Zinc oxide powder

Zinc oxide (ZnO) is a natural mineral which has been used safely for generations to shield against the harmful effects of the sun. It is a very fine, amorphous white or ivory-white powder. Our zinc oxide is of extremely high quality and purity to meet all U.S. Pharmacopoeia and European Pharmacopoeia standards as per USP33 NF28, it is made from primary grade zinc. Our zinc oxide is not micronized and is not classified as NANO.

Zinc oxide is a superb broad-spectrum blocker, it blocks the sun’s rays (acts as a reflective shield). It offers broad spectrum protection. In turn, this reduces UVA-induced free-radical production in the deeper layers of the skin.

From the manufacturer: This product is non-GMO, has not been irradiated nor produced with sewage sludge and is food grade. (Note from Camden-Grey: All products sold on our website are for external use only.) This is a/k/a French process zinc oxide which is produced from primary grade zinc. All natural minerals, including clays and zinc oxide, contain trace amounts of heavy metals including lead. However, given that the zinc oxide Camden-Grey purchases is sold to us as cosmetic grade, the product consistently tests below the USP protocol limit for lead.

Zinc oxide is an ingredient found in many products, including certain creams and ointments used to prevent or treat minor skin burns and irritation, it is nearly insoluble in water. Zinc oxide forms a protective physical barrier over the skin and stops harmful UV rays, providing the most complete protection. Zinc oxide is particularly valuable because of its ability to filter UVA as well as UVB light, giving broad protection from damaging sunlight. It can be used in ointments, creams and lotions to protect against sunburn. It should not be inhaled in powder form for continuous periods of time or on a daily basis. All products sold on our website are for external use only.

Various ointment-based preparations which incorporate zinc oxide are water repellent and stay on even during swimming. A deodorant can be made simply from zinc oxide which works by killing underarm bacteria to eliminate or reduce smell. You can also use zinc oxide as a diaper rash ointment or on your nose (as a paste mixed with water) as a complete sun block; just add distilled or purified water to desired consistency. Zinc oxide is the main active ingredient in Desitin Diaper Rash Ointment.

Historically, when used in sunscreens, zinc oxide is visible, giving the skin a white color, it sits on the skin. It s non-irritating and non-allergenic.

Arsenic: No more than 6 ppm.

Lead: Typical 15 ppm.

Particle size (microns): Typical 0.24. Mean particle size: min. 0.24, max. 0.35. This is 112USP used in cosmetic products.

Country of origin: Canada.

INCI: Zinc oxide.

Shelf life: The overall concensus is that zinc oxide does not have an expiration date and does not deteriorate over time. Zinc oxide is said to have an indefinite shelf life, is extremely stable and can tolerate high heat, UV light and moisture without disintegration. Some suppliers, in order to play it safe, state that zinc oxide (when properly stored, tightly sealed) has a shelf life of up to 3 years.

PACKAGING:  Purchasing 10 lbs., 25 lbs. or larger quantities of a powder product (clay, pumice or any product listed in our Salts, Sugars & Powders category) doesn’t mean you’ll receive one package containing all of the pounds purchased.  We will prepare individual plastic bags whose weights will add up to the total number of purchased pounds.  For example, do not expect 25 lbs. of a powder product to be packed in one 25 lb. bag.  There could be the rare occasion where we could receive from the manufacturer a 50 lb. factory-sealed bag and we’ll turn around and ship the same bag to a customer who ordered 50 lbs. of a powder product.
