E.Coli, Salmonella, Listeria, MRSA and the flu virus.
Procedure. 1. The independent variable for this experiment is the concentration of dettol disinfectant used – 25%, 50% and 75%. The dependent variable is the size of the inhibition zone which refers to the area free of bacteria). This is determined by measuring its diameter using a ruler.  Can be used on many surfaces in your home or as an anti-bacterial skin cleanser. Dettol's formula is proven to kill 99.9% of bacteria on surfaces, including E.Coli, Salmonella, Listeria, MRSA and the flu virus. Can be used on: 1  Drains. 2  Toilet Seats and handles. 3  Toilet bowls and brushes. 4  Bins. 5  Floors. 6  Work Surfaces. Dettol Disinfectant Liquid provides expert protection against harmful bacteria and can be used on many surfaces in your home for infection control purposes and for general disinfection. Dettol Disinfectant liquid can also be used for antibacterial skin cleansing, always use as directed. Share This Page. -. A number of disinfectant and antiseptic products are available under the Dettol brand including disinfectants for surfaces, antiseptics for use on the body, wipes and sprays. Here we will concentrate on the ‘core’ product-the liquid antiseptic, Figure 5. Figure 5: Dettol liquid antiseptic, contains chloroxylenol. Disinfectants kill microbes (bacteria, fungi and viruses) and are used on surfaces (such as worktops, sinks etc.) but not living things (such as skin) as they may harm them. Antiseptics also kill microorganisms but may be used on the body surface (skin) although not in the body (e.g. by mouth). Dettol is the trade name for a line of hygiene products manufactured by Reckitt Benckiser. It has been in use since before 1936, when it was used after surgery as an antiseptic.  Karen McCarthy. answered on 20 Nov 2013: Dettol is an antibacterial agent, which means basically that it has an ingredient in it that can kill or prevent the growth of bacteria. Bacteria are actually sensitive structures, and certain chemicals can damage their cell shape or metabolism, preventing them from surviving.  Dettol is one of those chemicals which we instantly recognise by its distinctive smell. It is an aromatic compound derived from phenol, which contains a significant chlorine atom, helping us in our continuous fight against unwanted bacteria. Dettol has some considerable advantages; from low toxicity, low metal corrosivity (important when sterilizing medical instruments), and is active over pH's 4-9. Despite being only slightly soluble in water it has a good solubility in alcohols (ethanol/propan-2-ol 50-87 g/100 ml) and pine oils. Although originally thought to kill bacteria by attacking multiple cellular targets, triclosan was recently shown to target a specific bacterial fatty acid biosynthetic enzyme, enoyl-[acyl-carrier protein] reductase, in Gram-negative and Gram-positive bacteria, as well as in the Mycobacteria. Triclosan is the active ingredient in a multitude of health care and consumer products with germicidal properties, which have flooded the market in recent years in response to the public's fear of communicable bacteria. Disinfectants are chemical substances used to destroy viruses and microbes (germs), such as bacteria and fungi, as opposed to an antiseptic which can prevent the growth and reproduction of various microorganisms, but does not destroy them. The most resistant pathogens are bacteria spores but some viruses and bacteria are also highly resistant to many disinfectants. All disinfectants are also, by their very nature, potentially harmful (even toxic) to humans or animals. They should be treated with appropriate care.
