Claims9
A perfume composition comprising:
- one or more fragrance compounds selected from the group of compound classes consisting of terpenoids, pyrocatechol derivatives, phenol derivatives, aromatics, aliphatics, alicycles, and heterocycles;
- amino alcohol(s) according to the formula (II)
- wherein R1, R2, and R3 in formula (II), mutually independently in each case, denote hydrogen or hydrocarbon residues, or hydroxyalkyl residues in which the hydrocarbon or hydroxyalkyl residues are optionally substituted;
- and
- optionally one or more solvents selected from the group consisting of benzyl alcohol, dipropylene glycol, Dowanol, ethanol, isopropanol, isopropyl myristate, paraffin, propylene glycol, castor oil, and triazine,
- wherein the fragrance compound(s) and amino alcohol(s) constitute at least 50 wt. % of the perfume composition.

A method for stabilizing one or more fragrance compounds, comprising
- adding amino alcohol(s) according to the formula (III)
- wherein R1, R2, and R3 in formula (I), mutually independently in each case, denote hydrogen or hydrocarbon residues, or hydroxyalkyl residues in which the hydrocarbon or hydroxyalkyl residues are optionally substituted to a perfume composition comprising one or more fragrance compounds selected from the group of compound classes consisting of terpenoids, pyrocatechol derivatives, phenol derivatives, aromatics, aliphatics, alicycles, and heterocycles,
- wherein the perfume composition optionally comprises one or more solvents selected from the group consisting of benzyl alcohol, dipropylene glycol, Dowanol, ethanol, isopropanol, isopropyl myristate, paraffin, propylene glycol, castor oil, and triazine, and
- wherein the fragrance compound(s) and amino alcohol(s) constitute at least 50 wt. % of the perfume composition.
