Antibacterial Soap
Antibacterial soap is a soap which contains chemical ingredients that purportedly assist in killing bacteria. The majority of antibacterial soaps contain triclosan, though other chemical additives are also common. The effectiveness of products branded as being antibacterial has been disputed by some academics as well as the U.S. Food and Drug Administration (FDA). History The earliest antibacterial soap was carbolic soap, which used up to 5% phenols (carbolic acid). Fears about the safety of carbolic soaps chemical components on the skin brought about a ban on some of these chemical components. Triclosan and other antibacterial agents have long been used in commercial cleaning products for hospitals and other healthcare settings, however they began to be used in home cleaning products during the 1990s. Ingredients Triclosan and triclocarban are the most common compounds used as antibacterials in soaps. However, other common antibacterial ingredients in soaps include benzalkonium ...

Reeva Antibacterial Liquid Soap
Reeva Rebecca Steenkamp (; 19 August 1983 – 14 February 2013) was a South African model and paralegal. She modeled for ''FHM'' magazine and was the first face of Avon cosmetics in South Africa. Steenkamp once worked as the live roaming presenter for FashionTV in South Africa and starred in television advertisements for Toyota Land Cruiser, Clover "The One", Redds and Aldor Pin Pop. She was a celebrity contestant on the BBC Lifestyle show ''Baking Made Easy'' in 2012 and on '' Tropika Island of Treasure'' season 5 which aired on SABC 3 in February 2013. On Valentine's Day 2013, Steenkamp was shot dead by her boyfriend, Oscar Pistorius, at his home in Pretoria. He stated that he thought Steenkamp was an intruder hiding in the bathroom. Pistorius was found guilty of culpable homicide at a first trial, and was sentenced to five years in prison. On 3 December 2015, the Supreme Court of Appeal of South Africa overturned this conviction and instead convicted Pistorius of murder. ...

Chloroxylenol
Chloroxylenol, also known as ''para''-chloro-''meta''-xylenol (PCMX), is an antiseptic and disinfectant which is used for skin disinfection, and together with alcohol for cleaning surgical instruments. It is also used within a number of household disinfectants and wound cleaners. It is thought to act by disrupting microbial cell walls and inactivating cellular enzymes, and is less effective than some other available agents. It is available as a liquid. History Chloroxylenol was first made in 1927. It is on the World Health Organization's List of Essential Medicines. It is sold in a number of formulations and under a number of brand names, including ''Dettol''. Soon after it was created ''parachlorometaxylenol'' was then called ''PCMX'', but this was thought to be a poor name and it was renamed ''Dettol''. Then in 1932 it was marketed in Britain and in India. It had a white on green bottle with a white sword depicted. Properties Side effects are generally few but can include sk ...

Bacteria And Humans
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulp ...

Antimicrobial Resistance
Antimicrobial resistance (AMR) occurs when microbes evolve mechanisms that protect them from the effects of antimicrobials. All classes of microbes can evolve resistance. Fungi evolve antifungal resistance. Viruses evolve antiviral resistance. Protozoa evolve antiprotozoal resistance, and bacteria evolve antibiotic resistance. Those bacteria that are considered extensively drug resistant (XDR) or totally drug-resistant (TDR) are sometimes called "superbugs".A.-P. Magiorakos, A. Srinivasan, R. B. Carey, Y. Carmeli, M. E.

Disinfectant
A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical or chemical process that kills all types of life. Disinfectants are generally distinguished from other antimicrobial agents such as antibiotics, which destroy microorganisms within the body, and antiseptics, which destroy microorganisms on living tissue. Disinfectants are also different from biocides—the latter are intended to destroy all forms of life, not just microorganisms. Disinfectants work by destroying the cell wall of microbes or interfering with their metabolism. It is also a form of decontamination, and can be defined as the process whereby physical or chemical methods are used to reduce the amount of pathogenic microorganisms on a surface. Disinfectants can also be used to destroy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiseptic
An antiseptic (from Greek ἀντί ''anti'', "against" and σηπτικός ''sēptikos'', "putrefactive") is an antimicrobial substance or compound that is applied to living tissue/skin to reduce the possibility of infection, sepsis, or putrefaction. Antiseptics are generally distinguished from ''antibiotics'' by the latter's ability to safely destroy bacteria within the body, and from ''disinfectants'', which destroy microorganisms found on non-living objects. Antibacterials include antiseptics that have the proven ability to act against bacteria. Microbicides which destroy virus particles are called viricides or antivirals. Antifungals, also known as antimycotics, are pharmaceutical fungicides used to treat and prevent mycosis (fungal infection). Surgery The widespread introduction of antiseptic surgical methods was initiated by the publishing of the paper '' Antiseptic Principle of the Practice of Surgery'' in 1867 by Joseph Lister, which was inspired by Louis Pasteur ...

SARS-CoV-2
Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) is a strain of coronavirus that causes COVID-19 (coronavirus disease 2019), the respiratory illness responsible for the ongoing COVID-19 pandemic. The virus previously had a provisional name, 2019 novel coronavirus (2019-nCoV), and has also been called the human coronavirus 2019 (HCoV-19 or hCoV-19). First identified in the city of Wuhan, Hubei, China, the World Health Organization declared the outbreak a public health emergency of international concern on January 30, 2020, and a pandemic on March 11, 2020. SARS‑CoV‑2 is a positive-sense single-stranded RNA virus that is contagious in humans. SARS‑CoV‑2 is a virus of the species '' severe acute respiratory syndrome–related coronavirus'' (SARSr-CoV), related to the SARS-CoV-1 virus that caused the 2002–2004 SARS outbreak. Despite its close relation to SARS-CoV-1, its closest known relatives, with which it forms a sister group, are the derived ...

Hand Sanitizer
Hand sanitizer (also known as hand antiseptic, hand disinfectant, hand rub, or handrub) is a liquid, gel or foam generally used to kill many viruses/bacteria/microorganisms on the hands. In most settings, hand washing with soap and water is generally preferred. Hand sanitizer is less effective at killing certain kinds of illnesses, such as norovirus and '' Clostridium difficile,'' and unlike hand washing, it cannot physically remove harmful chemicals. People may incorrectly wipe off hand sanitizer before it has dried, and some are less effective because their alcohol concentrations are too low. Alcohol-based hand sanitizer that is ''at least'' 60% ( v/v) alcohol in water (specifically, ethanol or isopropyl alcohol/isopropanol (rubbing alcohol)) is recommended by the United States Centers for Disease Control and Prevention (CDC), but only if soap and water are not available. The CDC recommends the following steps when using an alcohol-based hand sanitizer: # Apply product t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benzethonium Chloride
Benzethonium chloride, also known as hyamine is a synthetic quaternary ammonium salt. This compound is an odorless white solid, soluble in water. It has surfactant, antiseptic, and anti-infective properties, and it is used as a topical antimicrobial agent in first aid antiseptics. It is also found in cosmetics and toiletries such as soap, mouthwashes, anti-itch ointments, and antibacterial moist towelettes. Benzethonium chloride is also used in the food industry as a hard surface disinfectant. Uses Antimicrobial Benzethonium chloride exhibits a broad spectrum of microbiocidal activity against bacteria, fungi, mold and viruses. Independent testing shows that benzethonium chloride is highly effective against such pathogens as methicillin-resistant ''Staphylococcus aureus'', ''Salmonella'', ''Escherichia coli'', '' Clostridium difficile'', hepatitis B virus, hepatitis C virus, herpes simplex virus (HSV), human immunodeficiency virus (HIV), respiratory syncytial virus (RSV), ...

Soap
Soap is a salt of a fatty acid used in a variety of cleansing and lubricating products. In a domestic setting, soaps are surfactants usually used for washing, bathing, and other types of housekeeping. In industrial settings, soaps are used as thickeners, components of some lubricants, and precursors to catalysts. When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned. In hand washing, as a surfactant, when lathered with a little water, soap kills microorganisms by disorganizing their membrane lipid bilayer and denaturing their proteins. It also emulsifies oils, enabling them to be carried away by running water. Soap is created by mixing fats and oils with a base. A similar process is used for making detergent which is also created by combining chemical compounds in a mixer. Humans have used soap for millennia. Evidence exists for the production of soap-like materials in ancient Babylon around 2800 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benzalkonium Chloride
Benzalkonium chloride (BZK, BKC, BAK, BAC), also known as alkyldimethylbenzylammonium chloride (ADBAC) and by the trade name Zephiran, is a type of cationic surfactant. It is an organic salt classified as a quaternary ammonium compound. ADBACs have three main categories of use: as a biocide, a cationic surfactant, and a phase transfer agent. ADBACs are a mixture of alkylbenzyldimethylammonium chlorides, in which the alkyl group has various even-numbered alkyl chain lengths. Solubility and physical properties Depending on purity, benzalkonium chloride ranges from colourless to a pale yellow (impure). Benzalkonium chloride is readily soluble in ethanol and acetone. Dissolution in water is ready, upon agitation. Aqueous solutions should be neutral to slightly alkaline. Solutions foam when shaken. Concentrated solutions have a bitter taste and a faint almond-like odour. Standard concentrates are manufactured as 50% and 80% w/w solutions, and sold under trade names such as BC50, ...

Triclocarban
Triclocarban (sometimes abbreviated as TCC) is an antibacterial chemical once common in, but now phased out of, personal care products like soaps and lotions. It was originally developed for the medical field. Although the mode of action is unknown, TCC can be effective in fighting infections by targeting the growth of bacteria such as '' Staphylococcus aureus''. Additional research seeks to understand its potential for causing antibacterial resistance and its effects on organismal and environmental health. Usage Triclocarban has been used as an antimicrobial and antifungal compound since the 1960s. It was commonly found in personal care products as an antimicrobial in soaps, lotions, deodorants, toothpaste, and plastic. about 80% of all antimicrobial bar soap sold in the United States contained triclocarban. In 2011 United States consumers were spending nearly 1 billion dollars annually on products containing triclocarban and triclosan. In December 2013, the Food and Drug Adm ...
