O le ā le Salicylic acid?
O le salicylic acid o se mea e maua mai i le pa'u o le la'au o le willow, ma o se vaila'au fa'alenatura fo'i e tete'e ai i le mumū.
O le salicylic acid e masani ona faʻaaogaina i le togafitia o faʻamaʻi paʻu tumau eseese i le dermatology,e pei o le mageso (acne), mamago ma isi mea faapena.
E mafai e le salicylic acid ona aveese le fulufulu, faʻamamāina, faʻaitiitia le mumū, lea e matua talafeagai lavaMo le togafitia o mageso e mafua mai i poloka, o oloa fa'avaomalo mo mageso osalicylic acid, o le malosi e masani lava ona 0.5 i le 2%.
Galuega a le Salicylic acid
E mafai ona fa'aaogaina le salicylic acid o ni mea mata mo vaila'au. Mo le sauniaina o le aspirin,sodium salicylate, salicylamide, fa'aitiitia le tiga, phenyl salicylate, ma isi. Alamanuia vali mo lesauniuniga o le moxibustion samasama mama, enaena tuusa'o 3GN, samasama acid chrome ma isi mea faapena.E faʻaaogaina foʻi o se mea e taofia ai le faʻafefeteina o le paʻu ma mea e faʻasao ai siama

Fa'aaogāina o le Salicylic acid
1. O le salicylic acid e ta'ua o le ortho hydroxy benzoic acid (o-hydroxybenzoic acid) o se ituaiga omea mata taua fa'alenatura fa'apitoa.I le gaosiga o vailaʻau faʻasaina, e faʻaaogaina mo le vailaʻau faʻasaina phosphorus faʻapitoa Isocarbophos,isofenphos methyl intermediate isopropyl salicylate ma le Rodenticide warfarin, fasioti isumu ether4-hydroxy coumarin vaeluagalemu; i le pisinisi vailaʻau, sa faʻaaogaina le salicylic acid e fai mavailaʻau faʻamaʻi, e pei foʻi o ni vailaʻau faʻafefiloi o le acetylsalicylic acid (aspirin) ma isi vailaʻau; o se vailaʻau foʻimea mata taua o vali, mea manogi, e pei o le alamanuia paʻu.
2. E masani ona faʻaaogaina o ni mea mata o le aspirin feedstock ma le vailaʻau faʻasaina o le amine ma vailaʻau faʻasaina.oloa phosphorus, e mafai foi ona faʻaaogaina i le alamanuia vali, faʻamamaina ma vailaʻau faʻamaʻi, ma isi.
3. Fa'aaogaina i le alamanuia o vaila'au mo le fa'aitiitia o le fiva, fa'aitiitia o le tiga, fa'aitiitia o le mumū,fualaau fa'aitio, vali fa'apisinisi e fa'aaogaina mo vali tuusa'o o azo ma vali fa'asusu acid, ae fa'apea fo'i mo mea manogi, ma isi.
4. Fa'aaogaina e fai ma fa'ailoga fa'afefiloi ma mea fa'asao.
5. Fa'amaoniga mo le alumini, boron, cerium, kopa, u'amea, apamemea, manganese, mercury, nickel, siliva,
titanium, tungsten, vanadium, sulfite, nitrate ma le nitrite. Fuafuaina o le alumini, kopa, u'amea,thorium, titanium ma le uranium. Metotia alkali ma le tulaga fa'atulagaina o le iodometry titration. O le fluorescentfa'ailoga. Fa'ailoga fa'apitoa.| Mea | Fa'asino Upu |
