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.
Human body as a complex doesn't have short pH level interval. There are enormous difference among pH of different organs. Blood's average pH is 7,35-7,45, stomach's pH is 1,5-2, small intestine's pHÂ¨is alkaline, large intestine's pH is acidic (6 and lower).est Answer: The normal pH of blood running through arteries (large elastic-walled blood vessels that carry blood from the heart to other parts of the body) is 7.4; the pH of blood in the veins (vessels that transports blood to the heart) is about 7.35.
