Titanium Dioxide (Non-Nano Particle)
Titanium Dioxide is an inert mineral found in the earth that is valued in cosmetics for its opacifying and UV protection properties. Though it is naturally ocurring, it undergoes synthetic processing to remove impurities or contaminants, such as by heavy metals found in the earth.
We use titanium dioxide in cream formulas only, as it can be carcinogenic when inhaled in powdered form.1 Our titanium dioxide is non-nano particle, though there is no evidence to suggest that titunium dioxide - nano particles or larger - is able to penetrate beyond the outermost layer of the skin.2
