A menthol alternative that arrives slowly: L‑menthol bound to citric acid, volatility down more than 90%, no alcohol, low odour. Cooling you can formulate with — plus samples, PhD-led development and OEM/ODM production from the same team.
L‑menthol + citric acid → menthol citrate ester C₁₆H₂₆O₇ · 330.38 g/mol · 2–3.2 g/L in water · volatility down >90%
Ingredient buyers and brand developers need different things from a supplier. Start on the path that matches your brief.
For importers, distributors and in-house R&D teams evaluating a cooling ingredient for an existing formulation.
For brands, startups and buyers who need a finished cooling product developed, formulated and manufactured.
ZPT has been out of EU cosmetics since 1 March 2022. If you are reformulating a scalp line, the front-of-pack claim is the easy part — the active behind it is the decision. Here is what changed.
ZPT-free brief
Free menthol gives you a hit. An ester gives you a curve. In a baby wash, a facial mist or a patch worn for six hours, the curve is the product, and the curve is what we build.
Measured on the ingredient. We characterise the same properties again in your finished formula during development, and the evidence map shows exactly what comes with the material.

View sampleYou start with a sample and a scoped quote. Development is priced before any bench work begins.
Product format, target market, timeline and the claims you intend to make.
We ship a reference sample. You cover shipping and import charges.
Our PhD-led team proposes a development plan with a fixed fee.
Qualifying R&D fees can be credited against future ingredient purchases.
Certification is market-specific, and most of it is issued against a finished product rather than an ingredient. We buy it per project, so the material price carries no share of paperwork you will never use.
The people who answer the technical email run the batches. Synthesis, formulation, analysis and sensory sit in one group, which is why a reformulation question comes back in days rather than as a ticket number.
Development is a fixed fee, quoted before any bench work. Once you buy ingredient at volume, qualifying fees are credited against those orders, so the development fee returns as material credit.
We commission what your destination actually requires — Zone IVb stability, OECD irritation work, a notification package — at cost, quoted per project, with the report going into your file. Every report lands in your file, and only in your price.
Ingredient production happens in our own facility. Finished goods are manufactured through qualified partner factories under our development team's specification.
