- Suitable cationic surfactants can be found among quaternary ammonium salts having one or two alkyl or aralkyl groups of from 8 to 20 carbon atoms and two or three small aliphatic (e.g. methyl) groups, for instance cetyltrimethylammonium chloride.
- a specific group of surfactants are the tertiary amines obtained by condensation of ethylene and/or propylene oxide with long chain aliphatic amines.
- the compounds behave like nonionic surfactants in alkaline medium and like cationic surfactants in acid medium.
- Suitable zwitterionic surfactants can be found among derivatives of aliphatic quaternary ammonium, sulphonium and phosphonium compounds having an aliphatic group of from 8 to 18 carbon atoms and an aliphatic group substituted by an anionic water-solubilising group, for instance betaine and betaine derivatives such as alkyl betaine, in particular C 12 -C 16 alkyl betaine, 3-(N,N-dimethyl-N-hexadecylammonium)-propane-1-sulphonate betaine, 3-(dodecylmethyl-sulphonium)-propahe-1-sulphonate betaine, 3-(cetylmethyl-phosphonium)-propane-1-sulphonate betaine and N,N-dimethyl-N-dodecyl-glycine.
- betaines are the alkylamidopropyl betaines e.g. those wherein the alkylamido group is derived
- surfactants are compounds commonly used as surface-active agents given in the well-known textbooks: 'Surface Active Agents' Vol.1, by Schwartz & Perry, Interscience 1949 ; 'Surface Active Agents' Vol.2 by Schwartz, Perry & Berch, Interscience 1958 ; the current edition of 'McCutcheon's Emulsifiers and Detergents' published by Manufacturing Confectioners Company ; 'Tenside-Taschenbuch', H. Stache, 2nd Edn., Carl Hauser Verlag, 1981 .
- the composition according to the invention has a pH of from 2 to 13, more preferably at least 3, and not more than 12.
- Cleaning methods of the invention intended for cleaning kitchen hard surfaces may advantageously be carried out at a pH in the alkaline range.
- the method of the invention is carried out either at a pH between roughly 6.0 and 12, more preferred between 7.0 and 10.
- the pH of the cleaning composition used in the method of the invention may be adjusted with organic or inorganic acids or bases.
- Preferred inorganic bases are preferably alkali or alkaline earth hydroxides, ammonia, carbonates or bicarbonates, the alkali metal preferably being sodium or potassium or the alkaline earth metal preferably being calcium or magnesium.
- the organic bases are preferably amines, alkanolamines and other suitable amino compounds.
- Inorganic acids may include hydrochloric acid, sulphuric acid or phosphoric acid, and organic acids may include acetic acid, citric acid or formic acid as well as dicarboxylic acid mixtures such as Radimix (trade mark, Radici Group) and Sokalan DCS (trade mark, BASF).
- the cleaning composition used according to the present invention may include abrasives.
- the composition used according to the present invention does not contain an abrasive.
- the compositions may contain other ingredients which aid in their cleaning performance. For example, they may contain detergent builders and mixtures of builders in an amount of up to 25%, in particular when the composition contains one or more anionic surfactants.
- the builder preferably will form at least 0.1 % of the cleaning composition.
- Suitable inorganic and organic builders are well known to those skilled in the art.
- a further optional ingredient for compositions used according to the invention is a suds regulating material, which can be employed in compositions which have a tendency to produce excessive suds in use.
- a suds regulating material which can be employed in compositions which have a tendency to produce excessive suds in use.
- Soaps are salts of fatty acids and include alkali metal soaps such as the sodium, potassium and ammonium salts of fatty acids containing from about 8 to about 24 carbon atoms, and preferably from about 10 to about 20 carbon atoms. Particularly useful are the sodium and potassium and mono-, di- and triethanolamine salts of the mixtures of fatty acids derived from palm oil, coconut oil and ground nut oil. When employed, the amount of fatty acid or soap can form at least 0.005%, preferably 0.1% to 2% by weight of the composition.
