A packaged fabric refreshening product for refreshening a fabric surface and reducing odor therefrom includes a liquid fabric freshening composition and a spray dispenser for dispensing the liquid fabric freshening composition. The liquid fabric freshening composition includes a liquid carrier and from 1 wt % to 5 wt % of cyclodextrin. The spray dispenser is a manually activated trigger-type spray dispenser, which, upon activation by a single movement of a trigger mechanism, is capable of continuously dispensing the liquid fabric freshening composition for a duration of at least 0.4 seconds. An effective amount of such liquid fabric freshening composition can be sprayed through such manually activated trigger-type spray dispenser onto a fabric surface, such as those on beddings, mattresses, sofas or carpets, which that is substantially planar with a minimal dimension of no less than 0.6 meters.

Methods include disposing a layer of a solution or emulsion having a nanostructure on a surface. The surface further includes a SARS-CoV-2 virus disposed thereon. The nanostructure includes a compound or salt thereof. The compound includes one or more styrene units, one or more N-alkylacrylamide units, and a moiety represented by the formula:

##STR00001##

where R.sup.1 is alkyl. The compound includes a moiety represented by the formula:

##STR00002##

where R.sup.1 is alkyl and R.sup.2 and R.sup.3 are independently hydrogen or alkyl. The compound includes a plurality of N,N-(dialkylamino)(divalent alkyl) alkylacrylate units. One or more of the N,N-(dialkylamino)(divalent alkyl)alkylacrylate units has an unsubstituted nitrogen. One or more of the N,N-(dialkylamino)(divalent alkyl)alkylacrylate units is substituted with a C.sub.1-C.sub.16 alkyl moiety, and one or more of the N,N-(dialkylamino)(divalent alkyl) alkylacrylate units is substituted with a moiety selected from the group consisting of guanidine, polygalactose, coumarin, and combination(s) thereof.

A deodorizing and anti-irritating brassiere is presented. The brassiere includes one or more fabric portions and the fabric portions are made of nylon, polyester, cotton, and polyurethane (e.g., Spandex); these include fabric blends of nylon, polyester, cotton, and polyurethane/Spandex. The brassiere has a deodorizing and anti-irritating coating that includes a deodorizing, bactericidal and fungicidal component of

##STR00001##

wherein m is 2, 3, 4, 5, 6, 7, 8, 9 and a deodorizing component that includes the following compound:

##STR00002##

and a compound according to the following formula (I)

##STR00003##

wherein n is 6, 7, 8; R.sub.1, R.sub.2, and R.sub.3 are jointly or independently selected from H or

CH.sub.2CH.sub.2SO.sub.3.sup.Na.sup.+(II)

wherein the total number of groups represented by formula (II) can be 2, 4.

A method of providing fragrance to a product releasable on exposure of the product to humidity, comprising (a) the encapsulation of fragrance in a particulate matrix by dispersing the fragrance in a solution of the matrix material and spray-drying the dispersion to give fragrance-containing particles; (b) dispersing the particles in an organic liquid non-solvent for the matrix material; and (c) adding the resulting particles to the product.

The particles thus treated do not separate so readily from the product, resulting in a longer-lasting fragrance.

Disclosed are compositions developed for the denaturation of respiratory allergens, such as mite, pollen, feline, canine, mold and fungal allergens. In particular, disclosed are water based compositions of vegetable origin, which prevent allergic reactions in the body by denaturing respiratory allergens before they enter the body through the respiratory tract, while they are still in the environment. Different versions of compositions are disclosed containing at least one acid, at least one herbal essential oil, an anionic surfactant or cyclodextrin, as well as water.
