CO20R7C

CO20R7C is a dispersion containing 20% surface treated Red 7 Lake in Castor Oil.

Kobo's pigmentary dispersions are widely used in colour cosmetics due to their multiple benefits over dry pigment powders. Dry pigments tend to aggregate in formulations which can affect the color strength, gloss and opacity. The colour intensity and opacity are usually highest when the aggregate particle size is closest to the primary particle size. The pigments in Kobo's pigmentary dispersions are surface treated to improve the ease of dispersion and stability. Kobo's pigmentary dispersions offer full colour development, improved gloss and ease of use.

CO20R7C is a dispersion containing 20% Red 7 Lake in Castor Oil. The pigments are surface treated with Kobo's patented ITT (Isopropyl Titanium Triisostearate) treatment prior to dispersion. ITT treatment forms a uniform coating of lipophilic isostearate groups, which greatly improves the dispersibility of powders in various organic oils. ITT treatment reduces oil absorption of powders so they can be used at substantially higher loading in formulations without causing a dramatic viscosity increase. ITT treatment has good skin affinity due to the isostearate surface groups.

CO dispersions are recommended for use in anhydrous formulations (e.g. solid sticks such as lipstick, and blush) and may also be used in emulsions (e.g. liquid and cream foundation).
