What is PEG/PPG-17/6 COPOLYMER used for?

PEG/PPG-17/6 Copolymer has many uses in the world of skin care and cosmetics. Primarily, it acts as a solvent and can mix other ingredients well in a formulation to form an evenly textured product that is easier to spread and feels good on the skin. Oil-based and water-based ingredients do not separate and the product lasts a long time due to PEG/PPG-17/6 Copolymer. Further, this effective ingredient contributes to the enhanced delivery of active ingredients, improving their absorption into the skin. It is added to a range of products like foundations, lotions, serums, and sunscreens. PEG/PPG-17/6 Copolymer is also hydrating and aids in the effective cleansing of dirt, dust, and oil.


PEG/PPG-17/6 Copolymer is made through a process of copolymerization, where polyethylene glycol (PEG) and propylene glycol (PPG) are combined under controlled conditions. The copolymerization reaction results in the formation of a copolymer with repeating units of PEG and PPG, creating the PEG/PPG-17/6 Copolymer with its specific structure and properties.
