Fragrance, often referred to as perfume or scent, is a complex mixture of various aromatic compounds, essential oils and synthetic chemicals carefully blended to create a pleasant and unique scent. These scents are widely used in cosmetic and personal care products like perfumes, colognes, soaps, creams and lotions, to improve the sensory experience and leave a pleasing scent on skin or hair. Fragrance can evoke emotions, memories and moods, making it a powerful and integral component of many consumer products. But, because the specific ingredients used in fragrance formulas are generally proprietary and considered trade secrets, they are often listed on product labels simply as "Fragrance" or "Parfum."
