"Polyethylene glycols (PEG)", which are obtained from condensed ethylene oxide and seafood and have various derivatives and functions, are mostly used as penetration enhancers in the topical dermatological field, since they are hydrophilic. PEGs are used as surfactants, emulsifiers, cleansing agents, skin softeners, moisturizers in cosmetic products.
Polyethylene glycols (PEG) are composed of polyether compounds that repeat ethylene glycol units according to the constituent monomer or parent molecule. Most Polyethylene glycol (PEG) is commercially available as mixtures of different oligomer sizes in wide or narrow molecular weight (MW) ranges.
Smaller molecular weight Polyethylene glycols (PEG) can be obtained in different ways:
- Catalyzed by acidic and basic catalysts
- By chemical reaction between ethylene oxide and water or ethylene glycol
It has been concluded that the use of polyethylene glycols (PEG) in cosmetics is safe when they are formulated with cocaine and related ingredients in non-irritating concentrations.
As the amount of ethylene oxide in the content of polyethylene glycols (PEG) decreases, it is more easily absorbed in the human skin. It is used in cosmetic products and personal care products, especially for purposes such as solvent, softener and moisture carrier.
