Made in Thailand

WHERE IT'S MADE

Manufactured inside a research institute at one of Thailand's leading universities.

PrimalBasics is moving every product into the Medical Science Research and Innovation Institute (MSRI), inside Prince of Songkla University in Hat Yai, southern Thailand. PrimalDent was the first product through the transition. The magnesium deodorant's first MSRI batch is scheduled for mid-May 2026. The Bio-Active range — including our flagship Bio Gold serum — and Repel roll through MSRI production between May and August 2026.

This was not the original plan. I started making the first tooth powder on a kitchen counter in Bangkok, and for the first several years of the brand everything we sold was hand-finished by me, in small batches, in a converted workshop. That worked. It did not scale.

In 2025, we made the decision to move production into MSRI. The rollout is staged across 2025–2026, beginning with PrimalDent and continuing through the deodorant, Repel, and the Bio-Active range. The decision was deliberate, and it is, I believe, a material upgrade to our supply chain — more rigorous than almost any clean-luxury peer can claim.

Why a research institute

Prince of Songkla University, founded in 1967, is the first and largest university in southern Thailand. Its Hat Yai campus houses Songklanagarind Hospital — the largest and most specialised general hospital in the region — alongside a network of health-science research facilities, academic laboratories, and regulated production units.

MSRI sits inside that ecosystem. It operates at academic-grade quality standards: documented batch records, calibrated instruments, characterisation and QC on every production run. Every product that leaves the institute has been through ingredient-identity verification, oxidative-stability testing, and microbial screening — discipline that is closer to a pharmaceutical lab than to a typical cosmetic contract manufacturer.

For a brand whose entire positioning rests on the 0% Standard™, that kind of verifiable rigour is what we wanted. That is why we chose to work there.

What this means for you

  1. Every product manufactured at MSRI is Thai FDA notified before it ships. PrimalDent is registered under 90-1-6800016470. The magnesium deodorant's number publishes here in the coming weeks, ahead of its first MSRI batch in mid-May 2026.
  2. Every ingredient used in MSRI-manufactured products has a batch-level certificate of analysis on file. Ask for one and we will send it.
  3. Every product leaves MSRI only after it passes oxidative-stability and microbial testing on the characterisation instruments at the institute.
  4. Nothing about our supply chain is opaque. If you want to know where a specific lipid came from, ask us, and we will tell you.

The partnership, candidly

Most clean-luxury brands outsource to contract manufacturers that specialise in clean beauty — fast, competent, and indistinguishable from the next twenty operations on the same contract-manufacturer floor. We chose the opposite: a research institute inside a university, where the discipline is built around characterisation and documentation rather than marketing claims.

That decision shows up on the label and in the price. It also shows up in the consistency of the product bottle-to-bottle — which, for skincare built on oxidative stability, matters more than the marketing ever will.
