Problems solved by technology

[0002] The fragrance retention time of perfume is an important index to measure the quality of perfume. It is related to many factors, such as the concentration of essence, the volatility of essence, the adhesion of fragrance components in perfume, temperature, humidity, and wind speed. Differences in people's physique, body temperature and skin quality will lead to different fragrance retention time when using the same perfume. At present, there is no unified test method and standard for the test of fragrance retention time of perfume.

Embodiment 1

[0030] A kind of perfume lasting time tester, instrument structural parts such as figure 1 As shown, the instrument profile is as figure 2 As shown, it includes: a constant temperature and humidity device (1), which has the function of adjusting humidity and temperature, and is composed of a constant temperature and humidity unit, a temperature and humidity sensing probe (9), a signal feedback unit, and an adjustment unit. The constant temperature and humidity unit It is mainly composed of a humidifying device, a dehumidifying device, and a semiconductor thermoelectric cooling / heating device; the exhaust fan (2) is used to generate wind energy; the wind speed controller (3) connected to the exhaust fan (2) is used to adjust the wind speed by a frequency converter to realize The stepless speed regulation can accurately adjust and control the wind speed of the exhaust fan (2); the stainless steel hollow cylinder (4) has an inner diameter of 15.0 cm and a length of 30.0 cm, and ...

Embodiment 2

[0032] An operation method of an accelerated tester for fragrance retention time of perfume. Considering the influence of wind speed on the fragrance retention time of perfume, the frequency converter adjusts the wind speed of the exhaust fan to 5.53m / s.

[0033] Considering the influence of temperature and humidity on the fragrance retention time of perfume, use a constant temperature and humidity device to adjust to a constant temperature and humidity, and carry out real-time monitoring through a digital display device to keep the temperature and humidity constant within a certain range (temperature: 20-32°C, Humidity: 45-75%RH). Such as image 3 As shown, after the tester is turned on, the data measured by the temperature and humidity sensor probe (9) at the air outlet first passes through the signal feedback unit, then through the adjustment unit, to the constant temperature and humidity unit, and the constant temperature and humidity unit further adjusts the temperature a...

Embodiment 3

[0042] An operation method of an accelerated tester for fragrance retention time of perfume. Considering the influence of wind speed on the fragrance retention time of perfume, the frequency converter adjusts the wind speed of the exhaust fan to 5.37m / s.

[0043] Considering the influence of the smelling distance (the positive distance from the tip of the nose to the sample sponge ball) on the fragrance retention time test, the sniffing distance is specified as 5cm.

[0044] Perfume sample: Commercially available BVLGARI Crystal Pure Fragrance Perfume for Women

[0045] Evaluation method of fragrance retention time: the record of strong fragrance is "+++", the record of fragrance that can be smelled clearly is "++", the record of fragrance that can be smelled just now is "+", and it can be smelled only after hard smell or not at all The record of "-" is "-", and then after a comprehensive analysis, evaluate the degree of fragrance retention.

[0046] Considering the differenc...

Abstract

The invention discloses a perfume fragrance holding time accelerating tester. The tester comprises a constant temperature and humidity device, an exhaust fan, a wind speed controller connected to theexhaust fan, a hollow cylinder having one end connected to the housing of the exhaust fan, a sponge ball and a clip for fixing the sponge ball. The invention also discloses a method for operating theperfume fragrance holding time accelerating tester. The operation method of the invention is used to test the perfume fragrance holding time to avoid the difference between the body temperature and the sensory sense of the human body and establish a uniform detection method for the fragrance holding time of various perfumes so as to facilitate more accurately and objectively estimate the perfume quality for production guide and formula design. The perfume fragrance holding time accelerating tester is convenient to use, rapid, efficient, small and easy for industrial production.

Description

technical field [0001] The invention relates to an accelerated tester for fragrance retention time of perfume and an operation method suitable for the accelerated tester for fragrance retention time of perfume. Background technique [0002] The fragrance retention time of perfume is an important index to measure the quality of perfume. It is related to many factors, such as the concentration of essence, the volatility of essence, the adhesion of fragrance components in perfume, temperature, humidity, and wind speed. People's physique, body temperature and skin quality are different, and the fragrance retention time of the same perfume will also be different. At present, there is no unified test method and standard for the test of the fragrance retention time of perfume. [0003] The present invention designs an accelerated tester for the fragrance retention time of perfumes, and uses this instrument to test the fragrance retention time of perfumes, avoiding the differences i...
