Abstract
The present invention relates to a process for reducing viscosity and improving draining characteristics of a structured lamellar composition by maintaining specific order of addition. More specifically, by adding to a composition a premix comprising F-dye and surfactant before addition of remaining surfactant, the advantages mentioned above are obtained.
Claims5
A process for reducing the viscosity and improving draining characteristics of a structured lamellar composition comprising
- (a) a main mix comprising about 5-20% water, about 5-40% builder, 0-20% enzyme stabilizer, about 2-10% alkali metal hydroxide and about 2-10% buffer system comprising monoethanolamine and triethanolamine, all percentages being by weight of the final composition
- (b) at least a nonionic surfactant and one or more surfactants selected from the group consisting of an ionic surfactants, cationic surfactants, zwitterionic surfactants, and amphoteric surfactants;
- and
- (c) a fluorescent dye;
- which process comprises adding to a main mix a 1-20% by weight of a premix comprising the fluorescent dye and 20-70% by weight of the total nonionic surfactant in the final composition before addition of the remaining surfactant (b) to said main mix;
- said premix comprising, in addition to fluorescent dye, about 0-70% by weight water and about 30-100% by weight nonionic surfactants.
