Titanium Dioxide for white oil-based soap

Based on the product descriptions, the listed Titanium Dioxide products, such as "Titanium Dioxide 250nm Pigment (Non-Treated)", "Titanium Dioxide 300nm Pigment (Non-Treated, Color-Controlled)", and "Titanium Dioxide 250nm Pigment (Non-Treated, Eco)", are described as being used only in makeup products and are dispersible in water.

For coloring oil-based soap white, you typically need a pigment that can disperse well in oil or the soap base. The descriptions of these specific products indicate they are intended for water-based dispersion in makeup, which may not be suitable for your oil-based soap application.

It's recommended to look for a grade of Titanium Dioxide specifically formulated or recommended for use in soaps or oil-based systems to ensure proper dispersion and stable white color.
