SALICYLIC ACID MOLAR MASS SKIN
In the pharmaceutical industry, it is used as a skin care agent.
In the food industry, it is used as a food additive and flavoring agent. In the textile industry, glycolic acid is used as a dyeing agent and as a tanning agent.
It is also hygroscopic (it can absorb water vapor when exposed to air). Glycolic acid is highly soluble in water. The IUPAC name of salicylic acid is 2-Hydroxybenzoic acid.įigure 2: Chemical Structure of Glycolic Acid These crystals can undergo sublimation at 76 ☌ (sublimation is the conversion of a solid directly into its vapor phase without going through a liquid phase). The melting point of salicylic acid crystals is 158.6 ☌ and, it decomposes at 200 ☌. The molar mass of this compound is 138.12 g/mol. The chemical formula of salicylic acid is C 7H 6O 3. It is a colorless to white crystalline solid that is odorless. Salicylic acid is a medication that helps to remove the outer layer of the skin. Key Terms: 2-Hydroxybenzoic Acid, Glycolic Acid, Hygroscopic, Pepto-Bismol, Salicylic Acid, Sublimation What is the Difference Between Salicylic Acid and Glycolic Acid The main difference between salicylic acid and glycolic acid is that salicylic acid is poorly soluble in water whereas glycolic acid is highly soluble in water. But these compounds have different chemical and physical properties. Glycolic acid is also used in skincare products. Salicylic acid is mainly used in medications due to its ability to remove the outer layer of skin. Salicylic acid and glycolic acid are organic compounds that are used in many industries as raw materials or ingredients. Main Difference – Salicylic Acid vs Glycolic Acid
