General. The final issued standard was developed in an open and transparent process with stakeholder input that included producers, users, and general interests.
The requirements in the standard are based on an assessment of the environmental, health, or social impacts associated with the products, services, or organizations covered in the scope of the standard. These requirements are subject to revision, and generally cover aspects above and beyond regulatory compliance. This standard neither modifies nor supersedes laws and regulations. Any conformity assessment to this standard requires compliance with all applicable laws and regulations for the manufacturing and marketing of the products.
Provisions for safety have not been included in this standard, since they are supervised by regulatory agencies. Adequate safeguards for personnel and property should be employed for all stages of production, and for all tests that involve safety considerations.
Products, services, or organizations that are substantially similar to those covered by this standard in terms of function and life cycle considerations may be evaluated against the intent of the requirements of this standard, accounting for relevant differences between the intended scope of the Standard and the actual product, service, or organization to be evaluated.
This standard may not anticipate a feature of the product that may significantly, and undesirably, increase its impact on the environment, health, or society. In such a situation, Green Seal will ordinarily amend a standard to account for the unanticipated environmental, health, or societal impacts.
Normative references (e.g., other standards) in this standard intend to refer to the most recent edition of the normative reference. Test methods may be required for product evaluation. Unless explicitly stated that a specified method is the only acceptable one, the intent of the standard is that an equivalent test method may be accepted at Green Seal’s sole discretion.
Certification to this standard shall be awarded only by Green Seal, or, with Green Seal’s explicit written permission, by a third-party certification program conducting on-site audits.
Disclaimer of Liability. Green Seal, as the developer of this standard, shall not incur any obligations or liability for any loss or damages, including, without limitation, indirect, consequential, special, or incidental damages, arising out of or in connection with the interpretation or adoption of, reliance upon, or any other use of this Standard by any party. Green Seal makes no express or implied warranty of merchantability or fitness for a particular purpose, nor any other express or implied warranty with respect to this Standard.

2.0 SAFER CHEMICALS
2.1 Safer Ingredients
2.1.1 Aquatic Biodegradability. Each of the organic ingredients in the product as used shall exhibit ready biodegradability in accordance with the OECD definition, except for polymers.
Biodegradability shall be measured according to any of the following methods:
- OECD Methods 301A–F
- OECD 310
- ISO 7827, 9439, 10707, 10708, or 14593.
Specifically, within a 28-day test, the organic ingredient shall meet one of the following criteria within 10 days of the time when biodegradation first reaches 10%:
- Removal of Dissolved Organic Carbon (DOC) > 70%
- Biochemical Oxygen Demand (BOD) > 60%
- BOD, as % of Theoretical Oxygen Demand (ThOD) > 60%
- CO2 evolution, as % of theoretical CO2 > 60%
Per OECD guidance the 10-day window requirement does not apply to structurally related surfactant homologues.
Alternative Evaluation Options: Substances that Do Not Exhibit Ready Biodegradability.
For organic ingredients in the product as used that do not exhibit ready biodegradability, one of the following options may be acceptable:
- The manufacturer may demonstrate biodegradability in sewage treatment plants using the Coupled Units Test found in OECD 303A by demonstrating DOC removal > 90%.
- The manufacturer may demonstrate that the compound has low aquatic toxicity (acute LC50 ≥ 100 mg/L for algae, daphnia, or fish) and exhibits inherent ultimate biodegradability with biodegradation rates above 70% (measured as BOD, DOC, or COD), per ISO test methods 9887 or 9888 or OECD 302A-C.
Note: Testing is not required for any ingredient for which sufficient information exists concerning its biodegradability, either in peer-reviewed literature or databases. In the absence of experimental data, Quantitative Structure-Activity Relationship data from EPA’s BioWin (EpiSuite) models may be considered.
2.1.2 Aquatic Toxicity. The product as used shall not be toxic to aquatic life. A compound is considered not toxic to aquatic life if it meets one or more of the following criteria: Acute LC50 for algae, daphnia, or fish >100 mg/L. Aquatic toxicity tests shall follow the appropriate protocols in ISO 7346.2 for fish or OECD test guidance 203 for fish, OECD test guidance 201 for algae, and OECD test guidance 202 for daphnia.
For purposes of demonstrating compliance with this requirement, aquatic toxicity testing is not required if sufficient aquatic toxicity data exist for each of the product’s ingredients to demonstrate that the product mixture complies.
2.1.3 Combustibility. The undiluted product shall not be combustible. The product or 99% by volume of the product ingredients shall have a flashpoint above 150 °F, as tested using either the Cleveland Open Cup Tester (ASTM D92) or a closed-cup method ISO 13736 or ISO 2719. Alternatively, the product shall not sustain a flame when tested using ASTM D4206.
2.1.4 Fragrances. Manufacturers shall disclose the use of any added fragrances on their safety data sheets (SDSs) and product labels. Any ingredient added to a product as a fragrance must follow the Code of Practice of the International Fragrance Association.

2.1.8 Products Containing Microorganisms. Products that contain microorganisms shall meet all Annex D criteria.
2.1.9 Prohibition of Carcinogens, Mutagens, and Reproductive Toxins. The undiluted product shall not contain any ingredients that are carcinogens, mutagens or reproductive toxins. For the purposes of this standard, naturally occurring elements and chlorinated organics, which may be present as a result of chlorination of the water supply, are not considered ingredients if the concentrations are below the applicable maximum contaminant levels in the National Primary Drinking Water Standards found in 40 CFR Part 141.
Note: Refer to Annex C for the exemption of titanium dioxide in products that contain enzymes.
2.1.10 Skin and Eye Damage. The undiluted product shall not cause skin corrosion or cause serious eye damage. For purposes of demonstrating compliance with this requirement, data may be evaluated for each of the ingredients in the undiluted product. If the ingredients at their concentrations in the undiluted product are not shown to cause skin corrosion or serious eye damage, then the product will not be considered to cause skin corrosion or serious eye damage. Results from peer-reviewed studies or standard in vitro or in vivo test methods may also be accepted. Testing is not required for any ingredient for which sufficient information exists.
Further, a product is considered to cause skin corrosion or to cause serious eye damage if it has a pH less than or equal to 2.0 or greater than or equal to 11.5, unless data prove otherwise.
Note: Refer to Annex B for potential alternate thresholds for products as powders/solids/non-aqueous liquids.
2.1.11 Skin Sensitization. The undiluted product shall not be a skin sensitizer. For purposes of demonstrating compliance with this requirement, data may be evaluated for each of the product’s ingredients. If the ingredients at the concentrations in the undiluted product are not shown to be skin sensitizers, then the product will not be considered to be a skin sensitizer.
2.2 Safer Products
2.2.1 Acute Toxicity. The undiluted product shall not be toxic to humans. A product is considered toxic if either of the following apply:
Oral lethal dose 50 (LD50) < 5,000 mg/kg
Inhalation lethal concentration (LC50) < 20 mg/L at 1 hr
For purposes of demonstrating compliance with this requirement, existing acute toxicity data for each of the product’s ingredients in the undiluted product may be used. These data are used to calculate a weighted average that assumes that the toxicity of the individual ingredients is additive. The toxicity values are adjusted by the weight of the ingredients in the product and summed using the following formula:
Where,
TP = toxicity of the product
wti = the weight fraction of the ingredient
TVi = the toxicity value for each ingredient (LD50)
n = number of ingredients
Inhalation toxicity shall be determined from all ingredients with a vapor pressure greater than 1 mm Hg at ambient conditions (1 atm pressure and 20-25° C).
Note: Refer to Annex B for potential alternative thresholds for products as powders/solids/non-aqueous liquids.
2.2.2 Eutrophic Agents. The product as used shall not contain more than 0.5% by weight of total phosphorus.
2.2.3 Volatile Organic Compound (VOC) Content. VOCs include all organic compounds that have a vapor pressure of greater than 0.1 mm mercury at 1 atm pressure and 20º C. “VOC content” means the total weight of VOCs in a product expressed as a percentage of the product weight.
The VOC content of the product as used shall not exceed the current regulatory limits of the Air Resources Board for the State of California (CARB) for its product category.
The VOC content shall be determined in one of the following ways:
- By summing the percent by weight contribution from all volatile organic ingredients.
- According to the California Air Resources Board Method 310 (or equivalent), modified to include all fragrances and all volatile organic ingredients3Evaluation of the VOC content in this standard includes all fragrances and volatile organic compounds present in the product at 0.01% or more. Evaluation of the VOC content under Method 310 exempts fragrances and all volatile organic compounds present below 0.1%..
Current CARB regulatory limits for VOCs4These limits are a reference to the current CARB regulatory limits and will be updated to reflect any amendments made by CARB in the future..

- A statement that immune-compromised individuals or those with asthma should avoid exposure to products containing enzymes from both direct use and incidental contact during or shortly after application of these products and instruction, when necessary or appropriate, for follow-up treatment
F. Industrial Hygiene. Documentation shall be provided to the certification organization that demonstrates that the manufacturer has implemented an industrial hygiene plan intended to minimize concentrations of and exposure to airborne enzymes (e.g., engineering controls, work practices, and personal protective equipment) and monitor the air concentrations of the enzyme/s and worker illness/sensitization due to the enzyme/s. An example of best practices that may be applicable for this plan is available at AISE.
ANNEX D – MICROORGANISMS (Normative)
Products Containing Microorganisms. Products that contain microorganisms shall meet all of the following with any specified testing conducted with an objective, scientifically validated method under controlled and reproducible laboratory conditions (and appropriate testing details provided to the certification program):
A. Genetically Modified Microorganisms in Microbial Products. The presence of GMM as a deliberate addition or as a contaminant above 0.01% in the finished product is prohibited.
B. Microorganism Biosafety. All microorganisms shall be classified as WHO Risk Group 1 or equivalent biosafety designation. For strains that do not appear on any international biosafety designation lists, alternative means may be acceptable; consultation with the certifying organization may be required.
C. Microorganism Strain Identification. Microorganism strains shall be identified through a taxonomic review (e.g., genetic or phenotypic analysis) that is provided by a full-service culture collection listed with the World Federation of Culture Collections, whether or not the strain is part of the collection.
D. Absence of Contaminants. Pathogenic microorganisms shall not be present in the microbial strain, finished product, or at the end of the product’s intended shelf life. Testing for the presence of pathogenic microorganisms shall be conducted according to the Joint Food and Agriculture Organization of the United Nations/WHO Expert Committee on Food Additives (JECFA) Combined Compendium of Food Additive Specifications standard microbiological analytical methods or comparable method and a Certificate of Analysis shall be provided to the certification program.
E. Effective Prevention Measures and Treatment. All microorganisms shall be demonstrated to be susceptible to the following prevention and treatment measures:
- An antimicrobial agent, as demonstrated by testing the microbial strain in the product against an acceptable substance (i.e., an EPA general disinfectant, Center for Disease Control low-level disinfectant, or a registered antimicrobial agent by Health Canada). The test method should be modeled on the EPA/Office of Pesticide Programs Standard Operating Procedure (SOP) or the AOAC International Use Dilution Method for Testing Disinfectants, SOP Number: MB-05-04, but replace the pathogenic strains specified in these SOPs with the microbial strain(s) in the product.
- One of the five major antibiotic classes (aminoglycoside, macrolide, beta-lactam, tetracycline and fluoroquinolones), as demonstrated by testing the microbial strain in accordance with the Kirby-Bauer disk method.
F. Microbial Count. A microorganism used to serve the primary cleaning function in the undiluted product shall have a plate count that is greater than or equal to 1×107 CFU per milliliter for liquid products and 1×109 CFU per gram for solid products. A total plate count shall be conducted in accordance with the methods for microbiological analyses listed in the JECFA Combined Compendium of Food Additive Specifications or comparable method. An exception shall be made for microorganisms used to serve a secondary function in the undiluted product.
G. Product Label and User Information. The product label shall disclose that the product contains microorganisms. An alternative phrase for microorganisms may be approved by the certification program, e.g., “bacterial cultures.” The product label shall include a statement that the product will not function effectively when used in conjunction with disinfectants, such as chlorine bleach. For products that are sold for use in spray packaging,8Or designed for use in spray packaging the product label shall include a statement that the product should not be sprayed into the air.
H. Additional Requirements for Products in Spray Packaging. Products that are sold in spray packaging9Or designed for use in spray packaging shall not be formulated with any fungal or mold species. Yeast species are acceptable. Additionally, at least one of the following requirements shall be met:
The product shall undergo inhalation exposure testing. The total airborne concentration of microorganisms shall not be above 10,000 CFU/m3. Testing parameters shall be in alignment with the A.I.S.E. Spray Protocol (2020).10Spray Protocol,” https://www.aise.eu/our-activities/standards-and-industry-guidelines/safe-handling-of-enzymes.aspx
Microbial species in the product shall only be those that are listed on the European Food Safety Authority’s (EFSA) Qualified Presumption of Safety (QPS) List.
