Zinc Oxide 1 kg

Why Industries Rely on Zinc Oxide Powder Beyond Just Sunscreen

Zinc oxide supplied in a 1 kg pack serves as a foundational raw material across pharmaceutical, dermatological, and cosmetic manufacturing, making it one of the most versatile mineral powders on the market. Within cosmetic formulation, this ingredient belongs to the UV and SPF Filters for Cosmetics category, functioning as a physical barrier that reflects and scatters sunlight rather than absorbing it. Unlike many organic filters that cover only a narrow wavelength range, zinc oxide provides broad-spectrum protection against both UVA and UVB radiation, which is why it remains a preferred choice for mineral sunscreen formulas worldwide.

Globally, demand for zinc oxide extends far beyond sun care. Pharmaceutical manufacturers rely on it heavily for diaper rash creams, soothing ointments, and antiseptic pastes thanks to its astringent and drying properties on irritated or weeping skin. In decorative cosmetics, the powder is valued as a mattifying, opacifying pigment for pressed and loose mineral powders. Beyond personal care, zinc oxide plays a major industrial role in rubber vulcanization, ceramics, and coatings production, where it acts as an activator or white filler. For a cosmetic ingredient supplier, however, the primary demand remains centered on skin protection and soothing skincare applications.

When formulating sunscreen emulsions, zinc oxide is typically added during the oil phase at temperatures around 70 degrees Celsius, with thorough dispersion required to prevent clumping and ensure even particle distribution throughout the base. Recommended usage levels range between 5 and 25 grams per 100 grams of finished product depending on the target SPF level. For a lighter, less whitening finish, formulators often blend standard zinc oxide with a micronized version such as Z-COTE, whose finer particle size produces a more transparent application on skin. To improve water resistance and help the mineral filter adhere longer to the skin surface, a film-forming agent like Glass cover can be incorporated into the formula. Zinc oxide also pairs well with organic UV filters such as PARSOL MCX, allowing formulators to build broad-spectrum protection while reducing the overall mineral load and preserving a smoother texture.

The 1 kg packaging is well suited for small to mid-sized cosmetic workshops and studio manufacturers running small-batch production, testing new sunscreen and skincare formulas, or needing a reliable stock quantity without frequent reordering of small containers. Store the powder in a dry, cool place inside a tightly sealed container, since moisture exposure can degrade its technical properties and cause clumping over time.

Soothing Zinc Oxide Diaper Cream

Zinc oxide 20 g

Shea butter 15 g

Coconut oil 10 g

Beeswax 8 g

Calendula infused oil 5 g

Vitamin E oil 1 g

Melt the beeswax, shea butter, and coconut oil together in a double boiler until fully liquid. Remove from heat and stir in the calendula infused oil, letting the mixture cool slightly before slowly sifting in the zinc oxide while stirring continuously to avoid lumps. Once the powder is fully incorporated and the texture is smooth, add the vitamin E oil, pour into a clean jar, and allow the cream to set at room temperature before sealing for storage.
