Hey KK,

BTW, we expect people to use their real names when posting.

Net-etiquette.

" Germall Plus can effectively preserve cosmetic and personal care

formulations beginning at 0.025%. Typical usage levels of Germall Plus

range From 0.05% - 0.2%. Challenge data have confirmed that even at low

usage levels, Germall Plus can deliver broad spectrum antimicrobial

preservation. For products containing a significant amount of proteins

and/or complex ingredients, 0.2% of Germall Plus is recommended for

proper presentation. "

Since Liquid Germall Plus is a 40% solution of Germall Plus in

Propylene Glycol, the typical usage range for Liquid Germall Plus is

0.125% to 0.5%. You can do the math but here are numbers:

0.05% Germall Plus = 0.125% Liquid Germall Plus

0.1% Germall Plus = 0.25% Liquid Germall Plus

0.11% Germall Plus = 0.275% Liquid Germall Plus

0.12% Germall Plus = 0.3% Liquid Germall Plus

0.13% Germall Plus = 0.325% Liquid Germall Plus

0.14% Germall Plus = 0.35% Liquid Germall Plus

0.15% Germall Plus = 0.375% Liquid Germall Plus

0.16% Germall Plus = 0.4% Liquid Germall Plus

0.17% Germall Plus = 0.425% Liquid Germall Plus

0.18% Germall Plus = 0.45% Liquid Germall Plus

0.19% Germall Plus = 0.475% Liquid Germall Plus

0.2% Germall Plus = 0.5% Liquid Germall Plus

Paw Made says that Liquid Germall Plus is " [p]roven effective at low

usage rates--.1% - 1%, depending on your application. Be sure you test

for effectiveness in your specific use. "

I am quite sure that Liquid Germall Plus will be a very effective

preservative at 1%. But I would be concerned about the safety issue.

Why did the manufacturer put a limit on the usage rate?

I wonder if Paw Made Soaps or ISP/Sutton have any safety data for 1%

Liquid Germall Plus. Who knows??

Personally, I think using bio-active ingredient, like Liquid Germall

Plus, above the maximum level recommended by the manufacture is

exposing yourself to liabilty.

Don't forget that " [e]ach ingredient used in a cosmetic product and

each finished cosmetic product shall be adequately substantiated for

safety prior to marketing. Any such ingredient or product whose safety

is not adequately substantiated prior to marketing is misbranded unless

it contains the following conspicuous statement on the principal

display panel:

Warning--The safety of this product has not bee

determined. "
