Most of us can't imagine living without toilet paper. The average American uses over 100 single rolls—about 21,000 sheets—each year. It's used not only for bathroom hygiene, but for nose care, wiping up spills, removing makeup, and small bathroom cleaning chores. Manufacturers estimate that an average single roll lasts five days.
Toilet paper, paper towels, napkins, and facial tissues are sanitary papers, personal products that need to be clean and hygenic. They're made from various proportions of bleached kraft pulps with relatively little refining of the stock, rendering them soft, bulky, and absorbent. Sanitary papers are further distinguished from other papers in that they are creped, a process in which the paper is dried on a cylinder then scraped off with a metal blade, slightly crimping it. This softens the paper but makes it fairly weak, allowing it to disintegrate in water.
Toilet paper can be one-or two-ply, meaning that it's either a single sheet or two sheets placed back-to-back to make it builder and more absorbent. Color, scents, and embossing may also be added, but fragrances sometimes cause problems for consumers who are allergic to perfumes. The biggest difference between toilet papers is the distinction between virgin paper products, which are formed directly from chipped wood, and those made from recycled paper. Most toilet paper, however, whether virgin or recycled, is wrapped around recycled cardboard cylinders.
