Abstract

Claims (31)

1 . A delivery system comprising a biodegradable carrier and a perfume formulation, wherein the carrier has a biodegradability of at least 60% within 60 days according to OECD301F,

wherein the perfume formulation comprises a perfume oil having the following characteristics:

at least 35% of perfuming ingredients having a log P above 3,

at least 20% of Bulky materials including one or more of:

perfuming ingredients comprising a cyclohexane, cyclohexene, cyclohexanone, or cyclohexenone ring substituted with at least 1 to 4 nodes comprising substituent,

perfuming ingredients comprising a cyclopentane, cyclopentene, cyclopentanone, or cyclopentenone ring substituted with 4 or more nodes comprising substituent,

perfuming ingredients comprising a phenyl ring or perfuming ingredients comprising a cyclohexane, cyclohexene, cyclohexanone, or cyclohexenone ring substituted with 5 or more nodes comprising substituent,

perfuming ingredients comprising at least two fused or linked 5 membered or 6 membered rings,

perfuming ingredients comprising a camphor-like ring structure, or

perfuming ingredients comprising at least one 7 to 20 membered ring; and

at least 15% of high impact perfume materials having a Log T<−4.

2 . The delivery system according to claim 1 , wherein the perfume formulation comprises

0 to 60 wt. % of a hydrophobic solvent, based on the total weight of the perfume formulation,

40 to 100 wt. % of a perfume oil, on the total weight of the perfume formulation, and

optionally, other active ingredients.

3 . The delivery system according to claim 2 , wherein the perfume oil and the hydrophobic solvent have at least two Hansen solubility parameters selected from a first group consisting of: an atomic dispersion force (δD) from 12 to 20, a dipole moment (δP) from 1 to 8, and a hydrogen bonding (δH) from 2.5 to 11.

4 . The delivery system according to claim 3 , wherein the perfume oil and the hydrophobic solvent have at least two Hansen solubility parameters selected from a second group consisting of: an atomic dispersion force (δD) from 14 to 20, a dipole moment (δP) from 1 to 7, and a hydrogen bonding (δH) from 4 to 11.

5 . The delivery system according to claim 1 , wherein the biodegradable carrier is a biodegradable shell or a biodegradable polymeric carrier matrix.

6 . The delivery system according to claim 1 , wherein the delivery system has a biodegradability of at least 40% within 60 days according to OECD301F.

7 . Perfuming composition comprising:

a delivery system according to claim 1 , and

optionally, a free perfume oil.

8 . The perfuming composition according to claim 7 , wherein the total amount of the delivery system is 0.05 to 5 wt. %, based on the total perfuming composition, and the total amount of the free perfume oil is 0.05 to 5 wt. %, based on the total perfuming composition.

9 . The perfuming composition according to claim 7 , wherein a total perfume oil of the perfume formulation entrapped in the delivery system and total free perfume oil are present in the perfuming composition in a weight ratio of 1:20 to 20:1.

10 . Perfumed consumer product comprising the delivery system according to claim 1 .

11 . The consumer product according to claim 10 , wherein the perfumed consumer product is a fine perfume, a splash or eau de perfume, a cologne, a shave or after-shave lotion, a liquid or solid detergent, a mono or multi chamber unidose detergent, a fabric softener, a fabric refresher, liquid or solid scent-boosters, a dryer sheet, an ironing water, a paper, a bleach, a carpet cleaners, curtain-care products, a shampoo, a coloring preparation, a color care product, a hair shaping product, a dental care product, a disinfectant, an intimate care product, a hair spray, a hair conditioning product, a vanishing cream, a deodorant or antiperspirant, hair remover, tanning or sun product, nail products, skin cleansing, a makeup, a perfumed soap, shower or bath mousse, oil or gel, or a foot/hand care products, a hygiene product, an air freshener, a “ready to use” powdered air freshener, a mold remover, furnisher care, wipe, a dish detergent or hard-surface detergent, a leather care product, or a car care product.

12 . The perfumed consumer product according to claim 10 , wherein the perfumed consumer product is a liquid or solid detergent, a mono or multi chamber unidose detergent, a fabric softener, liquid or solid scent-boosters, a dryer sheet, a shampoo, a shower gel, a hair conditioning product, or a deodorant or antiperspirant.

13 . The delivery system according to claim 1 , wherein the carrier has a biodegradability of at least 80% within 60 days.

14 . The delivery system according to claim 7 , wherein the biodegradable carrier is a biodegradable shell.

15 . The perfuming composition according to claim 9 , wherein the total perfume oil of the perfume formulation entrapped in the delivery system and total free perfume oil are present in the perfuming composition in a weight ratio of 10:1 to 1:10.

16 . Perfumed consumer product comprising the perfuming composition according to claim 7 .
