Technical Field

The present invention relates to compositions for reducing odor and freshening odors in air applications.

Background

In recent years, the field of air care with fragrances has been one of the fastest growing market areas. Consumers are increasingly seeking air care products that help maintain a clean and fresh atmosphere in the various rooms of their premises. There are many different types of air care products, which are mainly related to the fact that: there are many different types of off-flavours that need to be addressed. Ranging from typical air kitchen odors (air kitchen odor), odors in the living room (in the air or in carpeting and wallpaper), to odors in the bathroom.

While the typical use of these air care products is in the home, there is also a need for products that are effective in out-of-home applications (e.g., industrial, restaurant and hospital kitchens; offices; industrial, restaurant and hospital bathrooms; portable toilets; public and private vehicles; sporting facilities; and waste management).

The main sub-categories of these air care products are scented candles, scented wax melts, gels, passive air fresheners, active air fresheners, as well as aerosol and non-aerosol sprays. Manufacturers of products for controlling/reducing off-flavors often utilize off-flavor reducing ingredients that are effective in reducing off-flavors, but not necessarily eliminating off-flavors. In many products, scented perfumes are used to help mask off-notes, however off-notes may still be present and become apparent again after the efficacy of the scented perfume has faded. These perfumes are therefore enhanced by the odour active ingredient and/or certain common perfume ingredients also play a functional role in the final product.

Detailed Description

In the following description, reference is made to specific aspects that may be practiced, which are shown by way of example. These aspects are described in detail to enable those skilled in the art to practice the invention described herein, and it is to be understood that other aspects may be utilized and that logical changes may be made without departing from the scope of the technical solutions presented herein. The following description of exemplary aspects is, therefore, not to be taken in a limiting sense, and the scope of the various aspects set forth herein is defined by the appended claims.

The abstract is provided to satisfy 37c.f.r. § 1.72(b) to enable the reader to quickly ascertain the nature and gist of the technical disclosure. The abstract is submitted with the understanding that: it is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

For the purposes of this disclosure, the terms "alkyl" and "hydrocarbon" when used alone or as another groupBy partially is meant containing 1 to 12 carbon atoms (i.e., C)_1-12Alkyl) or a specified number of carbon atoms (i.e., C)₁Alkyl radicals such as methyl, C₂Alkyl radicals such as ethyl, C₃Alkyl such as propyl or isopropyl, etc.) straight or branched chain aliphatic hydrocarbons.

For the purposes of this disclosure, the term "amino" or "amine" when used alone or as part of another group refers to — NH₂。

Some of the compounds disclosed herein may contain one or more asymmetric centers and thus give rise to enantiomers, diastereomers, and other stereoisomeric forms. The present disclosure is intended to encompass the use of all such possible forms as well as their racemic and resolved forms and mixtures thereof. The individual enantiomers may be separated according to methods known in the art with reference to the present disclosure. When a compound described herein contains an olefinic double bond or other geometric asymmetric center, it is intended to include both E and Z geometric isomers unless otherwise specified. All tautomers are also intended to be encompassed by the present disclosure.

As used herein, the term "stereoisomer" is a collective term for all isomers of individual molecules that differ only in the orientation of their atoms in space. It encompasses enantiomers as well as isomers of compounds with more than one chiral center that are not mirror images of each other (diastereomers).

The term "chiral center" refers to a carbon atom to which four different groups are attached.

The terms "enantiomer" and "enantiomeric" refer to a molecule that is not superposed on its mirror image and therefore optically active, wherein the enantiomer rotates the plane of polarized light into one direction, and the mirror image compound rotates the plane of polarized light into the opposite direction.

The term "racemic" refers to a mixture of equal parts of enantiomers which is not optically active.

As used herein, the term "about," when used in relation to a measured quantity, refers to the normal variation in the measured quantity as would be expected by a technician making the measurement and performing maintenance at a level commensurate with the purpose of the measurement and the accuracy of the measurement apparatus.

Some aspects relate to compositions for reducing odor in air care applications comprising an odor reducing component and a freshening fragrance component.

In some aspects, the odor-reducing component comprises n-dodecyl methacrylate (lauryl methacrylate). Lauryl methacrylate is typically used as part of a polymeric or copolymeric composition (e.g., poly (lauryl methacrylate) in detergents). In the disclosed aspects, lauryl methacrylate is used in its monomeric form to reduce off-flavors.

In some aspects, the freshening fragrance component comprises one or more fragrance compounds, which may comprise a mixture of volatile aldehydes, esters, ketones, alcohols, hydrocarbons, lactones, and nitriles. It is known that volatile aldehydes can neutralize odors in the vapor and/or liquid phases via chemical reactions. Volatile aldehydes can react with amine odors, which in turn is the schiff base formation pathway. Volatile aldehydes may also react with sulfur-based odors, forming thiol acetals, hemithiol acetals, and thioesters in the vapor and/or liquid phase. Alcohols can chemically react with aldehydes having an odor. In addition, many aldehydes and other scented materials are also powerful odorants that help mask odorous components and thus help freshen room air through the use of corresponding air care products.
