Same with paper towels "Toilet paper" and "tissue paper" The difference is really big Tissue paper is used to wipe hands, mouth and face The implementation standard is GB/T 20808 Toilet paper is toilet paper Such as various types of paper rolls Its implementation standard is GB/T 20810 By comparing the standards, we can find Hygiene standards for both It can be said that they are far apart According to national standards, tissue paper can only be made from virgin pulp, and recycled fiber materials such as waste paper are not allowed, while toilet paper is allowed to be made from recycled pulp (fiber) materials. So, from a clean and hygienic perspective, don't use toilet paper to wipe your mouth! What is tissue paper? The implementation standard for tissue paper is GB/T 20808-2011 "Tissue Paper", which defines tissue paper as paper facial tissues, paper napkins, paper handkerchiefs, etc. Tissue paper can be divided into two grades according to quality: superior product and qualified product; according to product performance, it can be divided into super soft type and ordinary type; according to the number of layers, it can be divided into single layer, double layer or multi-layer. Superior products vs qualified products The standard divides paper towels into two grades according to their quality: superior products and qualified products. Many quality requirements of superior products are better than those of qualified products. Safety indicators 01 Fluorescent agent You must have heard that too white paper towels are because of the addition of fluorescent agents. However, GB/T 20808 strictly stipulates that fluorescent brighteners must not be detected in paper towels, and the brightness (whiteness) of paper towels must be less than 90%. 02 Residual acrylamide monomer The residual acrylamide monomer is irritating to the skin and eyes and may cause allergic reactions. This substance may be produced during the production process of paper towels. GB/T 36420-2018 "Safety Assessment Management System for Chemicals and Raw Materials for Household Paper and Paper Products" stipulates that acrylamide in tissue paper should be ≤0.5mg/kg. 03 Microorganisms GB 15979-2002 "Hygiene Standard for Disposable Hygiene Products" is the hygiene standard for paper towels, which sets strict requirements for the total bacterial colony count, coliform group and other microbial indicators of paper towels: Buy "Paper" First, choose: choose the right one, not the cheap one. Paper towels are one of the most commonly used daily necessities. When purchasing, you should choose the type that meets your needs and try to choose a trustworthy big brand. Second look: look at the product details at the bottom of the package. There are usually product details at the bottom of the paper towel package. Pay attention to the implementation standards and product raw materials, and try to choose high-quality products. Third touch: A good tissue feels soft and delicate, and will not shed hair or powder if you rub it gently. At the same time, you should also compare its toughness. If you pull a tissue with a little force, wrinkles will appear on the tissue, but it will not break. That is a good tissue! Fourth, smell: smell the smell. When buying paper towels, you should smell it. If there is a smell of chemical agents, do not buy it. When buying, try not to buy scented ones, so as not to ingest the fragrance when wiping your mouth, which will affect your health.
