The zinc oxide particles in ZinClear-IM consist of primary particles, which form aggregates up to a few tens of micrometers in size. Larger aggregates have a unique porous structure that provides a closer match between the refractive index of the particle and the refractive index of the emollient, resulting in high transparency. A typical SEM image of the zinc oxide particles in ZinClear-IM is shown in the image below. This image illustrates that the zinc oxide is present in the form of porous particles having sizes mostly in the micrometer range.

Technical Details & Test Data
- Physical Characteristics
ZinClear-IM dispersions are supplied in the form of a viscous, free flowing liquid. The dispersion is pale yellow to yellow-green in colour but when applied to the skin will remain highly transparent, even at high loadings. A comparison of ZinClear-IM transparency to competitor ZnO products is shown in the graph below.
The market leading transparency of ZinClear-IM dispersions is also shown in the draw-down charts below against competitor materials.
Broad Spectrum Protection
ZinClear-IM has a broad absorption profile spanning both UVA and UVB. ZinClear-IM may be used alone or in combination with other UV filters to produce high SPF sunscreens that will meet the UVAPF>(1/3)SPF criterion where required. ZinClear-IM can also be formulated for the critical wavelength to reach 370nm where required. ZinClear-IM is photostable in formulations and is not prone to degrade or lose effectiveness under influence of UV.
- Typical Performance and Required Loadings
- ZinClear-IM can be formulated at high loadings to achieve high SPF without compromising the clarity of the end product.
- The table below serves as a guide only, as the SPF will additionally depend on the type of formulation.
SPF Target ZinClear-IM Loading Equivalent ZnO Loading
<15 15-25% ~7.5-12.5% 15-25 30-40% ~15-20% 30+ 40-50% ~20-25% Antaria recommends that formulators conduct in vivo SPF testing when possible during product development to ensure reliability of results.

- Storage and Shelf Life Conditions
- It is recommended that all ZinClear-IM dispersions be well mixed prior to use. A minor loss of product as sediment in the bottom of the container may be experienced.
- ZinClear-IM50 JJ has a stability shelf-life of 24 months when stored under standard conditions (above 5°C and below 30°C) after which retest is required to extend the shelf life to 3 years from manufacturing date.
