Is there a formaldehyde hazard associated with the use of sanitary napkins?

Formaldehyde is widely present in nature, and small amounts may be found in furniture, clothing, food, and automobiles. Moreover, national standards impose extremely stringent regulations on formaldehyde content in sanitary napkins. Therefore, sanitary napkin products that meet the relevant national testing requirements will not pose any harm to women's health.

Do sanitary napkins contain fluorescent whitening agents?

Some consumers have reported observing fluorescent phenomena when sanitary napkins are exposed to ultraviolet light, leading them to believe that these products contain fluorescent brightening agents harmful to human health. In fact, fluorescence is a normal physical phenomenon widely observed in nature. Many organisms—including fireflies, shrimp, crabs, jellyfish, and certain mushrooms—emit light due to the presence of fluorescent proteins within their bodies. Additionally, essential nutrients such as vitamin A, vitamin B2, tryptophan, and tyrosine in the human body also exhibit fluorescence under ultraviolet light exposure.

Due to variations in raw materials and manufacturing processes, sanitary napkins from different brands may contain fluorescent substances inherent in certain materials that emit light under ultraviolet lamp exposure. However, this does not equate to the addition of fluorescent brighteners, nor does it prove harmful to human health. Therefore, the presence of fluorescent emission shows no direct correlation with the use of fluorescent brighteners or potential health risks. The claim that fluorescent emission indicates the presence of brighteners is scientifically unfounded. In fact, national standards explicitly prohibit the use of migratable fluorescent substances in products to ensure consumer safety. By choosing certified products manufactured by reputable brands that meet national testing standards, consumers can rest assured their sanitary napkins will contain no fluorescent brighteners and can be used with confidence.
