Definitions
- the present invention relates to a laundry cleaning composition; in particular, a solid laundry detergent composition having a desirable foam profile during the laundering process.
- Synthetic detergents are widely used for laundering fabrics, due to their efficiency in cleaning and stain removal.
- formulated laundry detergent composition includes various additives to provide improved cleaning and sensorial benefits. Proper foam level is a sensorial benefit which most consumers desire during the laundering process.
- Foaming or sudsing is an important factor to consider when formulating a detergent composition. Foam is a significant consumer cue and acts as the primary reason by which a consumer perceives that a composition is having a cleaning effect.
- GB1169496 A (Unilever, 1969) discloses a detergent composition having controlled sudsing properties.
- the composition includes an anionic synthetic detergent, a nonionic synthetic detergent and/or a soap and an alkyl ether carboxylic acid.
- US5877140 (Hardy et al. 1999) discloses a detergent composition which includes LAS, soap, and an anionic compound to provide the dual performance benefits of excellent cleaning performance and suds suppression.
- GB1305540 A (Kao, 1973) discloses a foam controlled detergent composition having one or more anionic surface-active agents and specific fatty acid salt.
- WO 2017/055205 A1 discloses a carbonate built powder detergent composition having an anionic surfactant, nonionic surfactant and alkyl ether carboxylic acid dispersant.
- rinse triggered antifoams which act on the foam and suppresses it at the rinse stage.
- rinse triggered antifoam adds to the amount of chemicals incorporated in the composition and such compositions must be formulated carefully to avoid the antifoam being released during cleaning stage.
- rinse triggered antifoams are generally expensive and provide no other performance benefit to the composition other than foam suppression. Therefore, it is desirable that their presence is minimised.
- a detergent composition having specifically selected primary anionic detersive surfactant when present in combination with specific alkyl ether carboxylic acid cosurfactant and a foam suppressing agent selected from the group consisting of silicone compound, amino silicone compound, diester compound, a glycerol derivative, or mixtures thereof surprisingly provides good foam formation in the wash stage while eliminating the foam quickly during the rinsing stage. This benefit was preferably found across different consumer washing habits and fabric types present in the wash load. It was further preferably found that the detergent composition according to the first aspect of the present invention provides for removing the foam in a single rinse cycle.
- composition shows good foaming during the main wash and quick foam removal during the rinse stage; thus, the composition provides good sensorial and the advantage of lower water consumption.
- the present inventors have surprisingly found that the combination of the specific primary anionic surfactant and the alkyl ether carboxylic acid cosurfactant provides the solid detergent composition with quick foaming in the wash liquor even in presence of the foam suppressing agent and the quick removal of the foam in the rinse liquor.

- a second aspect of the present invention disclosed is method of treating a textile surface with the detergent composition according to the first aspect comprising the steps of: i) preparing a wash liquor with an effective amount of foam by contacting the detergent composition according to the first aspect with a liquid; ii) soaking said textile surface in the wash liquor for a predetermined period of time; and, iii) rinsing the textile surface, wherein the number of rinses required for the removal of foam present in the rinse liquor is less than 3 rinses.
- a primary anionic detersive surfactant selected from the group consisting of silicone compound, amino silicone compound, diester compound, a glycerol derivative, or mixtures thereof and a alkyl ether carboxylic acid cosurfactant having the general formula (I) according to the first aspect in a detergent composition to provide good lather generation in the wash liquor during the main wash stage and collapse of lather during rinse stage and wherein the rinse stage requires less than 3 rinses.

The glass cylinder is marked at 2 mL intervals and has a height of 14 inches from the inside of the bottom to the 250 mL mark. Next the cylinder was clamped in an automated cylinder shake (rotating device), which clamps the cylinder with respect to an axis of rotation that traverses the center of the graduated cylinder. a) The cylinder was rotated at a speed of 30 revolutions per minute. The cylinder was allowed to complete 5 full revolution and stopped at a vertical position. The height of the foam from the bottom was recorded in mL and provided in Table 2 below.

- the composition according to the present invention achieves quick foam reduction as compared to the Comp Ex B and is comparable to Comp Ex C.
- the above set of examples clearly show that the detergent composition according to the present invention exhibits good foam volume in the initial wash cycle and thereafter it also provides desirable low sudsing properties in the rinse stage which minimizes the wastage of clean water required for rinsing.
