Dosage Guideline

The optimal dosage Sappi Valida - S231C depends on the required functionality, as well as the nature of the other ingredients in the formulation. Note that adding Valida S231C will not result in an immediate thickening effect. The primary functionality of Sappi Valida - S231C is stabilization at low viscosity. A combination of Sappi Valida - S231C and a thickener is recommended when a ‘gel-like’ system is required.
