PEG oo leh miisaan molecular oo kala duwan waxay leedahay noocyo kala duwan oo qaab jireed ah. Muuqaalku wuxuu isbeddelaa marka miisaanka molecular uu ka yimaado dareere qaro weyn (Mn=200~700), mid nus-adag oo wax leh (Mn=1000~2000) una gudbo mid adag oo wax leh (Mn=3000~20000).

Qoraallo
1) dhammaan xogta farsamo ee kor ku xusan waa kuwo loogu talagalay tixraacaaga.
2) qeexitaan kale ayaa lagu soo dhaweynayaa si looga wada hadlo.
Maareynta
Gacan ku qabashada waxaa lagu sameeyaa meel hawo fiican leh. Xiro qalab ilaalin oo ku habboon. Ka hortag kala firdhinta boodhka. Si fiican u dhaq gacmaha iyo wejiga ka dib markaad taabato.
Taxaddarro si ammaan ah loogu maareeyo. Ka fogow taabashada maqaarka iyo indhaha. Ka fogow soo saarista boor iyo aerosols. Bixi hawo-qaadis ku habboon meelaha ay ka sameysmaan boorka.
Kaydinta
Ku kaydi meel qabow. Weelka si adag ugu xidh meel qalalan oo hawo fiican leh. Heerkulka kaydinta ee lagu taliyay waa 2 – 8 °C
Macluumaadka gaadiidka
Looma nidaamiyo sidii walxo khatar ah.
