Zinc Oxide, Micronized & Coated

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. Fine white transparent powder with minimal whitening effect, faint odor. Dispersible but not soluble in oils.

CAS: 1314-13-2, 2943-75-1

INCI Name: Zinc oxide, triethoxycaprylylsilane

Use: To be dispersed into the oil phase of formulation. Usually combined with organic sunscreens, typical use level 3-6% when combined with organic sunscreens, use level when given alone 3-25%. For external use only.

Applications: Sun care products, makeup products. Does not provide coverage in makeup due to its transparency. If coverage is needed use regular zinc oxide or titanium dioxide.

Country of Origin: USA

Raw material source: Metallic zinc

Manufacture: Zinc oxide is produced from metallic zinc which is melted in a graphite crucible and vaporized at high temperatures (around 1000 °C). Zinc vapor reacts then with the oxygen in the air to give zinc oxide. The preparation of micronized (or nano-sized) zinc oxide is then carried out by the precipitation method where zinc salt solutions are reacted with alkali solutions.

Animal Testing: Not animal tested

GMO: GMO free (does not contain plant-derived components)

Vegan: Does not contain animal-derived components

Regulatory Information: Sunscreens are registered as API (Active Pharmaceutical Ingredient) or OTC-drug with the FDA. This means that, if you want to sell products containing a sunscreen, your facility must be registered with the FDA and operate under cGMP guidelines. Further information about the FDA regulation of sunscreens can be found here.
