Ultra Silk (also known as Extender-W) is a mica and titanium blend that creates a smooth silky effect offering superior coverage.


RonaFlair® Extender W is an extraordinary functional filler with excellent light-diffusing, mattifying properties. The mica platelets are coated with colloidal titanium dioxide offering moderate coverage and a powdery, dry texture.


It is a great choice for pastel powders with reduced pearlescence - I like it to use it as a brow highlighter. It is also ideal for foundation products because it promotes a natural-looking complexion, and it makes a lovely natural blush if you want a quick glow on the run.


  • Great light diffusion
  • Mattifying powdery texture
  • Easy application to support the natural complexion
  • Perfect for pastel shades with reduced shine
  • Less masking and “chalky” than regular titanium dioxide


Use in very small amounts (1/2 teaspoon to 1 1/2 tablespoons finished product), to add to the adhesion of your product along with giving it a beautiful silky feel.  Your product will not end up with the amount of shine received by using sericite or bismuth.  If you do not require the spf properties of titanium dioxide in your formula, you can use this instead.


This is lovely in all foundation, primer, blush and eyeshadow formulas. Once you try it you will want to keep plenty in stock. It can also be used as a standalone eyeshadow highlight colour.
