SunSafe® Report Status Under Review: 

Titanium Dioxide Tints - found in coloured Zinc Sticks

 Reef category SunSafe® - In review 

Summary:

This is a mineral-based, low-risk formula with strong environmental positioning.

No major reef-harming UV filters detected.

A lower-risk mineral formula overall, with precautionary reef moderation applied due to titanium dioxide environmental uncertainty.

 

Case Study:

Why this matters in the SunSafe® Standard

Found in zinc sticks - These formulas are primarily built on zinc oxide — a mineral UV filter we currently rate as moderately reef-conscious within the SunSafe® framework.

While titanium dioxide is widely approved and considered lower concern, questions remain around aquatic accumulation and nano TiO₂ behaviour in marine environments.

Current evidence suggests TiO₂ can accumulate in aquatic systems, and some nano TiO₂ studies have demonstrated oxidative stress impacts in marine organisms under laboratory conditions.

Environmental consensus, however, remains unresolved due to multiple interruptions in real world application.

As a result, these products still perform strongly overall, but precautionary reef score moderation was applied within the SunSafe® framework pending greater transparency around particle size and coating technologies.

SunSafe® Says:

✔️ Suitable for: Everyday wear, outdoor sport, mineral UV protection

⚠️ Reef category moderated pending further environmental transparency around titanium dioxide particle technologies.
