Formulation and interest of a decorative emulsifier-free O/W emulsion with a positive zeta potential.
The aim of this study was to formulate an emulsifier-free foundation with a positive zeta potential. This formulation was achieved through a comparative study carried out on 16 cationic hydrogels. Measurements of the cationic activity of those gels were undertaken. Sixteen emulsions, including 0.4% of cationic gel, were formulated and the zeta potential of each was quantified. No correlation between those two measurements could be established. Pigments introduced in the emulsion to obtain a foundation slightly reduced the zeta potential value of the formula. The skin coloration induced by the application of the formula with a positive electric charge was found more stable than that of classical and transfer-proof formulae. Moreover, this formula displayed a higher hydrating potential compared to transfer-proof formulae.
