Answers
Answer:
Packaging toothpaste in pumps and stand-up tubes was introduced during the 1980s and marketed as a neater alternative to the collapsible tube. In 1984, the Colgate pump was introduced nationally, and in the 1990s, stand-up tubes spread throughout the industry, though the collapsible tubes are still available.
Explanation:
Most of today's toothpaste tubes are made from sheets of plastic laminate—usually a combination of different plastics—often sandwiched around a thin layer of aluminum. The mix of materials makes the tubes impossible to recycle through conventional methods, explained Colgate.
Besides aiding in the removal of plaque and food particles, abrasives like hydrated silica can also help to remove stains, which makes them useful as whitening agents in toothpastes as well. Abrasives used in toothpaste date back over 2000 years, where paste mixtures were once made with bones and ground shells.
Toothpastes are pastes, powders, liquids, or other preparations intended for cleaning the teeth. If the product is also intended to prevent the formation of cavities (carries), then it is regulated by the Food and Drug Administration as an Over-The-Counter (OTC) drug.
Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivitis).
A big container filled with toothpaste is fixed above the conveyor belt. From a nozzle at the bottom of the container, the toothpaste is let into each of these tubes as they move along the conveyor belt. But the paste is not filled all the way to the brim. About half an inch is left so that it can be sealed.
