The absence of waxes, in combination with the thixotropic properties of Gilugel® allows the formulation of very light W/O emulsions (containing more than 80% water) with excellent skin sensory characteristics.
In formulations containing TiO2 , ZnO or Iron Oxide pigments, Gilugel® forms a layer on the surface of the particles which leads to improved pigment dispersion and prevention of reagglomeration, even on storage of the end product. This means that in sun care emulsions, a reduction in sun protection factor (SPF) over time is avoided and a favourable relationship is achieved between the level of pigments applied and the resulting SPF.
Tests have shown that sun care formulations containing Gilugel® maintain their SPF even after 3 hours of swimming. This water resistance can be attributed to the film forming characteristics of Gilugel® on the skin.
Thermostability Gilugel® lends high thermostability to formulations. In sun care products, for example, changes in viscosity are minimal even at extreme temperatures.
