Abstract

The present disclosure is directed to an encapsulated fragrance composition including an accord including at least one of menthol and isopulegol. Consumer products containing said encapsulated fragrance composition are also disclosed herein.

First claim

The invention claimed is:

1. A laundry product comprising a fragrance composition encapsulated in core-shell capsules, wherein the fragrance composition comprises from about 1.00 wt % to about 10.00 wt %, based on the weight of the fragrance composition, of an accord, wherein the accord comprises:
(i) from about 90.00 wt % to about 99.99 wt %, based on the weight of the accord, of at least one compound selected from the group consisting of menthol, menthyl acetate, isopulegol, pulegone, pulegol, peppermint cyclohexanone, dihydromyrcene and combinations thereof;
(ii) from about 0.01 wt % to about 10.00 wt %, based on the weight of the accord, of at least one compound selected from the group consisting of citroxide, elemicin, elemol, geranic oxide, vanillyl ethyl ether, vanillyl butyl ether, caryophyllene beta, zingiberene alpha and combinations thereof;
wherein the accord comprises at least two compounds,
wherein at least one of menthol and isopulegol is present in the accord; and
wherein the sum of (i)+(ii) makes up 100 wt % of the accord.

2. A laundry product comprising a fragrance composition encapsulated in core-shell capsules, wherein the fragrance composition comprises from about 1.00 wt % to about 10.00 wt %, based on the weight of the fragrance composition, of an accord, wherein the accord consists of menthol, isopulegol and citroxide;
wherein menthol and isopulegol make up from about 90.00 wt % to about 99.99 wt % of the accord and citroxide makes up from about 0.01 wt % to about 10.00 wt % of the accord.

3. The laundry product of claim 1 , wherein the accord comprises menthol and menthol represents at least 40.00 wt % of the combined weight of all compounds (i) in the accord.

12. The laundry product of claim 1 , wherein the laundry product is selected from the group consisting of a laundry detergent, a fabric softener and a fabric conditioner.

13. The laundry product of claim 2 , wherein the weight ratio between menthol and isopulegol is in the range from about 30:70 to about 70:30.

14. The laundry product of claim 2 , wherein the shell of the core shell capsules comprises a material selected from the group consisting of: polyolefins, polyamides, polystyrenes, polyisoprenes, polycarbonates, polyesters, polyacrylates, aminoplasts, polysaccharides, gelatine, shellac, epoxy resins, vinyl polymers, water insoluble inorganics, silicone, and mixtures thereof.

15. The laundry product of claim 14 , wherein the shell comprises melamine formaldehyde and/or cross-linked melamine formaldehyde.
