Formulated in Bangkok · Manufactured in Thailand

At 49, I weighed 280 pounds. I couldn't find personal care products I trusted, so I started making my own.

PrimalBasics is founder-formulated personal care, held to The 0% Standard™ — fourteen non-negotiable exclusions across every formula. Mike formulates every product in Bangkok. Manufacturing partner: the Medical Science Research and Innovation Institute (MSRI) at Prince of Songkla University, southern Thailand.

If you've never tried a PrimalBasics product, start with the tooth powder.

Four ingredients. Made by Mike for himself in 2018. The first PrimalBasics product, still formulated the same way. THB 490 a jar — six weeks of twice-daily use. The first morning you brush with it, you'll understand what we mean by different.

THE 0% STANDARD™

What we don't include is as specific as what we do.

We publish everything we exclude — and we hold that standard across every product, every batch, every formulation we have ever made. The list below is divided into universal exclusions (in every product) and category-specific exclusions (where the chemistry makes them relevant). It is enforceable, verifiable on the label, and it is the one thing we do not compromise on.

Universal — in every PrimalBasics product:
0% industrial seed oils · 0% synthetic fragrance · 0% hexane · 0% phthalates · 0% parabens · 0% triclosan · 0% sodium lauryl sulfate · 0% propylene glycol · 0% silicones · 0% petroleum derivatives
Category-specific — where chemistry makes them relevant:
0% aluminium (deodorant) · 0% baking soda (deodorant) · 0% fluoride (oral care) · 0% DEET (insect repellent)

Our manufacturing partner is a research institute, not a private factory.

  • A research institute, not a private factory.

    The Medical Science Research and Innovation Institute (MSRI) sits inside Prince of Songkla University — one of Thailand's top-tier research universities, with recognised programmes in natural products, cosmetic chemistry, and tropical medicine.

  • Academic-grade quality protocols.

    Documented batch records, calibrated instruments, and ingredient-identity verification on every production run. The discipline of a university research institute — closer to a pharmaceutical lab than a typical cosmetic contract manufacturer.

  • A verifiable supply chain.

    Every batch is traceable. Every ingredient has a certificate of analysis on file. Every product manufactured at MSRI is Thai FDA notified before it ships. If you want to know where a specific lipid came from, ask — we will tell you.
