Zusammenfassung: | A method of countering malodour in a washing machine at the end of a wash cycle, comprising the addition thereto of a fragrance precursor. The fragrance precursor may be added alone in solution, or as part of a fabric softener/conditioner. The precursor is particularly ethyl (Z)-2-acetyl-4- methyltridec-2-enoate; ethyl N,S-bis(4-oxo-4-(2,6,6-trimethylcyclohex-3-en-1-yl)butan-2- yl)cysteinate;4-(dodecylthio)-4-methylpentan-2-one; 1-butoxy-3-((1E,4Z)-hepta-1,4-dien-1- yl)benzene;2-ethoxy-4-((1E,4Z)-hepta-1,4-dien-1-yl)phenol; and mixtures thereof. The use of precursor in this manner provides a washing machine that is free from malodour for a prolonged period.
Un método para contrarrestar los malos olores en una lavadora al final de un ciclo de lavado, que comprende la adición de un precursor de fragancia. El precursor de fragancia se puede añadir solo en solución o como parte de un suavizante/acondicionador de telas. El precursor es particularmente (Z)-2-acetil-4-metiltridec- 2-enoato de etilo; N,S-bis(4-oxo-4-(2,6,6-trimetilciclohex-3-en-1- il)butan-2-il)cisteinato de etilo; 4-(dodeciltio)-4-metilpentan-2- ona; 1-butoxi-3-((1E,4Z)-hepta-1,4-dien-1-il)benceno; 2-etoxi-4-((1E,4Z)-hepta-1,4-dien-1-il)fenol; y mezclas de los mismos. El uso del precursor de esta manera proporciona una lavadora que está libre de malos olores durante un período prolongado. |
