The present invention relates to a composition comprising at least one fragrance ingredient, one or more solvents and water, a method for obtaining such a composition in the form of a homogeneous composition, and to the use of such a composition to release a fragrance in an atmosphere in a controlled way.

An aqueous dispersion, an aqueous coating composition comprising the aqueous dispersion, and coatings made therefrom capable of slow release of fragrance.

A sterilization challenge device for verifying the efficacy of a gas sterilization process includes an outer container, an inner container, a chemical indicator, and a cap. The outer container includes an open end, a closed end, a chamber configured to contain the inner container containing the chemical indicator, and at least one hole arranged proximate the open end. The cap is configured to engage with the outer container to close the open end, and the at least one hole is configured to provide a flow path for the gaseous sterilant into the chamber.

A selectively scent infusible face masking assembly for filtering and scenting air includes a facemask, a pocket panel, and a plurality of pads. The facemask is selectively positionable over a nose and mouth of a user so that the facemask is removably engaged to a head of the user. The facemask filters particulates from air passing through the facemask. The pocket panel has opposing edges and a bottom edge that are engaged to the facemask to define a pouch. Each pad is infused with a respective aroma compound so that the plurality of pads comprises pads that are infused with a variety of aroma compounds. The pads are sized complementarily to the pouch. A respective pad is selectively insertable into the pouch so that the respective pad releases an associated aroma compound into the air passing through the facemask.

Embodiments of a controlled odor emission system and device include an odor presentation port tube and an odor tray securely retained against a platform, a valve housing securable to the platform adjacent the tray, a valve secured within the valve housing and an actuator for moving the valve. By controlling movement of the valve, precise amounts of an odor can be dispensed under programmatic control for training animals. Further, a system incorporating a central control unit and a reward dispenser in communication with an odor emission device to facilitate animal training.

A free-standing device for releasing fragrances includes a hollow external cylinder having an inner surface engaging the outer surface of an internal cylinder, the internal cylinder being closed. The inner surface of the external cylinder and the outer surface of the internal cylinder are fully at contact with each other. If open, the internal cylinder projects beneath the external cylinder, allowing the user to insert it into a support having a resting surface and an upper projection perforated centrally. The upper projection has aeration holes, sliding the internal cylinder with respect to the external cylinder exposing a portion of the inner surface of the external cylinder and the outer surface of the internal cylinder. A perfumed scent is applied on the inner surface of the external cylinder and/or on the outer surface of the internal cylinder; the internal cylinder having break-lines for removing portions of the internal cylinder.

This disclosure relates to a method for disinfecting a space. The method includes spraying a composition containing triethylene glycol into a space containing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in an amount effective to inactivate SARS-CoV-2.

The use of compositions including two or more cucurbiturils in counteracting malodour in a moist environment. The two or more cucurbiturils are selected from CB[5], CB [6], CB [7] and CB[8]. Also provided is a method for counteracting malodour in a moist environment, including application of a composition including a mixture of two or more cucurbiturils selected from CB[5], CB[6], CB[7] and CB[8].
