Water (H2O) is a good solvent because it is partially polarized. The hydrogen ends of the water molecule have a partial positive charge, and the oxygen end of the molecule has a partial negative charge. This is because the oxygen atom holds on more tightly to the electrons it shares with the hydrogen atoms. The partial charges make it possible for water molecules to arrange themselves around charged atoms (ions) in solution, like the sodium (Na+) and chloride (Cl−) ions that dissociate when table salt dissolves in water.

Hydrogen bonds contribute to a property of water called cohesion or the tendency of water molecules to stick together.

Hence the boat conformer is able to dissolve in water but stabilizes soon and turns into the chair conformer making it non-polar and separating it from water.

In the article, they came up with the idea of gelling agents which is a chemical used to solidify any kind of spilled oil, making it easier to collect. Using the motion of the waves and sea, the gelling agent turns the oil into a rubbery material that can be easily removed from the water with nets, vacuuming, suction, devices or skimmers. This method helps clean the water without taking a lot of the water with it since when it solidifies you just pull out the chunks of oil instead of taking a lot water with it like if you were to try the hay or fleece

NaCl is ionic ,Crisco is polar,and Oil is nonpolar These substances are all different because they are not the same compound.Which means they will react different while testing. For example NaCl is the only one out of these three to be soluble in water.Crisco and Oil is not soluble in water.Oil is the liquid and it is nonpolar. This mean that it will only be soluble in in nonpolar substance.Crisco is between ionic and nonpolar that means it is polar.According to the powerpoint nonpolar substance will only dissolve in nonpolar liquids.

In the fall of my junior year, while attending a Wella hair product education class, I discovered that I could combine my love of cosmetology and my interest in chemistry by becoming a cosmetic chemist. Over the past two years my passion for cosmetology has grown. I believe that I will always be involved in cosmetology in some capacity. By attending a cosmetology program I have been given a good foundation in the cosmetic chemistry field. In order to formulate successful products one needs to do a lot more than understand product formulation. One needs to consider the structure of the hair, what the product will do to strengthen the cortex, how it will affect the color under the hair’s cuticle. I see my cosmetology education as a unique tool that help me along the way to reach my

These sulfates are used to obtain the foaming effect that most shampoos, skin cleansers and other cosmetic products produce. These sulfates are also used in detergents and other household cleaning products. Their wide use is dependent on that they are excellent at stripping oils and dirt from skin and hair; which explains their wide use in cosmetic and household cleaning products.

Thousands of people utilize cosmetics with nanoparticles everyday. With various nanoparticle cosmetic products out on market, the introduction of nanoparticles to consumers evinces promising progress in climbing its way towards competing with parabens as a better option.

Pathogens on the surface are eliminated physically by disinfectants. The mode of operation comes in the form of chemicals, diluted or undiluted for cleaning and by heating; we have noticed this process used in the milk preservation through pasteurisation whereby milk is heated at a very high temperature to kill pathogens. The application of disinfectants varies widely in use for the different settings. For healthcare cleaning to control and keep out pathogens, ethanol is the number one choice used to disinfect and sanitise floors, operation surfaces and surfaces touched the most by people like doors and door closing aids. The liquid based disinfectant normally gets rid of bacteria if it is in the right dilutions or measurements. There are iodine and chlorine based disinfectants both targeting pathogens. The latter is generally used in water treatment and food hygiene and the former widely used for making surgical instruments to render them free from pathogens, thus sterilisation. Antimicrobial

Know your skin sort. Knowing whether you have sleek, ordinary, dry, or even delicate skin will figure out what sort of item you ought to search for when purchasing a purifying item from your nearby store or drug store. The primary two classes of treatment are those with benzoyl peroxide and those with glycolic acid.

A surface active agent, also known as a surfactant is a substance that surrounds the inner surface of the lung and consists of four proteins and six phospholipid fats that are manufactured inside of the lung of the human body, however this substance can also be created artificially. The four proteins include the hydrophilic or water attracting proteins SP-A and SP-D and the opposite hydrophobic or water repelling proteins, SP-B and SP-C. The main purpose of a natural surfactant found in the body is to decrease the amount of surface tension of fluid (attraction of surface particles found in a liquid) that can be found in an organ. In the lungs for example this is achieved by securing the small air sacs inside of the alveoli (lungs).

Solid soap, because of its reusable nature, may hold bacteria acquired from previous uses. Yet, it is unlikely that any bacteria are transferred to users of the soap, as the bacteria are rinsed off with the foam.

Creams are known to be divided into a few definition based on its function. One of the definition are describing a thick white or pale yellow fatty liquid that usually rises on the top of the milk if we left the milk undisturbed for a long time. Besides that it is also defined as a very thick liquid or soft substance that is rubbed into the skin to make it softer or as a medicament for the skin (Merriam Webster). Cream also exists in the form of facial cream, hair cream and in a lot of forms and serves different purposes and function. It is their specific ingredients that differs the creams available in the industry. The basic formulation of the cream is water, oil and emulsifying agent. Cream which are being formulated usually comprise of separating and non-separating cream. Separating creams are creams which will separate into oils and water when left for a certain time meanwhile the non-separating creams will ensure the formulation stays together in place. All these factors are the function of adding emulsifying agents. They are responsible in making the cream that will combine them together completely or for a certain period of time. Therefore a stable emulsion is the main key in making a good lotion (DIY Cosmetics). Some of the creams available in the market are cosmetic creams, grooming creams, food industry creams and also pharmaceuticals cream. Pharmaceutical creams

The term emulsifiers alludes to any ingredient that keeps disimilar to substances (such as oil and water) from isolating. Many cosmetic products depends on emulsions - small droplets of oil dispersed in water or small droplets of water dispersed in oil. Since oil and water don't mix no matter how much you shake, mix, emulsifiers are added to change the surface tension between the water and the oil, producing a homogeneous and well-mixed product with an even texture. Examples of emulsifiers used in cosmetics include polysorbates, and laureth-4.(Professor Ben Selinger,2016)
