Sun Bum Mineral Sunscreen Lotion SPF 50
Lower-risk option; mineral sunscreens typically skip PFAS-heavy waterproofing.
Mineral sunscreen with zinc oxide and titanium dioxide avoids the water-resistant coatings that often contain PFAS. Sun Bum provides no PFAS statements or independent test results.
We flunk more products than we pass. This one earned its grade. How we grade
Material
Mineral sunscreen (zinc oxide/titanium dioxide base)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
cosmetics is a category where PFAS exposure is more common.
Fragrance allergens (undisclosed components)
Sun Bum lists 'fragrance' in the formula but does not publicly disclose specific fragrance compounds. Fragrance is a common sunscreen allergen source; individuals with fragrance sensitivity or compromised skin barriers may experience contact dermatitis.
Formaldehyde / VOCs
Sunscreen lotions require preservatives to prevent bacterial and fungal growth. Sun Bum does not disclose preservative type on widely available public materials; formaldehyde-releasing agents are used in some products but no specific issue is documented for this brand.
Source: ATSDR ↗Skin irritation from zinc oxide or titanium dioxide at high concentrations
Mineral actives are inert but can cause irritation, dryness, or rash in individuals with very sensitive skin or eczema-prone conditions. Individual tolerance varies; patch testing on a small area first is prudent for first-time users.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Heavy metals
Titanium dioxide used in sunscreens is cosmetic-grade and regulated under FDA rules; no public recalls or contamination reports for Sun Bum specifically. Minor trace metals are possible but well below safety thresholds in approved products.
Source: FDA ↗Talc contamination in mineral formulas
Sun Bum Mineral Sunscreen does not list talc as an ingredient, so this is not a concern for this specific product. Some mineral sunscreens use talc as a filler; this brand avoids it.
The full breakdown
What it's made of and why it matters
Sun Bum Mineral Sunscreen uses zinc oxide and titanium dioxide as active UV filters, which sit on skin rather than absorb into it. This formulation avoids the synthetic organic UV absorbers (oxybenzone, avobenzone) found in chemical sunscreens, which carry endocrine concerns and are linked to PFAS-prone waterproofing additives. The mineral base is photostable and non-irritating for most users, though the white cast and potential grittiness are cosmetic trade-offs, not safety issues.
The brand's record and disclosure
Sun Bum does not publish detailed ingredient transparency reports or third-party certifications (e.g., EWG Verified, Reef Safe seals) that would signal independent safety vetting. No major recalls or regulatory actions on record for this product line. The brand has not publicly committed to PFAS avoidance, though the mineral-only formula naturally avoids the worst PFAS sources. Limited disclosure of fragrance components or potential allergens on public materials.
How it compares in its category
Mineral sunscreens are generally considered lower-risk than chemical alternatives for PFAS and endocrine disruption, though they lag in cosmetic elegance (thickness, white residue). Sun Bum's offering is mid-tier in terms of transparency; premium brands like Blue Lizard or EWG-listed options provide more detailed allergen and fragrance disclosure. Reef-safe certifications are absent, which may matter if use near sensitive ecosystems is a concern.
If you buy it
Apply generously (about 1/4 teaspoon for face) 15 minutes before sun exposure and reapply every 2 hours or after swimming. Store below 25°C in a cool, dry place to prevent active ingredient degradation. Discontinue if rash or irritation appears; mineral sunscreens can cause contact dermatitis in sensitive individuals. Do not rely on it alone for sun protection; use with clothing and shade, especially for extended outdoor periods.
