Definitions
- the invention relates to a hard surface cleaning composition which can be formulated as a light duty cleaner, hence providing at the same time cleaning benefits and shine; as an alternative, the compositions of the invention can be formulated as an all-purpose, heavy duty cleaner having superior cleaning properties.
- Hard surface cleaning compositions are well known in the art and their cleaning performances have been well improved over the years. While focusing on cleaning performances, essentially grease-cutting performance, a new problem has been encountered in that good shine results were not obtained with these compositions, unless the surface which had been cleaned had also been rinsed afterwards, i.e., that good shine performance was incompatible with good cleaning performance, in a non rinse-type hard surface cleaner. Indeed, when used, most compositions leave streaking traces and/or a residual film on the cleaned surfaces which, as a consequence, do not have a good appearance.
- Such problem is particularly a nuisance when the hard surface cleaner is used to clean windows or mirrors, because the residual film is even more apparent.
- US 3,591,510 discloses hard surface cleaners which contain surfactants possibly in the form of their ammonium salt, a solvent mixture, and a water soluble builder.
- GB 2 160 887 discloses a composition containing an anionic surfactant, water soluble and water insoluble alcohols and an organic solvent.
- J 62034998 discloses compositions containing an anionic surfactant salt, a water soluble solvent, sodium or potassium hydroxide, and monoethanolamine.
- J 58101198 discloses compositions containing alkanolamine, a mixture of anionic and nonionic surfactant and polypropylene glycol.
- the present invention is based on the discovery that piperazine, when used in the cleaning compositions disclosed hereinafter, provides outstanding cleaning performances without impairing the shine performance of said cleaning compositions.
- the invention provides hard surface cleaning compositions which comprise:
- compositions according to the invention comprise from 0.04% to 0.6% by weight of the total composition, preferably from 0.07% to 0.45% by weight of the total composition of a surfactant, or mixtures thereof; well-known synthetic anionic, nonionic, amphoteric and zwitterionic surfactants are suitable for use herein.
- a surfactant or mixtures thereof
- well-known synthetic anionic, nonionic, amphoteric and zwitterionic surfactants are suitable for use herein.
- these are the alkyl benzene sulfates and sulfonates, paraffin sulfonates, olefin sulfonates, alkoxylated (especially ethoxylated) alcohols and alkyl phenols, amine oxides, sulfonates of fatty acids and of fatty acid esters, and the like, which are well-known in the detergency art.
- such detersive surfactants contain an alkyl group in the C10-C18 range; the anionic detersive surfactants are most commonly used in the form of their sodium, potassium or triethanolammonium salts.
- the nonionics generally contain from 3 to 17 ethylene oxide groups per mole of hydrophobic moeity.
- the aninonic surfactants in the form of their ammonium salts.
- compositions of the invention also feature a solvent system, which consists of from 1.5% to 15% by weight of the total composition of an organic solvent, or mixtures thereof, which have a boiling point between 60°c and 190°c.
- Piperazine also referred to as diethylenediamine
- Piperazine is a well-known, commercially available compound, and both piperazine and its hydrated form (piperazine hexahydrate) are suitable for use herein.
- the compositions are advantageously supplemented with organic amines; said amines are volatile, i.e. they have a boiling point below about 150°c, are water-soluble and provide alkalinity, i.e. they have a pK b ⁇ 5.5; preferably, these amines will be also odorless.
- Preferred compounds according to the foregoing are monoethanolamine, diethanolamine, triethanolamine, or mixtures thereof. Highly preferred is monoethanolamine.
- compositions according to the invention may also contain builders.
- Suitable builders for use herein include nitrilotriacetates, polycarboxylates, nitrates, water soluble phosphates, silicates, ethylene diamine tetraacetate (EDTA), amino polyphosphonates, phospates and mixtures thereof.
- Other builders, which are highly preferred are the iminodiacetic builders; most preferred is 2-hydroxy iminodiacetic acid.
- composition of the invention may contain optionals at conventional levels; such optionals include perfumes, dyes, optical brighteners, thickeners, soil suspending agents, enzymes, freeze thaw, bactericides and preservatives.
- the compositions are formulated as light duty cleaners, i.e. cleaners which are suitable for a non-rinse use.
- the amount of piperazine in these light duty compositions is no more than 1% by weight of the compositions, preferably about 0.5% by weight of the total composition, and the solvent system is present in amounts of about 13% by weight of the total composition; these compositions may be free of builders, or may contain very low amounts of builders, since these are detrimental to the shine performance of cleaning compositions; typically, these compositions contain less than 0.25% by weight of the composition of builders.
- the compositions can be formulated as all-purpose cleaners, in which the cleaning performance is privileged over the shine properties.
- the amount of piperazine in the compositions can be as high as 3% by weight of the compositions; since a perfect shine is not a desired property of these compositions, the amount of builders can also be raised to about 3% by weight of the total composition.
- the following light duty composition is prepared by mixing all ingredients (percentages are by weight of total composition)
- This reference composition was then supplemented with 0.25%, 0.5% or 1% of piperazine, on top of said composition.
- These three compositions according to the invention were then compared the above reference composition (i.e. without any piperazine) both for their shine performance as well as for their cleaning performance.
- test conditions were as follows : All tests were run with the aid of an Erichsen washability machine. A sponge of approximately 9,5 x 5 x 4 cm was used after being carefully washed under hot running water and squeezed through drying rolls. 5g. of the undiluted cleanser to be tested on spread over one side of the sponge. The number of strokes of the cleaning machine needed to clean the plates were counted.
- the shine performance was evaluated on mirrors, using the compositions as a spray cleaner.
- the composition which is sprayed on the mirror is then wiped, using commercially available Domex R paper towel.
- NH4LAS ammonium salt of linear alkyl benzene sulfonate
- nBp stands for n-butoxypropanol
- nPp stands for n-propoxypropanol
- the builder used is 2-hydroxypropyl iminodiacetic acid
- the balance is made with water and minors.
- the following heavy duty composition is made by mixing the listed ingredients in the listed proportions.
- the abbreviations used are the same as in the previous examples.
