Dynasylan® 4150

Dynasylan® 4150 features chemical polarity yet remaining chemically not reactive. Such a non-coupling filler or pigment surface-modifier silane is used as a hydrophilic compatibilizer rather than as a covalent adhesion promoter. Due to its excellent wetting behaviour, Dynasylan® 4150 helps to control rheological properties and to reduce viscosity, allowing extremely high fillers loads in water and polar vehicles, permitting to achieve a powdery velvet touch sensation on the skin.

Product Features
Product Benefits

Due to their customized surface energy, the surface treated functional pigments and fillers are used in many cosmetic products in order to enhance various properties of the finished formulation such as skin feel, oil absorption, color and gloss. Dynasylan® 4150 helps to increase pigment dispersion predominantly in polar cosmetic vehicles, consequently reducing the pigment amount, thus leading to an intense color or enhanced gloss of a cosmetic formulation if this effect is targeted.

Product Application
  • Dynasylan® 4150 is a ready-to-use silane, soluble in water and most organic solvents. It can be added neatly to a blend of filler or pigment and resin, or it can be used for the pre-treatment of the filler or pigment.
  • Pre-treatment of the filler or pigment is best achieved in a high-speed mixer by spraying Dynasylan® 4150 into a well-agitated filler or pigment bed. In order to obtain maximum efficiency of the treated filler or pigment, a good distribution of Dynasylan® 4150 throughout the filler or pigment surface is essential.
  • If the surface area of a filler or pigment is unknown, 1 percent by weight of Dynasylan® 4150, based on filler or pigment, is a convenient initial basis for pre-treatment. Subsequently, the exact Dynasylan® 4150 loading should be determined empirically.
  • As a non-coupling silane, Dynasylan® 4150 can considerably reduce the dispersion viscosity of several fillers and pigments, consequently optimising the processability of formulations. Because of the excellent wetting and dispersion, high filler or pigment loads at a given viscosity can be realized with Dynasylan® 4150.
  • Dynasylan® 4150 can be used for the treatment of many common cosmetic fillers, including talc, mica, and silicates as well as metal oxide pigments, such as titanium dioxide, zinc oxide, and iron oxide.
