The GB/T 34448-2017 standard specifies a method for the determination of free formaldehyde content in tissue paper and paper products by water extraction and partial hydrolysis, which is suitable for tissue paper, toilet paper, wet wipes, diapers, sanitary napkins and other products. The standard provides two detection methods: Acetylacetone-Spectrophotometric method, spec-trophotometry and High performance liquid chroma-tography, HPLC, with detection limits of 10 mg/kg and 6.0 mg/kg respectively. Through the implementation of this standard, the formaldehyde content in tissue paper products can be effectively evaluated to ensure product safety and protect consumer health.
