- Antiperspirant — Having the property of diminishing, blocking, or regulating sweat secretion by temporarily obstructing skin pores; a substance or cosmetic formula structurally adapted to prevent underarm wetness and unpleasant odors. Unlike a purely deodorizing lotion, an antiperspirant composition acts directly at the level of eccrine glands using aluminum-based compounds.
- Astringency — The property or quality of a substance being astringent; a complex physiological phenomenon characterized by the sensation of dryness, roughness, and contraction of the mucous membranes, especially oral or cutaneous ones. In the sensory analysis of wines and foods, it represents the tactile, non-gustatory property derived from the precipitation of salivary proteins (specifically proline) by polyphenolic compounds.
- Azulene — A bicyclic aromatic hydrocarbon, an isomer of naphthalene, structurally characterized by an intense blue color and a specific aromatic odor. This organic substance occurs naturally in the essential oils of certain medicinal plants, such as chamomile or yarrow, and is recognized and widely used for its anti-inflammatory, antiseptic, and soothing properties in the cosmetic and pharmaceutical industries.
