoxicity and acute toxicity of cisplatin modified by linear PEO and dendritic PEO were compared. The half-inhibitory concentration of cisplatin modified by dendritic PEO was lower than that of linear modified products with the same molecular weight, but there was no significant difference in acute toxicity.

2. Due to the non-toxicity and high viscosity of polyethylene, oxidized (PEO) can be used as one of the components of denture fixative, which can play a buffer role between denture and mouth, and also help to reduce unpleasant odor and taste.

3. Polyethylene, Oxidized (PEO) aqueous solution is a pseudoplastic liquid that uses its viscosity as a contact lens solution due to its sensitivity to shear rate, and it is not easy for bacteria to grow on polyoxidized ethylene (PEO) to maintain contact sterilization.
