What is the Green Seal Certification Mark?
Green Seal is a non-profit organisation whose mission is to use science-based programmes to empower consumers, purchasers and companies to create a more sustainable world. Green Seal sets leadership standards that aim to reduce, to the extent technologically and economically feasible, the environmental, health, and social impacts throughout the life-cycle of products, services, and companies.

What are the Green Seal Test Requirements?
The Standard Performance requirements (The Green Seal Standard for Cleaning Products for Household Use page 6) are:
- Each product as used, when diluted with water from the cold tap at no more than 500F, shall clean common soils and surfaces in its category effectively, as measured by a standard test method.
- General purpose cleaners shall remove at least 80% of the particulate soil in the American Society for Testing and Materials (ASTM) D4488-95-A5.
ASTM D4488-A5 is a standard method for testing cleaning performance of products intended to be used on resilient flooring and washable surfaces and walls. It is recognised worldwide. This standard applies to all multi-purpose household cleaners and also some industrial/institutional cleaners.
How is the Green Seal Test Performed?
A specific soil/substrate combination was used with white vinyl tiles. The soil had two component parts: a particulate soil and an oil blend soil:
- The particulate soil portion consisted of 10 ingredients, which were mixed by hand and transferred to a ball mill to be mixed for 18 hours. The mixture was dried and pulverized and then filtered through a mesh screen.
- The oil blend soil consisted of 9 ingredients prepared over a steam bath.
A template frame was used to contain precisely 50mg of particulate soil in the middle area of the tile. A paper towel cut to the exact size was wet with 5 drops of the oil blend soil and placed over the particulate soil for 10 seconds. The operator took care to ensure consistent application of the soil to the vinyl; too much pressure whilst applying the soil to the tile may alter the test results.
The tiles were air-dried for 24 hours before the cleaning test was performed using washability apparatus.
How Efficacy is Evaluated for Sustainable Cleaning Products
Reflectance readings were taken of the vinyl tiles before soil application, after soil application and after cleaning, using a colorimeter. These values determine the overall cleaning efficiency of a product intended for use on resilient flooring, surfaces and washable walls. Note: this test excludes ‘windows, mirrors, carpets, ceramic tiles, and laminated counter tops.’
What Were the Results?
ASTM D4488-A5 gave a result of 83.09% with our Provilan probiotic sustainable cleaning products, showing they meet the Green Seal expectations.
