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.
What is normal? As humans, a normal pH of all tissues and fluids of the body (except the stomach) is slightly alkaline. The most critical pH is in the blood. All other organs and fluids will fluctuate in their range in order to keep the blood a strict pH between 7.35 and 7.45 (slightly alkaline).This process is called homeostasis.s humans, a normal pH of all tissues and fluids of the body (except the stomach) is slightly alkaline.
