A liquid fabric care composition that includes such a structuring premix. A process for making a structured liquid fabric care composition.
Claims17
A structuring premix comprising:
- a) about 1.0% to about 16% by weight of a non-polymeric, crystalline, hydroxyl-containing structuring agent comprising crystallizable glyceride;
- b) about 4.0% to about 20% of at least two nonionic surfactants, wherein the at least two nonionic surfactants comprise:
- (i) at least one low HLB nonionic surfactant, wherein the at least one low HLB nonionic surfactant has an HLB of about 5.0 to about 9.5, and wherein the structuring premix comprises about 0.5% to about 8.0% by weight of the low HLB nonionic surfactant;
- (ii) at least one high HLB nonionic surfactant, wherein the at least one high HLB nonionic surfactant has an HLB of about 10.5 to about 16.0, and wherein the structuring premix comprises about 1.5% to about 16% by weight of the high HLB nonionic surfactant;
- wherein the average HLB of the at least two nonionic surfactants is about 11 to about 12.5, and the nonionic surfactants for both the low HLB nonionic surfactant and high HLB nonionic surfactant are selected from alkoxylated alcohol nonionic surfactants, alkyl polyglucoside nonionic surfactants, and mixtures thereof,
- wherein the average HLB is the weight average of the HLBs of the individual surfactants;
- and
- c) from 45% to 97% by weight of the premix of water, wherein the premix comprises no additional surfactant beyond the nonionic surfactant and anionic surfactant, and the premix comprises less than 5% by weight of the anionic surfactant.
