Dosage Guideline

The optimal dosage Valida S191C, 3% depends on the required functionality, as well as the nature of the other ingredients in the formulation. Note that adding Valida S191C, 3% will not result in an immediate thickening effect. The primary functionality of Valida S191C, 3% is stabilization at low viscosity. A combination of Valida S191C, 3% and a thickener is recommended when a ‘gel-like’ system is required.
