What pH is best for salicylic acid?
You can assume that the concentration of Salicylic Acid is too low if displayed in the last part of the ingredients list. As well as this, it is important that the product has the correct pH level (acidity), usually between 3 and 5. The skin will become easily irritated if the pH level is lower than 3.
Is salicylic acid polar or nonpolar?
* It is important to note that molecules have polar bonds, but overall polarity is generally discussed as a relative thing. i.e. salicylic acid is more polar than hexanes.
