I-sodium carboxymethyl cellulose ku-toothpaste

Isingeniso

I-sodium carboxymethyl cellulose (CMC) iyisithako esisetshenziswa kakhulu ku-toothpaste. Iwuhlobo lokuphuma kwe-cellulose, okuyi-polymer yama-molecule e-glucose. I-CMC isetshenziswa emikhiqizweni eyahlukene, okuhlanganisa ukudla, imithi, kanye nezimonyo. Kumuthi wokuxubha, i-CMC isebenza njenge-ejenti ejiyayo, i-stabilizer, ne-emulsifier. Kuyasiza ukugcina umuthi wokuxubha ungahlukani futhi unikeza ukuthungwa okubushelelezi, okukhilimu. I-CMC iphinde isize ukuhlanganisa ezinye izithako ndawonye, ​​okwenza umuthi wokuxubha ube lula ukusabalalisa futhi uwunikeze impilo yeshelufu ende.

Umlando we-Sodium Carboxymethyl Cellulose ku-Toothpaste

I-sodium carboxymethyl cellulose isetshenziswe ku-toothpaste kusukela ekuqaleni kwekhulu lama-20. Yasungulwa okokuqala ngeminyaka yawo-1920 ngusosayensi waseJalimane, uDkt. Karl Ziegler. Wathola ukuthi ukwengeza i-sodium ku-cellulose kwakha uhlobo olusha lwe-polymer olwaluzinzile futhi lusebenziseka kalula kune-cellulose yendabuko. Le polymer entsha yayibizwa nge-carboxymethyl cellulose, noma i-CMC.

Ngawo-1950, i-CMC yaqala ukusetshenziswa ku-toothpaste. Itholwe iyisithako esisebenzayo sokujiya kanye nesiqinisi, futhi yasiza ukugcina umuthi wokuxubha ungahlukani. I-CMC iphinde yanikeza ukuthungwa okubushelelezi, okunokhilimu futhi yasiza ukuhlanganisa ezinye izithako, okwenza umuthi wokuxubha ube lula ukusabalaliswa futhi uwunikeze impilo yeshelufu ende.

Izinzuzo ze-Sodium Carboxymethyl Cellulose ku-Toothpaste

I-sodium carboxymethyl cellulose inezinzuzo eziningana lapho isetshenziswa ku-toothpaste. Isebenza njenge-ejenti ejiyayo, i-stabilizer, kanye ne-emulsifier, isiza ukugcina umuthi wokuxubha ukuthi ungahlukani futhi unikeze ukuthungwa okubushelelezi, okukhilimu. I-CMC iphinde isize ukuhlanganisa ezinye izithako ndawonye, ​​okwenza umuthi wokuxubha ube lula ukusabalalisa futhi uwunikeze impilo yeshelufu ende.

Ngaphezu kwalokho, i-CMC isiza ukunciphisa inani lezithako ezilumayo ku-toothpaste. Lokhu kubalulekile ngoba izithako ezilumayo zingalimaza koqweqwe lwawo lwamazinyo futhi zibangele ukuzwela. I-CMC isiza ekwehliseni ukuhuzuka komuthi wokuxubha, iwenze ube mnene emazinyweni nasezinsinini.

Ekugcineni, i-CMC isiza ukuthuthukisa ukunambitheka komuthi wokuxubha. Kuyasiza ukufihla ukunambitheka okungajabulisi namaphunga, okwenza umuthi wokuxubha ube mnandi ukuwusebenzisa.

Ukuphepha kwe-Sodium Carboxymethyl Cellulose ku-Toothpaste

I-sodium carboxymethyl cellulose ngokuvamile ibhekwa njengephephile uma isetshenziswa ku-toothpaste. Igunyazwe i-US Food and Drug Administration (FDA) ukuze isetshenziswe ekudleni, emithini yemithi, nasezimonyoni. I-CMC iphinde igunyazwe yi-American Dental Association (ADA) ukuthi isetshenziswe ku-toothpaste.

Ngaphezu kwalokho, i-CMC ayinabo ubuthi futhi ayicasuli. Ayibangeli ukusabela okubi lapho isetshenziswa ku-toothpaste.

Isiphetho

I-sodium carboxymethyl cellulose iyisithako esisetshenziswa kakhulu ku-toothpaste. Isebenza njenge-ejenti ejiyayo, i-stabilizer, kanye ne-emulsifier, isiza ukugcina umuthi wokuxubha ukuthi ungahlukani futhi unikeze ukuthungwa okubushelelezi, okukhilimu. I-CMC iphinde isize ukuhlanganisa ezinye izithako ndawonye, ​​okwenza umuthi wokuxubha ube lula ukuwusakaza futhi uwunikeze impilo yeshelufu ende. Ukwengeza, i-CMC isiza ukwehlisa inani lezithako ezilumayo emuthini wokuxubha, iwenze ube mnene emazinyweni nasezinsini. Ekugcineni, i-CMC isiza ukuthuthukisa ukunambitheka komuthi wokuxubha, ikwenze kube mnandi ukuyisebenzisa. Sekukonke, i-CMC iyisithako esiphephile nesisebenzayo kumuthi wokuxubha.
