With the arrival of summer, mosquitoes become active again. In order to effectively avoid mosquito bites, many people choose to use mosquito repellent patches. However, in recent years, many inferior mosquito patch products have appeared on the market, which are not only ineffective but may also pose potential threats to health. Therefore, it is important for consumers to understand the safety testing standards and methods of mosquito repellent patches.
1. Main ingredients of mosquito repellent patches
The main ingredients of mosquito repellent patches usually include natural or synthetic mosquito repellent substances, adhesives, paper, etc. Among them, mosquito repellent substances are the core ingredients of mosquito repellent patches, including natural or synthetic compounds, such as citronella, lemongrass, mosquito repellent, etc. These mosquito repellent substances evaporate into the air to form odors that interfere with the mosquitoes' sense of smell, thereby achieving the effect of repelling mosquitoes.
2. Safety testing standards
Ingredient safety
The safety of the ingredients of mosquito repellent patches is the primary consideration. Regularly produced mosquito patch products should strictly comply with relevant national regulations and use safe and non-toxic ingredients. For consumers, it is more reliable to choose mosquito patch products from regular brands and with relevant certifications.
Volatile gas concentration
mosquito repellent patches will release the smell of mosquito repellent substances during use to interfere with the mosquitoes' sense of smell. However, if the concentration of volatile gases is too high, it may cause discomfort to the human body and even cause adverse reactions such as dizziness and nausea. Therefore, it is necessary to detect the volatile gas concentration of mosquito repellent patches.
Adhesion
mosquito repellent patches need to have a certain amount of adhesion to ensure they stick firmly to skin or clothing when needed. If the adhesion is insufficient, the mosquito patch may fall off during use, affecting the mosquito repellent effect. Therefore, it is also necessary to test the adhesion of mosquito repellent patches.
3. Safety testing methods
Ingredient analysis
Analyze the ingredients of mosquito repellent patches to detect whether they contain toxic or harmful substances. Qualitative and quantitative analysis of ingredients can be carried out through spectroscopy, chromatography and other technical means.
Volatile gas detection
Use gas analysis instruments to detect the volatile gases released during use of mosquito repellent patches to assess whether their concentration is within a safe range.
Adhesion test
By simulating actual usage scenarios, the adhesion of mosquitoes to skin or clothing is tested. For example, you can put a mosquito patch on the surface of your skin or clothing for a period of time and observe whether it can adhere firmly.
In short, when choosing mosquito patch products, consumers should pay attention to the safety testing standards and methods of the products to ensure that the selected products comply with relevant regulatory requirements and have high safety and effectiveness. At the same time, you should also pay attention to the correct usage methods and precautions during use to ensure your own health and safety.
