Patchoulol Crystals PA99 is a high-purity isolate derived from patchouli oil, specifically containing the key aromatic compound patchoulol, which is responsible for the characteristic earthy and woody scent of patchouli. In perfumery, it is valued for its rich, deep, and complex aroma, often used to impart a sense of warmth and depth to compositions. Patchoulol is commonly found in oriental and woody fragrance families, where it can serve as a base note, providing longevity and a solid foundation for other ingredients. Its versatility allows it to be blended with a variety of other notes, enhancing floral, fruity, and spicy accords. From a safety and regulatory perspective, patchoulol is recognized as a potential allergen, and its use is subject to IFRA guidelines, which may impose restrictions based on concentration levels in finished products. As with many fragrance materials, it is essential for formulators to consider these regulations to ensure compliance and safety in cosmetic applications. — AI-generated summary, 2026-09-02.
