“PEGs, also known as macrogols, are compounds widely used in medicines, cosmetics and household products. They have many different uses, for example, as the surface coatings of tablets (medicines), ointment bases in creams, and as the active ingredient in some laxatives and bowel preparations.
Different types of PEG exist with different molecular weights. Research suggests allergic reactions are more serious with higher doses and with higher molecular weight PEGs.”

Thanks Alan. There is also the question re how much unincorporated PEG is in batches of ALC-0159. I might have seen someone discussing that?
