The safety of hot melt adhesives, a key bonding material used in sanitary napkins, is a major concern. Hot melt adhesives are composed of resins, plasticizers, adhesives, and stabilizers, possessing good adhesion and water resistance. Professional testing has verified that under normal use conditions, the hot melt adhesives in sanitary napkins do not pose a significant risk to human health. The polyolefin components may release harmful substances only at high temperatures, but the operating temperature of sanitary napkins is far below this. Furthermore, manufacturers adhere to strict quality control standards to ensure product safety. However, to avoid the potential release of harmful substances from hot melt adhesives in high-temperature and humid environments, it is recommended to store and use sanitary napkins in a dry and well-ventilated environment. In addition, proper use of sanitary napkins is crucial, including changing them as needed, maintaining hygiene, and avoiding products with excessive additives.
Currently, the hot melt adhesives used in sanitary napkins on the market all meet international standards and are materials that have undergone rigorous testing and inspection. Experimental data shows that using this type of hot melt adhesive does not cause adverse effects on the human body.
However, some untested sanitary napkins may use inferior hot melt adhesives, which may contain harmful substances. Long-term use may have adverse effects on health. Therefore, when purchasing sanitary napkins, you should choose products from reputable manufacturers and avoid buying cheap sanitary napkins without brand certification.
