This ester is rarely offered commercially, since its keeping qualities are not very good. But it is manufactured by a few perfume houses for use in fragrance compositions. Smaller amounts are used in flavor compositions. Its main purpose is that of blending with a mild, sweet, buttery or creamy note contributed to the fragrance. This note is often desirable in floral bases and is particularly suitable for Ylang-Ylang. The mellowing effect of this material also depends upon the composition of the fragrance, since the ester is easily hydrolyzed.
Produced from Propylene glycol and Butyric anhydride.
