High purity ultrafine
zinc oxide

Advanced materials:
Z-ULTRA™

Evolved over time, to make the intrinsic properties of zinc oxide working at the highest efficacy and peak performance levels
ZOA’s Z-ULTRA™ ultrafine or sub-micron particle size zinc oxide powder produced from high purity zinc oxide Z-PHARM™: negligible heavy metals, and pristine white zinc oxide powder.

Z-ULTRA™ with its submicron primary particle size and higher Specific Surface Area [BET SSA] aggregates ideally in a transparent sunscreens, BB creams, and cosmetics.

Due to its natural astringent, antibacterial and skin-regenerating properties, zinc oxide is commonly used as an Active Pharmaceutical Ingredient (API) by the pharmacy industry in nutraceuticals, topical creams, shampoos, medical tapes and powders.

These zinc oxide products help treat minor burns, infections, diaper rash, eczema and other minor skin conditions. zinc oxide is also a critical ingredient in sunscreen as it effectively absorbs radiation in harmful UVA and UVB rays.

Studies show that these reflective properties become even more prominent in ultrafine particles. Z-ULTRA™ superfine submicron zinc oxides are available in 3 specific grades, which provide remarkably superior broad-band UVA and UVB absorption properties and enhanced levels of transparency.

In addition, ZOA has specifically chosen not to stock zinc oxides with coatings (e.g. Triethoxycaprylylsilane) as they do not align with our ingredient standards. For many years, our uncoated, dispersion-ready zinc oxide products have been safe to use as an API in topical, cosmetic, and nutraceutical products. Reach out to our team to learn more today.

Manufacturing your product with zinc ingredients ensures that you’re doing your part in protecting the earth and developing a more ethical, modern life.

Our zinc oxide raw materials are produced by the French (indirect) process. This process has many advantages compared to others, including:

  • Consistent high purity & fine particle size
  • Consistent white colouring

Broadband UV blocker

  • Z-ULTRA™ superfine zinc oxide made in Australia from Australian zinc.
  • Z-ULTRA™ superfine sub-micron zinc oxide is available in 3 specific grades focused around absorbance performance, and transparency.

Visible light transparency

  • Efficacy testing highlights improved transparency characteristics from increased primary particle specific surface area increases.
  • These improved traits relate to higher on-skin transparency in personal care applications.

Zinc oxide in the Beauty Industry

Another versatile advantage of zinc oxide is its positive impact on the beauty industry. Its non-irritant, anti-inflammatory properties make it a gentle, mineral-based alternative to harsh chemical-based cosmetic products.

Zinc-based cosmetics that are becoming increasingly popular in the industry include foundation, face powder, lipstick, moisturiser, primer, and more.

Z-ULTRA™ ultrafine primary particle size and high Specific Surface Area (SSA) make it the superior choice for all of these personal care and health products. To learn more about Z-ULTRA™, enquire with our team today.

Zinc oxide in Health Products

Zinc oxide is an essential API in vitamins and dietary supplements as its high nutritional value helps balance out the detrimental effects of a zinc deficiency. Because of this, it is also used in other food fortified products, including breakfast cereals, nutrition drinks and bars.

Zinc oxide can also be formulated into many oral health and health products such as toothpastes, dental cements, shaving and grooming products, and nappy rash creams.
