designed for longevity, in every sense.
A young brand with three products and no certifications. Here is what is actually true about how Tideline is made — and, at more length than most brands manage, what we are not claiming.
the commitments
two things we do. one we don’t.
- 01
made in north america, cruelty-free
The three formulas are produced by our manufacturing partner in North America, cruelty-free and paraben-free. The full INCI list sits on each product page, in order, unabridged — including the ingredients that are unglamorous. The Rose Gold Oil is vegan; the Shea Body Butter contains beeswax and so is not, and we say so on the page rather than leaving it to be discovered.
- 02
recyclable packaging, no take-back yet
The primary packaging is recyclable through ordinary kerbside streams. What we do not have is a take-back scheme: no pre-paid empties label, no closed-loop partner, no refill pouch. Building one for a three-product line at our volume would cost more in freight emissions than it saves in material, and we would rather say that plainly than launch a programme whose main output is a badge.
- 03
what we do not claim
We are not a member of 1% for the Planet. We are not Climate Neutral Certified. We do not purchase carbon offsets, and no third party audits our numbers, because there is not yet an operation large enough to audit. Tideline launched in 2026 and sells three products. Any of these can become true later — and if one does, it will arrive here with a date and a link to the certificate. Until then the honest answer is the short one.
the thinking behind it
the cheapest sustainability claim is the one you don’t make.
An earlier version of this page said a great deal more. It described refill pouches in slim aluminium, production cohorts of eight hundred to twelve hundred bottles, carbon offset at one-and-a-half times the calculated footprint, a 1% for the Planet line on the income statement, and an annual third-party audit with the results published. It read well. None of it was true, and some of it named certification marks that belong to organisations we have never applied to.
We took it down rather than quietly softening the wording, because softening it would have kept the impression while removing the liability, and the impression was the dishonest part. What is left is short: made in North America, cruelty-free, recyclable packaging, full ingredient lists in the open. If a buyer chooses a competitor over that, they have chosen on accurate information, which is the only version of the choice worth winning.
