Soap in Human Skin

     



     Soap is a sodium salt or potassium salt of long chain fatty acids having cleansing action in water. They are used as cleansing agents to remove dirt, oil from the skin and clothes. Examples : sodium stearate, sodium oliate and sodium palmitate formed using stearic acid oleic acid and palmitic acid.

Saponification method



    Saponification is a process that produces soap, usually from fats and lye using aqueous sodium hydroxide solution.

Soap in your skin
  • Soap is alkaline, which irritates sensitive skin, which is normally acidic. Alkaline skin degrades quickly as protease enzymes are activated that destroy the skin proteins.
  • It makes the skin dry.
  • It affects the structure of the skin.
  • It affects the good bacteria on your skin.
  • It can cause allergic reactions.
  • Soap forms scum when used with hard water (water that contains a high amount of calcium in solution). The scum stops the surfactant properties, so one tends to use more soap.
  • Soap leaves deposits of carbonate salts on the skin. This irritates the skin.
Good ingredients

    Glycerine is a plant-based cleanser that can seal moisture into your skin barrier without stripping your skin of oils.

    Natural exfoliants, such as finely milled black walnut shells, oatmeal, or ground apricot pits, can work to naturally remove dead skin cells.

Ingredients to avoid
    Avoid powerful antibacterial agents in your bar soap.

  • Triclosan  is a powerful antibacterial that was banned by the FDA in 2016.
  • Parabens are chemical preservatives that are meant to preserve the shelf life of cosmetic products.
  • If you have allergies, you may want to avoid products with “fragrance” or “perfum” on ingredient labels.

Queen Of Chemsitry

         Benzene ( C6H6)  is the 'Queen of chemistry'. Benzene is an organic compound with the chemical formula of C6H6. It is also considered a parent compound of the various Aromatic compounds. The properties of benzene is a colorless, flammable, and highly aromatic liquid with a sweet odor. In benzene, there are two carbon atoms in each carbon atom and one hydrogen atom. The C-C bonds in benzene represent the combination of single and double bonds in resonance structures of benzene.   Benzene Chemical Formula is C6H6   Benzene Molecular Weight is 78u    Benzene is a versatile organic compound  applied in the various chemical industries such as in the manufacture of plastics, rubbers, lubricants, and more. However, Benzene is toxic and carcinogenic and that is why it has some non-industrial uses. Here are some applications of structure of Benzene: Benzene can be used as a solvent in nonpolar substances such as oils, fats, resins, etc. It also helps in degreasing of the metals

                     Sugar is naturally in lots of foods like fruit, vegetables, milk, cheese, and even grains.

Fun Facts of Chemistry- part 1

  You can die from drinking too much water. Radioactive and nuclear elements actually glow in the dark. Glass is not a solid – glass is a liquid. Helium is lighter than air. Water is one of the elements which expands while freezing and according to scientists, water takes up 9% more volume when frozen in comparison to its liquid state.  Oxygen is said to be colourless but that is only applicable for the gaseous form. The solid and the liquid form of oxygen appear to be blue. The most expensive element is californium, it is used in industries. Copper is the only element which is naturally Antibacterial. Cloud is actually made of tiny drops of liquid. When the droplets gather and become heavy, that's when rain falls. You need to exceed temperatures of 1000 degrees Celsius to burn a diamond.
