Gel Based Sunscreen Containing Surface Modified TiO₂ Obtained by Sol-Gel Process: Proposal for a Transparent UV Inorganic Filter

Figure 5

Shear viscosity as a function of shear rate of gel based formulation and, also, formulations containing 15% of commercial TiO₂ and 15% and 25% of P0.05H1 TiO₂ nanoparticles. The insert displays a zoom in the formulations without commercial TiO₂ nanoparticles.
