Stock No. 9651, 9652, 9654, 9656, 9657, 9659, 9661, 7187, 2256, 2156, 9605, 9606, 3020, 9584, 3005, 9650 Color: Clear : Citrus Viscosity: 6,000-25,000 cps (gel) ph: Objective: Evaluation of irritation potential in humans. Description of Test: 21-Day Human Irritancy Assay. Method: The method is that summarized by Phillips et al. (Toxic and Applied Pharmacology 21: , 1972). The fresh materials are applied five (5) days weekly for twenty-one (21) days to the same site. Patches are not reapplied on weekends (or holidays); they remain in place for these periods. There are fifteen (15) days of reading, even when holidays intervene. Date: February 27, 1998 Results: Average score 0.05 (scale 0-4). Lower scores indicate lower potential for skin irritation and allergic contact dermatitis. Conclusion: Product has a low potential for skin irritation and allergic contact dermatitis. Human Repeated Insult Patch Test Objective: Determination of the dermal irritation and sensitization potential of the product. Description of Test: Human repeated patch test. Method: This study was conducted utilizing a standard protocol and a total of two hundred and fifteen (215) subjects. Prior to patch application, the test area was wiped with seventy percent (70%) ethanol and allowed to dry. The test material was applied under a semi-occlusive patch (Readi-Bandage ) to the upper back (between the scapulae) and allowed to remain in direct skin contact for twenty-four (24) hours. Patches were applied to the same site on Monday, Wednesday and Friday for a three (3)-week induction period. The sites were graded for dermal irritation and sensitization twenty-four (24) hours after removal of the patches on Tuesday and Thursday, and forty-eight (48) hours after patch removal on Saturday. Standard Dermal Scores (0-4+) were used to record dermal reactions. After two (2) weeks, the subjects were rechallenged and evaluated forty-eight (48) and seventy-two (72) hours after patch removal. Independent Laboratory: Clinical Research Laboratories, Inc., Piscataway, New Jersey. Date: April 30, 2002 Results: No dermal reactions were observed during the induction or challenge phases of the study. Conclusion: Test product did not demonstrate potential for eliciting a dermal irritation or sensitization. Efficacy Data In Vitro Objective: These tests were designated to evaluate the antimicrobial effectiveness of product formulations when challenged with a broad spectrum of microorganisms. Description of Test: Fifteen (15) second exposure kill studies were performed utilizing thirtyfour (34) challenge microorganisms. The challenge inoculum was introduced to the test product at time zero; a portion of the sample was removed and placed in neutralizing media at the appropriate time (15 seconds). Standard plate counting techniques were used to enumerate viable challenge micro-organisms.

Description of Test: Thirty-six (36) subjects were recruited and completed this evaluation. Baseline counts of the microbial skin flora of the hands of the subjects were performed utilizing a glove juice protocol. A standard surgical scrub wash was performed at least once by each of the subjects each day for five (5) days. A glove juice sampling procedure was performed at five (5) minutes post wash, three (3) hours post wash and six (6) hours post wash on days one (1), two (2) and five (5) after the first wash of the day. Additional scrubs without glove juice sampling occurred on days two (2), three (3) and four (4). Reference OTC TopicalAntimicrobial Products Tentative Final Monograph, Federal Register, Volume 43 (4): , Independent Laboratory: Skyland Scientific Services, Inc., Belgrade, MT. Conclusion: The results show good immediate and persistent antimicrobial effects of the product on the skin micro flora of the hands, in which the product was equivalent to or better than the reference product. Conclusion Chlorhexidine gluconate is very effective against both Gram-positive and Gramnegative bacteria, yeast and fungal microorganisms. Active Ingredient Chlorhexidine Gluconate (2% wt) Also Contains: Water Isopropyl Alcohol Surfactants Antimicrobial Surfactant, Cleaning 11
