The main ingredient in the formulation of creams and products for sun care is the sun protection.

Metal oxides, such as titanium dioxide (TiO2) and zinc oxide (ZnO) may be counted among the sun protections most used.

Optimal water dispersion of these metal oxides is important to guarantee an efficacious sun product, homogeneous in consistency for easy application.

HYDRODIS SUN is the dispersing polymer suggested by Bozzetto to solve the problem of optimal dispersion of inorganic sun protections in water.
