Properties and stability

Colorless to light yellow liquid. It has a powdery, sweet floral and sweet musky aroma. Insoluble in water, soluble in ethanol.
Not found in nature.

Storage method

None yet

Synthesis method

Heating tridecanedioic acid and ethylene glycol to above 200°C turns into cyclic polyester. Add the catalyst and heat to above 270°C under reduced pressure of 0.133 kPa to distill out the macrocyclic monomer.

Purpose

Its low price can harmonize with a variety of fragrances. Because of its stable properties and non-discoloration, it can be used as a fixative for a variety of cosmetic fragrances. Product quality: ester content ≥98%.
