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

He ʻokoʻa nā waiwai o ka polyethylene glycol ma muli o kona kaumaha molekala pili, mai ka wai ʻoniʻoni ʻole a me ka ʻala ʻole a hiki i nā paʻa waxy. ʻO ka poʻe me ke kaumaha molekala o 200-600 he wai ia ma ka lumi wela, aʻo ka poʻe me ke kaumaha molekala ma luna o 600 e lilo i semi-paʻa. ʻOkoʻa nō hoʻi nā waiwai me ka awelika molekala kaumaha. Mai ka wai viscous kala ʻole a ʻala ʻole a hiki i ka paʻa waxy.

Hoʻohana nui ʻia ka polyethylene glycol i nā mea hoʻonaninani a me nā ʻoihana lāʻau. Ma muli o nā waiwai maikaʻi loa o ka polyethylene glycol, e komo pū me ka wai solubility, non volatility, physiological inertness, mildness, lubricity, a me ka hiki ke hoʻomaʻemaʻe, palupalu, a hāʻawi i kahi ʻoluʻolu ma hope o ka ʻili.
