Provided is a lighting device with an inactivation function, the lighting device allowing the addition of an inactivation function while being equal to conventional lighting devices in device size. The lighting device with the inactivation function includes: a UVC light source to emit ultraviolet light having a peak wavelength in a wavelength range from 200 nm to 230 nm; an LED light source to emit visible light; a single unit of an AC/DC converter to convert an AC voltage derived from an external power source into a DC voltage and output the DC voltage; a UVC light source-specific circuit part to convert the DC voltage output from the AC/DC converter into a voltage for lighting the UVC light source; and an LED light source-specific circuit part to convert the DC voltage output from the AC/DC converter into a current for lighting the LED light source.

A system for detecting and cleaning indoor air pollution adapted to be utilized in an indoor space with an HVAC system includes one or more outdoor gas detection devices, a plurality of channels, a plurality of indoor gas detection devices, a plurality of physical-typed or chemical-typed filtering devices, and a control central processor. The blower of the filtering device receives a control command so as to be driven and to generate an air convection which is directed. Therefore, the air pollution is filtered by the filtering component to allow the indoor air pollution data to approach to almost zero, so that a gas in the indoor space is cleaned to a safe and breathable state.

A fragrance delivery composition suitable for use in personal care and home care formulations, said composition comprising at least one fragrance fixative according to general Formula (I_F), at least one fragrance co-fixative chosen among those of Formulae (II_A)-(II_H), and at at least one fragrance component, wherein said fragrance component is different to the co-fixative. In general Formula (Ip), each of R₃-R₁₀ are COR₁ wherein each R₁ is independently methyl or isopropyl with the proviso that at least one R₁ is isopropyl. In particular, the fixative is sucrose acetate isobutyrate and the co-fixative is y-deltalactone and coumarin. The composition possesses an enhanced fragrance longevity and thereby provides a prolonged fragrance release over an extended period of time. The invention further relates to a method for the manufacture of the composition, a diluted composition comprising the composition and a diluent, personal and home care formulations comprising the composition or diluted composition and use of the composition or the diluted composition for the manufacture of personal and home care formulations.

An aroma container for adding an aroma substance to an air flow flowing through the aroma container comprises an upper wall (12), a lower wall (14) as well as at least one side wall (16, 18), which surrounds the aroma chamber, at least one air inlet opening (48) into the aroma chamber as well as at least one air outlet opening (24) from the aroma chamber, wherein an aroma substance, preferably in the form of an aroma concentrate, is present in the aroma chamber, the aroma substance being preferably applied to a carrier substance (42), wherein the aroma container further comprises a means for improved release of the aroma substance to the air flow flowing through the aroma container.
