Dissolution and staining test

The Detergent compositions and speckle compositions were used on resolution and textile dyeing tested.

The resolution was through a conductivity method measured.

The discolour was measured using hand dishwashing methodology. The textiles used were knotted cotton and polyester (67%) / cotton (33%).

Three different hand wash procedures were used.

• (i) The powder was dissolved in water in a bowl and the textiles were then added
• (ii) the fabrics were placed in the water in the bowl and the powder was then added
• (iii) the fabrics were moistened thoroughly and a concentrated paste (powder and a little water) applied directly.

In Methods (i) and (ii) were the detergent compositions with a concentration in the wash liquor of 3.5 g / l used.
