EFFECT OF INGREDIENT QUALITY ON COSMETIC FORMULATION

INTRODUCTION The nature and the quality of a constituent in a formulation may have an impact on its final stability. Consequently, the stability of the dispersion (suspensions, emulsions, foams, …) have to be control for all supplier to validate the stability. When dealing with natural products, the quality of the raw material from one supplier to another one may change significantly the properties of the final formulation. In this note, the effect of two identical natural oil coming from two different suppliers was studied using the Turbiscan™ technology.
