~ question about preservatives

[Guest guest]

Hello!

I make products for myself & family only, and I have a question

about presevatives:

I have Germaben II, but I saw the following preservative blend for

sale that doesn't use the olidinyl Urea-

" Our Preservative Blend is made with glycerin derived Propylene

Glycol, Methyparaben & Propylparaben. It is a broad spectrum

preservative effective against Gram-positive and Gram-negative

bacteria, yeast and mold and used in almost all forms of

cosmetic formulations. It is similar to Germaben II except our

blend does not have the formaldehyde releaser olidinyl

Urea. "

I would prefer to use this instead of what I have, but I'm clueless

if it would be " OK " or not. How important is the D.U. in making an

effective preservative? If it's not really necessary, then why is it so

popular (it's in most of the formulations I've looked at online, at

least)?

Sorry if this is a beaten-to-death topic, there's not really anyone

else I can ask.

tia,

V.
