Abstract
Disclosed herein are pro-perfume compositions comprising the Michael Addition reaction product of a primary and/or secondary amine compound with an unsaturated ester, acid or nitrile perfume compound. Pro-perfumes made from this selected type of reaction product provide a desirable and prolonged odor benefit to surfaces, e.g., fabrics and hard surfaces, contacted therewith. Such pro-perfumes are also utilized in a wide variety of substrate-treating products and methods.
Claims19
A pro-perfume composition suitable for incorporation into cleaning or fabric treatment products, which composition comprises the reaction product of a primary and/or secondary amine compound with an unsaturated perfume compound of the formula:
- 2
- wherein R1 is CN, COOH or COOR, with R being an organic moiety containing no aldehyde or ketone functionalities;
- and R2, R3 and R4 each independently being organic moieties which, together with R1, render the resulting compound a material having perfume characteristics;
- and wherein said amine compound is selected so as to provide the resulting reaction product in the form of a viscous fluid having a viscosity ranging from about 500 to 100,000,000 centipoise.
A pro-perfume composition suitable for incorporation into cleaning or fabric treatment products, which composition comprises the Michael Addition reaction product of
- A) an amine compound selected from polyethyleneimines having a molecular weight greater than about 200 daltons, amine-derivatized silicones and polylysine;
- with
- B) an ester perfume compound having an unsaturated double bond in conjugation with an electron withdrawing group;
