Abstract:Ultra-fine particles of titanium dioxide (TiO 2 ) and Zinc oxides (ZnO) are very attractive as UV-protecting ingredients in cosmetic products. The UV-scattering behavior of single TiO 2 suspensions and complex ones in a silicone oil is studied in relation to rheological properties. To control the dispersion stability of suspensions, three polyoxyethylene(POE)-modified silicones of branch-type, (AB)n-type, and ABA-type are used as dispersants. Irrespective of molecular structure, the dispersants can stabilize t… Show more
