Ingabe i-hydroxypropyl cellulose inobuthi?

I-Hydroxypropyl cellulose (HPC) iyi-polymer engenabuthi, ebolayo, futhi encibilika emanzini etholakala ku-cellulose. Isetshenziswa emikhiqizweni eyahlukene, okuhlanganisa imithi, izimonyo, ukudla, kanye nemikhiqizo yezimboni. I-HPC ngokuvamile ibhekwa njengephephile ukuthi isetshenziswe abantu futhi igunyazwe ukusetshenziswa ekudleni nasemikhiqizweni yezimonyo yi-US Food and Drug Administration (FDA).

I-HPC yinto engenabuthi, engacasuli, futhi engeyona i-allergenic. Ayibhekwa njenge-carcinogen, i-mutagen, noma i-teratogen, futhi ayibangeli noma yimiphi imiphumela emibi kubantu noma ezilwaneni uma isetshenziswe ngokuhambisana nomthamo onconywayo. I-HPC nayo akwaziwa ukuthi iwubuthi bokuzala noma obukhulayo.

Ngaphezu kwalokho, i-HPC akwaziwa njengengozi yemvelo. Ayibhekwa njengephikelelayo, i-bioaccumulative, noma i-toxic (PBT) noma iphikelela kakhulu futhi i-bioaccumulative kakhulu (vPvB). I-HPC futhi ayifakwanga ohlwini njengento eyingozi noma engcolisayo ngaphansi koMthetho Womoya Ohlanzekile noma uMthetho Wamanzi Ahlanzekile.

I-HPC isetshenziswa njenge-thickener, emulsifier, kanye ne-stabilizer ekwenziweni kwezimonyo njengama-shampoos, ama-conditioner, nama-lotions.

Naphezu kwemvelo yayo engenabo ubuthi, i-HPC kusafanele iphathwe ngokucophelela. Ukungena kwenani elikhulu le-HPC kungase kubangele ukucasuka kwamathumbu, isicanucanu, ukuhlanza, kanye nesifo sohudo. Ukuhogela uthuli lwe-HPC kungase kubangele ukucasuka kwekhala, umphimbo, namaphaphu. Ukuthintana kwamehlo ne-HPC kungase kubangele ukucasuka nokuba bomvu.

Sengiphetha, i-hydroxypropyl cellulose ngokuvamile ithathwa njengephephile ukuthi isetshenziswe abantu futhi igunyazwe ukusetshenziswa emikhiqizweni yokudla yi-FDA. Ayibhekwa njenge-carcinogen, i-mutagen, noma i-teratogen, futhi ayibangeli noma yimiphi imiphumela emibi kubantu noma ezilwaneni uma isetshenziswe ngokuhambisana nomthamo onconywayo. I-HPC futhi akwaziwa njengengozi yemvelo futhi ayifakwanga ohlwini lwezinto eziyingozi noma ukungcola ngaphansi koMthetho Womoya Ohlanzekile noma uMthetho Wamanzi Ahlanzekile. Nokho, ukungenwa inani elikhulu le-HPC kungase kubangele ukucasuka kwamathumbu, isicanucanu, ukuhlanza, nesifo sohudo, kuyilapho ukuhogela uthuli lwe-HPC kungase kubangele ukucasuka kwekhala, umphimbo, namaphaphu. Ukuthintana kwamehlo ne-HPC kungase kubangele ukucasuka nokuba bomvu.
