TEST-PERFORMED: 
Preservative Effectiveness Test
Category 1C
BTS METHOD
M101.R2
REFERENCE
USP 23, 8th Supplement
SAMPLE PREPARATION:
The following organisms: Aspergillus niger, Candida albicans, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, were used to challenge the specimen for twenty-eight (28) days. Microorganism survival is monitored at fourteen (14) and twenty-eight (28) day intervals.

INTERPRETATION:
For Category 1C Products, the preservative is effective in the product examined if;

a) Not less than or equal to 1.0 log reduction from the initial count at 14 days, and no increase* from the 14 day count at 28 days is observed in the bacterial samples.

b) no increase* from the initial calculated count at 14 and 28 days is observed in the yeast and mold samples.
*No increase is defined as not more than 0.5 log10 unit higher than the previous value measured.

CONCLUSION:
The above test results meet the current USP criteria for Antimicrobial Preservative Effectiveness Test.
