Overview - ISO 24669:2021 and water-absorbent polyacrylate
ISO 24669:2021 specifies requirements for water-absorbent crosslinked polyacrylate used in urine absorbing products (superabsorbent polymers for incontinence aids). The standard sets safety and performance pass criteria, storage and labeling expectations, and prohibits certain constituents to ensure consistent product quality and consumer safety in urine-absorbing applications.
Key topics and technical requirements
ISO 24669:2021 focuses on measurable properties and references established test methods (mainly ISO 17190 series). Key technical requirements include:
- Absorbing capacity: ≥ 10.0 g/g (tested by ISO 17190-6)
- Residual acrylate monomer content: ≤ 1 000 mg/kg (ISO 17190-2)
- pH range: 4.5 to 8.0 (ISO 17190-1)
- Moisture content: ≤ 20.0 % (ISO 17190-4)
- Particle size distribution: ≤ 1.0 % particles > 850 µm and ≤ 1.0 % particles < 45 µm (ISO 17190-3)
- Bulk density: 0.30 to 1.00 g/ml (ISO 17190-9)
- Quantity of heavy metals (expressed as Pb): ≤ 20 mg/kg (Japanese Pharmacopoeia 1.07 Heavy Metals Limit Test, Method 2). Note: ISO/TR 17276 gives alternative approaches for heavy metal testing.
- Constituent restriction: Acrylamide shall not be used or added in manufacturing.
Additional requirements cover product storage (sealed bags, indoors, out of direct sunlight) and supplier information (product name, ISO 24669 conformity claim, manufacturer ID, and batch identification included on labels, certificates, invoices).
Practical applications and who uses this standard
ISO 24669 is used to ensure the safety, consistency, and performance of superabsorbent polymers in urine absorbing products. Typical users include:
- Manufacturers of superabsorbent polymers and absorbent hygiene products (diapers, adult incontinence pads, medical incontinence aids)
- Quality control and testing laboratories validating raw materials and finished products
- Procurement and supply chain teams verifying supplier declarations and batch traceability
- Regulatory and compliance teams assessing product safety and material conformity
- Product developers and R&D teams specifying polymer performance and material selection
Using ISO 24669 helps reduce product failures, ensures consumer safety, and supports market access by aligning with internationally recognized requirements for water-absorbent polyacrylate in urine absorbing products.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
