The North American Unilever Small and Mighty products would be slightly different given that they're formulated for top loading machines with much higher water volumes that can handle foam.
Their European counter Small and Mighty liquids are all low foaming and designed for low water volume machines.
Their recent predecessor, Persil Liquigel was a terrible product. It completely over-foamed at all times. It might have been a good product for a US toploader.
Using the suggested dose, according to the instructions on the bottle in a Whirlpool front loader foam actually flowed onto the floor during the spin after the wash!!
Thankfully, the Small and Might formulation actually works!
I really like the smell of Persil Small and Mighty, it's kind of citrus, but not quite. Hard to describe. Extremely fresh though.
Surf Small and Mighty Sun Fresh is a very 'traditional' laundry detergent smell. Kind of takes me back to the 1980s. Nice smell though!
