What are Great about Sanyo Chemical's Polyethylene Glycol "PEG"
1
Water-soluble polymers with a wide range of applications
PEG is highly water soluble and is not hydrolyzed, so it is widely used as a water soluble base for viscosity adjustment and other applications.
The solubility of PEG in water is not affected by the presence of electrolytes. It is soluble in hard water and aqueous solutions of salts, as well as acids and alkalis (except for extremely concentrated acids and alkalis).
2
A wide range of molecular weight products are lined up to provide a variety of functions
Polyethylene glycol (PEG) can provide various functions depending on its molecular weight, such as smoothing, lubrication, thickening/thickening, plasticization, emulsification/dispersion, heat storage, moisture retention, binding, and antistatic.
For example, PEG with high molecular weight is used as a water-soluble binder, PEG with low molecular weight is used as a plasticizer, and PEG is also used as a dispersant, lubricant, heat medium, sensitizer, dust-proofing agent, etc., to express functions suitable for a variety of applications.
(For details, please refer to "Major Applications" and "Relationship between Molecular Weight and Applications" below.)
3
Active as a raw material for many chemical products
Both ends of polyethylene glycol (PEG) are primary alcohols, making it easy to esterify and etherify.
In addition to surfactants, PEG is used as a raw material for numerous chemical products, not limited to polyesters and polyurethanes.
4
Highly Safe
Polyethylene glycol (PEG) is a highly safe compound with low irritation and toxicity.
(Polyethylene glycol for the pharmaceutical industry is separately lined up as "MACROGOL" in the Japanese Pharmacopoeia.
Our "MACROGOL" is a pharmaceutical product for manufacturing only. If you need samples for testing and research or the local formulation, please contact the reagent manufacturer or the local formulation manufacturer).

Binders
PEG-4000S, PEG-6000S, and other PEGs with large molecular weights have a high binder effect and are water soluble, so they can be used as binders for solid face powders and enzymes for detergents.
Anti-caking agent for powedered detergents
PEG-6000S can be used as an anti-caking agent for powdered detergents.
Anti-cracking agent
PEG-6000S can be used as an anti-cracking agent for solid soap.
Anti-clogging agent for liquid detergent
When PEG-200 or PEG-300 is added to liquid detergents such as kitchen detergents, it acts as an anti-clogging agent for liquid detergent containers.
Dust Preventive Agent
PEG-6000S can be used as a dust inhibitor for powder products such as powder cosmetics and powder detergents.
3
Textile
Antistatic Agent
PEG-2000, PEG-4000S, and PEG-6000S can be used as antistatic agents for polyester fibers.
Dyeability modifier
Copolymerization with PEG-1000 and PEG-2000 produces polyester with excellent dyeability.
Glue agent
When polyester, nylon, rayon, and other fabrics are glued and sewn, the glue sometimes sticks to the needle and interferes with the sewing process. It is also effective in preventing the glue from sticking to the fabric.
Punching agent
PEG-400, PEG-600, and PEG-1000 can be used as drilling agents for hollow and porous fibers.
4
Paper Manufacturing
Paper Softeners
Polyethylene glycol (PEG) is suitable as a paper softener and its low volatility ensures a long-lasting softening effect; PEG-200, PEG-300, and PEG-400 are especially suitable as softeners for PVA films and cellophane.
Lubricants
PEG-1540 and PEG-4000S can be blended with starch or protein glue and used as lubricants in calenders in the papermaking process.

9
Wood
Crack Preventive Agent
When wood is soaked in an aqueous solution of PEG-600 or PEG-1000, the moisture in the wood is replaced by polyethylene glycol, resulting in smaller dimensional changes and less susceptibility to cracking. In addition, for preservation, deformation of the buried cultural properties can be prevented. deformation of wooden artifacts in archeological sites can be prevented if the moisture is replaced with PEG 4000S for preservation.

Various surfactants can be synthesized using the hydroxyl groups at both ends of polyethylene glycol (PEG). Among them, esterified products with higher fatty acids are typical surfactants used as emulsifiers, dispersants, and detergents.
Raw materials for chemical products
The hydroxyl groups at both ends of PEG are modified (alkyl etherification, amination, carboxylation, glycidyl etherification, esterification, etc.) and used as raw materials for chemical products.
12
Other
Viscosity Regulators
Using PEG-600 or PEG-1000 as a viscosity adjuster for ballpoint pen inks improves ink performance.
Thermal media
PEG-400 and PEG-600 have high boiling point and specific heat and good thermal stability, so they can be used as heat transfer media. They are also easily soluble in water, making them easy to clean.
Sensitizers
PEG-400 can be mixed with saturated aliphatic polyhydric alcohols, etc. and used as a sensitizer to improve the sensitivity and contrast of photosensitive films.
Thermal storage agent
Polyethylene glycol (PEG) is suitable as a heat storage agent because of its high heat of fusion.
Cold storage agent
PEG-200 is water soluble and has a low freezing point, so it can be used as a base agent for cold insulators.
