Definitions
- the present invention relates to a cleaning composition having a foam boosting silicone. More particularly, it relates to a fabric cleaning composition having lower concentration of detersive surfactant in combination with the foam boosting silicone.
- Cleaning compositions comprising detergent surfactants are well-known in many fields of application, for instance in laundry washing and fabric treatment compositions. Most compositions having surfactant have a tendency to foam, in particular once they are diluted upon application. In many such applications, especially where consumers prepare suds or lather from the cleaning composition themselves, such foaming is perceived as a sign of detergency. In consumer minds, often foaming power is even perceived as a prerequisite for detergency. Therefore, good foam formation is a desirable characteristic for many cleaning compositions. It is especially desirable that the foamy or frothy layer, once formed, does not disappear readily but remains in place for the consumer to be observed.
- Hand-wash cleaning compositions suitable for washing fabrics are known. Such compositions should have proper foaming performance and must also be able to deliver excellent stain and soil removal benefits.
- the user may also use the suds profile and the appearance of the foam like the foam density, and foam whiteness as an indicator that the wash solution still contains active detergent ingredient and the user usually doses the cleaning detergent composition depending on the suds remaining and renews the wash solution when the suds/ foam subsides or when the foam does not look thick enough.
- a cleaning composition particularly a manual hand-wash cleaning composition that provides little or low-density foam, or short-lived foam would tend to be replaced by the user more frequently than is necessary.
- formulating a cleaning composition to provide optimal foaming may negatively affect other characteristics.
- a well-known way to enhance foaming is by increasing the amount of surfactant present in a formulation.
- Most laundry cleaning formulations include a higher level of surfactant than necessary for removal of the soil so as to obtain desired foaming. From a sustainability point of view, this is undesirable and creates a need to provide an alternative way of enhancing the stability of the foam formed from cleaning compositions.
- a cleaning composition it is desirable for a cleaning composition to provide a good foam volume and density as well as good foam stability during the initial mixing of the composition with water and where the foam is also present during the entire washing operation.
- Compounds known as pro-foamers, foam boosters and foam regulators, have been included in certain detergent products where high foam volume is functionally or aesthetically desirable.
- composition comprising polyalkylene oxide siloxane co-surfactants with different amounts of polyoxyalkylene group are known in many fields of applications.

- US 2009/0075858 A1 discloses a hard surface treating composition having polyalkoxylate trisiloxane for providing good first-time and next-time cleaning performance on various stains.
- the enhanced foam stability is provided upon dilution of the fabric cleaning composition upon use.
- the fabric cleaning composition of the present invention provides stable foam and good cleansing while using lesser amounts of detersive surfactant.
- siloxane according to the present invention lowers the dynamic surface tension of wash liquor, a factor which is believed to improve the overall foam boosting ability of the composition and provides improved cleaning or detergency in composition with lowered total detersive surfactant content.
- fabric cleaning composition having lower levels of surfactant in presence of the siloxane according to the present invention gives the benefit of delivering the desired foam levels at the washing stage and a reduction of the foam in the rinse stage. This provides the benefit of lowering the consumption of surfactants and water without compromising on the benefits delivered to the consumer.

- the invention provides use of siloxane having polyoxyalkylene group represented by the general formula (I), (II) or mixtures thereof, according to the present invention to increase the foam stability of a cleaning composition, preferably a cleaning composition comprising 2wt% to 20wt% surfactant.
- the invention provides a method of laundering fabric comprising the steps of:
- Example 1 Evaluation of powder laundry detergent composition having the solid foam boosting system.
- a first solid foam boosting system having the composition as described in Table 1 was prepared and tested in a powder detergent composition suitable for laundry washing in handwash scenario.
- Table 1 Solid foam boosting system wt% Formula Siloxane with a polyoxyalkylene group 11
- Foam enhancing additive methyl ester of fatty acid
- C 18 fatty acid made from vegetable oils (commercially available as Agnique ME 18 RD-F from BASF).
- Sodium carbonate 85 100
- a second set of solid foam boosting system was prepared which had a formulation as provided in Table 1a.
- Table 1a Solid foam boosting system wt% Siloxane with a polyoxyalkylene group 15 Sodium carbonate 85 Total 100 4 different siloxanes with structures as provided below were used to prepare comparative and inventive solid foam boosting composition with the formulation as provided in Table 1a.
- the first and the second set of solid foam boosting system were used to prepare powder detergent composition having the formulation as given in Table 2 and were thereafter used for evaluating the foam performance.
- Control (C) A control formulation was prepared which included 19.4wt% detersive surfactant and no solid foam boosting system.
- Negative Control The second composition was a negative control (NC) and was prepared by reducing the detersive surfactant levels in the control formulation by approximately 30% and the formulation was made up to 100 using sodium sulphate. A negative control was placed in the study to contextually observe the decrease in foam height in absence of the solid foam boosting system having the siloxane in accordance with the present invention.
- This comparative composition was similar to the negative control in terms of inclusion of reduced levels of detersive surfactant as compared to the control however this composition included 1wt% of the solid foam boosting system (given in table 1a having the siloxane with structure Comp Ex A as given above).
- the seven detergent compositions namely the Control (C), Negative control (NC), comparative examples Ex A, Ex B and Ex C and the inventive examples Ex 1 and Ex 2, as given in Table 2 were evaluated for their foaming performance under two different conditions.
- Foam height measurement The height of the foam formed during the hand washing process at the pre-wash stage, post wash stage and the post-rinse stage in the bucket having the foam and the wash liquor/rinse liquor is measured by recording the height of the foam formed calculated from the wash liquor level to the upper point till where the foam is observed. This reading was repeated at 4 different points around the diameter of the bucket and the average of these reading were noted as the foam height.
- the wrung fabrics were rinsed in clean water. Rinsing was conducted in 3 stages namely rinse 1, rinse 2 and rinse 3. For each rinse, 10 litres of fresh water having 20° fH (Ca:Mg 3:1) hard water was taken and the fabrics were rinsed and the foam height in each rinse bucket was measured and recorded as post-rinse foam height.
- the data provided in Table 3 shows that a lowering of the surfactant level by approximately 30% in the negative control as compared to the control formulation has a direct impact on the foam height of the detergent solution in the pre-wash and the post wash stage in a clean system.
- the composition (Ex 1, Ex 2) according to the present invention having reduced surfactant level and the solid foam boosting system has comparable foam height as that of the control composition in both the pre-wash and the post wash stage.
- the foam behaviour is similar to that of the control composition which is desirable as the consumer prefers adequate foaming in the pre-wash and wash stages but during the rinsing stage a lower foaming is desired as this saves water and effort required for rinsing the fabrics.
- comparative siloxane of Ex A having lesser number of polyoxyalkylene group (10 oxyethylene group) does not show any benefit on improving foam height in the pre-wash stage and performs similar to negative control.
- comparative siloxane of Ex B having lesser number of polyoxyalkylene group (10 oxyethylene group and 1 oxypropylene group) and comparative siloxane of Ex C (62 D units) having p value greater than 50 units decreases the foam height in the pre-wash stage.
- Foaming performance in soiled system for hand washing process :
- the protocol used for the evaluation of the 7 detergents in soiled system by handwashing involved the following process. 7 different buckets were taken and 12 litres of clean water having 20° fH (Ca:Mg 3:1) hard water was added into each of these buckets. To this water, 42 grams of the control detergent composition was added to obtain the detergent solution. Similarly, 42 grams of the negative control and the Ex 1, Ex A, Ex B, Ex C and Ex 2 detergent compositions were added to the other 6 buckets to obtain respective detergent solution. Each detergent solution was then whisked for 20 seconds to allow the foam to form. At the end of 20 seconds, the foam height was measured and recorded as pre-wash foam height.
- Preparation of soiled water 2 SBL 2004 soil strips were taken and added into 1 litre of water and heated to 90°C for 30 minutes to leach out the soil in water to provide the soiled water.
- the wrung fabrics were rinsed in clean water. Rinsing was conducted in 3 stages namely rinse 1, rinse 2 and rinse 3. For each rinse, 10 litres of fresh water each having 20° fH (Ca:Mg 3:1) hard water was taken and the fabrics were rinsed and the foam height in each rinse bucket was measured and recorded as post-rinse foam height.
- the data provided in Table 4 shows that a lowering of the surfactant level by approximately 30% in the negative control as compared to the control formulation has a direct impact on the foam height of the detergent solution in the pre-wash and the post wash stage in presence of soil.
- the comparative siloxane of Ex A, Ex B and Ex C all show lower foam height in the pre-wash stage indicating that no improvement is shown by addition of these siloxanes to the composition.
- the addition of the comparative siloxane (Ex A, Ex B and Ex C) has a negative effect on the foam height as the foam height is lower than the foam height in the negative control.
- the composition (Ex 1, Ex 2) according to the present invention having reduced surfactant level and the solid foam boosting system has comparable foam height in both the pre-wash and the post wash stage as that of the control composition with higher levels of surfactant.
- the foam behaviour of the rinse solution having the composition of Ex 1 shows lower foam amount than that of the control composition which is more desirable to the consumer.
- the consumer prefers adequate foaming in the pre-wash and wash stages but during the rinsing stage a lower foaming is desired as this saves water and effort required for rinsing the fabrics.
