Introduction of GB/T 45369-2025

GB/T 45369-2025 Absorbent sanitary paper products and raw materials - Evaluation method of deodorant performance 1 Scope This document describes four methods for evaluation of the deodorant performance of absorbent sanitary paper products and raw materials: detector tube method, gas detector method, LC-MS/MS method and GC-MC method. This document is applicable to the evaluation of deodorant performance for absorbent sanitary paper products, including but not limited to baby diapers (pads, liners), adult diapers (pads, liners), sanitary napkins (pantiliners), women's sanitary pants, pet pads (pants), and paper cat litter. It is also applicable to the evaluation of deodorant performance for raw materials such as superabsorbent polymers, fluff pulp, top sheets, composite absorbent cores, distribution layers, absorbent paper, and airlaid paper. It may also serve as a reference for other cat litters. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 6682 Water for analytical laboratory use - Specification and test methods GB/T 21331-2021 Fluff pulp GB/T 27417 Confirmation assessment - Guidance on validation and verification of chemical analytical methods 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 unpleasant odor unpleasant odor associated with the environment in which people live Note: For example, excrement odor, body odor, etc. 3.2 chemical components of unpleasant odor main chemical components of unpleasant odor in people's living environment 3.3 deodorant performance desired purpose of reducing odor in the surrounding air Note: The expression of deodorant performance includes but is not limited to odor purification, odor removal, etc. 3.4 evaluation of deodorant performance measured reduction rate of the chemical components of unpleasant odor in the specimen-containing container compared with the blank test without specimen 4 Principle Place the test specimen and a specified initial concentration of chemical components of unpleasant odor into a sampling bag or conical flask. After allowing the specimen to interact with the chemical components of unpleasant odor for a predetermined duration, measure the concentration of these components in both the specimen-containing and specimen-free sampling bags or conical flasks using detector tube method, gas detector method, LC-MS/MS method and GC-MC method. Calculate the reduction rate of each chemical component of unpleasant odor to evaluate the deodorant performance.
