Definitions
- the present invention is related to non-aqueous liquid detergent compositions.
- Detergent compositions have traditionally contained a number of non-active ingredients. This has resulted in the increase in volume of the compositions and thus the packaging therefore. It is now considered highly desirable to reduce the volume of detergent compositions due to environmental considerations and produce more compact detergent formulations. One means to achieve this is to reduce the amount of non active ingredients such as water in detergent compositions. Reducing and preferably removing non active ingredients, particularly water results in a more compact composition. This in turn results in the need for less packaging material and smaller more manageable containers.
- non-aqueous detergent compositions which exhibit at least the same cleaning performance of an equivalent aqueous detergent composition.
- surfactants comprising 2 vicinal hydroxyl groups selected from poly hydroxy fatty acid amides, alkyl mono or di(alkoxy) glyceryl ethers, alkane 1,2-diols, alkyl glycerates and N-alkyl-lactobionamides. This is because such surfactants are especially effective with respect to their greasy stain removal performance.
- these surfactants comprising 2 vicinal hydroxyl groups can indeed be solubilized in non-aqueous detergent compositions. This is achieved by the addition of a boron comprising compound such as boric acid.
- the boron comprising compound interacts with the hydroxyl groups of the surfactant to form complexes. These complexes disrupt the crystallinity of the surfactant and thereby prevent its precipitation.
- Another advantage of the present invention is that certain ingredients such as dye transfer inhibition systems which are not compatible with an aqueous environment can be incorporated into non-aqueous liquid detergent compositions. This contributes to overall cleaning performance of liquid detergent compositions.
