Can the acidity or alkalinity of sanitary napkin products themselves affect the vaginal microenvironment?

Medical experts explain that menstrual blood flows outward through the vagina during menstruation, and the vaginal environment typically maintains a slightly acidic pH level. As external products, sanitary pads' pH values during normal use are primarily influenced by menstrual blood or other secretions, making it difficult to reverse the vaginal pH balance. Moreover, most women possess a robust self-regulating acid-base system in the vagina. Through lactobacilli bacteria, glycogen is continuously converted into lactic acid, which helps maintain the vaginal acidity and inhibit pathogen growth. In summary, vaginal pH levels are not affected by the pH values of sanitary pad products themselves.

What is the villus pulp in sanitary napkins? Does it affect women's health?

The primary raw material for pulp pulp is coniferous wood, such as pine, spruce, and fir, which serves as a natural source. Pulp pulp inherently possesses hydrophilicity, enabling rapid liquid absorption, and has been widely used in absorbent hygiene products like sanitary napkins for decades. Given that sanitary napkins come into direct contact with human skin, pulp pulp must meet stringent hygiene standards and cleanliness requirements. During production, it is essential to control microbial growth while preventing contamination from insects and foreign particles. Packaging requirements for pulp pulp rolls are also highly demanding. Additionally, during transportation, packaging materials must remain clean and intact to avoid contamination from damaged materials. Therefore, pulp pulp is a natural raw material that does not pose any risks to women's health.
