P h and shampoo

  1. 1. PH AND SHAMPOO By: Izzy Nuta
  2. 2. Hair structure  Your hair is a living thing  Hair is made up of mostly proteins, which proteins are made up of long chains of amino acids  The hair is dead material after it leaves its root (Boehm 1)
  3. 3. Function of Shampoo  There are different shampoo’s for certain types of hairs.  Wash the hair effectively.  Remove filth completely.  Not have any side effects or irritations to the skin and eyes.  To prevent dandruff.
  4. 4. Potential of Hydrogen (pH)  pH is a scale measurement of the acidity and basicity.  Human hair has the pH balance between 4.5 and 5.5  The pH of shampoo usually ranges from 5 to 11.  If the pH is too acidic, it will cause the cuticle to contract; if the pH is too basic, the cuticle will open.
  5. 5. Chemistry of Shampoo  There are four main ingredients in shampoos: cleaning agents, modifying agents, pH adjuster, and fragrance.  The main ingredient in shampoos is water.  The surfactant is another important ingredient in shampoos.  The surfactant helps to clean the hair and strips it of oil which is similar to what soap does.  Shampoo acts as a detergent for the hair.
  6. 6. Implications  Shampoo is an everyday household item that people use.  Shampoo is a meant to remove grease and dirt of hair.  Shampoo could cause damage to hair depending on the pH level of the shampoo and the frequency of use of the shampoo.  Foam actually does not do anything to hair but to satisfy the consumers
  7. 7. Summary  Need to know the frequency and how often to use shampoo depending on the hair type.  The most important ingredient needed for shampoo are surfactants.  There are four types: anionic, cationic, nonionic and amphoteric.  The basic chemistry of hair leads to the production of shampoo.
