A fluid washing composition is disclosed, which is including four separate components housed in respective independent tanks of a laundry washing machine equipped with a programme for the selection, dosing and differentiated delivery of said separated components according to the varying characteristics of the individual laundry batch. The fluid washing composition is arranged so that said separate components have the following formulation:
Component 1 - detergent formulation with a pH ranging 10 between 4.0 and 12.0, with high detergent effect in washing programmes at temperatures in the range 40°-60°C, having a specific action on cotton fibres and, in particular, on white-coloured items;
Component 2 - detergent formulation with a pH ranging between 8.0 and 12.0, with high detergent effect in washing programmes at temperatures in the range 15°-40°C, having a specific action on synthetic, coloured and animal-origin fibres;
Component 3 - enzyme-based stain-removing formulation based at least on protease and lipase and possibly amylase with a pH ranging between 4.0 and 6.0 and preferably between 5.0 and 5.5, stabilised with polyols and calcium chloride;
Component 4 - after-wash conditioning formulation, with a pH ranging between 2.0 and 4.0,
whereby distributing said components across four different and independent volumes, separating the components enzymes and surfactants.
