Functions: DMDM Hydantoin is a controversial ingredient because of its formaldehyde properties. Although the releasing of formaldehyde is the process that makes the environment less favorable for microorganisms (source), this process is what makes it an effective cleanser and preservative in many beauty products.unctions: DMDM Hydantoin is a controversial ingredient because of its formaldehyde properties.

Anything above 7.0 is alkaline, anything below 7.0 is considered acidic. Human blood stays in a very narrow pH range right around ( 7.35 - 7.45 ). Below or above this range means symptoms and disease. If blood pH moves to much below 6.8 or above 7.8, cells stop functioning and the patient dies. The ideal pH for blood is 7.4.
Numerical Range. Normal blood pH is 7.4. Lower than pH 7.4, the blood is acidic, and higher than 7.4 the blood is basic, or alkaline. Large changes in blood acidity results in small changes in the pH.In other words, even if the pH moves only a little, that small amount can represent a significant change for the amount of excess or lost acid in the blood.he blood pH is a measure of the acidity of the blood. It stands for power of hydrogen and represents the concentration of hydrogen ions, which make the blood acidic. Acidic or alkaline blood can interfere with processes in the body and be both a result of disease and a cause of further problems.
