General Knowledge
Ma Xin, an expert at the Quality Inspection Center of the China National Pulp and Paper Research Institute, states: "High-quality facial tissues should not shed lint, dust, or dye, and should retain a certain level of strength when wet. Their surface should be clean, and the texture-characterized by fine, uniform creping-should feel soft. Boxed tissues should allow the next sheet to be pulled up automatically when one is removed; pocket-sized tissues should be neatly packaged with a resealable opening, ensuring the pack can be closed again after a tissue is withdrawn to maintain cleanliness and prevent contamination."
Facial tissues and toilet paper are subject to different standards, production environments, and hygiene requirements. Simply put, facial tissues are held to higher hygiene standards than toilet paper; therefore, it is best not to use them interchangeably-and one should certainly not use toilet paper to wipe one's mouth.
Health Considerations
Whiter is not necessarily better when it comes to facial tissues. Product standards specify a whiteness range of 85%–90% for Grade A tissues. Some manufacturers add excessive fluorescent whitening agents to boost whiteness beyond 90%, causing the product to fail standard requirements. Such tissues often appear unnaturally white with a harsh tone, and consumers are advised to avoid purchasing them. A banknote detector can be used to make a preliminary check for the presence of fluorescent whitening agents in facial tissues.
