Daim ntawv thov
Carbomer yog ib qho tseem ceeb thickener. Nws yog lub siab polymer crosslinked los ntawm acrylic acid los yog acrylate thiab allyl ether. Nws cov khoom muaj xws li polyacrylic acid (homopolymer) thiab acrylic acid / C10-30 alkyl acrylate (copolymer). Raws li cov dej-soluble rheological modifier, nws muaj cov thickening thiab ncua kev kawm ntawv, thiab yog dav siv nyob rau hauv coatings, textiles, kws, kev tsim kho, detergents thiab tshuaj pleev ib ce.
Carbomer yog ib tug nanoscale acrylic acid resin, o nrog dej, ntxiv ib me me ntawm cov sib tov (xws li triethanolamine, sodium hydroxide), tsim ntawm siab pob tshab coagulation, Carbomer txawv qauv sawv cev ntawm txawv viscosity, luv rheological los yog ntev rheological hais.
Uni-Carbomer 934P ua tau raws li tam sim no ib tsab ntawm cov nram qab no monographs:
United States Pharmacopeia/National Formulary (USP/NF) monograph rau Carbomer B
Japanese Pharmaceutical Excipients (JPE) monograph rau Carboxyvinyl Polymer
European Pharmacopeia (Ph. Eur.) monograph rau Carbomer
Suav Pharmacopoeia (PhC.) monograph rau Carbomer Hom B
Uni-Carbomer 934P yog ib qho crosslinked acrylic polymer uas yog dej-soluble rheological thickener nrog luv rheology (tsis muaj trickle).Uni-Carbomer 934P yog ib tug niaj hnub tshuaj siab viscosity thickening neeg sawv cev, muaj zoo heev stability nyob rau hauv siab viscosity, muaj peev xwm tsim ib tug tuab formulation. , carbomer 934P pob tshab tsis siab. Thiab yog dav siv nyob rau hauv opaque gels, cream thiab emulsions.
Kev ua tau zoo thiab cov txiaj ntsig:
1. luv rheological zog
2. Ua kom tuab tuab
3. Yooj yim rau diffuse
Daim ntawv thov teb:
1. Opaque gel
2. Opaque cream thiab lotions
3. tsuaj zawv plaub hau thiab ntxuav lub cev
4. tshuaj txhuam hniav
Tswv yim
1. Kev pom zoo siv yog 0.2-1.0wt %
2. Tshaj tawm cov polymer sib npaug hauv qhov nruab nrab thaum nplawm, tab sis tsis txhob agglomeration. Do kom txaus kom disperse nws
3. Kev kub ceev shearing los yog nplawm yuav tsum tau zam tom qab neutralization kom txo viscosity poob
