RAUPYAM LABS · OPEN ANALYTICAL WORK
Open Lab
Most beauty brands ask you to trust a number. We are not even selling yet — and we are already doing the work to earn it.
When we do put a bottle on a shelf, it will claim a percentage — 1.5% salicylic acid, say. Most brands print that number straight off a supplier's certificate and never measure it themselves. We decided that before we sell anything, we would learn to measure it ourselves — properly, and in public.
So this is the work, published as we do it: the methods, the mistakes, the chromatograms, the decisions. Not a polished summary — the actual bench record, including where it went wrong. Because a result you cannot inspect is not evidence; it is a claim wearing a lab coat. We would rather show you the work now than ask for your trust later.
Raw Material Files record what we buy and whether it is real. Open Lab records how we measure it. When products ship, batch reports will record what is actually in the bottle.
What’s in the other 5%: ferulic acid
Nobody sells you a pure ingredient. How ferulic acid is made, what that process leaves behind, and what we can — and cannot yet — prove about ours.

Two decisions changed our UPLC assay — one about pH, one about wavelength. Both taught us the difference between what a chromatogram shows and what a spec sheet claims.
