Abstract
The present invention relates to a benefit agent delivery system that can, when directly applied to a substrate, provide a longer benefit term than when a benefit agent alone is applied to said substrate. Typical benefit agents include perfume raw materials such as perfume aldehydes and ketones.
Claims23
A benefit agent delivery system suitable for delivering a benefit agent to a substrate, wherein the benefit agent delivery system comprises a benefit agent and an amine comprising a primary and/or secondary amine moiety such that when said amine and said benefit agent are directly applied to a substrate, the benefit agent provides a benefit to the substrate for a longer period of time than when said amine is not present.
A benefit agent delivery system comprising
- a.) a benefit agent selected from a perfume aldehyde, perfume ketone and mixtures thereof;
- and
- b.) an amine comprising a primary amine moiety, a secondary amine moiety and mixtures thereof,
- said benefit agent delivery system, when directly applied to a substrate, providing a benefit to the substrate for a longer period of time, as determined by Applicants' Test Protocol 1.1, than when said amine is not present.
A method of applying a benefit agent comprising a perfume aldehyde, perfume ketone and mixtures thereof to a substrate comprising contacting said substrate with said benefit agent before, during or after contacting said with an amine comprising a primary amine moiety, a secondary amine moiety and mixtures thereof.
A benefit agent delivery system comprising
- a.) a benefit agent selected from the group consisting of Alpha Damascone, Delta Damascone, Iso Damascone, Carvone, Gamma-Methyl-lonone, Iso-E-Super, 2,4,4,7-Tetramethyl-oct-6-en-3-one, Benzyl Acetone, Beta Damascone, Damascenone, methyl dihydrojasmonate, methyl cedrylone, hedione, citral, 1-decanal, benzaldehyde, florhydral, 2,4-dimethyl-3-cyclohexen-1-carboxaldehyde;
- cis/trans-3,7-dimethyl-2,6-octadien-1-al;
- heliotropin;
- 2,4,6-trimethyl-3-cyclohexene-1-carboxaldehyde;
- 2,6-nonadienal;
- alpha-n-amyl cinnamic aldehyde, alpha-n-hexyl cinnamic aldehyde, P.T. Bucinal, lyral, cymal, methyl nonyl acetaldehyde, trans-2-nonenal, lilial, trans-2-nonenal, and mixtures thereof;
- and
- b.) a non-aromatic amine having a molecular weight greater than about 50 Daltons and at least about 10% of its amino moieties selected from the group consisting of primary amines, secondary amines and mixtures thereof.
