Salisol® 4

Salisol 4 helps prevent the integrity of other cosmetic ingredients from deteriorating under the sun. The sulfonic acid group makes Salisol 4 soluble in water. It should be neutralized before adding into formulation by neutralizing agents like Triethanolamine, NaOH, etc. The yellow color of Salisol 4 is intensified by neutralization; this may change the coloration of the solution.
