Third-party testing

Independent labs verify what love and craft alone cannot. Remin Care commissions accredited third-party testing for safety and shelf readiness — and shares evidence with wholesale accounts. We do not invent seals or publish fake certificates.

What we send out

Microbiology (TAMC / TYMC) — aerobic bacteria, yeast & mold counts on water-containing and leave-on formulas before release.
Preservative efficacy (challenge / PET) — USP<51>-style challenge on emulsions and other water systems to confirm the preservative system holds under inoculation stress.
Stability — accelerated and real-time appearance, odor, pH, and separation checks appropriate to the pack format.
Heavy metals (where relevant) — mineral / oral powders and key mineral inputs screened to cosmetic limits via ICP or equivalent.
Ingredient COAs — incoming actives (e.g. nHA, CBD where used, menthol USP, DMSO grade) released only with supplier COA; spot third-party verification when risk warrants.
Patch / HRIPT (selected SKUs) — human repeat insult or equivalent dermal screening before broad leave-on launch when counsel or retailer requires it.

Wholesale access

Approved B2B accounts may request, by SKU and lot:

Lot code + retain-sample policy confirmation
Micro / challenge / stability summary for that SKU family (when commissioned)
Active-ingredient COA packet (formulas remain proprietary — never full formula disclosure)

Email wholesale@tuce.app with company name, SKUs, and lots. Reports are for account diligence — not for republishing as “clinically proven” drug claims.

Honest status

Third-party panels are commissioned per SKU family as production scales. Until a panel is complete for a given SKU, we do not claim that SKU is “lab-certified.” Site language describes the program; lot-level PDFs are the evidence.

Cosmetic / comfort claims only. Oral line is fluoride-free by design. Coconut facial balm is not a sunscreen. See Terms & responsibility and GRC standards.
