6.. Te aukati o te koriri: He pai te riri o te Hemc me te pumau o te koriri i roto i te rokiroki mo te wa roa.
7. PH Starbay: Ko te tirohanga o te otinga wai o nga hua Hemc kaore e tino pa ki te waikawa, a Alkali ranei, a ko te uara pH he pumau tonu i roto i te whānuitanga o te 3.0-11.0.
Tono: Ka taea te whakamahi i te wai hydroxyethyl hei kaihoko tiaki colloidal, emulsifier me te marara na tona mahi kaha i roto i te otinga o te papa. Ko tana tauira tono e whai ake nei: Ko te mana o te hydroxyethyl methylcelllose i runga i te mahinga o te raima. Ko te Mydroxyethyl methylcellulose he kakara, he koretake, he kore-paitini, ka taea te rewa i roto i te wai makariri hei hanga i te otinga ngawari. Kei a ia nga ahuatanga o te matotoru, te herea, te marara, te whakakii i te kiriata, te aukati, te whakakao, te makuku me te tiaki i te korowai. Mai i te mea ko te otinga ahumoana he mahi kaha te papa, ka taea te whakamahi hei kaihoko tiaki Colloidal, emulsifier me te marara. He pai te hydrophility CommercelumyLose o te hydroxyumenyllose
