Abstract
Compact liquid or gel-form laundry detergent compositions processes for manufacturing such compositions, wherein the compositions comprise at least a stabilization system against phase splitting having an alkanolamine and a coupling polymer component and preferably a stabilization system against phase splitting having an alkanolamine, a coupling polymer and a crystalline structurant component.
Claims13
A process for manufacturing a concentrated aqueous liquid or gel-form laundry detergent comprising the steps of:
- (i) providing a crystalline structurant premix, wherein said premix comprises from about 2% to about 10%, by weight of said premix, of a crystalline structurant,
- from about 2% to about 10%, by weight of said premix, of an alkanolamine, and
- from about 5% to about 50%, by weight of said premix, of an anionic nonsoap surfactant and,
- a liquid carrier, wherein said premix is substantially free from monovalent and/or divalent inorganic metal ions,
- wherein the making of said premix comprises emulsifying and then crystallizing said structurant;
- (ii) adding said premix to a laundry detergent composition,
- comprising a coupling polymer at a level of from 0.1% to 5% by weight of the laundry detergent,
- at least 10% by weight of the laundry detergent composition of anionic nonsoap surfactant,
- at least 0.1% of other surfactants such that the total surfactant level is at least 20% by weight of said detergent composition,
- no more than 15% by weight of said detergent composition of an organic non-amino functional solvent,
- and a laundry adjunct selected from the group consisting of detergent active enzymes, textile optical brighteners, fabric hueing dyes, and mixtures thereof,
- wherein said premix is added to said laundry detergent composition in an amount sufficient to provide from 0.05% to 2%, by weight of said detergent, of said crystalline structurant, and wherein said crystalline structurant comprises hydrogenated castor oil.
