This presentation discusses several research studies on the effects of adding SOLESPHERE silica microsphere gels to cosmetic and skincare formulations. Several grades are compared with the most common plastic bead fillers. Tests compare:

• Frictional properties like softness and smoothness
• Absorption of oil and sebum with a glossmeter and subumeter
• Formation of shiny spots on the skin
• Achieving gloss and matte effects
• Physical properties of bead fillers
• Formulation stability of lipstick
• Smooth application and spreadability
