China: Shanghai tests 28 brands of eyelash glue, finds most contain carcinogens
Key facts
- Shanghai authorities tested 28 brands of false eyelash adhesive and found that the majority contained carcinogenic substances
- A technician in Jing’an District stated that odorless adhesives have low bonding strength, implying a trade-off between safety and performance
- Consumers reported immediate eye irritation, itching, and burning sensations after using the tested false eyelash adhesives
- Experts warned that prolonged use of these specific adhesives can lead to severe conditions like corneal ulcers and perforation
- A staff member at Pingdu Jienai False Eyelash Co. Ltd. claimed that all glues contain formaldehyde, dismissing specific chemical concerns
The trend of applying false eyelashes has gained significant popularity among beauty enthusiasts, yet it carries hidden health risks. Recent testing of adhesives used for false eyelash application in Shanghai revealed that the majority of the products contain carcinogenic substances.
Inside a lash salon in Jing’an District, the air is thick with the pungent odor of glue. Staff members at the shop claim that a stronger chemical smell correlates with a better application result.
A technician at the salon stated, “In any nail or lash studio, the adhesives used for eyelash extensions all have a distinct odor. If a product is completely odorless, I can tell you with absolute certainty that its bonding strength is low.”
Ms. Xu reported that immediately after the procedure, her eyes felt intensely irritated. She noted that she had to use a fan to continuously blow-dry the adhesive, and only then did the discomfort subside.
Ms. Wang described her experience, noting that her eyes initially became itchy, followed by a burning sensation around the eyelids, which eventually led to excessive tearing.
In response to these concerns, the Shanghai Consumer Rights Protection Committee recently tested 28 popular lash adhesives available in the market. The results revealed that 20 products contained formaldehyde, a Group 1 carcinogen, while 9 samples tested positive for toluene, a Group 3 carcinogen. Additionally, 24 of the products were found to contain hydroquinone, a skin-lightening agent prohibited in cosmetics. Some of the adhesives even contained components typically found in industrial-grade 502 glue.
The brands involved include Meiliran, Tang Xianzi, Jienai'er, Jieya Yiduo, and Qiao Xiang Da He Jiao. Most of these products are manufactured in Pingdu and Qingdao in Shandong Province, as well as in Guangzhou, Guangdong. Manufacturers stated that lash adhesives are not classified as cosmetics and therefore lack specific regulatory standards. They noted that it is an industry norm for such glues to contain formaldehyde.
A staff member at Pingdu Jienai False Eyelash Co. Ltd. dismissed concerns about the chemical, stating, “Don’t bring up formaldehyde or not; this stuff, all glues contain formaldehyde, right?”
Experts warned that prolonged use of such adhesives can lead to corneal ulcers and corneal perforation. Industry insiders urged the prompt introduction of regulatory standards to bring eyelash glue under the supervision framework for cosmetics.
