He aha ka Polyethylene Glycol CAS 25322-68-3?

He ʻokoʻa nā ʻano o ka polyethylene glycol ma muli o kona kaumaha molekala pili, mai nā wai viscous ʻaʻohe kala a me ke ʻala ʻole a hiki i nā mea paʻa waxy. ʻO nā mea me ke kaumaha molekala o 200-600 he mau wai ia ma ka mahana o ka lumi, ʻoiai ʻo nā mea me ke kaumaha molekala ma luna o 600 e lilo mālie i hapa-paʻa. ʻOkoʻa pū nā ʻano me ke kaumaha molekala awelika. Mai ka wai viscous ʻaʻohe kala a me ke ʻala ʻole a hiki i ka mea paʻa waxy.
