Description

Detergent composition comprising isethionate surfactant

Field of the invention

The present invention relates to a fabric cleaning composition; in particular a solid laundry detergent composition having a desirable foam profile during the laundering process.

Background of the invention

Synthetic detergents are widely used for laundering fabrics, due to the efficiency of these detergent compositions in cleaning and stain removal. In addition to the synthetic detergents, formulated laundry detergent composition includes various additives to provide improved cleaning and sensorial benefits. One of the sensorial benefits include maintaining a proper level of foam during the laundering process.

Foaming, or sudsing, of detergents is an extremely 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. Unfortunately, while foam is easy to generate, it also needs to be removed from the substrate after cleaning. High volume of foam in the washing cycle typically results in foam being carried over to the rinse solution and requiring additional time, energy and water to thoroughly rinse the laundered articles. It is therefore advantageous to have high foam volume generation at early stages in the wash cycle for consumer acceptance. Thereafter, quick collapse of the foam to a lower volume toward the end of the wash cycle is another preferred aspect of the foaming profile of a detergent composition for complete cleaning and minimum wastage of clean water.

Several attempts at saving water after laundering textile articles with high foaming compositions have been made in the past. Laundry formulations such as rinse aids have been used to help reduce the foam carried by the laundered fabric into the rinse water. Rinse aids reduce the amount of water used during rinsing. However, the use of rinse aids adds an extra step and the consume needs to use an additional product in the washing process. In today’s fast paced world, consumers look for a single composition which provides multiple benefits. Accordingly, there is a need for a detergent composition which provides good foam profile, good cleaning benefits and reduces water consumption. This need is particularly felt by consumers who dwell in regions where there is acute shortage of water.

In recent years, use of synthetic detergents have been associated with adversely affecting the environment as these foaming ingredients are derived from nonrenewable resources and pollute water bodies when the synthetic detergents are ultimately discharged into rivers and lakes. Thus, there is a need for a detergent composition which has lower levels of these ingredients. However, one difficulty in meeting this need is that the reduction of surfactant in a detergent composition significantly deteriorates the foaming profile of the detergent composition, these compositions may provide low foam generation, or foam which may not be well retained during the washing cycle. Such a detergent composition with poor foaming profile becomes less acceptable to consumers who highly value the foaming profile of the detergent composition.

Accordingly, there remains a need for a laundry cleaning composition containing an environmentally friendly composition with lower levels of synthetic detergents while providing desired foaming profile, i.e. a high volume of well retained foam generated quickly upon dissolving the detergent composition in a washing solution and which quickly collapses towards the end of the washing cycle to aid in easier removal of foam at the rinse stage .

Thus, there is a need for a cleaning composition that reduces and preferably eliminates foam in the rinse without adversely affecting the formation of foam in the initial washing step.

Some solutions towards addressing this problem of foaming at the rinse stage, were provided by incorporating rinse triggered antifoams which act on the foam and suppresses it at the rinse stage. However, such 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.

Further such 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.

In the past, compositions to deliver reduced foaming have been made.

One such composition is disclosed in US 2017/0292088 A1 (The Honest Company, Inc) which provides a laundry detergent composition which prevents excessive foaming which takes place in a washing machine during agitation. The detergent composition includes alkyl isethionate as the surfactant and a defoaming agent.

Despite the efforts made in the past towards providing detergent composition for laundering fabrics which provides desired foam profile at different laundering steps there continues to be a need for a solid cleaning composition which provides good foam profile while maintaining good cleaning performance.

It is thus an object of the present invention to provide a solid laundry detergent composition which provides good foam profile.

It is another object of the present invention to provide a solid laundry detergent composition which provides good cleaning performance.

It is yet another object of the present invention to provide a solid laundry detergent composition which is environmentally friendly.

It is yet another objection of the present invention to provide a solid laundry detergent composition which reduces the amount of water required for rinsing.

Summary of the invention

According to a second aspect the method includes the step of preparing an aqueous wash liquor of the detergent composition in a liquid. The wash liquor is preferably prepared by dissolving the detergent composition in water. In the next step, preferably the textile surface is subjected to a washing step prior to the aforementioned optional rinsing step. For purposes of the present invention, washing includes, but is not limited to, scrubbing, wiping and mechanical agitation. The compositions are preferably employed at concentrations of from about 200 ppm to about 10,000 ppm in solution. The water temperatures preferably range from about 5°C to about 100°C. Machine laundry methods herein typically comprise treating soiled laundry with an aqueous wash solution in a washing machine having dissolved or dispensed therein an effective amount of the detergent composition in accordance with the invention. By an effective amount of the detergent composition it is meant from 20 g to 300 g of product dissolved or dispersed in a wash solution of volume from 5 to 65 liters, as are typical product dosages and wash solution volumes commonly employed in conventional machine laundry methods. Hand-washing methods, and combined handwashing with semiautomatic washing machines are also included. According to a third aspect of the present invention disclosed is the use of isethionate surfactant, a foam suppressing agent, an anionic non-soap non-isethionate surfactant selected from the group consisting of alkyl sulphonate surfactant, alkyl sulphate surfactant, alkoxylated sulphate surfactant or combinations thereof and a sodium carbonate builder wherein the ratio of the isethionate surfactant to anionic non- isethionate surfactant is in the ratio from 1:1to 1:160 in a detergent composition to provide fast lather generation in the wash liquor during the main wash stage and rapid collapse of lather during rinse stage. The invention will now be illustrated more fully with the aid of the following non-limiting examples. It will be appreciated that other modifications of the present invention within the skill of those in the art can be undertaken without departing from the spirit and scope of this invention. All of the formulations exemplified hereinafter are prepared via conventional formulation and mixing methods unless specific methods are given. All parts, percentages, and ratios herein are by weight unless otherwise specified. Some components may come from suppliers as dilute solutions. The levels given reflect the weight percent of the active material, unless otherwise specified. The excluded diluents and other materials are included as "Minors". Examples Example 1 Different comparative detergent compositions and detergent composition according to the present invention were prepared having the ingredients as provided in Table 1. The detergent compositions used are as follows: Comparative Example (Comp A): This is a solid laundry detergent composition which includes anionic surfactant (LAS) and a sodium carbonate builder but is without an isethionate surfactant (SCI) and does not include a foam suppressing agent (silicone oil). Comparative Example (Comp B): This is a solid laundry detergent composition which includes an anionic surfactant (LAS), a sodium carbonate builder and an isethionate surfactant (SCI) but without a foam suppressing agent (silicone oil). Comparative Example (Comp C): This is a solid detergent composition which includes an anionic surfactant (LAS), a sodium carbonate builder and a foam suppressing agent (silicone oil) but without an isethionate surfactant (SCI). Example according to the present invention (Ex 1): This is a solid detergent composition which includes an anionic surfactant (LAS), a sodium carbonate builder, a foam suppressing agent (silicone oil) and an isethionate surfactant (SCI). Foam measurement method: The foam volume generated by the various solid laundry detergent composition as described above was measured using the automated cylinder shake protocol. Automated cylinder shake protocol: In this protocol firstly a known amount of the detergent powder was added in a beaker containing water to form a 3gpl wash liquor. The water had a hardness of 24° FH (Ca:Mg, 2:1). The beaker was placed on a magnetic stirrer for 20 minutes at a speed of 150 rpm for complete dissolution of the detergent composition in water to form an aqueous liquor (AL). A. In a first set of foam measurement, 40 mL of the aqueous liquor (AL) formed above was taken in a 250 mL stoppered graduated glass cylinder. 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 1 below. b) After noting the foam height, the cylinder was again rotated and was allowed to complete 5 more revolutions and thereafter stopped at a vertical position. The height of the foam after the 10 revolutions was measured from the bottom and recorded in mL, the measured foam height provided in Table 1 below. B. In a second set of foam measurement, 4 mL of the prepared aqueous liquor (AL) was taken in the 250 mL stoppered graduated glass cylinder. To this 36 mL of water was added. The water had a hardness of 24° FH (Ca:Mg, 2:1). Next the cylinder was clamped in an automated cylinder shake (rotating device) and rotated for 5 revolutions and 10 revolutions respectively as described above and the measured foam height were recorded and provided in Table 1 below. In the rest time between the first and the second sequence of 5 rotations in this set of experiment is maintained the same way as in the first set of experiment. The foam measurement was similarly followed for all the compositions provided in table 1 to 3 below.

As shown in the data, in the first set of experiment which is demonstrative of the main wash stage in a laundering process in which the consumers desired foam, the detergent composition according to the present invention shows good foam as compared to the comp A (LAS without foam suppressing agent) and Comp C (LAS with foam suppressing agent). The detergent composition according to the present invention which includes a foam suppressing agent shows similar foam profile as that of Comp B (surfactant without foam suppressing agent) In the 2^nd set of experiments which is demonstrative of the rinse stage in a laundering process where the foam needs to be removed, it is shown that the composition according to the present invention achieves quick foam reduction as compared to the Comp A or Comp B. Thus, 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. Example 2: Foam profile of solid laundry detergent composition with different ratio ranges between the isethionate surfactant and the anionic non-isethionate surfactant

As shown in table 2, the composition according to the present invention having a ratio between the isethionate surfactant to the anionic non-isethionate surfactant of 1:90 (Inventive 2) shows good foam in the wash liquor and quick foam reduction in the rinse stage.

As shown in table 3, the composition according to the present invention having a ratio between the isethionate surfactant to the anionic non-isethionate surfactant of 1:9 (Inventive 3) shows good foam in the wash liquor and quick foam reduction in the rinse stage. Thus, 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.
