There are tons of brands of antibacterial soaps in the soap industry, and some of them have a 99.99% chance of killing germs. There is one question most likely surrounding these brands: Do they actually work, and work effectively? This is the main question revolving around my experiment. Determining the effectiveness of 4 different soaps (Purell, Softsoap, Dial, and germ-X) will show how helpful these soaps really help us human beings.
The Purell antibacterial soap brand is a great soap that claims to destroy 99.9% of germs. Purell contains many important germ-killing ingredients: including ethyl alcohol and glycerin. According to an article by Chris Sherwood,
Purell is one of the most commonly used instant hand sanitizers on the market. Purell hand sanitizer is able to kill many of the bacteria and viruses on your hands by using a careful mixture of active and inactive ingredients.

According to the Purell company, "One of the major benefits of using ethyl alcohol over other germ killing agents is that bacteria have been unable to create a resistance to ethyl alcohol," (Purell Hand Sanitizer Ingredients, 2013). With that being said, Purell will always kill germs for someone that uses it frequently. It is always effective on germs no matter how much you decide to use it. Glycerin is used in many skin products. In Purell, it is used to moisturize skin and spread easier on the skin. It helps prevent dry and itchy skin, as well as helping dead skin cells fall off

Parents and teachers encourage children to wash their hands with soap and water after using the bathroom, touching dirty objects, and sometimes before eating. Next to every tissue box there will most likely be a bottle of hand sanitizer that kills 99.9% of germs. Both hand soap and hand sanitizer kill off the germs and bacteria that can cause infections and diseases. Which one works best? The purpose of this experiment is to show which is more effective, hand soap or hand sanitizer (Bjornsson). To prove this, Bjornsson writes up a lab using the growth of bread mold to help identify the results of both products (Bjornsson). I believe that hand soap works better than hand sanitizers because doctors remind us that we should wash our hands especially during flu season to keep us healthy. Therefore, the hypothesis for this lab is that the hand soap will be the better alternative and will slow down the growth of bread mold more than the hand sanitizer in this experiment.

Founded in 1886 by introducing medicinal plasters and antiseptic surgical dressings, Johnson & Johnson has grown to be one of the leading health care products company in the world. In its extensive history of over 125 years Johnson & Johnson’s product mix vary from pharmaceutical, personal care products, medical devices and diagnostics with the largest being pharmaceuticals.
Hand decontamination is the use of hand wash or alcohol rub that reduces the number of bacteria on the hands. Hand decontamination is also referred to as ‘hand hygiene’. Hand Hygiene is an integral part of nursing care, as effectively decontaminating hands significantly reduces the risk of pathogens being transferred from one surface to another, or from person to person (NICE, 2014). This means, that through practicing good hand hygiene, nurses can actively reduce the incidences of preventable healthcare associated infections, therefore improving the health and mortality of their patients.

Mouthwash for many people is something that is used everyday, gram-negative bacteria are very strong bacteria and are hard to kill with such structural properties and from investigating this I am able to see what form of mouthwash is better for the human mouth on killing such bacteria.

daily lives, for years. On the early history of chlorine, chlorine was first discovered back in the thirteen century and it was used first by the Swedish chemist Carl Wilem Scheele mentioned on the introduction in 1774. Most serious health threats are said not to be caused by chemicals, but by very infectious organisms or bacteria in water that we drink and use in our daily basis. Chlorine is a major disinfectant that is cheap and kills most of the serious disease-causing bacteria in the water. However, chlorine disinfection results in a wide variety of by-products. One class of chlorination by-products, known as trihalomethanes (THM 's), are suspected carcinogens. Because of concern about these by-products in the water supply, chlorine is now kept to minimum levels, and other methods of disinfection are being used more frequently. Chloramines form more stable disinfectants and pose less risk of harmful by-products, but cost more to use. Other methods focus on removing the organisms through coagulation, sedimentation, and improved filtration. The functions of chlorination are to disinfect water or wastewater, decolorize waters or fabrics, sanitize and clean surfaces, remove iron and manganese, and reduce odors. However, the odor of certain compounds, such as some phenolics, is aggravated through a reaction with chlorine. Certain soluble metals can be made insoluble through oxidation by chlorine (soluble Fe2+ is oxidized to insoluble Fe3+), making the metal easier to remove through sedimentation or
Detergent comes from the Latin word detergere meaning to clean, it is defined as a cleansing agent. Therefore, water itself is a detergent. This essay looks at soap and soapless (or synthetic) detergents. Both substances we use everyday and have a big market commercially, they effect everyone. Soaps are made from natural products and soapless detergents are produced chemically, each having advantages and disadvantages.
As long as the hand sanitizer contains at least 60 percent alcohol and is used correctly, then it does not matter which form of hand sanitizer is used. Hand sanitizers kill most, but not all of the bacteria and viruses on contact, but it does not work well when there is grime from cooking or gardening because the grime makes a barrier.
This 1899 advertisement for Pears ' Soap came from the poem written by the British novelist Robert Kipling, who wrote about the ideas of White Man’s Burden. The artists and the company were both clearly behind the idea with American Imperialism. The image was used to help make America jump in the bandwagon to step in where the Europeans left off and bring civilization to the uncivilized parts of the world.
Soap, or 'sapo' in Latin, is an age-old cleansing agent that dates as far back as ancient Babylon. Throughout time, soap has been a core element of laundry, household, and personal cleansing routines for many civilizations and although soap-making methods have evolved over time, it is still essentially a mixture of fats and oils that have been combined with an alkali. Origins Historians aren't in complete agreement about exactly when soap was discovered, yet there is evidence that the Sumerians - an ancient civilization that resided in Southern Mesopotamia, now known as south Iraq - used a soap-like substance to strip grease from cloth and wool before dying them. The substance, which archaeologists discovered in inscribed clay vessels, was slippery and the inscriptions on the vessels described how the Sumerians boiled ashes and fats to form it.
Rinse off the soap using clean water. In the event that you are not using running water from the tap, fetch another bucket/bowl of clean water to wash your hands with.
To test latherability, a small amount of the soap or detergent was added to a test tube and shaken. The latherability was measured by observing the amount of bubbles that formed. Dispersibility was then tested by again mixing a small amount of the soap or detergent with water. After shaken, the amount of oil globules that formed was observed. The pH of the soaps and detergents were then tested by mixing a small amount of the soap or detergent with water. A pH strip was used and compared to a pH chart to determine the pH of the samples. Cleaning ability was tested for the soaps and detergents by using a small sample of the soap or detergent to observe if it could clean small stains off the laboratory sink. A solubility test was also performed to determine what solvents dissolved the soap or detergent. Water, 1 M NaOH, 1 M hydrochloric acid (HCl), toluene, and acetone were the solvents that were used to test solubility. A small piece of the soap or detergent was added to five separate test tubes and each solvent was added separately and observed if dissolution occurred.
