He pai ake te whai huatanga o te pāhare pākawa waro, he tote waikawa formic, i ētahi atu kai tango hukapapa pēnei i:

• pāhare pākawa ātete
• Urea
• Kariserō

Ki te whakatauritea ki te pāhare pākawa waro, e tangohia ana i te whai huatanga ōrite o te 100%, ko te whai huatanga o te pāhare pākawa waro acetate he 80 ki te 85% noa iho, i runga i te pāmahana o nāianei.

E whakataurite ana tēnei ki te whai huatanga o te urea o te 70% me te glycerol o te 45%.
