METALWORKING FLUID ADDITIVES DIVISION …

1 Product Information METALWORKING FLUID ADDITIVES DIVISION . MERGAL 174. Broad spectrum bactericide for METALWORKING FLUID Applications EPA Registration No. 5383-11. Description Water dilutable soluble oil, semi-synthetic and synthetic METALWORKING fluids are highly susceptible to the growth of microorganisms. Microbial contamination can result in slime generation, gas formation, malodors and the reduction or drift of pH in the FLUID concentrate and the working dilution. This contamination can diminish FLUID performance and system efficiency, which can increase costs, decrease tool life, reduce productivity, and cause machine shut down.

2 The use of Mergal 174, a proven high quality preservative to control biodeterioration, will help maintain product functionality and increase the life of the METALWORKING FLUID . Application/ For use during manufacturing in concentrates and for use in post addition applications. Use Cost effective Highlights Broad spectrum of anti-microbial activity Ease of incorporation Excellent freeze-thaw stability Long term efficacy Physical The following are typical properties of Mergal 174; they are not to be considered product Properties specifications.

3 Active Ingredient: 2[(Hydroxymethyl) amino] 98%. Appearance: .. Clear amber liquid Color (Gardner) 4 Max. Specific Gravity, 25 C .. Viscosity (Gardner).. L Max pH (as is) .. ~ Solubility .. Completely soluble in water Antimicrobial The following are examples of the broad range of organisms against which Mergal 174 has Activity demonstrated preservative efficacy: Gram Negative Bacteria Gram Positive Bacteria Pseudomonas aeruginosa Bacillus subtilis Pseudomonas fluorescens Staphylococcus aureus Enterobacter aerogenes Streptococcus faecalis Escherichia coli Desulfovibrio desulfuricans Proteus vulgaris Serratia marcescens Page 1 of 4.

4 Mergal 174 is a liquid, organic broad spectrum preservative designed for use in both the Function/. concentrate and working dilutions of soluble oil, semi-synthetic and synthetic METALWORKING FLUID Activity systems which may be subject to microbial degradation. Formulating Mergal 174, at appropriate use levels in both laboratory and field evaluations, inhibits the growth of microorganisms. Furthermore, products protected with Mergal 174 can generally resist long term Considerations repeated challenge by microorganisms.

5 When used in METALWORKING FLUID concentrates and working dilutions at application use levels of . (1000 - 3000 ppm), based on the weight of the working dilution, Mergal 174 will protect against a broad range of gram positive and gram negative bacteria. The level of Mergal 174 required for optimum effectiveness is dependant on the composition and end use application of your specific product formulation. Regulatory Toxicity Considerations Acute Oral Effects: LD50 (oral, rat-male)-1620 mg/kg; LD50 (oral, rat-female)-1956 mg/kg Acute Skin Effects: LD50 (dermal, rabbit) >2000 mg/kg.

6 In an acute dermal irritation study all treated sites were normal at 24 hours. (Irritation score ). Acute Eye Effects: Severe irritation and corrosive (rabbit). Corneal damage may be irreversible if not washed from eyes promptly Acute Inhalation Effects: LC50 (rat, 4 hr)-620 mg/m3. Subchronic Effects and Other Studies 13 week dermal toxicity (rats) Groups of 10 male and 10 female Sprague-Dawley rats were dosed daily for 13 weeks via the dermal route at doses of 0, 50, 250, and 1000 mg/kg/day. Overall, no treatment effects or systemic toxicity were seen at each dose.

7 Teratogenicity (rats) Groups of 25 Sprague-Dawley rate were dosed daily via gavage from day 6-16. inclusive of gestation, at dosages of 0, 100, 250, and 500 mg/kg/day. No effect was seen on the dam or conceptus at dose levels of up to 250 mg/kg/day. Mutagenicity testing (mice) Micronucleus test in bone marrow; this product does not cause the production of micronuclei in the bone marrow of male and female CD-1 mice. Unscheduled DNA Synthesis This product is not genotoxic; it does not cause unscheduled DNA. synthesis in rat hepatocytes.
