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.
Blood pH is tightly regulated by a system of buffers that continuously maintain it in a normal range of 7.35 to 7.45 (slightly alkaline). Blood pH drop below 7 can lead to a coma and even death due to severe acidosis. This causes depression of the central nervous system. High blood pH (above 7.45) is called alkalosis. Severe alkalosis (when blood pH is more than 8) can also lead to death, as it often happens during last days or hours of life in most people who are chronically and terminally ill.
