Modern toilet paper
Seth Wheeler of Albany, New York, obtained the earliest patents for toilet paper and dispensers, the types of which eventually were in common usage in the United States.[3]
The advantages of toilet paper are that it is easy and intuitive to use, fairly absorbent, and it can be flushed in most countries where toilet paper is common. Most modern sewage systems, including septic tanks, can accept toilet paper along with human excreta.
Toilet paper is available in several types of paper, a variety of colors, decorations, and textures, to appeal to individual preference. Toilet paper is sometimes made from recycled paper; however, large amounts of virgin tree pulp is still used.[4] Environmentally friendly toilet paper may also be unbleached. Toilet paper products vary immensely in the technical factors that distinguish them: sizes, weights, roughness, softness, chemical residues, "finger-breakthrough" resistance, water-absorption, etc. The larger companies have very detailed, scientific market surveys to determine which marketing sectors require/demand which of the many technical qualities. Modern toilet paper may have a light coating of aloe or lotion or wax worked into the paper to reduce roughness. Quality is usually determined by the number of plies (stacked sheets), coarseness, and durability. Low grade institutional toilet paper is typically of the lowest grade of paper, has only one or two plies, is very coarse and sometimes has small amounts of unbleached/unpulped paper embedded in it. Mid-grade two ply is somewhat textured to provide some softness, and is somewhat durable. Premium toilet paper may have lotion and wax, and has two to four plies made of very finely pulped paper.
Two-ply toilet paper is the standard in many countries, although one-ply is often available and marketed as a budget option, it may also be more appropriate for use in toilets on boats and in camper-vans. Toilet paper, especially if it is marketed as "luxury", may be quilted or rippled (embossed), perfumed, colored or patterned, medicated (with anti-bacterial chemicals), treated with aloe, etc. Many novelty designs are also available on toilet paper, from cute cartoon animals to pictures of disfavored political celebrities to pictures of dollar bills. Women who are prone to vaginal Candidiasis yeast infections are advised by some medical experts to use white, unperfumed toilet paper.
Moist toilet paper was first introduced by the Kimberly-Clark in the United Kingdom by Andrex in the 1990s, and in the United States in 2001, two countries in which bidets are rare. It is designed to clean better than dry toilet paper after defecation, and may be useful for women during menstruation.
The manufacture of toilet paper is a large industry. Twenty-six billion rolls of toilet paper, worth about US$2.4 billion, are sold yearly in America alone.
