pH、ミント、刺激感
Sensation depends on pH, free nicotine, moisture, pouch material, salt, flavour and contact time.
pH & free-base nicotine
Higher pH usually increases free-base nicotine and can increase buccal absorption, but pH alone does not determine sensation.
Mint, menthol & cooling agents
Menthol activates receptors including TRPM8. Low concentrations may cool; higher concentrations can irritate or burn.
