ISO 24669 addresses water-absorbent polyacrylate in urine absorbing products. ISO 24669 focuses on requirements for water-absorbent crosslinked polyacrylate in urine-absorbing products.
Acrylamide shall not be used or added in the manufacturing of water-absorbent polyacrylate.
Product type names of absorbent incontinence products for urine and/or feces are found in ISO 22748.
Water-absorbent polyacrylate is used in many industries, especially polyacrylates. Some applications include thickeners, flocculants, dispersants, and drag-reducing agents. Polyacrylates are also used as environmentally friendly adhesives or coating.
ISO 24669 on water-absorbent polyacrylate in urine absorbing products is useful for-
Water-absorbent polyacrylate is powdered or fibrous resin comprising of polyacrylate that can absorb and retain water and/or aqueous solutions 10 times to 1 000 times its own weight.
ISO 24669 lays out methods that have been in use for several years to characterize the safety and performance of water-absorbent polyacrylate in urine absorbing products.
Water-absorbent polyacrylate is non-toxic and safe from major risks. Its also considered non-biodegradable and may cause salinization of soil when added in large quantities.
