CAS Number: 25322-68-3
PEG-12 is a polymer of ethylene oxide.
PEG-12 belongs to the group of polyoxyethylene glycols (PEG with an average molecular weight of 600).
PEG-12 is available as a high viscosity liquid or a soft white paste.
PEG-12 is characterized by a wide range of application properties.
PEG-12 has excellent softening, lubricating, solubilizing and moisturizing properties, as well as good antielectrostatic effect and strong hygroscopic properties.
In cosmetic formulations PEG-12 acts as a solubilizer and a humectant, binding water.
PEG-12 can be effectively used to modify the rheology of active substances.
Thanks to antielectrostatic properties, PEG-12 is used in industrial cleaning and metalworking.
Hygroscopic properties are used in the agrochemical industry, especially in the production of fertilizers.
PEG-12 is also a raw material for the production of esters in the chemical industry.
The product is successfully used for hardening concrete and cement mortars.
Reduces water loss in the mix, ensuring stronger bonding of the material.
With appropriate dosing, PEG-12 increases the mechanical strength of the hardened concrete.
PEG-12 can be used in the self-curing concrete.
In addition, PEG-12 has a positive effect on the mechanical properties of polyurethane foams.
With appropriate dosing to the system, PEG-12 reduces brittleness and increases the compressive strength of foams.
In addition, PEG-12 has a positive opinion from the FDA (Food and Drug Agency) which allows the use of polyethylene glycol in the form of a non-direct food additive based on CFR 21: 175.105, 175.210, 176.180, 176.200.
PEG-12 should be remembered that PEG-12 must be used in accordance with the definitions provided by the organization, not exceeding the maximum permitted dose.
PEG-12 is a mixture of polydimethylsiloxane and polyethylene/polypropylene-oxide copolymer with a conditioner that can be easily dissolved in water.
PEG-12 provides a rich column in hair columns.

Features of PEG12:
Maleimide-activated for efficient PEGylation of sulfhydryl groups at pH 6.5-7.5.
Reaction of maleimide group results in formation of stable, irreversible thioether bonds
Fully characterized PEGylation reagents with defined PEG chain lengths.
Molecules of discrete molecular weight for consistency of performance in protein-modification applications.
Provided with 12 ethylene glycol units, enabling modification procedures to be optimized for a specific application while retaining all the benefits associated with protein PEGylation.
PEG spacer provides unique advantages, including increased stability, reduced tendency toward aggregation and reduced immunogenicity.
Easy-to-follow instructions increase the likelihood of a successful outcome.
