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) is disclosed.

Compositions comprising precursors for volatiles

A compound based on 1-Aza-3,7-dioxabicyclo[3.3.0]octane (bicyclic oxazolidine derivative) substituted with 2-phenylpropyl represented by formula (I) is disclosed.

Pro-fragrances and method of preparation thereof

A washing or cleaning agent that has MOFs (metal organic frameworks) in order to reduce offensive odor, a method for reducing malodors, and the use of MOFs to reduce malodors.

Washing or cleaning agent for reducing malodors

Photolabile pro-fragrances may include the ketones of Formula (I)  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.

Photolabile pro-fragrances

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.

The invention relates to specific ketones of formula (I) which act as photolabile pro-fragrances. The invention also relates to detergents or cleaning agents, cosmetic agents and air fresheners including such ketones. The invention further relates to a method for creating a long-lasting fragrance on surfaces and also to a method for creating a long-lasting fragrance in a room using the aforementioned ketones.

The disclosure relates to special orthoformic acid esters of formula (I), as defined herein, which can be used as thermally labile and acid-labile fragrance storage substances. The disclosure further relates to detergents and cleaning agents, cosmetic agents and air freshening products containing such orthoformic acid esters, as well as to a method for lastingly fragrancing surfaces.

Orthoformic acid esters as pro-fragrances

The invention relates to specific ketones of formula (I) which act as photolabile pro-fragrances. The invention further relates to detergents or cleaning agents, cosmetic agents and air freshening products including ketones of said type. The invention also relates to a method for lastingly scenting surfaces and a method for lastingly fragrancing rooms using said ketones.

Fragrances having a fresh character are usually very volatile and therefore not very economical in typical applications such as washing or cleaning processes for example. For that reason they have to be used in relatively large amounts in order to bring about appropriate effects. The present invention describes photolabile pro-fragrances of formula (I) that allow for a greatly improved persistence of the fragrance impression, in particular one having a fresh character, in typical applications. Said pro-fragrances attach very readily to target substrates, such as textiles for example. A more economical use of the fragrances in question can be ensured in this way. 

The invention describes a method for degrading off-odors by employing a special 1-aza-3,7-dioxabicyclo[3.3.0]octane compound. Degradation of off-odors to the point of extinction of the off-odor, on hard and/or soft surfaces, in particular on textiles, and in room air, is made possible.

Process for controlling malodors using oxazolidines

Stable formulations and perfume compositions include amino alcohol(s) as well as &#x3e;10 wt % fragrances.

Stabilized perfume oils

Fragrances that provide a scent of freshness tend to be volatile and are therefore not very economical when used in typical applications such as washing or cleaning processes, so they have to be used in relatively large quantities to be able to produce adequate effects. The disclosed photolabile pro-fragrances provide a much longer-lasting sense of fragrance, in particular with a scent of freshness, when used in typical applications, thus allowing said fragrances to be used economically.

The present invention relates to a method for producing photocleavable scent precursors, to products containing the scent precursors, and to the use of the scent precursors for prolonging the scent impression in the product and on surfaces treated with the product.

The invention relates to a composition of (a) a selected amino alcohol compound of general formula (I), (b) a scent aldehyde and/or scent ketone, and (c) a selected silicic acid ester, to the use of same as a pro-scent, as well as to washing and cleaning agents, fabric softeners and cosmetics which contain these. The invention also relates to a method for prolonging the perception of scent in such agents, and to a method for removing malodors by applying said composition. 

Combination of an amino alcohol, a fragrance and a silicic acid ester, and the use of same as a pro-fragrance

Many fragrances that provide a scent of freshness tend to be highly volatile and are therefore not very economical when used in typical applications such as washing or cleaning processes, so they have to be used in relatively large quantities to be able to produce adequate effects. The disclosed photolabile pro-fragrances provide a much longer-lasting sense of fragrance, in particular with a scent of freshness, when used in typical applications, thus allowing said fragrances to be used efficiently.
