Fraistone PFG BHT (I)
Tart, Fresh, Fruity, Apple, Strawberry, Plum, Liquorice, Anisic nuances
About this material
Fraistone PFG BHT by International Flavours & Fragrances (IFF) is a sophisticated synthetic ketal acclaimed in perfumery for its fresh, tart and delicately fruity character.
With evocative top notes reminiscent of crisp apples, ripe strawberries and subtle plum facets, Fraistone infuses compositions with a lively and memorable fruitiness that enhances both modern and classic floral accords.
This ingredient’s inherent freshness makes it ideal for citrus-fruity opening notes in fine fragrances, sparkling accords, and nuanced gourmand highlights when used with complementary synthetics.
Its medium odour strength allows it to shine in trace amounts yet remain elegant and balanced even at higher usage levels.
Fraistone’s chemical structure provides it with excellent miscibility in alcohol and common fragrance bases.
Stabilised with BHT (Butylated Hydroxytoluene) for extended shelf life and oxidative resistance, this ingredient ensures durability of both formula character and quality during storage and maturation.
Whether used to elevate fruity signatures or to add a refined brightness to florals and green notes, Fraistone PFG BHT stands as a premium choice for perfumers seeking clarity, freshness and refined olfactory depth.

Creative ideas to explore
Creative directions, not tested formulas.Fruit with its peel
With citrus and leafy contrastsExplore a fruit sketch that includes a suggestion of peel or leaf. Compare those accents separately against the fruity reference, noticing whether they create a fresher impression or pull the idea away from the fruit you imagined.
An orchard in bloom
With rose or another familiar flowerPlace the fruity direction beside a simple floral accord. Keep a flower-only comparison and assess whether the fruit reads as a supporting accent, a juicy centre or a separate note that needs a different setting.
Fruit and cream
With vanilla and soft wood directionsSketch a more rounded fruit idea with vanilla as one variation and soft wood as another. Compare sweetness and texture before combining both, leaving room for the original fruity character to remain identifiable in the study.
