Salicylic acid ke eng?
Salicylic acid ke semela sa makhapetla a moluoane, hape ke anti-inflammatory ea tlhaho.
Salicylic acid e sebelisoa hangata ho phekola mafu a sa foleng a letlalo ho dermatology,joalo ka maqoqomete a makhopho (acne), seboko le tse ling.
Salicylic acid e ka tlosa horny, sterilization, anti-inflammatory, e loketseng haholobakeng sa phekolo ea li-acne tse bakoang ke li-clogs, lihlahisoa tsa machaba tse tloaelehileng tsa mahlaseli lisalicylic acid, mahloriso hangata ke 0.5 ho 2%.
Mosebetsi oa salicylic acid
Salicylic acid e ka sebelisoa e le lisebelisoa tse tala tsa meriana. Ho etsa aspirin, sodium salicylate, salicylamide, analgesic, phenyl salicylate le tse ling. Indasteri ea dae bakeng saho lokisetsa moxibustion bosehla bo hloekileng, bosootho bo tobileng 3GN, acid chrome yellow joalo-joalo.E boetse e sebelisoa e le sethibelo sa rabara vulcanization le li-preservatives tse thibelang likokoana-hloko
