Product Name: PEG 400
Polyethylene glycol 400
Poly(ethylene glycol))
CAS: 25322-68-3
Chemical formula: N/A
Appearance
This product is white granular. Soluble in water, soluble in some organic solvents. The solution has high viscosity at low concentration, and can be processed by rolling, extrusion, casting, etc. It is a thermoplastic resin with good compatibility with other resins. It is resistant to bacterial attack and has weak hygroscopicity in the atmosphere.
Preparation
Ethylene oxide is prepared by autopolymerization of aluminum isopropyl alcohol.
Use
Polyoxyethylene resin is a high molecular weight homopolymer prepared by polyphase catalytic ring-opening polymerization of ethylene oxide. It can usually be distinguished into relative molecular mass of more than 2× 104 and tens of thousands of more, the former is called polyethylene glycol, the latter is called polyoxide ethylene. Polyoxide ethylene has flocculation, thickening, slow release, lubrication, dispersion, retention, water retention and other properties, suitable for medicine, fertilizer, paper, ceramics, detergents, cosmetics, heat treatment, water treatment, fire protection, oil mining and other industries, the product is non-toxic and non-irritating, will not remain in the product production process, deposition or breeding volatiles. As a papermaking additive, it can improve the retention rate of fillers and fine fibers, and is especially suitable for long fibers as a dispersant, which can shorten the beating time.
Security
It has little irritation to the skin and eyes, is difficult to be absorbed by the gastrointestinal tract when taken orally, and has very low toxicity. An aqueous solution of 5% (by mass) polyoxyethylene injected into the rabbit's eyes caused only minor burning. Polyoxyethylene had little effect on the death rate of fish, crabs, anemones, shrimp or algae. Its resin and aqueous solution are low toxic and very safe to use and handle. The U.S. Food and Drug Administration (FDA) has approved polyoxyethylene aqueous solution resins for use in specialized food packaging and as direct additives to beer.

Personal Protection
Eye/Face Protection: Use safety glasses (with side shields). Safety glasses (with side shields)
should be consistent with EN 166 or equivalent.
Skin Protection: When prolonged or frequently repeated contact could occur, use protective clothing
chemically resistant to this material. Selection of specific items such as faceshield, boots, apron, or
full-body suit will depend on the task.
Hand protection: Use gloves chemically resistant to this material when prolonged or
frequently repeated contact could occur. Use chemical resistant gloves classified under
Standard EN374: Protective gloves against chemicals and micro-organisms. Examples of
preferred glove barrier materials include: Butyl rubber. Ethyl vinyl alcohol laminate ("EVAL").
Examples of acceptable glove barrier materials include: Natural rubber ("latex"). Neoprene.
Nitrile/butadiene rubber ("nitrile" or "NBR"). Polyvinyl chloride ("PVC" or "vinyl"). Viton. When
prolonged or frequently repeated contact may occur, a glove with a protection class of 4 or
higher (breakthrough time greater than 120 minutes according to EN 374) is recommended.
When only brief contact is expected, a glove with a protection class of 1 or higher
(breakthrough time greater than 10 minutes according to EN 374) is recommended. NOTICE:Product Name: PEG 400
The selection of a specific glove for a particular application and duration of use in a workplace
should also take into account all relevant workplace factors such as, but not limited to: Other
chemicals which may be handled, physical requirements (cut/puncture protection, dexterity,
thermal protection), potential body reactions to glove materials, as well as the
instructions/specifications provided by the glove supplier.
Respiratory Protection: Respiratory protection should be worn when there is a potential to exceed
the exposure limit requirements or guidelines. If there are no applicable exposure limit requirements
or guidelines, wear respiratory protection when adverse effects, such as respiratory irritation or
discomfort have been experienced, or where indicated by your risk assessment process. For most
conditions no respiratory protection should be needed; however, if discomfort is experienced, use an
