A household product contains a fragrance composition, in which the fragrance composition contains from about 0.2 to less than 10% by weight of isopulegol, based on the total weight of the fragrance composition. A method for delivering a perceived cooling sensation in the air includes dispersing isopulegol into the air, or implementing the household product as the above.

Household product delivering cooling sensations

The present disclosure provides a fragrance accord comprising a mixture of dihydromyrcene and at least one compound selected from peppermint cyclohexanone, menthol, isopulegol, pulegol, menthyl acetate, and optionally at least one compound selected from citroxide, elemicin, elemol, geranic oxide, vanillyl ethyl ether, vanillyl butyl ether, caryophyllene beta, and zingiberene alpha. Consumer products containing said fragrance accord are also provided herein.

Fragrance composition

A solid composition contains (a) from 30 to 65% by weight of a polyethylene glycol, (b) from 0 to 40% by weight of a C-C-alkyl polyalkoxylate including at least 40 alkoxylate units, (c) from 0.5 to 15% by weight of free fragrance, (d) from 0.1 to 15% by weight of encapsulated fragrance, and (e) from 1 to 35% by weight of an alkaline metal salt, alkaline earth metal salt or salt of an inorganic or C-C-alkyl organic acid, or mixture thereof.

Solid composition comprising free and encapsulated fragrances

A novel microcapsule which is endowed for example with reduced leakage of encapsulated materials. The microcapsule contains one or more fragrances and is suitable for inclusion in non-edible consumer goods products, laundry products, personal care products and cosmetic products. The microcapsule can be obtained in an economic and efficient manner by polymerizing an emulsion so that emulsion droplets are encapsulated into a subsequently cured polymeric shell.

Microcapsules

The present invention relates to core shell microcapsules for use in liquid consumer products, wherein: the microcapsule shell is made of starting materials such that 50%-100% by weight of said materials have a density equal to or less than 1.05 g/cm; the microcapsule core contains a fragrance composition comprising 20-100% by weight of at least one cyclic fragrance material with a density greater than 0.950 g/cmand a ClogP in the range of from 1.00 to 6.00; the weight ratio of core materials to shell materials is in the range from about 50:1 to about 1:1.

Core shell microcapsules and liquid consumer product

The present invention relates to a high intensity fragrance composition for use in a cosmetic, toiletry, personal care, personal cleansing product or adsorbent article, which comprises by weight: a) 75% to 100% of at least 2 fragrance ingredients where each fragrance ingredients must contain only atoms of carbon, hydrogen, oxygen and nitrogen, comprise an ester functional group, an alcohol functional group or an aldehyde functional group, have boiling points between 100&#xb0; C. and 300&#xb0; C. at a pressure of 760 mm of mercury, have molecular weights within the range of 70 atomic mass units to 175 atomic mass units, and have ClogP values between 0.00 and 4.00; b) 0 to 25% of an essential oil; and c) 0 to 25% of a fragrance ingredient other than the fragrance ingredients in category a), wherein the sum of a), b) and c) equals 100%.

High intensity fragrances

The invention relates to a core shell microcapsules containing a fragrance composition which comprises, prior to encapsulation: A) 40 to 100% by weight of at least one cyclic aromachemical material with a density between 0.950 g/cmand 1.500 g/cmand a ClogP value between 1.00 and 6.00; B) 0 to 80% by weight of at least one fragrance material with a density between 0.630 g/cmand 0.950 g/cm; and C) 0 to 50% by weight of at least one oil soluble organic compound having a density between 0.950 g/cmand 1.500 g/cm, where the sum of A), B) and C) equals 100%.

Fragrance composition for core shell microcapsules

A fragrance composition to be incorporated into the core of a core shell capsule, including:

Encapsulation of bulky fragrance molecules

The use of fragrance compositions comprising fragrance compounds selected among: aldehydes, &#x3b1;,&#x3b2;-unsaturated aldehydes, alcohols, ketones, and mixtures thereof in any home and personal care product, each fragrance compound being able to restrict the formation of indole to less than 0.01 ppm (wt/wt) after 24 hours incubation at room temperature in an airtight sealed vessel of suitable fresh human urine containing 0.28% by weight of each fragrance compound in order to prevent the development of indole based malodours from faecal and urine based soils.

Use of fragrance compositions for the prevention of the development of indole base malodours from fecal and urine based soils

The present invention relates to perfumed composition which comprises: a) from 1% to 25% by weight of a fragrance composition; b) from 1% to 10% by weight of at least one nonionic surfactant having at least two hydrophobic chains each containing from 4 to 20 carbon atoms; c) from 1% to 10% by weight of at least one anionic surfactant having at least two hydrophobic chains each containing from 4 to 20 carbon atoms; d) from 1% to 20% by weight of solvent which is a diol having from 4 to 12 carbon atoms, preferably from 4 to 8 carbon atoms, or a mixture of such diols; e) at least 50% by weight of water.

Fragrance microemulsion compositions

The present invention relates to a process for the manufacture of a spray dried powder comprising:

Spray dried powdered detergents with perfume-containing capsules

The invention concerns perfuming and protecting against microbial spoilage products, which are not intended for human or animal ingestion and which comprise at least 25% of water and 0-60% of a surface active material, by incorporating therein a preservative perfume. Preservative perfumes consist for at least 30% by weight of perfume ingredients which need at least 3 inoculations for failure in the individual challenge test. Preferred effective perfumes themselves need at least 5 inoculations for failure in the perfume challenge test.
