👉 Mint fluid, commonly used as a natural preservative and flavoring agent, is an extract derived from the leaves of the mint plant, typically spearmint. It contains essential oils rich in menthol and menthone, which provide a refreshing, cooling sensation upon contact with the skin or mucous membranes. Historically used for centuries in perfumes, cosmetics, and medicinal applications, mint fluid is valued for its ability to mask unpleasant odors, soothe sore throats, and add a fresh, invigorating aroma. Due to its natural origin and biodegradability, it is often preferred over synthetic alternatives in the formulation of personal care products and food additives.
