Description
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.
Benefits
  • Reflects sunlight (UVB rays)
  • Has soothing effects and can be used for skin irritations
  • Has some antimicrobial properties
  • Transparent look with minimal whitening effect
  • Coated zinc oxide is more compatible with acrylate-based thickeners (e.g. carbomer) than non-coated zinc oxide, because it has alkaline properties in formulations and needs therefore less or no neutralizers like TEA or NaOH
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.

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.

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 in our resource section.If used as colorant, Zinc oxide is a FDA-approved color additive but is exempt from batch certification. It is safe for use in coloring cosmetics generally, including cosmetics applied to the area of the eye, in amounts consistent with good manufacturing practice.
