Notes from formulation work, not from a marketing plan.
Four pieces on the questions that decide whether a cooling ingredient survives a real formula: what the scalp microbiome actually does, why more sensate is not more cooling, how duration is measured, and how to build the spray without alcohol.
Malassezia is on almost every adult scalp. So why does only some of it flake?
Why the target is a balance, not zero yeast — and the six questions that separate real inhibition data from decoration.
Read Cooling systemsWhy adding more cooling agent can make a product feel less cool.
Solubility ceiling, volatilisation, micelle binding and receptor desensitisation — with the 0.2% vs 0.5% data.

Thermal, sensory and release methods, what a duration claim actually needs, and the seven questions to ask a supplier.

Every figure in these articles is traceable.
The chemistry and the microbiology come from a published patent application, CN 121731277 A. The physicochemical values come from in-house characterisation of the grade we ship. The cooling comparison is an internal study.
Where a number is ours, the article says so and the protocol goes out under NDA.
