Ayu perfume oils are hand blended with attars, essential oils, absolutes, key accords, plant and herb extracts. We use the term "Fragrance" to describe our "proprietary blend" of scent notes that can be found in the description of each scent.  Please note: Certain perfumes contain a very small amount of synthetics. We do this to protect the environment from the over harvesting of endangered plant species. They are listed in the description.  All entirely natural perfumes are also listed as such. All Ayu products are plant based, cruelty free and contain no sulphates, parabens, phthalates, formaldehyde mineral oil or EDTA.
