PT1BM60B

Dispersion containing 60% surface treated Black Iron Oxide in Phenyl Trimethicone. Surface treated with Kobo's patented ITT (Isopropyl Titanium Triisostearate) treatment

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 colour 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.

PT1BM60B is a dispersion containing 60% surface treated Black Iron Oxide in Phenyl Trimethicone. The pigments are surface treated with Kobo's patented ITT (Isopropyl Titanium Triisostearate) treatment. ITT treatment forms a uniform coating of lipophilic isostearate groups, which greatly improves the dispersibility of powders in various organic vehicles such as esters, natural oils and hydrocarbons. 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.
