Ko te Methylisothiazolinone (MIT, MI rānei) me te Methylchloroisothiazolinone (CMIT, CMI rānei) he matū tiaki e rua nō te whānau matū e kiia nei ko te isothiazolinones, e whakamahia ana i roto i ētahi hua whakapaipai me ētahi atu hua whare. Ka taea te whakamahi takitahi i te MIT hei āwhina i te tiaki i te hua, ka taea rānei te whakamahi tahi me te CMIT hei ranunga. He mea nui ngā matū tiaki i roto i ngā hua whakapaipai, hei tiaki i ngā hua, me te kaihoko hoki, mai i te poke o ngā moroiti i te wā e rongoatia ana me te whakamahi tonu.
Ko MIT me CMIT ētahi o ngā mea tiaki 'whānui' he iti noa iho te maha, arā, he whai hua ki te whawhai ki ngā momo huakita, rewena me ngā pokepokea ai, puta noa i te whānuitanga o ngā momo hua. Kua whakaaetia pai a MIT me CMIT kia whakamahia hei mea tiaki mō ngā tau maha i raro i te ture whakapaipai pakari a Ūropi. Ko te kaupapa matua o ēnei ture ko te tiaki i te haumaru o te tangata. Ko tētahi o ngā huarahi e mahia ai tēnei ko te aukati i ētahi kai me te whakahaere i ētahi atu mā te whakawhāiti i tō rātou kukū, te whakawhāiti rānei i a rātou ki ētahi momo hua. Ka taea anake te whakamahi i ngā mea tiaki mēnā kua whakarārangihia motuhaketia i roto i te ture.
Ko tēnei hua he otinga waiora o te ranunga kua whakahuatia ake nei. He kanapa te āhua, ā, he noa te kakara. Ko tōna mātotoru whanaunga ko (20/4℃)1.19, ko te matotoru ko (23℃)5.0mPa·s, ko te ira tio-18~21.5℃, pH 3.5~5.0. He ngāwari te wairewa ki te wai. Ko te āhua pH pai rawa atu mō te whakamahi i te waipiro waro-iti me te ethanediol ko 4~8. Ina neke atu i te 8 te pH, ka heke tōna pumau. Ka taea te penapena mō te tau i raro i te pāmahana noa. I raro i te 50℃, ka paku heke te kaha ina rongoatia mō te 6 marama. Ka tino heke te kaha i raro i te pāmahana teitei. Ka taea te hototahi ki ngā momo emulsifiers ionic me te pūmua.
