Salicylic Acid (CAS 69-72-7)

Application and positioning

A β-hydroxy acid used for keratolysis and for acne, typically at 0.5–2 % in leave-on products. Cosmetic grade is controlled on phenol content and on heavy metals; the technical grade is not interchangeable. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots, with the purity and microbiological documentation cosmetic formulators require.
