1. A composition of matter comprising:
35 to 55% w/w of (R,Z)-3-methyl-cyclopentadec-5-en-1-one, having an ee of at least 80%; 27 to 40% w/w of (R,E)-3-methyl-cyclopentadec-5-en-1-one, having an ee of at least 80%; 3 and 20% w/w of (S,E)-3-methyl-cyclopentadec-4-en-1-one, having an ee of at least 80%; and 0 to 5% w/w of (S,Z)-3-methyl-cyclopentadec-4-en-1-one, having an ee of at least 80%; the percentage being relative to the total weight of the composition of matter;and wherein the various constituent are present in specific molar ratio ranges:of [(R,Z)-3-methyl-cyclopentadec-5-en-1-one/(R,E)-3-methyl-cyclopentadec-5-en-1-one] being comprised between 1.6 and 1.0, or between 1.5 and 1.1, or even between 1.4 and 1.2;and/orof [(R,Z)-3-methyl-cyclopentadec-5-en-1-one/(S,E)-3-methyl-cyclopentadec-4-en-1-one] being comprised between 6.0 and 2.5, or even between 4.5 and 3.0.
