Iso E Super (IFF)

Iso E Super is one of the most influential modern aroma chemicals in perfumery, known for its smooth woody, amber-like aroma with subtle velvety and cedarwood nuances. Developed by International Flavors & Fragrances (IFF), Iso E Super is prized for its ability to add radiance, depth, and a soft woody warmth to fragrance compositions.

Unlike many traditional fragrance materials, Iso E Super has a unique transparent quality that enhances other notes while creating a smooth and elegant background. It is widely used by perfumers to improve diffusion and add a modern woody character to perfumes.

Because of its versatility and subtle elegance, Iso E Super is used extensively in fine fragrance, niche perfumes, soaps, candles, detergents, and personal care formulations. It blends beautifully with florals, musks, citrus materials, and amber notes, making it one of the most commonly used ingredients in contemporary perfumery.
