Hygiene Risks from Prolonged Use & Improper Change Frequency

2026-03-04

The core risk is bacterial proliferation and disruption of the local microflora from use beyond the product's designed operating conditions, regardless of absorption capacity.

Parameterized Evidence:
Defined Operating Conditions: For an "ultra-thin" pad (thickness ≤1.5mm) with a nominal absorption ≥10mL, the recommended safe usage duration​ typically does not exceed 4 hours. This is a hygiene guideline based on bacterial growth curves, not product failure time. In a damp 35-37°C environment, bacteria like S. aureuscan reach the logarithmic growth phase within hours.
Absorption Performance Parameter: Rewet is critical. Per Chinese standard GB/T 30133, premium products should have a rewet value ≤1.0g. High rewet indicates a damp surface conducive to bacterial growth.
User Guidance: Clearly distinguish between "absorption saturation" and "hygiene safety" thresholds. Saturation may manifest as leakage, but hygiene risk exists before leakage occurs.
