pH balanced
Most people have heard the phrase pH balanced. Most people don't know what that means. products that clain to be pH balanced sell better because it sounds better. Then what does it really mean. Well Koos Veel M.D. has this to say:
On the packaging of shampoos, lotions and creams the term "pH balanced" often appears.
The pH of a liquid is a chemical term to indicate its acidity. This is measured by the amount of free hydrogen atomes and expressed by the pH. When the liquid has a pH of 1 or 2 it is very acid while a pH of 5 or 6 is very lightly acid. A neutral liquid has a pH of 7 and with a pH above 7 the liquid becomes "basic."
When a product is pH balanced it simply means that in the formulation chemical buffers were added so that the product has a constant pH or acidity.
Most products are made (pH balanced) at a PH of 7 or a little less.
That is not always the best way to go.The human skin and the human hair have a pH between 5 and 6. This means that the skin's surface is slightly acid.
Scientist know today that this acid environment is to prevent growth of bacteria and that this acidity is a protection against substances with a high pH.
The skin is covered with a complicated mixture of natural chemicals that have the ability to neutralize bases and to some extend also acids.
It has been proven that soaps of high pH ("basic soaps") can be very irritating for the skin and can temporarily destroy this natural, weakly acid barrier.
That is why shampoos, lotions and creams should have a pH of between 5 and 6 adjusted to the pH of the skin as is done in the Aruba Aloe skin care and hair care products.
