Description

Method and device for rapidly detecting tetrahydrocannabinol in cosmetics
Technical Field
The invention relates to the technical field of detection, in particular to a method and a device for quickly detecting tetrahydrocannabinol in cosmetics.
Background
The hemp cosmetics are generally cosmetics added with hemp extracts, and the most common components in hemp are Tetrahydrocannabinol (THC) and Cannabidiol (CBD), compared with Cannabidiol (CBD), the Cannabidiol (CBD) has higher medicinal value, and the Cannabidiol (CBD) is applied to treating acne, eczema, promoting wound healing and the like due to the alleged effects of anti-inflammation, pruritus inhibition and antibiosis. In the catalogue of names of used cosmetic raw materials (2015 edition) in China, cannabis kernel, cannabis seed oil and cannabis leaf extract are allowed to be used as cosmetic raw materials. With the intensive research on cannabis, Cannabidiol (CBD) is found to block the influence of Tetrahydrocannabinol (THC) on the nervous system of a human body, has pharmacological activities such as spasm resistance, rheumatoid arthritis resistance, anxiety resistance and the like, and can effectively improve sleep quality, relax nerves, relax mood, relieve pressure and prevent depression. Cannabidiol (CBD) is broadly effective and is not limited to a single disease species or organ health care. Under the premise of not causing obvious damage to any cognitive system, Cannabidiol (CBD) has the functions of relieving stress, resisting anxiety, resisting pressure and the like, and has obvious positive effects on preventing various diseases such as senile dementia, epilepsy, infantile autism, cancer, liver cirrhosis and the like. In addition to medicinal value, the Cannabidiol (CBD) product presents diversified development and perfectly adapts to the update and iteration rate of the health care product market, the cannabidiol oil health care product extracted from the Cannabidiol (CBD) comprises spray, capsules, concentrated solution, paste, drops and the like, and the cannabidiol oil health care product with various tastes or concentrations can also be prepared according to the requirements of consumers.
The Tetrahydrocannabinol (THC) is the most important psychoactive substance in the cannabis sativa, has a neurohallucinogenic effect and can generate hallucinations, the Tetrahydrocannabinol (THC) content of more than 0.5 percent is drug cannabis sativa, and the drug is listed as one of three drugs in parallel with heroin and cocaine by the drug banning convention of the United nations, which becomes the reason for banning cannabis in many countries, and the industrial planting variety of the cannabis sativa with the THC content of less than 0.3 percent is allowed to be planted in part of the provinces of China.
Before the cannabis extract is added into cosmetics, multiple purification is needed to remove Tetrahydrocannabinol (THC), but because Cannabidiol (CBD) and Tetrahydrocannabinol (THC) are isomers of each other, the Cannabidiol (CBD) and the Tetrahydrocannabinol (THC) are similar in properties, the THC purification difficulty is high, the cost is high, the purification process and the processing level of each enterprise are different, the THC purification is incomplete, and the cosmetics prepared from the THC can contain the THC. Tetrahydrocannabinol (including isomers and stereochemical variants thereof) and the like are recorded in the 'psychiatric drug administration catalog' of China and are banned.
For example, lip cosmetics are applied to lips, and are easily ingested with food by the human body along with eating; for example, essential oil products are equivalent to being sucked by human bodies in the process of lighting incense. These cosmetics contain higher concentrations of THC, equivalent to the intake of state regulated psychoactive substances. Therefore, it is very important to determine the THC content in the cosmetics. The existing detection methods for Tetrahydrocannabinol (THC) mainly comprise gas chromatography-tandem mass spectrometry and liquid chromatography-tandem mass spectrometry, but the existing detection methods all require complex sample pretreatment, so that not only is the detection operation process complex, but also the time required for sample analysis is long; and the requirements on manpower and instruments are high, and the mass spectrometer used in the mass spectrometer can work only under high vacuum, so that the detection process is usually finished in a laboratory due to the limitation of instruments, and the requirement of on-site rapid detection cannot be met.
