摘要:
Provided herein are compositions containing a polymer substrate and a fragrance, methods for preparing such compositions, and methods for using such compositions for providing scents to an environment, such as a room or a vehicle. For example, the polymer substrate may comprise an alkyl acrylate, including but not limited to methyl acrylate. For example, the fragrance may comprise a polar or nonpolar molecule, or a collection of polar and/or nonpolar molecules. The resulting composition provides a temperature-stable fragrance composition that can be used within vehicles, has low to no residual odor, and can be loaded with at least 90% by weight of fragrance (relative to the weight of the polymer substrate).
摘要:
Disclosed is a fragrance adduct that is a reaction product between a polymeric amine and a reactive fragrance ingredient. The polymeric amine contains a backbone and at least one amino functional group, the reactive fragrance ingredient is an aldehyde, a ketone, an α,β-unsaturated electrophilic compound reactive towards the polymeric amine, or a combination thereof, and the reaction product is an imine compound or a Michael addition adduct. The fragrance adduct can be formulated into a fragrance composition, household product, personal care product, hair care product, or beauty care product. Also disclosed is a method for sequestering a fragrance using the fragrance adduct.
摘要:
Plastic component (1) for releasing fragrance, comprising at least a first wall (2) with a first side (4) and a second side (5) characterized in that, a second wall (3) is formed at least partially in parallel with the first wall (2) wherein the first wall (2) is spaced apart from the second wall (3) by at least two partition walls.
摘要:
Methods, systems, and devices are disclosed for implementing switchable dispensing and/or delivery of scented substances. In one aspect, a device includes a cartridge structured to include one or more chambers containing one or more scented substances contained in a corresponding chamber, a housing structured to include a compartment to hold the cartridge, an opening to allow the scented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to accelerate a scented substance from the corresponding chamber to the opening, and an actuator switch arranged in a corresponding transporting channel and operable to move between an open position and a closed position based on an applied signal to selectively allow passage of the scented substance from the corresponding transporting path.

The disclosure provides a fragrance distribution device including a housing. The housing has an aperture into which a hook, clip, adhesive peg, or other attaching device may be secured. This allows the housing to be placed into a vent or clipped to a surface at the convenience of a user. Typically the housing encloses a thermoplastic fragrance carrier.
摘要:
A fan type debugging apparatus is also disclosed in which the active ingredient impregnated body or mass is disposed in a wind inlet side of the fan type blower and is designed to provide a wind force resistance which in terms of the proportion of current consumption by the motor in the presence of the active ingredient impregnated body or mass to current consumption by the motor in the absence of the active ingredient impregnated body or mass, ranges from 5 to 25 %.
摘要:
The invention relates to the field of fragrance diffusion and to holders for fragrant substances. More specifically, the invention relates to a fragrance capsule (0) including: substrate elements (1) in which a fragrance is absorbed; a frame (2); and a first grille (3) and a second grille secured in the frame such as to face one another, each of the grilles including a plurality of bars (31, 32, 33, etc.), wherein the bars from one grille are spaced apart from one another and the grilles are spaced apart from one another such that a single layer of substrate elements can be held in the frame and between the grilles and air can flow through the frame around the substrate elements and the bars. The invention also relates to a fragrance-diffusing device including a capsule (0) according to the invention.
