E UIGA I LE CAB-35
Cocamidopropyl betaine mo sina taimi puupuu
O le Cocamidopropyl betaine (CAB) o se ituaiga zionic surfactant, vai samasama vaivai, o lona tulaga patino o loʻo faʻaalia i le ata o loʻo i lalo, o lona mafiafia e latalata i le vai, 1.04 g/cm3. E matua mautu lava i lalo o tulaga acidic ma alkaline, e faʻaalia ai uiga lelei ma uiga anionic, ma e masani ona faʻaaogaina faʻatasi ma surfactants leaga, cationic ma non-ionic.
Tekinolosi gaosiga o le cocamidopropyl betaine
Sa saunia le Cocamidopropyl betaine mai le suāuu popo e ala i le fa'asusuina ma le N ma le N dimethylpropylenediamine ma le quaternization ma le sodium chloroacetate (monochloroacetic acid ma le sodium carbonate). O le fua e tusa ma le 90%. O la'asaga patino o le tu'uina lea o le molar methyl cocoate tutusa ma le N, n-dimethyl-1, 3-propylenediamine i totonu o le kettle reaction, fa'aopoopo le 0.1% sodium methanol e fai ma catalyst, fa'aoso i le 100 ~ 120 ℃ mo le 4 ~ 5 itula, fa'apuna le methanol by-product, ona togafitia lea o le amide tertiary amine. Ona tu'uina lea o le amido-tertiary amine ma le sodium chloroacetate i totonu o le kettle masima, ma saunia le cocaminopropyl betaine e tusa ai ma tulaga o le fa'agasologa o le dimethyldodecyl betaine.
Meatotino ma fa'aoga o le cocamidopropyl betaine
O le CAB o se vailaʻau faʻamamā e lelei lona faʻamamāina, faʻapupuna ma faʻamalūlūina, ma e fetaui lelei ma vailaʻau faʻamamā anionic, cationic ma non-ionic. O lenei oloa e itiiti sona faʻaita, e vaivai lona faʻatinoga, e maaleale ma mautu le foam, e talafeagai mo le sampoo, gel taʻele, vailaʻau faʻamamā foliga, ma isi mea, e mafai ona faʻaleleia atili ai le vaivai o lauulu ma le paʻu. A faʻapipiʻi faʻatasi ma se aofaʻiga talafeagai o le vailaʻau faʻamamā anionic, e manino lava lona faʻamālūlūina, ma e mafai foʻi ona faʻaaogaina o se vailaʻau faʻamamā, vailaʻau faʻasusu, vailaʻau faʻamaʻi fungicide, vailaʻau faʻasaga i le siama, ma isi mea. Ona o lona faʻapupuna lelei, e faʻaaogaina lautele i le faʻaaogaina o fanua suauʻu. O lona galuega autu o le galue o se vailaʻau faʻaitiitia le viscosity, vailaʻau faʻasuʻu ma vailaʻau faʻapupuna, ma faʻaaoga atoatoa lona gaioiga i luga e faʻasusu ai, faʻasusu ma faʻamamā ai le suauʻu mata i le palapala e iai le suauʻu e faʻaleleia atili ai le saoasaoa o le toe faʻaleleia o le gaosiga e tolu.
Uiga o oloa o le cocamidopropyl betaine
1. Lelei tele le solubility ma le fetaui lelei;
2. E sili ona lelei le fa'apupula ma le fa'amālūlūina tele o le tino;
3. Faatasi ai ma le maualalo o le itaitagofie ma meatotino e faʻaumatia ai siama, o le fetaui lelei e mafai ona faʻaleleia atili ai le vaivai, faʻaleleia ma le mautu o le vevela maualalo o oloa fufulu;
4. E tete'e lelei i le vai malō, e tete'e i le vai ma e faigofie ona pala.
Fa'aaogaina o le cocamidopropyl betaine
E fa'aaogā lautele i le sauniaina o sampoo e lelei ma lelei, fufulu tino, vaila'au fa'amamā lima, vaila'au fa'amamā foam ma vaila'au fa'amamā fale; O le mea autū lea e fai ai le sauniaina o sampoo māmā mo pepe, vaila'au fa'amamā foam mo pepe ma oloa tausiga o le pa'u o pepe. O se vaila'au fa'amālūlū lelei tele i le tausiga o lauulu ma le pa'u; E mafai fo'i ona fa'aaogā e fai ma vaila'au fa'amamā, vaila'au fa'asusu, vaila'au fa'ama'a'a, vaila'au fa'amamago ma vaila'au fa'amate siama.
