Ingredient Transparency, Up Close: Why We’re Clay-Free and Third-Party Tested

Written by CareOnDaily Research Team

Recent news coverage and independent tests raised public questions about lead, arsenic, mercury, and cadmium in certain toothpastes. Limits vary by jurisdiction and product type, but the takeaway is simple: source quality and impurity control matter, especially with mineral ingredients.

What We Do at CareOnDaily

  • Clay-free by design: We avoid bentonite/clay abrasives and specify high-purity hydroxyapatite with traceable sourcing.

  • Third-party heavy-metal testing: We screen for Pb/As/Hg/Cd using validated methods (e.g., ICP-MS). We summarize method, LOQ, and results in consumer-readable language.

  • Low-abrasion philosophy: We design for enamel-safe whitening from the start (RDA aligned with ADA-Seal expectations: ≤ 250).

Beyond Safety: Why Hydroxyapatite?

Clinical literature (PubMed) suggests hydroxyapatite can remineralize early lesions and reduce sensitivity. This is why we center an HAp-based Smart Formula and keep the rest of the ingredient list tight.

Three Questions to Ask Any Brand

  1. Do you publish metals testing summaries? (method, LOQ, results)

  2. How do you spec and audit mineral ingredients?

  3. What’s the RDA and how is enamel safety validated?
