What's The Cotton Buds
Cotton swabs (American English) or cotton buds (British English) are handheld items that consist of one or two small wads of cotton wrapped around one or both ends of a short rod made of wood, rolled paper or plastic.
The first mass-produced cotton swab was developed in 1923 by Polish-American Leo Gerstenzang after he watched his wife attach wads of cotton to toothpicks.His product, originally named "Baby Gays", "Q-tips Baby Gays", and finally just "Q-tips" (meaning quality tips) went on to become the most widely sold brand name of cotton swabs/buds. The term “Q-tips” is often used as a genericized trademark for cotton swabs in the United States and Canada.The Q-tips brand is owned by Unilever and had over $200 million in US sales in 2014. Johnson's buds are made by Johnson & Johnson.
The traditional cotton swab has a single tip on a wooden handle, and these are still often used, especially in medical settings. They are usually relatively long, about 6 inches (15 cm). These often are packaged sterile, one or two to a paper or plastic sleeve. The advantage of the paper sleeve and the wooden handle is that the package can be autoclaved to be sterilized (plastic sleeves or handles would melt in the autoclave).
Cotton swabs manufactured for home use are usually shorter, about 3 inches (7.6 cm) long, and usually double-tipped. The handles were first made of wood, then made of rolled paper, which is still most common (although tubular plastic is also used). They are often sold in large quantities, 100 or more to a container.
Plastic swab stems exist in a wide variety of colors, such as blue, pink or green. However, the cotton itself is traditionally white.
How to use
The most common use for cotton swabs is to clean or caress the ear canal and/or to remove earwax, despite this not being a medically recommended method for removing earwax. Cotton swabs are also commonly used for applying and removing makeup, as well as for household uses such as cleaning and arts and crafts. They are also handy for touching up nail polish that gets on the surrounding skin.
Medical-type swabs are often used to take microbiological cultures. They are rubbed onto or into the infected area, then wiped across the culture medium, such as an agar plate, where bacteria from the swab may grow. They are also used to take DNA samples, most commonly by scraping cells from the inner cheek in the case of humans. They can be used to apply medicines to a targeted area, to selectively remove substances from a targeted area, or to apply cleaning substances like Betadine. They are also used as an applicator for various cosmetics, ointments, and other substances.
A related area is the use of swabs for microbiological environmental monitoring. Once taken, the swab can be streaked onto an agar plate, or the contents of the tip removed by agitation or dilution into the broth. The broth can either then be filtered or incubated and examined for microbial growth.
Cotton swabs are also often used outside of the field of personal hygiene:
- Often used in plastic model kits construction, for various applications during the application of decals or painting. Special brands of cotton swabs exist for this purpose, characterised by sturdier cotton heads and varied shapes of those heads.
- Can be used in the dyne test for measuring surface energy. This use is problematic, as manufacturers differ in the binders they use to fix the cotton to the stem, affecting the outcome of the test.
- They are frequently used for cleaning the laser diode lens of an optical drive in conjunction with rubbing alcohol. Similarly, they're used for cleaning larger computer parts such as video cards, and fans. They were also used widely in the past to clean video game cartridges.
