An olfactory environment management system includes a plurality of odor sensors, an aroma diffusing device, and a control server. Each of the plurality of odor sensors detects a chemical substance and determines a detected concentration of the chemical substance. The aroma diffusing device is equipped with first to n-th aroma capsules selected among a plurality of aroma capsules. The control server controls a combination of scents diffused from the aroma diffusing device. The aroma diffusing device determines an epicenter concentration of the chemical substance based on the detected concentration received from each of the plurality of odor sensors and transmits an identity of the chemical substance and the epicenter concentration to the control server. The control server individually controls an intensity of the emission of the aromatic substance of each of the first to n-th aroma capsules based on the identity of the chemical substance and the epicenter concentration.

The present invention relates to a method of capturing and stabilising volatile thiol malodour generated on the human skin, comprising steps of: i) contacting the human skin with a substrate, ii) absorbing said thiol into the substrate, and iii) reacting said thiol with a thiol-capture agent. The invention also relates to a method of quantifying said thiol, a method of assessing the deodorizing performance of a cosmetic composition on the human skin.

An aroma diffuser, including: an oil supply structure, provided with an oil storage bottle for containing essential oil and an oil delivery pipe connected to the oil storage bottle, the oil delivery pipe includes a liquid outlet, and an end side of the oil delivery pipe is provided with an atomizing space; and an air delivery structure, provided with a working mode and a wall-breaking mode, in the working mode, an atomizing airflow is generated, and a negative pressure is formed to force the essential oil to enter the atomizing space, in the wall-breaking mode, an impinging airflow and a buffering airflow are alternately generated, or a buffering airflow and an impinging airflow are alternately generated, the impinging airflow flows through the atomizing space and breaks through a surface tension of the essential oil, the buffering airflow flows through the atomizing space and takes the essential oil away.

The present invention relates to a solid fragrance composition which can improve the load rate of a fragrant material, can selectively load a fragrance which can be acquired during the aging process of a mixed fragrant material, maintain the fragrance from the beginning of the loading, and improve the longevity of the fragrance at a uniform strength. In addition, the issue of being harmful to the human body can be resolved by reducing powder flying around, and stability at a high temperature can be improved so as to be applied in various environments.
