Definitions
- the present invention relates to acidic cleaning compositions, and in particular to acidic antimicrobial cleaning composition suitable for use on hard surfaces.
- compositions generally comprise sufficient acid to give a low pH and may comprise a thickening agent to as to cause the composition to be retained on sloping surfaces, such as the inside of toilet bowls.
- thickeners include both ethoxylated and unethoxylated tertiary amines, either alone or in combination with a hydrotrope.
- acids for use in such compositions include sulphamic and phosphoric acids.
- GB 1443244 relates to acid cleaners and descalers which comprise as a thickening agent an ethoxylated tertiary amine of which ETHOMEEN S12 (N,N-dihydroxyethyl-oleylamine) is given as an example.
- the composition also comprises acids which are selected from mineral acids and acid salts of strong inorganic acids such as sulphamic acid. Bacteriocides are an additional, optional component.
- FR 2459830 discloses compositions which comprise non- ethoxylated and ethoxylated amines together with sulphamic acid.
- the composition may also comprise disinfectants.
- AU-A-57022/86 relates to cleaning systems which comprise a mixture of sulphamic and phosphoric acids and an acid stable surfactant.
- Bacteriocides are optional and formalin is disclosed as a bacteriocide which improves the antibacterial effect of the acids.
- EP-B-0276501 discloses thickened aqueous cleaning compositions which comprise 0.1-50%wt of a weak acid having a pK >2 (of which sulphamic acid is given as an example) , 0.1-20%wt of an amine which can include 2% of oleyl-bis(2- hydroxyethy1 ) amine and 0.01%-5%wt hydrotrope (sodium xylene-sulphonate is given as an example) . Disinfecting agents are optional .
- EP-A-0314232 relates to compositions which undergo a viscosity increase on dilution and discloses that thickened liquid detergent compositions can be prepared with an amine oxide, amine (such as ETHOMEEN S12) , betaine or quaternary ammonium compound and hydrotrope (sodium xylene- sulphonate) . It is stated in the specification that amine oxides and quaternary ammonium compounds are known to have biocidal properties and that further microbiocides including organic peracids are optional. These compositions can be of acidic, neutral or alkaline pH.
- One problem with the known compositions is that the viscosity of the compositions drifts with time, and, in particular falls when the product is stored.
- compositions which comprise a specific mixture of both saturated and unsaturated alkoxylated aliphatic amines in the presence of an anionic surfactant show an improved stability of viscosity on storage.
- anionic surfactant hydrotrope to these formulations has the additional benefit that the surface energy of surfaces treated with the composition is reduced and the subsequent deposition of limescale is retarded.
- a cleaning composition which comprises a) 0.01-15%wt an alkoxylated aliphatic amine with 8-18 carbon atoms and 1-8 moles ethoxylation wherein the mole ratio of saturated to unsaturated aliphatic residues falls in the range 40:60 to 80:20, and
- a process for retarding the deposition of limescale on a surface which comprises the step of treating said surface with a cleaning composition having a pH of less than 1 which comprises:
- the alkoxylated aliphatic amine is an ethoxylated tertiary amine of the general formula:
- R is an alkyl or alkenyl group comprising 8-18 carbon atoms
- A is an ethoxy or propoxy group
- x and y may be the same or different and are integers from 1-3.
- the preferred materials are ethoxylated amines wherein A is -OCH 2 CH 2 - .
- R is mixed saturated and unsaturated C14-C18 alkyl and is most preferably derived from fatty acids residues of which the majority correspond to oleic and/or stearic acids.
- the mole ratio of saturated to unsaturated fatty acids falls into the range 50:50 to 66:33.
- a particularly suitable alkoxylated aliphatic amine is a material known as ETHOMEEN BTB/12TM, available from AKZO.
- BTB/12 is believed to be a mixture of material derived from fully hardened tallow and the oleyl derivative in a 65/35 ratio.
- Such a mixed material can be prepared by synethesis using an appropriate ratio of mixed starting materials or obtained by mixing an alkoxylated aliphatic amine such as
- ETHOMEEN S12 (ex AKZO) is N,N- (dihydroxyethyl ) -oleylamine .
- the preferred levels of the alkoxylated aliphatic amine are l-10%wt on product with levels of 2-6%wt on product being particularly preferred.
- the alkoxylated aliphatic amine is present together with an anionic surfactant.
- the levels of these materials are such that they interact so as to thicken the composition
- Suitable anionic surfactants include the sulphonate hydrotropes.
- Preferred surfactants are alkylarylsulphonates such as salts, particularly alkali metal salts, of toluene, cumene or xylene sulphonate .
- the preferred anionic surfactant is sodium cumenesulphonate .
- TM is ELTESOL SC 40 (ex. Albright and Wilson) .
- Typical levels of anionic surfactant range from 0.05-2%wt on product.
- formulations comprising the alkylaryl sulphonates are formulated at a pH below 1.
- the ethoxylated amine behaves as a cationic surfactant and interacts with the alkylaryl sulphonate to form a water- insoluble gel which deposits as a monolayer on surfaces. It is believed that this monolayer lowers the surface energy of the surface and retards or prevents the deposition of further limescale.
- the preferred mole ratio of the ethoxylated amine and the anionic surfactant is 3-3.5, more preferably 3.25-3.5.
- the preferred viscosity of the cleaning compositions according to the present invention is between 50 mPas and 1000 mPas when measured at 11.7 sec shear and at 25°C using Haake RV2 rotoviscometer (RTM) and an MVl bob
- cleaning compositions which embody the present invention comprise 0.01-15%wt of a limescale removing acid, preferably an organic acid and more preferably sulphamic acid.
- a limescale removing acid preferably an organic acid and more preferably sulphamic acid.
