Definitions
- the invention relates to liquid dishwashing detergent compositions.
- the compositions have antibacterial properties.
- Liquid dishwashing compositions are much desired by consumers and can be used neat or diluted.
- a composition In diluted mode, a composition is diluted in water to form a wash liquor in which the dishes to be cleaned are immersed.
- neat mode a composition is directly applied neat onto dishes, and in this mode a dish implement is often use. Specifically, the composition is applied onto the implement, usually a sponge or a dishcloth, which is in turn contacted with the dishes to be cleaned.
- dish implements are left humid most of the time, and so they provide a good medium for bacterial growth.
- the contaminated implement which is used to clean dishes will in turn contaminate those dishes.
- compositions of the present invention are liquid dishwashing compositions comprising :
- hydrotrope selected from the group consisting of salts of cumene sulfonate, toluene sulfonate, xylene sulfonate, benzene sulfonate or mixtures thereof;
- the invention further encompasses a method of washing dishes with these compositions.
- the anti bacterial efficacy of said formulations is mainly driven by a synergy between the hydrotrope(s) and the unsaturated aliphatic terpene alcohol(s) or derivative.
- compositions of the invention are aqueous liquid compositions. They typically comprise from 30% to 90% by weight of the total composition of water, preferably 40% to 85%.
- compositions herein are liquid and so they typically have a viscosity of from 5 cps to 2000 cps, preferably 5 cps to 400 cps, most preferably 5 cps to 350 cops, measured with a Brookfield Viscometer, with a No. 18 spindle, at 20°C.

- alkyl alkoxylated sulfates of the formula R-
- alkyl alkoxylated sulfates with lower values for n, on an equal weight basis, typically when n is below 1.0, improves the performance of the composition on grease removal and sudsing due to the corresponding increase in moles of anionic but results in an increase in the total amount of unalkoxylated alkyl sulphate, and this seems to make the low temperature instability issue more acute. If different alkyl alkoxylated sulfates are used which have different n values, the resulting average n value of the alkyl alkoxylated sulfate in the composition will be the weighted molar average n value of the individual n values of the different alkyl alkoxylated sulfates used in the composition.
- the average n value is less than 0.5, the stimulus to skin increases and this is not desirable. On the other hand, if the average n value is more than 3, the detergency deteriorates.
