When 'bacteriostatic' is no longer a selling point and 'long-lasting antimicrobial' becomes a hard requirement, the entire R&D logic of the sanitary product supply chain is rewritten. In August 2026, the group standard T/CIAA 008—2026 for antimicrobial sanitary pads, pantyliners and period pants was officially released, replacing the 2020 version, introducing the concept of 'long-lasting antimicrobial' for the first time and requiring efficacy verification under simulated use conditions. What does this change mean for upstream nonwovens, functional additives and testing labs? The answers lie in the details of the revised standard.
Standard Revision: From Inhibition to Durable Antimicrobial
The most core change is in definitions. The old version only defined 'bacteriostatic sanitary pads', while the new version extends the scope to 'antimicrobial sanitary pads, pantyliners and period pants', and clarifies the product structure including outer covering material, top sheet, absorbent core, and leak-proof back film. More importantly, a new definition of 'long-lasting antimicrobial' is added: it requires adding bovine serum albumin to the skin-contact layer and placing it at (36±1)°C for no less than 8 hours, simulating actual use, after which the product must still exhibit antimicrobial (bacteriostatic) effects. This means products must not only be effective initially but also after use, imposing higher requirements on material durability and stability.
At the same time, the new standard aligns with GB 15979-2024 'Hygienic requirements for disposable sanitary products', systematically adjusting requirements for antibacterial performance, bacteriostatic performance, stability and toxicology, and updating test methods accordingly. This marks a further convergence between group standards and current national standards, and implies that companies relying on old test reports will fail to meet new regulations. For purchasers, the revision is not just a document update but a re-certification of product compliance.
Industrial Impact: Opportunities and Challenges for Nonwovens and Additive Suppliers
From the supply chain perspective, the new standard directly impacts suppliers of top sheets and absorbent layers. Traditional antimicrobial sanitary pads often use silver ions, zinc ions or organic antibacterial agents, but the 'long-lasting' simulation test mimics complex environments such as sweat and sebum, requiring antibacterial agents to remain effective after 8 hours of continuous contact. This imposes higher demands on the migration resistance, slow-release properties, and bonding strength with nonwoven substrates. Some low-end antibacterial finishing processes may be phased out, while companies with technologies such as microencapsulated slow release or melt-blown spinning will gain premium space.
For sanitary pad manufacturers, the revision means re-evaluating suppliers, adjusting formulations, and bearing additional testing costs. In particular, period pants have a more complex structure, making antibacterial treatment of the absorbent and skin-contact layers more challenging. Including period pants in the standard may drive companies to develop dedicated antibacterial fabrics rather than simply transplanting pad processes. Additionally, testing labs will face business expansion—the long-lasting test requires a new bovine serum albumin simulation step, needing temperature-controlled equipment and trained personnel, potentially extending testing cycles and raising costs.
From the market perspective, the new standard provides a basis for product differentiation. In the past, the 'antibacterial' label was often confusing and hard for consumers to verify. The new standard moves efficacy verification from static to dynamic through the 'long-lasting' indicator, helping build trust. For exporters, if target markets (e.g., Southeast Asia, Middle East) have similar requirements for antimicrobial performance of sanitary products, the new standard can serve as a technical reference or even a quality endorsement in trade negotiations.
