Close Up Fire and Freeze Toothpaste
Lower concern, toothpaste inherently low-risk; no PFAS indicators typical for this category.
Close Up Fire and Freeze is a conventional gel toothpaste with no known PFAS-prone ingredients or coatings. Toothpaste formulations rarely require water-repellent or stain-resistant treatments that would introduce PFAS.

The full breakdown
What it's made of and why it matters
Close Up Fire and Freeze is an aqueous gel toothpaste built on a silica abrasive system (standard for whitening formulas) suspended in sorbitol and glycerin humectants. The 'fire and freeze' effect comes from flavor compounds and mild sensory agents like menthol or cinnamon derivatives, not chemical irritants. Silica at toothpaste-typical concentrations (under 7% by weight) is well-established as safe for oral use; sorbitol is a sugar alcohol that does not feed cavity-causing bacteria, making it a common choice in formulations targeting enamel care.
The brand's record and disclosure
Closeup (owned by Unilever) does not publish detailed ingredient safety disclosures or third-party certifications for this product beyond standard regulatory compliance. The brand has no known recalls or safety controversies tied to Fire and Freeze in public records. Unilever maintains general safety statements on their oral care portfolio but does not highlight specific testing or heavy-metal screening for this line, which is typical for mass-market toothpaste.
How it compares in its category
Fire and Freeze sits in the mainstream whitening-and-sensation segment; its formulation is materially similar to competing brands like Colgate Max White or Sensodyne Rapid Relief. No published data suggests it carries higher heavy-metal burdens or fluoride levels than competitors. The flavor-driven positioning (versus clinical claims) is a minor differentiator but does not introduce category-atypical safety risks.
If you buy it
Use twice daily in pea-sized amounts; do not swallow. Silica abrasives can be mildly gritty and may cause slight enamel wear with aggressive brushing over years, but this is true of most whitening toothpastes. Store at room temperature away from direct heat (silica suspensions remain stable under normal bathroom conditions). Replace the tube when empty or if the gel separates visibly; a 6-month shelf life after opening is typical for aqueous formulations.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Silica abrasive (enamel wear)
Silica in toothpaste is safe at regulated concentrations, but aggressive or frequent brushing with any silica-based whitening paste can incrementally wear enamel over years. This is not unique to Close Up and is a category-level concern, not a product-specific flaw.
Fluoride toxicity (if ingested)
No product-specific data on fluoride concentration in Fire and Freeze is publicly available, but standard toothpaste fluoride (typically 1000-1500 ppm) is safe at recommended use levels. Accidental swallowing by children in large amounts poses a risk; use supervision and store out of reach.
Flavor agent allergens
The 'fire and freeze' sensory profile likely includes menthol, cinnamon, or capsicum derivatives. Individuals with mint or spice sensitivities may experience oral irritation or allergic contact dermatitis on the gums or lips; check full ingredient label if you have known sensitivities.
Colorants and pigments (heavy metals)
No heavy metal contamination in pigments has been reported for Close Up products. Toothpaste colorants are regulated by FDA and typically do not accumulate systemically given the brief oral residence time and minimal ingestion.
Formaldehyde-releasing preservatives
Toothpaste formaldehyde releasers (like imidazolidinylurea) are not typical in this product category or brand. Standard aqueous gel toothpastes use potassium sorbate or sodium benzoate, which do not release formaldehyde.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
