Usage
Use (Hekserij)
Methyl tuberate (Giv) has a waxy floral scent reminiscent of aspects of flowers
such as tuberose, gardenia and tulip. The scent is not particularly strong, but
a low dosage is common. Making a dilution of for example 10% in TEC or DPG can
therefore be useful. Typical use is in floral accords, especially tuberose and
gardenia. You usually use between 0,1% and 1% of this substance in the fragrance
composition. It combines well with lactones and coconut-like scents. It adds a
natural extra dimension to the scent. In perfumes it is mainly a base note. It
is stable in many products, also in soap, but it cannot withstand a very high or
low pH or bleach.

Properties (Hekserij)
Methyl tuberate (Giv) is a colourless to light yellow liquid at room
temperature. The purity is at least 95% (four isomers) and the substance has a
fairly long shelf life. It occurs in nature, but for use as a fragrance the
synthetic version is used. This is largely based on synthetic raw materials. The
manufacturer is the Swiss Givaudan, they call this substance Methyl Tuberate
Pure.
