ʻO kēia huahana he 55% DMDMH aqueous solution, me ka hoʻohana ʻana i ka ʻōnaehana hana honua hou a me ka ʻenehana. Hoʻomalu paʻa ʻia e nā limahana ʻenehana kiʻekiʻe o ke kikowaena R&D, hilinaʻi ka maikaʻi, maikaʻi ka hoʻohālikelike ʻana, a lōʻihi ka hopena me ka ʻole o ka hopena o ka huahana. He palekana a ʻaʻole ʻona. Hiki ke hoʻohana ʻia ma kahi ākea o PH=5-12. ʻO ka holoi ʻana, emulsion He mea antiseptic a me antibacterial kūpono no nā mea hoʻonaninani e like me, cream, etc. | ||||||||||||||||||||||
| ʻano ʻano | ʻO ka fungicide kiʻekiʻe, haʻahaʻa kumu kūʻai, maʻalahi e hoʻohana, hiki ke hoʻoheheʻe ʻia i ka wai a me nā ʻawaʻawa haʻahaʻa, a paʻa i ka wai a me ka ʻaila emulsions. He kūpono ia me ka cationic, anionic a me ka nonionic surfactants, emulsifiers a me nā protein. Paʻa ia i ka manawa, ka pH ākea a me ka pae wela. | ||||||||||||||||||||||
| Hoʻohana ʻia | Ma muli o kona hoʻoheheʻe wai kū hoʻokahi, hiki ke hoʻohui ʻia ʻo DMDMH i nā creams a me ka holoi ʻana i nā hoʻonohonoho mālama pilikino me ka manaʻo o 0.2 ~ 0.6%. Inā hoʻohui ʻia ʻo DMDMH i ka surfactant, ʻo kona mahana maʻamau ʻo 50 ℃ ~ 60 ℃, a ʻo ka pH aia ma ka laulā o 7.5 ~ 8.5. No ka mea, ʻokoʻa loa nā mea hoʻohui a me nā ʻano o nā huahana mālama pilikino, hiki ke hoʻopilikia i ka maikaʻi o nā preservatives, manaʻo ikaika mākou e hōʻoia i ka pono a me ka paʻa o DMDMH ma mua o ka hana ʻana. |
