Aplication of the products:

1. Chemical uses
PEG is the basis of a number of laxatives. Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy.PEG is also used as an excipient in many pharmaceutical products.When attached to various protein medications, polyethylene glycol allows a slowed clearance of the carried protein from blood.
2. Medical uses
PEG is often used (as an internal calibration compound) in mass spectrometry experiments, with its characteristic fragmentation pattern allowing accurate and reproducible tuning.
PEG derivatives, such as narrow range ethoxylates, are used as surfactants.
PEG has been used as the hydrophilic block of amphiphilic block copolymers used to create some polymersomes.
3. Biological uses
PEG is commonly used as a precipitant for plasmid DNA isolation and protein crystallization. X-ray diffraction of protein crystals can reveal the atomic structure of the proteins.
PEG is used to fuse two different types of cells, most often B-cells and myelomas in order to create hybridomas.
4. Commercial uses
PEG is the basis of many skin creams (as cetomacrogol) and personal lubricants (frequently combined with glycerin).
PEG is used in a number of toothpastes as a dispersant. In this application, it binds water and helps keep xanthan gum uniformly distributed throughout the toothpaste.

Description:

PEG is the common abbreviation for polyethylene glycol – or, more properly, poly (ethylene glycol) – which refers to a chemical compound composed of repeating ethylene glycol units. PEG is which is water-soluble, non-toxic, non-antigenic, and biocompatible. Purified PEG is most defined by their molecular weight (MW) ranges.

For example, PEG600 is PEG polymer with MW of 600.

PEG 10K or PEG 10,000 denotes a mixture of PEG molecules (about 195-265 PEG molecules) having an average MW of 10,000 g/mol.

PEG has several chemical properties that make it especially useful in various biological, chemical and pharmaceutical settings:

• Non-toxic and non-immunogenic – can be added to media and attached to surfaces and conjugated to molecules without interfering with cellular functions or target immunogenicities
• Hydrophilic (aqueous-soluble) – attachment to proteins and other biomolecules decreases aggregation and increases solubility
• Highly flexible – provides for surface treatment or bioconjugation without steric hindrance

Application: Be used in pharmaceuticals, cosmetics, chemical engineering, rubber, metal finishing, pesticide, pigment and spinning & weaving fields. It is also one of the main materials of ester type surface active agent.
Packaging:
PEG200-1000: Iron or plastic barrel. Net weight 50Kg, 200Kg.
PEG2000-8000: Plastic woven bag lined with plastic bag or compound bag. Net weight 25kg.
Storage: This product does not belong to dangerous chemicals. Store in a cool, dry, ventilated place. Avoid moisture, direct sunlight and collision. Handle with care.
PEG-200 can be used as the medium of organic synthesis and have a higher heat carrier requirements in the chemical industry as a daily moisturizer, salt solubilizer, viscosity modifiers; in the textile industry as a softener, antistatic agent; and pesticides in the papermaking industry as a wetting agent.
PEG-400, PEG-600, PEG-800 matrix for pharmaceutical and cosmetics, rubber industry and textile industry lubricants and wetting agents. PEG-600 in the metal industry in the electrolyte can be added to enhance the ground effect and enhance the luster of metal surfaces

Solutions requiring PEG and 190 Proof Alcohol
Step 1. Prepare a hot water bath. Boil water in microwave or on a pot. Once boiling starts remove from heat.
Step 2. Place PEG and powder in beaker.
Step 3. Place the beaker deep enough in to the water so that the hot water is level with the PEG and powder. Gently swirl or stir with a stir rod until solution is clear. Reheat water as needed.
Step 4. Allow PEG to cool some. Then add in your 190 proof alcohol. You don't have to do this drop by drop but don't just dump it in. Pour it in slowly.
Step 5. Stir or gently shake until mixed.

For recipes that do not require PEG.
Mix powder and 190 proof alcohol.
Stir with stir rod or shake. Most powders that do not require PEG will disolve no problem. If heat is needed follow the instructions for heating powders that use PEG. Reply With Quote
