Hello Fluoride Free Toothpaste Superfresh Spearmint
Lower PFAS concern, typical toothpaste formulation with no coating or water-repellent treatment.
Hello's Fluoride Free Superfresh toothpaste contains no known PFAS-prone materials. Standard toothpaste bases (glycerin, silica, xanthan gum) do not require water-repellent or nonstick treatments. No brand PFAS claim exists, but the product category and common Hello formulations present minimal PFAS risk.

The full breakdown
What it's made of and why it matters
Hello Superfresh uses a water-glycerin gel base with silica as the primary abrasive, a standard and well-tolerated formulation in modern toothpaste. Silica in cosmetic-grade toothpaste is regulated and insoluble, meaning it does not leach into saliva or systemic circulation during normal use. Glycerin is a humectant that poses no known toxicity at the concentrations used in oral care products. The 'fluoride-free' positioning means absence of sodium fluoride or other fluoride salts, which some consumers prefer despite fluoride's established safety and efficacy in dental health.
The brand's record and disclosure
Hello Products (a Colgate-Palmolive subsidiary) markets itself as a conscious consumer brand emphasizing natural and clean-label positioning, though the company maintains limited transparency on full ingredient sourcing and third-party testing. The brand is not known for major recalls or established cosmetic safety violations. Independent certifications (e.g., Leaping Bunny, vegan claims) are stated on packaging but formal safety certifications such as FDA pre-approval testing or dermatological review are not publicly detailed. PFAS stance is unstated, consistent with most mainstream toothpaste manufacturers who do not proactively disclose or test for PFAS in oral products.
How it compares in its category
Fluoride-free toothpastes represent a minority segment; most mainstream options contain fluoride (0.15% sodium fluoride or equivalent). Among fluoride-free alternatives, Hello sits in the mid-tier for ingredient simplicity and brand transparency, comparable to products like Tom's of Maine or Davids. Compared to conventional brands (Colgate, Crest), Hello emphasizes fewer synthetic additives and avoids some color additives and preservatives, though functional performance (plaque removal, sensitivity relief) is less clinically established. The spearmint flavor is a cosmetic choice without safety implications.
If you buy it
Use as directed (pea-sized amount, twice daily for adults; parent-supervised for children under 6 to minimize ingestion). No special storage or shelf-life concerns beyond standard toothpaste; keep tube sealed and store at room temperature away from heat. Because this product is fluoride-free, consult your dentist about whether your water supply is fluoridated or whether additional fluoride sources (rinse, supplement) are appropriate for cavity prevention. Discontinue use only if you experience allergic reactions to spearmint flavoring or silica, which are rare.
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.”
Formaldehyde releasers or preservatives
Standard cosmetic-grade preservatives in Hello products (likely methylchloroisothiazolinone or sodium benzoate, both permitted) do not include formaldehyde-releasing agents. No recalls or warnings for formaldehyde contamination in this product line are on record.
Heavy metals in colorants or mineral abrasives
Silica used in toothpaste is cosmetic-grade and regulated for purity; lead and cadmium contamination in mineral-based abrasives is rare in mainstream brands due to supplier standards. No testing data publicly available for this specific product, but no recalls or warnings suggest contamination.
Talc contamination
Toothpaste formulations typically use silica rather than talc as the primary abrasive. Hello Superfresh does not list talc in its ingredients, eliminating asbestos contamination risk associated with some talc mining.
1,4-dioxane (cosmetic contaminant)
1,4-dioxane is a potential trace contaminant in products derived from ethoxylated ingredients (e.g., polysorbate emulsifiers). Hello does not publish analytical testing for 1,4-dioxane. Risk is low given the product's simple formulation and lack of documented contamination in mainstream toothpastes.
Fragrance allergens (spearmint/menthol sensitization)
Spearmint flavoring is generally well-tolerated, but individuals with contact dermatitis or oral mucosa sensitivity may experience irritation. Natural spearmint oil or synthetic spearmint flavor compounds can trigger reactions in sensitized users; testing before full use is prudent if you have known fragrance sensitivities.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
