A detergent, cleaning, fabric softener or cosmetic composition comprising a compound based on 1-Aza-3,7-dioxabicyclo[3.3.0]octane (bicyclic oxazolidine derivative) substituted with 3,7-dimethyl-1,6-nonyldien represented by formula (I)

##STR00001##

is disclosed.

The present invention relates to an active substance wafer and methods for producing such an active substance wafer. Further, the present invention relates to the use of such an active substance wafer as/in a laundry care agent, a hand laundry washing agent or a dishwashing agent and to a product selected from these agents consisting or comprising an active substance wafer.

The present application relates to perfume delivery systems and consumer products comprising a novel organoleptic compound and or perfume delivery systems having the novel organoleptic compound, as well as methods for using such perfume delivery systems and consumer products.

A method for reducing water consumption in a toilet system comprises adding a water-soluble pellet to the toilet bowl prior to or following use of said toilet for urination, the pellet comprising a colourant and a fragrance for masking the colour and odour of urine residing in the toilet bowl, and preferably also disintegrant and/or an effervescent system that effervesces on contact with water, and refraining from flushing said toilet until after said toilet has been used at least one further time. The use of such water-soluble pellets serves to reduce the perceived need to flush the toilet after every use and drives positive change against wasteful water usage. The pellets are small, for example 8 mm or less in diameter and weigh 0.1-0.3 g, and can be stored in a re-sealable, refillable, reusable dispenser for personal or larger scale use. The method also serves to reduce carbon emissions and chemical usage arising from treatment of fresh and waste water.

A precursor compound of a fragrant aldehyde is provided, as well as a method of forming such a compound, a kit comprising said compound, and certain uses thereof. The precursor compound has formula (I),

##STR00001##

wherein A is a hydrocarbon residue of a fragrant aldehyde A-CHO; and X and Y are independently selected from the group consisting of a nitrile, a keto, and an ester functional group. One such precursor compound is ethyl 2-acetyl-4-methyltridec-2-enoate enriched in its Z-isomer, which is a thermally stable precursor of 2-methyl undecanal.

Photolabile pro-fragrances may include the ketones of Formula (I) ##STR00001## Such compounds may be used in detergents, cleaning agents, cosmetic agents, air-care agents, and combinations thereof. The photolabile pro-fragrances may create a long-lasting fragrance on surfaces or in a room using the aforementioned pro-fragrances.

Cleavable surfactants of formula (I)

##STR00001##

having a total hydrophilic-lipophilic balance (HLB) of between 3 and 18 and wherein A is a group capable of releasing a flavor or fragrance aldehyde of formula (R.sup.1)CHO or a flavor or fragrance ketone of formula (R.sup.1)(R.sup.2)CO and is of formula

##STR00002##

wherein the wavy line indicates the location of the bond between L and A; R.sup.1 and R.sup.2 represent a hydrogen atom or a saturated or unsaturated C.sub.1-C.sub.18 hydrocarbon group, provided that at least one of the R.sup.1 or R.sup.2 groups has 6 consecutive carbon atoms and that both R.sup.1 and R.sup.2 taken together comprise a maximum of 18 carbon atoms; and L is a linear, branched or cyclic, saturated or unsaturated C.sub.3 to C.sub.40 hydrocarbon group. These surfactants solubilize and/or stabilize flavor and fragrance aldehydes and ketones in an aqueous environment and at the same time to control their release by hydrolysis.

Disclosed is a continuous method for producing perfume-containing melting bodies which include at least one water-soluble or water-dispersible carrier polymer having a melting point>30 C. to 250 C. and at least one aromatic substance. The method contains the following steps: continuous supply, optionally continuous production and supply, of a melt having the at least one water-soluble or water-dispersible carrier polymer; continuous addition of the at least one aromatic substance to the melt-having the at least one water-soluble or water-dispersible carrier polymer; mixing the melt having the at least one water-soluble or water-dispersible carrier polymer and the at least one aromatic substance; and cooling the mixture in order to produce perfume-containing melting bodies. Also disclosed is perfume-containing melting bodies produced in this way.

The present invention relates to the field of perfumery. More particularly, it concerns co-polymers, derived from aspartic acid and comprising at least one - or -aspartic acid derivative capable of liberating an active molecule such as, for example, an ,-unsaturated ketone or aldehyde. The present invention concerns also the use of polymers or co-polymers in perfumery as part of a perfuming or malodor counteracting composition, as well as the perfuming compositions or perfumed articles comprising the invention's compounds.

Photolabile scent storage substance that are capable of photoinduced release of cyclic compounds have at least one cyclic double bond. These scent storage substances are special ketones, and enable greatly improved stability of the scent impression, in particular with a fresh character, in typical applications, for example in textile laundering, room scenting, and in the cosmetic sector. More economical utilization of the stored scents can thereby be ensured. Also described are corresponding washing or cleaning agents, scenting methods, and methods for manufacturing the special ketones.
