What is ISO 17190-10 about?
ISO 17190 discusses polyacrylate superabsorbent powders for urine-absorbing aids for incontinence. ISO 17190-10 outlines a test method to determine the mass fraction of soluble polymers present in crosslinked polyacrylate superabsorbent powders that can be extracted into the saline solution.
Note: ISO 17190-10 does not claim to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. It is expected that the person performing this test has been fully trained in all aspects of this procedure.
Who is ISO 17190-10 for?
ISO 17190-10 on polyacrylate superabsorbent powders for urine-absorbing aids is useful for:
- Manufacturers of polyacrylate superabsorbent powders
- Test centers for polyacrylate superabsorbent powders
- Regulatory authorities
- Manufacturers of products that use polyacrylate superabsorbent powders
Why should you use ISO 17190-10?
Polyacrylate superabsorbent powders absorb water or urine by a process called osmosis. When the polymer is placed in urine, there is a tendency for the atoms contained in the powder to distribute equally between the network and water. Extractables is the sum of the soluble acid and salt groups of monomeric, oligomeric, and polymeric carboxylates extracted from the superabsorbent polymer.
ISO 17190-10 guidelines provides requirements for Water, Sodium hydroxide solution, Hydrochloric acid solution, Sodium chloride solution, Standard buffer solutions, sampling, procedure, calculations, reports, precision for the determination of extractable polymer content by potentiometric titration. This helps in conducting proper assessment and provides reliable results for the determination of extractable polymer content that can be reproduced in any laboratory.
