Weber & Leucht came up with a formula to rate the phenomenon of microplastic shedding called the MLC Index, which is basically the amount of microparticle loss per cleaning cycle of one square metre of cleaning textile.
The lab simulated 100 washing cycles using an accelerated cleaning machine that washes, rinses, extracts shed material and dries in 30 minutes. Then Weber & Leucht applied three different analytical processes on the products.
- An REM-EDX analysis that identified and measured fibres and microplastics before and after washing
- An FT-IR (ATR method) test that identified and measured organic deposits, polymers and microplastics
- A thermal analysis that identified and measured polymers and analysed material stability
As we expected, the Vikan products did well under the extensive testing. Our marks on the MLC Index were as follows:
- A+ – Original microfiber cloth (zero emission)
- A+ – Lustre microfiber cloth (zero emission)
- A – DampDry 31 mop (low emission)
- A – Damp 42 mop (low emission)
- A – Damp 47 mop (low emission)
- B – Damp 43 mop (medium emission)
The ‘A+’ marks mean that these Vikan products score equal to or better than 96% of all products tested, while our ‘A’ marks indicate performance in the 88th percentile. Even a ‘B’ mark means the product is in the top 25% of the products tested.
