Position Paper on Registration Review of Silver Compounds 

December 12, 2012 

Abstract 

The Silver Task Force North America maintains that the interests of the public, the 

Environmental Protection Agency, and registrants of silver-based antimicrobials would 

best be served by a common data call-in for all silver-based antimicrobials. The Task 

Force bases its position on the rationale that all silver-based antimicrobials function by 

the release of silver cation as the biologically active moiety. Although there are several 

forms of silver-containing active ingredients under review, the active component of 

toxicological interest for risk assessment purposes for all EPA registered, silver based 

products is the silver ion. 

Background 

The Silver Task Force North America (STFNA or Task Force)1 is composed of 32 

companies that have taken an interest in silver-based antimicrobial products. In 

addition to registrants of silver-based technical grade active ingredients and formulated 

products, the Silver Task Force North America is comprised of companies that have or 

are developing silver-based antimicrobial technologies as well as consulting firms with 

extensive experience in representing silver-based antimicrobials in the United States 

and around the world (See Attachment 1 for a list of STFNA members). The common 

factor among this diverse group of companies is their expertise in the manufacture, use, 

and marketing of silver-based antimicrobials. Their common goal is to share this 

expertise with the U.S. Environmental Protection Agency (EPA) and work together with 

the EPA to ensure that the current re-evaluation of silver-based antimicrobials 

addresses all relevant data gaps and concerns in a manner that best utilizes the finite 

resources of both the Agency and industry. 

In the fall of 2007, the EPA first met with silver registrants to discuss the registration 

review process for silver products. There was recognition by industry at that time that 

pooling the collective knowledge of the silver registrants made eminent sense since it is 

the opinion of much of industry that all silver antimicrobials act via the silver ion. An 

organizational meeting of the U.S. Silver Task Force was held in the summer of 2009 

and the U.S. Silver Task Force held its inaugural meeting on October 14th of that year. 

The first task of the group was to respond to the EPA Preliminary Work Plan for the 

review of silver-based antimicrobials published in June of 2009. The Task Force 

identified a number of key issues. Among these were:

December 12, 2012 

 Use of bridging data between the different silver actives. Since all silver 

products rely on the release of silver ions to achieve their antimicrobial effect, this 

potentially allows for one representative test substance; 

 The environmental fate of silver-based antimicrobials being governed by the 

chemistry of silver/silver ions; and 

 Certain proposed exposure, toxicity, and environmental studies would not add to 

the body of knowledge but would tie up resources of both the Agency and 

industry that could be better directed to other issues. 

Over the following thirty months the U.S. Silver Task Force, working in co-operation with 

the EPA, was able to show that the dermal exposure data requirements as outlined in 

the original draft of the Registration Review were not necessary. The U.S. Silver Task 

Force also prepared a position paper on environmental fate and ecotoxicity and detailed 

comments on the draft Registration Review to help the EPA better understand and 

address key issues. 

The U.S. Silver Task Force has continued to work with the Agency since the release of 

the first set of Data Call-In notices (DCI) for silver-based actives issued February 29, 

2012. The U.S. Silver Task Force is already assisting the Agency in collecting data on 

the particle size and distribution of silver-based actives. Some of the members of the 

U.S. Silver Task Force that have silver zeolite products met with the Agency on April 18, 

2012, to discuss the DCI. During the meeting EPA acknowledged that it is still 

evaluating how to finalize the categorization of silver-based products and whether to 

issue multiple DCIs for each of the types of silver (silver and silver salts, silver zeolites 

and nanosilver) or a single revised DCI that specifies which data is required for each 

category, which studies can be bridged between the categories, and which data are 

specific for each separate category. 

EPA also acknowledged that from a historical perspective, the Agency has taken an 

inconsistent approach to the registration of the various silver products containing 

various forms of silver. However, it was agreed that the Registration Review process 

provides an opportunity for EPA to make consistent the approach and evaluation of all 

silver products. At that meeting the U.S. Silver Task Force offered, and was pleased 

that the Agency welcomed, that the U.S. Silver Task Force provide recommendations in 

regards to this process. The EPA and registrants will benefit from a common 

understanding of the various forms of silver contained in currently registered products 

and a categorization scheme for those silver forms that permits use of newly generated 

data to address hazard characterization and risk assessment needs broadly. 

In April of 2012,several members of the U.S. Silver Task Force realized the need for a 

more permanent organization under which corporations could generate data in 

response to the various silver Data Call-In Notices. In August of 2012, the Silver Task 

Force North America (STFNA), an unincorporated nonprofit association, was formed. 

The STFNA carefully reviewed the wide variety of silver compounds covered by the 

Registration Review. As a result the STFNA has prepared this position paper to 

demonstrate that, irrespective of the delivery method, be it silver salts, silver zeolites or

silver metal, the common biologically active moiety for silver-containing antimicrobials is 

silver ion and that data requirements should be based on this knowledge. Recognizing 

the commonality of the silver ion should motivate EPA to consolidate its DCI activities to 

take advantage of efficiencies and economies for both itself and registrants of silver 

compounds. The Task Force suggests issuing a new silver DCI for all silver-based 

actives based on identification of silver ion as the biologically active moiety. This will

conserve Agency and industry resources by reducing both the workload and the 

repetition of testing and complete the review of silver-based actives in a more timely 

fashion. 

Should issuing a new DCI for all silver compounds be administratively impractical or 

undesirable, the Task Force suggests adjusting the call-in deadlines for silver 

compounds to place all respondents on a common schedule. While the Task Force 

recognizes that the Agency historically has distinguished silver compounds by active 

ingredient designation or other means of categorization, this proceeding will 

demonstrate that the focus should be on silver ions and that the historical categories are 

arbitrary (and in some cases erroneous) and no longer necessary as the Agency‟s focus 

shifts to hazard and risk assessment for the silver ion. 

A Rationale for Focus on Silver Ion for Risk Assessment 

There are currently some 135 registered silver antimicrobial products. Of these, 106 

describe their active ingredient as “silver,” PC Code 072501 – that is, metallic silver, 

CAS# 7440-22-4. These include all but one of those registered in the four decades 

before 1996 and the majority of those registered since. Although many of these 

products are identified as having metallic silver as the active ingredient, most may be 

more accurately described as various salts, glasses, and ion-exchange carriers of silver 

in the form of silver ions. Three years ago Ionic silver Ag(1+), CAS# 14701-21-4, 

received its own PC Code ,072500, and the first three products were registered under 

this code in late 2009. Creation of this new PC Code, apparently by the Agency on its 

own initiative, suggests EPA already recognizes the validity of adopting a new focus on 

the silver ion. 

Historically the Agency has taken the position that some silver antimicrobials require 

special scrutiny because their antimicrobial activity differs from “conventional” or “bulk” 

silver. However a careful examination of publicly available information for registered 

silver antimicrobials, including the label information in NPIRS data bases, patents, and 

manufacturers‟ descriptive/promotional materials, shows that all of the silver 

antimicrobials, including those comprised of metallic silver, derive their antimicrobial 

efficacy from the release of silver ions Ag(1+). 

The STFNA is aware of the Agency‟s concerns about “nanosilver” and that some 

ultrafine particles may also exhibit size-related or morphological effects. Such effects 

occur in addition to, not instead of, the release of silver ions. Further, a recent study2

demonstrates that silver nanoparticles lose their activity against E.coli when they are 

synthesized and maintained anaerobically, and are thus unable to generate silver 

cations by oxidation. Under normal circumstances metallic silver surfaces are in

equilibrium with silver ions. “Conventional” or “bulk” silver has no chemical or 

antimicrobial activity except via ions. 

It seems fair to conclude, therefore, that registration of so many products as simply 

“silver” is largely a regulatory artifact reflecting an earlier understanding of the 

antimicrobial activity of silver. Reconsideration focused on the role of the silver ion 

is appropriate “to ensure that each pesticide registration is based on current

scientific knowledge regarding that pesticide, including its effects on human health 

and the environment.”3

Among metal ions, the silver cation Ag+ has a high redox potential. It is a very “soft” 

Lewis acid that reacts strongly with Lewis bases, such as sulfur. It is a potent 

antimicrobial even at very low concentrations, often at the level of micromoles per liter 

(μM/L). This “oligodynamic” (inelegantly, “few-powerful”) effect of silver was first noted 

by Nägeli, in 1893. 

As part of its effort to prepare a thoughtful and comprehensive response to EPA‟s initial 

implementation of the Registration Review process, the Task Force has examined the 

full range of registered products covered by the Review. Attachment 2 lists all currently 

registered products according to their chemical structure as related to ion release. 

There are various mechanisms through which these materials release the silver ions 

responsible for their effectiveness, including oxidation, dissolution, and elution. Each of 

these is briefly described below: 

(1) Oxidation: Metallic silver Ag(0) releases silver ions by oxidation ( Ag Ag+

 + 

e

-

 ). Metallic silver antimicrobials include silver-plated nylon filament for 

antimicrobial textiles; particulate silver for material-preservative applications; 

silver deposited by reduction in activated carbon or ceramic water filtration 

media; and colloidal silver, used widely in conjunction with chlorine in swimming 

pools but also in antimicrobial, disinfecting, and sterilizing sprays and solutions. 

Ion concentrations are on the order of 2 μM for swimming pool maintenance up 

to 0.5 mM for disinfecting sprays. 

The oxidation of silver must be balanced by a corresponding reduction of some 

other moiety which accepts the electron – as, for instance, oxygen (O2 + 2e- 

2O- ; and thus 4Ag + O2 2Ag2O). Therefore the rate of release of silver ions 

and the end product of oxidation depend not only on the metal itself and its 

configuration but also on what else is present on the metallic surface and in the 

air or water in contact with it. 

(2) Dissolution: Salts and other dissolving forms of silver release silver ions into 

water by dissolution (disassociation, deliquescence) and include materials with a 

very wide distribution of solubilities and configurations. The range of applications 

is also broad, including many material-preservative uses as well as antimicrobial 

sprays and solutions. The rate and extent of dissolution depend not only on the 

solubility of the silver compound itself but also on what else is in the water. The 

4 of 18

Position Paper on Registration Review of Silver Compounds 

December 12, 2012 

presence of other dissolved substances reduces the rate and extent of 

dissolution. 

Dissolving forms include silver glasses, materials preservatives used by 

incorporation into organic matrices. These specialty glasses release silver ions 

by dissolving very slowly into moisture on the polymer surface. In the most 

recently registered silver glass product (86101-2) the Agency has recognized 

silver ion Ag(1+), 072500, as the active ingredient rather than “silver,” 075201, as 

was the case for the older silver-glass products. 

In further confirmation of the role of the ion, the active ingredient in the sixth 

(EPA Reg. No.72977-6) in a series of silver dihydrogen citrate products is 

identified as silver ion Ag(1+), PC Code 072500; the preceding five products, all 

from the same manufacturer and incorporating the same ion-stabilization 

technology, identified “silver,” PC Code 072501, as the active ingredient. 

(3) Elution: Ion-exchange carriers are used almost exclusively as material 

preservatives as means to incorporate silver ions into otherwise incompatible 

organic matrices (fibers, plastics). These materials carry silver ions Ag(1+) 

electrostatically adsorbed, not chemically bound, within their usually porous 

molecular structure. When exposed to moisture these substances elute silver 

ions in exchange for other positive ions in the water (H+, Na+, etc.) which replace 

the electrosorbed silver within the carrier structure. In contrast to the salts and 

other dissolving forms of silver, therefore, the rate and extent of elution from ionexchange carriers are enhanced by the presence of other cations in water, with 

more and faster elution into, for instance, physiological saline than into deionized 

water. Elution is restricted and useful life extended by slow diffusion of ions 

within the carrier. 

In addition to materials preservative applications there is limited use of ionexchange carriers in water filters, humidifiers, dental water lines, and water 

softeners; in the latter case (EPA Reg. No.59454-3), the active ingredient is 

again identified by the EPA as silver ion Ag(1+), PC Code 072500. 

While these materials may differ in their mechanisms of action, the common and 

characteristic element, release of silver ion, should predominate for initial risk 

assessment purposes. To assist in EPA‟s Evaluation, Attachment 3 lists use and usage 

information for each of the products in Attachment 2 to show the predominant areas of 

usage for each type. Attachment 4 rearranges the same information to show that usage 

of silver antimicrobials falls into just five areas: (1) water treatment, mainly swimming 

pools and drinking water; (2) medical and dental applications; (3) liquid cleaners (for 

spray or mopping); (4) materials preservatives, the largest and broadest group; and (5) 

a very small group of agricultural uses for cleaning of equipment and premises. 

In the following we examine “special cases” of silver compounds which the Agency has 

previously identified as being “not chemically similar,” or otherwise requiring separate 

treatment from “silver and silver salts.” For these cases, too, the Task Force suggests 

5 of 18
Silver Task Force North America 

Position Paper on Registration Review of Silver Compounds 

December 12, 2012 

that the initial and primary focus should be the silver ion as the moiety responsible for 

antimicrobial efficacy. Only after completing that first-order assessment should the 

Agency consider the need for and value of extending its assessment for these types of 

products. 

Zeolites 

The letter accompanying the DCIs issued on February 29, 20124 stated that, “EPA 

believes that some of the products associated with the DCI(s) may contain “zeolite” 

active ingredients that are not correctly identified on the product labeling and/or 

Confidential Statements of Formula (CSF).” However, the registrants of all of the 

zeolite-based products, all members of the STFNA, met with the Agency in October 

2010, to identify themselves and discuss the products, and have identified these 

materials correctly in their CSFs, as well as on virtually all of their labels, as shown not 

only in NPIRS, but also in Table 1 of the Preliminary Work Plan.5

 The Task Force is 

confident that no previously unknown zeolite products will have emerged in response to 

the February 29, DCI letter. If the Agency‟s intent is to include other ion-exchange 

carriers or other chemistries under the “zeolite” rubric, it needs to redefine its 

terminology. 

That said, the zeolite registrants are pleased to have had the opportunity to meet with 

the Agency to discuss and document the structure and toxicity of man-made zeolite A.6

The Silver Task Force appreciates the Agency‟s consequent agreement to bridging of 

data among products based on man-made zeolite A,7

 and understands that this 

agreement was later extended to include two new products based on zeolite X. The 

following comments are to supplement the 2010 discussion, to introduce recent 

literature, and to re-emphasize that the antimicrobial activity of zeolite-based silver 

antimicrobials, as well as any health or environmental concerns, are to be attributed to 

silver ions and not to their adsorption on the inert carrier or to the carrier itself. 

The term zeolite is a well-defined chemical/mineralogical term referring specifically to 

tecto-alumino-silicates. However it appears that the Agency may have been using the 

term to refer more broadly to ion-exchange compounds in general. The Final Work Plan 

for the silver Registration Review stated that, “At this time, the Agency has concluded 

that zeolite-based silver compounds are not chemically similar to silver or silver 

salts”.

8

This conclusion, initially reached by the Agency in 20049, appears to be based 

primarily on a 90-day toxicity study in beagles for Antimicrobial Alphasan® RC 2000 

(EPA Reg. No.11631-3). This product is a silver sodium hydrogen zirconium phosphate 

(Ag-SHZP) made by exchanging silver ions for some of the sodium in a precursor 

zirconium phosphate and is not a zeolite.10Among the findings of the study were 

decreased body weight gain, elevated alkaline phosphatase, and thymic atrophy. An 

NOAEL of 400 mg/kg/day was set. Since this particular product contains 10% silver by 

weight, this is equivalent to 40 mg/kg/day of silver ion, which for humans would be 8000 

times the oral RfD for silver, which is 0.005 mg/kg/day.11,12

Although zirconium phosphate is an ion-exchange carrier, it is not zeolite. The structure 

of the AlphaSan zirconium phosphate antimicrobials is unclear13, but zirconium

Position Paper on Registration Review of Silver Compounds

phosphates are generally lamellar (not cage-like) structures of oxides of zirconium and 

phosphorus and are thus phyllo- rather than tecto-alumino-silicates. The precursors of 

both silver-zeolites A and X are EPA-recognized non-food inerts.14Zirconium phosphate 

is not, though zirconium oxide is listed in NPIRS as an active ingredient for pesticides 

(PC Code 79090 – no current registrants). Not only is there no solid basis for 

extrapolating findings from zirconium phosphate to zeolite, but the findings for the high 

dosage of Ag-SHZP cited in the EPA 2004 memorandum are strikingly similar to those 

reported more recently for a much smaller dosage (9 mg/kg/day) of silver acetate – an 

ionic solution – in rats.15 The beagle findings are more persuasively attributed to the 

silver ion itself than to the ion-exchange carrier. 

Finally, although silver zeolite, silver-zinc zeolite, and silver-copper zeolite (as well as 

Ag-SHZP) each have PC Codes and CAS numbers, none of these terms or numbers 

sufficiently defines the respective material. All are made by replacing some portion of 

the sodium in their precursors with silver ions. In “silver zeolite,” for instance, silver 

content can vary from effectively none to 22% by weight. At present the actual silver 

content is shown on the labels. The suggestion that such products should instead be 

registered as 100% silver zeolite, for example, would be to eliminate information 

required by users to evaluate both the relative effectiveness and the comparative 

economics of these products, not to mention the degree of any risk found to be 

associated with silver. As the active moiety is in fact the silver ion, this is the essential 

component to be mentioned in the label description16

. 

Small Particle Silver 

The Silver Task Force North America appreciates that EPA has ongoing concerns about 

the data required to assess the risks of small silver particles. The view that a unique 

dataset is required to assess the risks of small particle, or nanoscale, silver is derived 

largely from the recommendations of the 2009 FIFRA SAP on nanosilver which 

questioned whether there was sufficient data to support bridging arguments across 

silver compounds. 

An enormous amount of new information has been generated in the intervening three 

years. Google Scholar currently shows 13,800 new journal articles published from 

2009 to the present day containing the key word “silver nanoparticles.” Dozens of 

these papers contain new findings that directly address „data gaps‟ that were perceived 

to exist in areas such as aquatic toxicity17,18,19,20,21,22,23,24,25,26, mammalian 

toxicity15,27,28,29,30,31, and environmental fate32,33,34,35. Furthermore, new information 

about the existence of nanoscale and colloidal silver among long-registered silver 

products36, as well as the release to silver nanoparticles from macro silver objects37

, 

calls into question some of the core assumptions that underpinned the SAP review, 

including that idea that nanoscale silver is new and that human exposure to „bulk‟ 

metallic silver throughout history only resulted in exposure to silver ions rather than to 

nanoscale particles. 

As new data has been generated, the fundamental question of the silver ion‟s role in 

silver particle toxicity, the so-called 0-hypothesis38, has been examined in a number of 

7 of 18
Silver Task Force North America 

Position Paper on Registration Review of Silver Compounds 

December 12, 2012 

systems2,15,20,26,31,39. The most recent results are unequivocal that the silver ion is the 

active moiety responsible for the antimicrobial action of silver particles. Many other new 

research findings, using soluble silver salts as a control, show that nanoscale particulate 

silver presents an equal or lesser hazard than ionic silver17,19,20,21,22,23,25,39,40. Other 

articles contradict the assumption that smaller particles of silver present a greater 

hazard than larger particles24 or that small silver particles are more likely to 

bioaccummulate than ionic or larger particles28,30. 

Even more compelling are the results of a recent Danish study15 comparing silver 

nanoparticles and silver acetate at 9 mg silver/kg/day, far above EPA argyria-protective 

levels. To quote from the abstract, “For the Ag-NP groups, no toxicological effects were 

recorded. For Ag-acetate, lower body weight gain..., increased plasma alkaline 

phosphatase..., decreased plasma urea...and lower absolute...and relative...thymus 

weight were recorded. In conclusion, these findings indicate toxicity of 9 mg/kg bw/day 

ionic silver but not of an equimolar Ag-NP dose.” While the nanoparticle results are 

interesting enough, those for silver acetate are particularly striking for the similarity to 

the findings for the silver zirconium phosphate product in dogs as summarized 

previously. This provides strong support for our view that the chemical, antimicrobial, 

and toxicological effects of silver antimicrobials, including small particle size silver, are 

to be attributed to silver ions. 

Furthermore, two new oral toxicity studies in rats, comparing silver ions and silver 

nanoparticles, have found that silver ion is the bioavailable species, leading to very 

similar organ distribution.31,41 Both studies found that silver ion is much more likely to 

bioaccumulate compared to silver nanoparticles. These new data, taken as a whole, 

provide ample evidence that there is no substantial difference in the toxicity profile of 

small silver particles and other silver compounds as they all share a common active 

moiety – the silver ion. 

Conclusion 

The STFNA and its members are committed to working with the Agency to facilitate 

efficient and effective collection of necessary new data to support the Registration 

Review process. To begin that process, the STFNA has carefully reviewed the wide 

variety of silver compounds covered by the Registration Review and have taken into 

account the “special cases” EPA has previously identified. We believe that the most 

scientifically supportable and process-efficient path forward is to consolidate review of 

all silver pesticide products. Accordingly, the Agency should issue a single DCI for all 

silver compounds using silver ion as the common test substance regardless of particle 

size, additional active, and presence of zeolite. Although there are several forms of 

silver-containing active ingredients under review, realization that the silver ion is the 

biologically active moiety for all silver antimicrobial products should facilitate bridging 

where scientifically justified, increasing efficiency for both the Agency and industry. 

Alternatively, the Agency must, at a minimum, take administrative steps to put all 

products on a common schedule. A staged schedule prevents the industry from 

collaboration for data generation. This will lead to repetitive data submissions that will

not add information value to the Agency‟s knowledgebase about silver hazards and 

risks. However, this would not preclude the EPA from adding product-specific data 

requirements for classes of products with unique use patterns or exposure profiles. 

Nor would the issuance of a single DCI prevent modifications to labeling or dose limits 

for specific products or use patterns if such changes are scientifically justified. We 

appreciate EPA‟s consideration and welcome our continued collaborative efforts to

maximize the results and conserve our resources.
