Zinc oxide UV filters,
engineered for formulators.
Controlled particle size, consistent batches, and complete regulatory documentation — so your sunscreen formula behaves the same on the thousandth batch as it did on the first.
Three grades, one material system
Select by application and formulation constraints. Each grade is specified by particle size, surface treatment, and regulatory status.
UV Filter Grade
Optimised for UV attenuation in cosmetic emulsions. Available in coated and uncoated variants for different sensory profiles.
- Cosmetic grade
- D50 targeted
- Hydrophobic options
Surface Coated
Inorganic surface treatment to suppress photocatalytic activity and improve dispersion stability in oil and silicone phases.
- Silica / alumina coating
- Reduced photoactivity
- Improved dispersion
Standard Grade
For rubber vulcanisation, coatings, and plastics where UV resistance and reactivity matter more than sensory feel.
- Industrial grade
- High reactivity
- Cost efficient
The hard part is repeatability
Making zinc oxide is not the challenge. Making the same zinc oxide twice is. Particle growth during calcination, agglomeration during drying, and surface activity all drift between small-scale and production runs.
Our process controls target the variables that actually move the specification: precipitation parameters, calcination profile, and surface treatment — each verified by cross-method particle characterisation.
How we control itParticle size control
D50 and distribution width verified by laser diffraction, cross-checked against electron microscopy.
Surface treatment
Inorganic coating to reduce photocatalytic activity and stabilise dispersion.
Quality control
Specific surface area, crystal phase, moisture, and pH measured per lot.
Documentation that clears procurement
A material is only usable once it clears regulatory review. We keep the paperwork current so your registration team is not waiting on us.
