Methylisothiazolinone (MIT lossis MI) thiab Methylchloroisothiazolinone (CMIT lossis CMI) yog ob hom tshuaj preservatives los ntawm tsev neeg ntawm cov tshuaj hu ua isothiazolinones, siv rau hauv qee cov khoom siv pleev ib ce thiab lwm yam khoom siv hauv tsev. MIT tuaj yeem siv ib leeg los pab khaws cov khoom lossis nws tuaj yeem siv ua ke nrog CMIT ua ke. Cov tshuaj preservatives yog ib qho tseem ceeb hauv cov khoom siv pleev ib ce, tiv thaiv cov khoom, thiab yog li ntawd tus neeg siv khoom, tiv thaiv kev kis kab mob los ntawm cov kab mob thaum lub sijhawm khaws cia thiab siv txuas ntxiv.
MIT thiab CMIT yog ob qho ntawm cov tshuaj preservatives 'broad spectrum' tsawg heev, uas txhais tau tias lawv ua haujlwm tau zoo tiv thaiv ntau yam kab mob, poov xab thiab pwm, hla ntau hom khoom. MIT thiab CMIT tau txais kev pom zoo zoo rau kev siv ua cov tshuaj preservatives tau ntau xyoo raws li txoj cai lij choj European cosmetic nruj. Lub hom phiaj tseem ceeb ntawm cov kev cai lij choj no yog los tiv thaiv kev nyab xeeb ntawm tib neeg. Ib txoj hauv kev uas nws ua qhov no yog los ntawm kev txwv qee cov khoom xyaw thiab tswj lwm tus los ntawm kev txwv lawv qhov kev sib xyaw lossis txwv lawv rau cov khoom tshwj xeeb. Cov tshuaj preservatives tsuas yog siv tau yog tias lawv tau teev tseg tshwj xeeb hauv txoj cai lij choj.
Cov khoom no yog cov kua hydrotropic ntawm cov khoom sib xyaw saum toj no. Nws qhov tsos yog lub teeb amber thiab tsw yog ib txwm muaj. Nws qhov ceev sib piv yog (20/4 ℃) 1.19, viscosity yog (23 ℃) 5.0 mPa · s, khov point -18 ~ 21.5 ℃, pH 3.5 ~ 5.0. Nws yooj yim yaj hauv dej. Qhov pH zoo tshaj plaws rau kev siv cov cawv qis-carbon thiab ethanediol yog 4 ~ 8. Thaum pH> 8, nws qhov ruaj khov poob qis. Nws tuaj yeem khaws cia rau ib xyoos hauv qhov kub ib txwm. Hauv qab 50 ℃, kev ua haujlwm poob qis me ntsis thaum khaws cia rau 6 lub hlis. Kev ua haujlwm yuav poob qis heev hauv qhov kub siab. Nws tuaj yeem sib xws nrog ntau yam ionic emulsifiers thiab protein.

Kev Khaws Cia
nyob rau hauv qhov ntxoov ntxoo, qhuav, thiab kaw, hluav taws kev tiv thaiv.
Cov khoom no feem ntau yog siv rau hauv kev kho kom zoo nkauj, ua npuas dej da dej, surfactant thiab tshuaj pleev ib ce ua antiseptic. Tsis tuaj yeem siv rau cov khoom uas yuav kov cov ntaub so ntswg ncaj qha.
