Definitions

• the present invention relates to the field of detergent or cleaning compositions.
• the compositions of the present invention are multi-purpose cleaning compositions which are suitable for use as hard-surface cleaners, carpet cleaners as well as in laundry applications.
• cleaning compositions have been 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
• This vanety in formulation is rendered necessary by the difference in nature between the soils which can be found on laundry and on va ⁇ ous surfaces in kitchens, floors including carpets and bathroom.
• kitchen soils comprise mainly edible oils
• bathroom soils comprise mainly sebum and soap scum, also limescale
• floor soils compnse mainly particulate soils and laundry may have many different soils and stains.
• compositions according to the present invention should also be able to perform in a vanety of conditions, i.e. in hard and soft water. They should also provide satisfactory shine performance and surface safety when used as hard surface cleaners.
• the present invention is an aqueous cleaning composition having a pH of from 0.5 to 6, said composition comprising from 2% to 40% by weight of the total composition of a nonionic surfactant system, whereby said nonionic surfactant system comprises:
• At least one nonionic surfactant with an HLB of from 9 to 13 At least one nonionic surfactant with an HLB below 9
• compositions according to the present invention are aqueous liquid cleaning compositions.
• Said aqueous compositions have a pH as is of from 0.5 to 6, preferably 1 to 5, most preferably from 2 to 4.5.
• the pH of the compositions can be adjusted by using organic or inorganic acids, or alkalinizing agents.
• compositions according to the present invention further comprise a specific nonionic surfactant system comprising at least four nonionic surfactants.
• Said nonionic surfactant system is efficient in cleaning a variety of different soils, and significant cooperation has been observed between the four different types of surfactants.
• the nonionic surfactant system herein comprises a mixture of at least four different nonionic surfactants, each of which lies in a specified HLB (hydrophilic-lipophilic balance) range.
• HLB hydrophilic-lipophilic balance
• nonionic surfactant system according to the present invention comprises:
• Suitable highly hydrophobic surfactants for use herein are Dobanol R 23-3, Lutensol R A03, Dobanol R 91-2.5 and Dobanol R 23-2.
• compositions according to the present invention said nonionic surfactants belonging to the four classes described hereinabove act in synergy, particularly on kitchen dirt soils and bathtub soils. It is thus possible to use low total levels of said nonionic surfactant system.
• the compositions according to the present invention comprise from 40% down to 2% by weight of the total composition of said nonionic surfactant system, preferably from 15% to 3%.
• nonionic surfactant system wherein the weight ratio of highly hydrophilic surfactant to hydrophilic surfactant is at most 1 :1.5, and wherein the combined amount of said highly hydrophilic and hydrophilic surfactant in the total composition is at least 2% by weight, preferably at least 2.5%.
• nonionic surfactant system wherein the weight ratio of highly hydrophobic to hydrophobic surfactant is from 1.5:1 to 2.5:1 , preferably 2:1 , and wherein the combined amount of said hydrophobic and highly hydrophobic nonionic surfactant in the total composition is at least 1.5% by weight.
• compositions according to the present invention may further comprise additional nonionic surfactants, i.e. there can be more than one surfactant in each class hereinabove.
• additional nonionic surfactants i.e. there can be more than one surfactant in each class hereinabove.
• the compositions according to the present invention do not require the use of an anionic surfactant system. Accordingly, the compositions according to the present invention are preferably free of anionic surfactants.
• compositions herein presents a good suds profile and therefore does not require the use of a suds suppressing ingredient. It has been found that, for an optimum suds profile, it is preferable to use a nonionic surfactant system according to the present invention wherein the weight ratio of the sum of the highly hydrophilic and hydrophilic surfactants to the highly hydrophobic surfactant is of 1.5:1 or more.
• suds suppressing systems such as 2-alkyl alkanols, as described for instance in DE 40 21 265 and co-pending European patent application 92870174.7.
• suitable compounds are commercially available, for instance in the ISOFOL ( ⁇ > series such as ISOFOL @ 12 (2-butyl octanol) and ISOFOL @ 16 (2-hexyl decanol).
• Preferred 2-alkyl alkanols for use herein have an alkyl chain comprising from 6 to 16 cartoon atoms, preferably 8 to 12, and a terminal hydroxy group, said alkyl chain being substituted in the ⁇ position by an alkyl chain comprising from 1 to 10 carbon atoms, preferably 2 to 8, more preferably 3 to 6.
• an alkyl chain comprising from 1 to 10 carbon atoms, preferably 2 to 8, more preferably 3 to 6.
• the selected brighteners belong to the class of distyryl diphenyl brighteners, in particular 4-4'-bis [2-2' styryl sulfonate] biphenyl, commercially available from Ciba-Geigy under the trade name Tinopal CBS-X @.
• the appropriate amount of brightener to be used depends on the particulars of the surfactant system and the 2-alkyl alkanol chosen, but can be determined by simple trial and error.
• compositions herein preferably comprise from 2% to 15% by weight of the total composition of hydrogen peroxide or a source thereof.
• the presence of hydrogen peroxide provides strong cleaning benefits which are particularly noticeable in laundry applications.
• the nonionic surfactant system for use in the compositions according to the present invention is remarkably compatible with hydrogen peroxide in that good hydrogen peroxide storage stability was observed, even in the absence of hydrogen peroxide stabilizers.
• ingredients which are typically sensitive to hydrogen peroxide such as dyes or brighteners, appear to be stable upon storage in the compositions according to the present invention without having to add stabilizers for that purpose.
• the compositions according to the present invention may further comprise a variety of optional ingredients such as builders, solvents, perfumes and dyes.
• compositions according to the present invention can be used as a household cleaner in the bathroom or in the kitchen, and can also be used as a laundry detergent or as a laundry detergent booster.
• the compositions according to the present invention are easy to rinse and provide good shine characteristics on the cleaned surfaces.
• the compositions according to the present invention, especially when formulated with hydrogen peroxide, are also particularly effective as carpet cleaners. If used as carpet cleaners, the compositions according to the present invention are advantageously dispensed with a spray dispenser and left to act on said carpets.
• compositions were made by mixing the listed ingredients in the listed proportions (weight % unless otherwise specified).
• the compositions in the examples were tested and proved satisfactory on cleaning laundry, kitchen dirt soils as well as bathtub soils. Furthermore, the stability of hydrogen peroxide, brightener and dye was monitored and proved satisfactory at 50°c for two weeks.
• compositions were clear products with more than 90% transmittance at 600nm at room temperature.
