Description
- The present invention is in the field of hard surface cleaning compositions, in particular liquid detergent compositions with improved emulsification and oily soil removal of hard surfaces, such as tableware.
- Household cleaning activities involve the use of a detergent product and water to rinse off the detergent product and finish the cleaning process. These activities are typically performed daily, often more than once a day, such as dish washing. That is, hard surface cleaning, dishwashing and other household cleaning activities are time consuming activities and, ideally, can be optimized when using products with excellent detergency and soil removal capacity.
- Consumers normally associate cleaning efficiency with foam formation during the main wash step. Cleaning products with excellent foaming capacity are therefore of high commercial relevance. Although it is known that, technically, high foaming is not directed to soil removal capacity, a product with reduced foamability during the main wash is not appreciated by consumers, even if it has better detergents and improved soil removal capacity. It is thus desired to have a product that has both excellent emulsification and soil removal capacity, as well as good foamability in the main wash.
-
WO 2016/030226 relates to a liquid detergent composition having reduced foaming formation during rinse while maintaining foaming characteristics in the main wash. The examples describe compositions comprising: a surfactant system comprising sodium lauryl ether sulphate having 1 to 2 ethylene oxide units per molecule and linear alkyl benzene sulphonate, a non-ionic surfactant, fatty acids and water. -
WO 2017/140472 describes dishwash compositions which form a foam during cleaning that is easily rinsed off. The compositions comprise an antifoaming system, the composition comprising a combination of fatty acids and non-ionic surfactants. - There remains a need for a hard surface cleaning composition with excellent oily soil removal without compromising consumer satisfaction in terms of foam formation in the main wash.
- The inventors have developed a liquid detergent composition with improved foam formation during the main wash step ('flash foaming'). Advantageously, it has been observed that the compositions according to the invention have excellent emulsification and oily soil removal capacity. Unexpectedly, it has been found that a combination of fatty acid with polyethylene oxide of high molecular weight increases the emulsification capacity of a liquid detergent composition.

Details are shown in Tables 2 and 3. All the formulations were subjected to emulsification tests.
- Different amounts of fatty acids ('FA') and polyethylene oxides ('Polyox') (in weight % based on total composition) were added to base compositions above.
- The compositions were evaluated as to their emulsification capacity. 8.08 g of the compositions were poured into a 250 ml beaker, to which 50 ml of 10 F.H. ('French hardness') water at 25°C were added followed by stirring until dissolution. To the homogeneous mixture, 44.56 g of coloured sunflower oil (1.0 l of oil coloured with 0.045 g of Red dye) were added. The mixture was stirred for 2 min at 1200 RPM, and transferred to a 250 ml glass cylinder.
-
- The results of 'E value' are in table 2 below.
