Waa maxay salicylic acid?
Salicylic acid waa laga soosaaray jilif safsaafka ah ee dhirta, iyo sidoo kale ka hortagga bararka dabiiciga ah.
Salicylic acid caadi ahaan loo isticmaalo daaweynta cudurrada maqaarka ee kala duwan ee maqaarka ee maqaarka,sida finan (finan), gooryaanka iyo wixii la mid ah.
Salicylic acid waxay ka saari kartaa geesaha, sterilization, anti-bararka, taas oo aad ugu habboondaawaynta finanka ay keento xinjirowga, waxyaabaha finan ee caadiga ah ee caalamiga ah waasalicylic acid, fiirsashada inta badan waa 0.5 ilaa 2%.
Shaqada salicylic acid
Salicylic acid waxaa loo isticmaali karaa sidii alaabta ceeriin ee dawooyinka. Diyaarinta aspirin, sodium salicylate, salicylamide, analgesic, phenyl salicylate, iyo kuwa kale. Warshadaha dheeha loogu talagalaydiyaarinta moxibustion jaalaha saafi ah, brown toos ah 3GN, jaalaha chrome acid iyo wixii la mid ah.Waxa kale oo loo isticmaalaa dib-u-dhige vulcanization caag ah iyo jeermiska jeermiska ilaaliya
