Chii chinonzi Salicylic acid?
Salicylic acid chirimwa chewillow bark mushoma, uye zvakare echisikigo inorwisa-kuzvimba.

Salicylic acid inowanzo shandiswa pakurapa kwakasiyana siyana kusingaperi kwezvirwere zveganda mune dermatology,zvakaita semakonye (acne), honye nezvimwewo.
Salicylic acid inogona kubvisa horny, sterilization, anti-kupisa, iyo yakakodzera kwazvo yekurapa acne yakonzerwa nemablogs, epasi rose makuru acne zvigadzirwa ari salicylic acid, iko kusungwa kunowanzoita 0.5 kusvika 2%.
 
Basa reSalicylic acid
Salicylic acid inogona kuve usd semishonga mbishi zvinhu. Kugadzirira aspirin,
sodium salicylate, salicylamide, analgesic, phenyl salicylate, nezvimwe. Indasitiri yedhayi yeiyo Kugadzirira kwemoxibustion yakachena yero, yakananga brown 3GN, acid chrome yero uye zvichingodaro.Inoshandiswa zvakare seyebhubhu vulcanization retarder uye mishonga inouraya utachiona
 
Kunyorera kweSalicylic acid
1. Salicylic acid inonzi ortho hydroxy benzoic acid (o-hydroxybenzoic acid) imhando yakakosha organic yekugadzira mbishi zvinhu.Mukugadzirwa kwemushonga wezvipembenene, inoshandiswa kugadzira organic phosphorus pesticide Isocarbophos,isofenphos methyl yepakati isopropyl salicylate uye Rodenticide warfarin, kuuraya makonzo ether wepakati 4-hydroxy coumarin; muindasitiri yemishonga, salicylic acid yakashandiswa se antiseptics, zvakare seanopindirana eacetylsalicylic acid (aspirin) nemimwe mishonga; zvakare iri yakakosha mbishi zvinhu zve dhayi, zvinonhuwira, senge yerabha indasitiri.

2. Inonyanya kushandiswa sezvinhu zvakasvibirira zveasipurini feedstock uye mishonga yekuuraya zvipuka aqueous amine uye 
zvigadzirwa zvephosphorus, zvinogona zvakare kushandiswa muindasitiri yedhayi, kunatsa uye kemikari reagent, nezvimwe.

3. Inoshandiswa muindasitiri yemishonga yeantipyretic, analgesic, anti-inflammatory,
diuretic zvinodhaka, maindasitiri dhayi anoshandiswa kuendesa iwo azvo madhayi uye acid mordant madhayi, asi zvakare nezvinonhuwira, nezvimwe.

4. Inoshandiswa seyakaomarara chiratidzo uye inochengetedza.

5. Kuongorora kwealuminium, boron, cerium, mhangura, simbi, lead, manganese, mercury, nickel, sirivheri,

titanium, tungsten, vanadium, sulfite, nitrate uye nitrite. Kugadziriswa kwealuminium, mhangura, simbi,thorium, titanium uye uranium. Alkali nzira uye iodometry titration standard. Iyo fluorescent chiratidzo. Complexometric chiratidzo.
