Ambrostar

About Ambrostar

Ambrostar is a synthetic aroma ingredient supplied by Symrise. The manufacturer classifies it as an acetal and identifies it with CAS number 1357064-95-9. Its appearance is a clear to pale yellow liquid. It is a perfumery material with an amber character, rather than an extract of fossil amber or a natural resin.

Scent Profile

Its main character combines warm amber and wood with a soft animalic aspect. Symrise describes a powerful, persistent base note whose woody-ambery texture remains warm and gentle. The impression has more rounded depth than a simple dry-wood effect, allowing it to sit behind brighter materials and give a composition a substantial foundation. The animalic facet is part of its aromatic profile and does not describe an animal-derived raw material.

Use in Perfumery

Ambrostar can support woody-amber bases and reinforce the distinctive character of oud notes. Its versatility makes it useful across different fragrance styles, with the surrounding flowers, spices or woods shaping how its warmth appears. A small amount can already make a noticeable contribution, so its role is often structural as well as recognisably ambery. The finished perfume’s projection and duration depend on the whole formula and cannot be inferred from this ingredient alone.
