Revision as of 16:14, 16 April 2007
Cotton swabs (British English: cotton buds) are used in first aid, other medical uses, cosmetics application, and a variety of other uses. They consist of a small wad of cotton wrapped around the end of a small rod, made of wood, rolled paper, or plastic. The most common type of usage is to dip the cotton end in a substance, then use the swab as an applicator for the substance. Sometimes swabs are also used for removal of substances.
The inventor of the cotton swab is supposed to have been one Leo Gerstenzang, in 1923 [1]. His product, which he named "Baby Gays," went on to become the most widely-sold brand name, "Q-tip".
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 six inches (15 cm or so). 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).
These medical-type swabs are often used to take microbiological cultures. They are swabbed onto or into the infected area, then wiped across the culture medium, such as an agar plate, where any bacteria from the swab will grow. They are also used to take DNA samples from, most commonly, the inner cheek. As well, 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.
Cotton swabs produced for home use are usually shorter, about three inches (7.6 cm) long, and usually double-tipped. The handles were first made of wood, then made of rolled paper, similar to lollipop sticks, which is still most common (although tubular plastic is becoming popular). They are often sold in large quantities, possibly 300 or more to a container.
One recent innovation is to use a special type of double-tipped cotton swab for over-the-counter drug application. These swabs have hollow tubular plastic handles, which are full of the medicine. Breaking one marked end of the swab breaks an air seal, allowing the medicine to saturate the cotton at the other end so that it can be directly applied with the swab (the cotton on the broken end is apparently there for the user's comfort when breaking the end).Millions of swabs are also sold by Distributors Choice Chemical for cleaning electronics and can be wet with solvents to help in the cleaning process.
Swabs exist in a wide variety of colors: purple, fuchsia, pink, green etc. However the cotton itself is white.
Cleaning the ear canal
Cotton swabs are primarly sold and used for the sole purpose cleaning one's ears. This, however, is not recommended by professionals because it could cause infection.[citation needed] another reason being that it may in fact cause the Ear wax to become compacted inside the ear or cotton can detach from the neck of the swab, impairing hearing, or permanently damaging the eardrum. In reaction to this problem, certain brands sell safety cotton swabs with bulging cotton ends to prevent them to enter too deep into small body orifices.
Nicknames and products
Though its true name is cotton swab, in North America it is most commonly called a Q-Tip. "Q-tip" has become a genericized trademark in much of Canada and the United States. The main producer and seller of the generic brand of cotton swabs is Unilever.
