<p>Detergent powder manufacturing process in which solid alkali particulate material is blended and reacted with liquid anionic acid surfactant precursor in a mixer to form anionic surfactant and the solid particulate alkali is also blended with nonionic surfactant added in a liquid form to the same mixer, characterised in that the nonionic surfactant is added in admixture with anionic surfactant which has been neutralised using a liquid alkaline solution. In addition, the powder produced according to the process and tablets made by compressing the powder, optionally in admixture with other detergent ingredients. In addition, use of the tablets so formed in the laundering of fabrics.</p> |
