Experts warn that melting fragrance flakes may produce toxic particles. According to Newsweek, flameless and smokeless fragrance scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scented scent
study points out that "although there is no flame and smoke, fragrance scents are easier to release large amounts of "volatile organic compounds" (VOC) than traditional fragrance scents, because fragrance scents have higher fragrance and direct melting of scents increases the surface area of melting the scents."
{99}This study analyzed 15 commercially available fragrance flasks, including those with no taste and fragrance. The melting time was set for two hours. During the melting period and after, the air samples were collected at several distances of the fragrance flasks. It was found that the sample air contained nanoparticles.
The American Chemical Society issued a statement saying that the detected substances “are comparable to the concentration of traditional burning pellets reported in the past”, warning that fragrance particles can cause risks because their molecules are small enough to enter blood vessels through the respiratory tract.
Research points out that the compounds released by the fragrance syringe "react with indoor ozone, producing new particles, thereby significantly increasing the concentration of nanoparticles in the indoor air." In addition, the chemical substances produced by the fragrance syringe "have similar composition to emissions from gas stoves, diesel engines and natural gas engines."
The study found that "New Particle Formation (NPF) events developed by melting and touching fragrance can cause human respiratory tract to be exposed to harmful environments for a long time."
The American Chemical Society pointed out that past studies have shown that exposure to high concentrations of nanoparticles in indoor environments may be closely related to health risks, such as decreased cognitive function and increased childhood asthma.
Newly discovered the challengers' views on fragrance flasks, and researchers pointed out that it is necessary to further study "the toxicity of newly formed nanoparticles and gain an in-depth understanding of the impact of these nanoparticles on the environment and human health." A report by Grandview Research, a market research firm, pointed out that the global home fragrance market size is valued at 11.12 billion yuan in 2023 and will grow at a 9% compound annual growth rate from 2024 to 2030.
