Definitions
- the present invention relates to the cleaning of different surfaces such as hard- surfaces, fabrics, clothes and the like.
- cleaning compositions have been extensively described in the art.
- cleaning compositions can be divided into hard surface cleaning compositions and laundry cleaning compositions.
- Cleaning compositions of these two types are traditionally very different in formulation and are sold as different products with different marketing concepts. These differences impose on the consumer to have to purchase and use at least two different products.
- compositions of the two types above, especially hard surface cleaners can be divided into sub-types. Indeed, many different kinds of hard- surface cleaners are available, for instance bathroom cleaners, kitchen cleaners or floor cleaners.
- kitchen soils comprise mainly edible oils
- bathroom soils comprise mainly sebum and soap scum, also limescale
- floor soils comprise mainly particulate soils and laundry may have many different soils/stains including greasy stains (e.g., olive oil, mayonnaise, vegetal oil make up), particulate stains and/or bleachable stains (e.g., tea, coffee).
- liquid aqueous cleaning compositions with better performance in several respect, i.e., liquid aqueous multi-purpose cleaners which can be satisfactorily used on various surfaces as well as in laundry applications, to clean various soils and stains.
- multipurpose compositions are, for example, disclosed in European patent application, EP-A-598973.
- this patent application discloses liquid aqueous compositions comprising hydrogen peroxide with a fully nonionic system, i.e., at least one nonionic with an HLB above 15, at least one nonionic with an HLB of from 13 to 15, at least one nonionic with an HLB of from 9 to 13 and at least one nonionic with an HLB below 9.
- This patent application further discloses the use of 2-alkyl alkanols as suds suppressors in said compositions.
- liquid aqueous compositions comprising hydrogen peroxide, a 2-alkyl alkanol and as the surfactant system, a specific nonionic system of at least four nonionic surfactants having different HLB (hydrophilic lipophilic balance) as defined hereinbefore, do not satisfactorily meet consumer's needs. Indeed, such compositions based on a fully nonionic surfactant system and comprising a high level of hydrophobic surfactants were found to have poor performance on some kind of stains in laundry application.
- HLB hydrophilic lipophilic balance
- hydrophobic nonionic surfactants have good grease cutting properties and are particularly effective on greasy soils having hydrophobic character, such as mineral oil and soap scum when used in hard surface cleaning composition
- hydrophobic nonionic surfactants when used in laundry applications bleachable stains are not satisfactorily bleached.
- the wettability of the fabrics stains is seriously affected by the hydrophobicity of the nonionic system of said compositions, i.e., good contact between hydrogen peroxide and the stains on said fabric is prevented resulting thereby in poor performance on bleachable stain.
- EP-A- 666 308 discloses compositions comprising hydrogen peroxide or a source thereof, a 2-alkyl alkanol, a hydrophobic surfactant having an HLB below 14 and an anionic surfactant.
- a multi-purpose liquid aqueous cleaning composition providing improved bleachable performance and improved stain removal performance especially on greasy stains, when used in laundry applications including laundry pretreatment applications, and/or in any household applications (e.g. cleaning of hard-surfaces typically found in kitchens or bathrooms).
- a liquid aqueous cleaning composition having a pH up to 7 and comprising a peroxygen bleach, at least an ethoxylated nonionic surfactant and at least a zwitterionic betaine surfactant at a weight ratio of the ethoxylated nonionic surfactant to the zwitterionic betaine surfactant of from 0.01 to 20.
- a multi-purpose liquid aqueous cleaning composition is provided which exhibits a great flexibility in the soils it may clean.
- such a composition when used for example in a laundry application, especially in a pretreatment application, boosts the removal of various types of stains including greasy stains like lipstick, olive oil, mayonnaise, vegetal oil, sebum, make-up, and more surprisingly the bleaching performance, as compared to the stain removal and bleaching performance delivered by the same composition comprising only one of these surfactants (i.e., ethoxylated nonionic surfactant or zwitterionic betaine surfactant) at equal total level of surfactants.
- these surfactants i.e., ethoxylated nonionic surfactant or zwitterionic betaine surfactant
- compositions of the present invention significantly boost the removal of kitchen dirt when used to clean hard-surfaces, as compared to the same compositions comprising only one of these surfactants (i.e., ethoxylated nonionic surfactant or zwitterionic betaine surfactant) at equal total level of surfactants.
- these surfactants i.e., ethoxylated nonionic surfactant or zwitterionic betaine surfactant
- the compositions of the present invention provide excellent stain removal performance on a broad range of stains and soils and excellent bleachable performance when used in any laundry application, e.g., as a laundry detergent or a laundry additive, and especially when used as a laundry pretreater, or even in other household applications like in hard surface cleaning applications.
- a further advantage is that the aqueous compositions herein are physically and chemically stable upon prolonged periods of storage.
- compositions according to the present invention are able to perform in a variety of conditions, i.e., in hard and soft water as well as when used neat or diluted.

- An adequate pressure is applied on the system to allow the salts to migrate from the surfactant raw material to the polar solvent phase. This way the zwitterionic betaine surfactant raw material is purified, i.e. the salts is subtracted from the raw material.
- the use of such salt free zwitterionic betaine surfactants delivers improved fabric safety and/or color safety when bleaching fabrics with a peroxygen bleach-containing composition comprising the same, as compared to the use of the same zwitterionic betaine surfactant raw materials with higher amount of salts.
- the present invention also encompasses the use of a composition comprising a salt free zwitterionic betaine surfactant and a peroxygen bleach for bleaching fabrics whereby color safety is improved (i.e. color damage/decoloration is reduced) and/or fabric safety is improved.
- the betaine zwitterionic surfactants herein have the ability to further boost the stain removal performance delivered by the ethoxylated nonionic surfactants herein on greasy stains, while providing improved bleaching performance to the liquid peroxygen bleach-containing compositions of the present invention comprising them.
- Optimum stain removal performance and bleaching performance are obtained when the ethoxylated nonionic surfactant and the zwitterionic betaine surfactant are present in the compositions of the present invention comprising a peroxygen bleach (pH up to 7), at weight ratio of the ethoxylated nonionic surfactant to the zwitterionic betaine surfactant of from 0.01 to 20, preferably from 0.1 to 15, more preferably from 0.5 to 5 and most preferably from 0.8 to 3.

- the present invention is based on the finding that the use of zwitterionic betaine surfactant on top of the ethoxylated nonionic surfactant at the appropriate ratios, in a liquid aqueous composition comprising a peroxygen bleach (pH up to 7), boosts the bleaching performance and the removal of various types of stains including greasy stains (e.g., lipstick, olive oil, mayonnaise, vegetal oil, sebum, make-up), as compared to the bleaching and stain removal performance delivered by the same composition based only on one of these surfactants (i.e., ethoxylated nonionic surfactant or zwitterionic betaine surfactant) at equal total level of surfactants.
- a peroxygen bleach pH up to 7
- the improved stain removal benefit and bleaching benefit are delivered with a liquid aqueous composition which is a water-like, clear and transparent composition.
- the appearance of a composition can be evaluated via turbidimetric analysis.
- the transparency of a composition can be evaluated by measuring its absorbency via a spectrophotometer at 800 nm wave length.
- the stain removal performance may be evaluated by the following test methods on various type of stains.
- a suitable test method for evaluating the stain removal performance on a soiled fabric for example under pretreatment condition is the following: A composition according to the present invention is applied neat to a fabric preferably to the soiled portion of the fabric, left to act from 1 to 10 minutes, and said pretreated fabric is then washed according to common washing conditions, at a temperature of from 30° to 70°C for from 10 to 100 minutes. The stain removal is then evaluated by comparing side by side the soiled fabric pretreated with the composition of the present invention with those pretreated with the reference, e.g., the same composition but comprising only an alkoxylated nonionic surfactant or only a zwitterionic betaine surfactant as the sole surfactant.
- a visual grading may be used to assign difference in panel units (psu) in a range from 0 to 4.
- a suitable test method for evaluating cleaning performance on a hard-surface is the following: synthetic soil representative of typical hard surface household kitchen dirt soil can be used.
- the test-soil is applied on an enamel-coated metal plate (cleaned with a detergent and then with alcohol) with a paint roller, and the plates are baked at 130° C for 30 minutes. After 24 hours they can be used for the test.
- This test is evaluated in a Gardner straight-line scrub machine. The results are given in number of strokes a given composition needs to clean a standard soiled plate. The lower the number of strokes needed the more efficient in terms of satin removal is the composition used to clean the dirt from the test plates.
- the bleaching performance may be evaluated as for the stain removal performance but the stains used are bleachable stains like coffee, tea and the like.
- An advantage of the liquid aqueous compositions of the present invention is that they are physically and chemically stable upon prolonged periods of storage.
- Chemical stability of the compositions herein may be evaluated by measuring the concentration of available oxygen (often abbreviated to AvO2) at given storage time after having manufactured the compositions.
- concentration of available oxygen can be measured by chemical titration methods known in the art, such as the iodometric method, thiosulphatimetric method, the permanganometric method and the cerimetric method. Said methods and the criteria for the choice of the appropriate method are described for example in "Hydrogen Peroxide", W. C. Schumb, C. N. Satterfield and R. L. Wentworth, Reinhold Publishing Corporation, New York, 1955 and Organic Peroxides", Daniel Swern, Editor Wiley Int. Science, 1970.

- the ionic strength of the compositions is higher than 1.10 "4 M, preferably higher than 5.10 _ 3 M, and more preferably higher than 1.10 _ 3 M. Indeed, it has been observed that formulating the compositions of the present invention with such high ionic strength further contributes to their benefits, i.e., improved stain removal performance and improved bleaching performance. The higher the ionic strength the better the stain removal and bleaching performance.
- the ionic strength of a composition may be increased by the addition of various ingredients like chelating agents or mixtures thereof.
- compositions of the present invention may comprise a chelating agent as a preferred optional ingredient.

- a chelating agent may be desired in the compositions of the present invention as it allows to increase the ionic strength of the compositions herein and thus their stain removal and bleaching performance on various surfaces.
- the presence of chelating agents may also contribute to reduce tensile strength loss of fabrics and/or color damage, especially in a laundry pretreatment application. Indeed, the chelating agents inactivate the metal ions present on the surface of the fabrics and/or in the cleaning compositions (neat or diluted) that otherwise would contribute to the radical decomposition of the peroxygen bleach.
