Salisol HS is a water soluble UVB filter and the solubility could be further improved by increasing the pH of formulation and adding buffer solution i.e. NaOH or TEA. In formulations the pH-value need to be buffered around 7, at lower levels precipitation could be a result of reverting to its acid form. Salisol HS combining with oil soluble UV absorbers to get a high SPF value.
