Many sunscreens use zinc oxide particles that have been coated with an inert substance, usually triethoxycaprylylsilane, to make it easier to mix with the other ingredients and less photo-reactive (see below). At Badger we decided to only use uncoated pharmaceutical grade zinc oxide in our products for the following reasons:
Description: USP grade zinc oxide that consists of approximately 98% micronized zinc oxide and 2% hydrophobic coating material (silicone derivative). Derived from natural zinc ore, super-finely micronized. Particle size <200 nanometer (<0.2 micrometer), mean particle size 86 nanometer.
Therefore a non-nano particle is larger than 100nm. Our Babo clear zinc has been tested to be 700 nm so far more above 100nm.

It can stand alone as a sunblock because it is truly effective against UVA, UVB and even ...
A zinc oxide coating is a solution containing zinc oxide, which is an inorganic compound, generally as a means to prevent corrosion. An inorganic compound is a chemical mixture that does not contain carbon or organic chemicals. Zinc oxide paints or coatings are particularly useful for application...
Hello Joe, Do you have any articles that talk about the pros or cons of powder coating with zinc primer vs galvanizing and then powder coating over top? Thanks for sharing your wealth of knowledge :) Sincerely, Allison Lee Boise, Idaho Hi Allison, It's nice to hear from you.
Zinc (oxide / citrate), Dicalcium phosphate, microcrystalline cellulose, vegetable stearic acid, vegetable magnesium stearate, croscarmellose sodium, silicon dioxide, and aqueous film coating ( purified water, hydroxypropyl methylcellulose, and vegetable glycerin ).
