Technical Details & Test Data

GreenGard™ LB Microbiology Challenge

Testing Report Wet Wipe Solution Challenge
GreenGard™ LB had its preservation properties tested in a wet wipe formula. It was tested at 2.00% usage rate at pH 5.00. A 28-day PCPC Preservative Adequacy Test Test was performed, in which the formula was challenge tested against Gram (+) & Gram (-) bacteria, yeast and mold inoculations. Recommended minimum criteria was a 99.9% reduction in bacterial colony forming units (cfu)/mL and a 90% reduction in yeast and mold cfu/mL within 7 days of inoculation, with reduction maintained for
the remainder of the trial.

Microbial species used for the challenge testing listed below:
Gram (+):S. aureus
Gram (-):P. aeruginosa, E. coli,
Yeast: C. albicans
Mold: A. brasiliensis

Results: Sample met the criteria for the preservative adequacy test. The formula showed a 99.99% reduction in cfu/mL within 1 day of inoculation for the Gram (+) & (-) bacterial and yeast species, and within 7 days of inoculation for the mold species.

GreenGard™ LB - PCPC Preservative Adequacy Test [wet wipe , pH 5.00]

Figure 1: GreenGard™ LB reduction of cfu/mL against bacteria, yeast and mold. Total kill was observed for bacteria and yeast after 1 day, and was observed for mold after 14 days. However, a 99.99% reduction in cfu/mL for mold was still observed after 7 days. Reduction maintained for remainder of trial.

Conclusion: GreenGard™ LB, when used at 2.00% in a mostly aqueous O/W emulsion between pH 4.50 - 5.00, is a broad-spectrum, germicidal preservative. It is highly effective against Gram (+) & (-) bacteria and yeast, and effective against mold.
