DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to the field of multi-purpose cleaning compositions. Indeed, the present invention relates to the cleaning of different surfaces such as hard-surfaces, carpets or to any laundry applications including stains pretreatment.
BACKGROUND
A wide variety of cleaning compositions have been extensively described in the art. Typically, 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. Furthermore, 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.
This variety in formulation is rendered necessary by the difference in nature between the soils which can be found on laundry and on various surfaces in kitchens, floors and bathroom. For instance, kitchen soils comprise mainly edible oils, while bathroom soils comprise mainly sebum and soap scum, also limescale; floor soils comprise mainly particulate soils and laundry may have many different soils and stains.
However, there is a trend for the development of cleaning compositions with better performance in several respect, i.e. multi-purpose liquid cleaners which can be satisfactorily used on various surfaces as well as in laundry applications, to clean various soils and stains. Such multi-purpose compositions are, for example, disclosed in European patent application, EP-A-598973. Indeed, this patent application discloses 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.
But, it has been found that such 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 herein before, do not satisfactorily meet consumers 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. Although such 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, it has been found that when said hydrophobic nonionic surfactants are 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. Also, it has been found that there is a problem associated with the use of such ingredients, i.e. hydrophobic nonionic surfactants and 2-alkyl alkanols, in that they may cause the final product to appear hazy, indicating insolubility and phase separation.
It is thus an object of the present invention to formulate a multi-purpose liquid cleaner which can be satisfactorily used on various surfaces as well as in laundry applications, to clean various soils and stains. It is a further object of the present invention to provide such a composition which is a clear composition in a broad range of temperature, e.g. up to 50.degree. C.
