Zinc Oxide Pharma Netherlands 1 kg

What makes pharmaceutical grade zinc oxide so versatile across industries

Zinc oxide of Dutch pharmaceutical purity is one of those raw materials whose demand stretches far beyond pharmacy shelves. This fine white mineral powder is used in barrier ointments and protective pastes, in decorative and skincare cosmetics, in the rubber industry as a vulcanization activator, in ceramics and glass manufacturing for glazes, and in coatings for improved corrosion resistance. In our catalog it belongs to the Mineral fillers category, which brings together powders used for texture, opacity and formulation stability.

In pharmaceutical and dermatological formulas this mineral is valued as a skin protectant: it appears in diaper rash pastes, soothing ointments for irritated skin, drying and mattifying creams, and barrier products for sensitive areas. Thanks to its strong reflective properties in the ultraviolet range, it is widely used as a physical filter in mineral sunscreens, often paired with titanium dioxide to broaden protection. In color cosmetics the powder gives pressed and loose products opacity without heaviness, while also helping control shine and sebum throughout the day.

Within mineral cosmetic formulas, zinc oxide pairs naturally with other texturizing powders. Combined with Ultrafine Silk Powder, it gains a softer, silkier glide on skin, while Pearl Powder adds a subtle natural glow without weighing the formula down. A small addition of Magnesium Myristate improves pressing behavior in powder blends and helps particles bind into a smoother, more cohesive texture.

On the industrial side, zinc oxide acts as an activator in rubber vulcanization, typically dosed around three to five parts per hundred parts of rubber. In ceramics and glass production it is introduced into glazes to improve heat resistance and surface finish. In cosmetic and pharmaceutical recipes, dosage generally ranges from five to forty percent depending on the intended function, with light powder bases needing only a small fraction and dense protective pastes requiring a much higher share.

The powder should be introduced during the cold phase of production, dispersed thoroughly into the oil phase or with a suitable dispersant before combining with water, which helps prevent clumping. No heating of the powder itself is required, but the temperature of the finished emulsion should stay below around forty degrees Celsius during incorporation to keep particle distribution even. The one kilogram packaging suits small-batch and studio manufacturing, formulation testing, and independent cosmetic or pharmaceutical workshops that need a reliable stock of quality raw material without excess surplus.

Store zinc oxide in a dry, tightly sealed container away from direct sunlight and moisture, since the powder tends to clump when exposed to humid air. Under proper storage conditions its properties remain stable over an extended period.

Barrier balm stick with zinc oxide

Zinc oxide 120 g

Beeswax 150 g

Coconut oil 200 g

Shea butter 100 g

Castor oil 80 g

Vitamin E oil 5 g

Melt the beeswax, coconut oil, shea butter and castor oil together in a heatproof container over a water bath until fully liquid and combined. Remove from heat and let the mixture cool slightly to around fifty degrees Celsius, then sift the zinc oxide in gradually while stirring continuously to avoid lumps forming. Once the powder is fully and evenly dispersed, blend in the vitamin E oil and pour the mixture into balm tins or stick containers before it begins to set. Allow the balm to cool undisturbed at room temperature until fully solidified before sealing the containers.
