BWBO-11SP (C33-7001)

BWBO-11SP (C33-7001) is Black Iron Oxide that has been surface treated with Kobo's patented 11SP treatment.

11SP is a double treatment of Silane and Polyhydroxystearic Acid that renders powders both hydrophobic and lipophilic. The 11SP treatment makes powders easy to disperse in esters and hydrocarbons as well as silicones, even at high loading. 11SP treated powders can be used to make pressed powders with an ultra creamy feel and excellent spreadability even when dimethicone is the sole liquid binder.

Chemical Description: CI 77499 (Black Iron Oxide), Triethoxycaprylylsilane, Polyhydroxystearic Acid
