Ko nga hua inamata, i roto i te wai matao ka tere marara, ka ngaro i roto i te wai, i tenei wa karekau he poiketa o te wai, no te mea kua marara noa te HPMC ki te wai, kaore he tino rewa. Tata ki te 2 meneti, ka piki haere te pokey o te wē, ka puta he colloid karekau marama. Awhe tono whanui, i roto i te paura putty me te kumete, me te kapia wai me te peita, ka taea te whakamahi, kaore he taboo.
Hua wairewa wera, i roto i te wai matao, e taea te tere marara i roto i te wai wera, ngaro i roto i te wai wera, ka taka te pāmahana ki tetahi pāmahana, pokey puta āta, tae noa ki te hanganga o te colloid kerekere marama.
