Description

[Detailed description of the invention]

FIELD OF THE INVENTION This invention relates to liquid detergent compositions, particularly for cleaning hard surfaces. Liquid detergent compositions for cleaning hard surfaces can generally be classified into two types. The first type of composition is a composition in the form of a suspension in water containing hand-sensible water-insoluble abrasive particles. Such compositions are prone to stability problems and have a sandy feel when used, which can be scratchy to the surfaces being cleaned. A second type of composition is a liquid detergent composition that generally contains soaps, fatty alkanolamides, alkylbenzene sulfonates, etc., but does not contain hand-sensible abrasive particles. Although detergent compositions of the latter type are not likely to scratch the surface being cleaned, they also have some drawbacks, which can cause some consumer dissatisfaction. For example, because they generally contain no or only small amounts of detergent builders, they tend to have low detergency against fine soils, especially in hard water areas. There may also be cases where homogeneity and viscosity are insufficient when this is used. Furthermore, when a high concentration of a surfactant is added to remove grease or fatty stains, the amount of foaming increases significantly, requiring sufficient wiping and rinsing to remove the foam.
This requires a great deal of effort and time. Although large amounts of foaming can be suppressed to some extent by the addition of foam suppressants such as hydrophobic silica and/or silicone (silicon resins) or soaps, this addition results in poor stability and homogeneity of the detergent composition. As a result, insoluble particles or soap residue may be deposited on the surface to be cleaned, and after the surface is dried, streaks or spots of residue may appear.

contains one or more organic acids selected from glycolic acid, lactic acid, citric acid, malic acid, malonic acid, etc., a surfactant, and a water-soluble solvent such as diethylene glycol monobutyl ether. A bathroom detergent composition is disclosed. However, the above-mentioned publication states that when these organic acids and other organic acids were compared with each other, the effects of succinic acid were poor, and for this reason, succinic acid was excluded. In a detergent composition for cleaning hard surfaces, when an organic acid having a longer carbon chain and lower solubility in water than the organic acid described in JP-A-52-77111 mentioned above is selected and blended. It has now been discovered that the cleaning power of this detergent composition is even better. The present invention therefore comprises, in addition to water, the following components: (a) 0.2-20% by weight of a cleaning active compound or a mixture thereof selected from synthetic anionic and nonionic cleaning active compounds; (b) One or more water-soluble dicarboxylic acids containing 5-7 carbon atoms in the molecule and having a solubility in water (20°C) of 1-70 g/100 g (water)

It is generally preferred to formulate both anionic and nonionic detergent active compounds selected to provide liquid compositions, ie, thickened compositions without the need for the use of thickening agents. The amount of detersive active compounds incorporated into the compositions of the invention is generally 0.2-20% by weight, preferably 2-10% by weight.

By selecting and using dicarboxylic acids with the above characteristics, the cleaning power of the composition is improved and the tendency to form residual stains and streaks is reduced (spots and streaks are caused by excessive foaming). ). Compared to similar compositions containing conventional detergent builders such as other organic acids, the compositions of the present invention provide better cleaning power and reduce the formation of spots and streaks when used to clean surfaces to be cleaned. It was confirmed that the trend was even lower. Preferred dicarboxylic acids have 5-7 carbon atoms in the molecule and have a solubility in water (20°C) of 1-70 g/

Table: Dicarboxylic acids with longer carbon chains than pimelic acid (such as suberic acid, which contains 8 carbon atoms in the molecule) have very low solubility in water, so they are not useful detergent builders. Regarding dicarboxylic acids with carbon chains shorter than glutaric acid (for example, succinic acid, which has 4 carbon atoms in the molecule), it does not have sufficient potency as a detergent builder in itself; The preferred dicarboxylic acids can be incorporated into the compositions of the present invention to enhance their effectiveness.

Optional Ingredients The composition of the present invention may contain a variety of other ingredients that help improve its cleaning power. For example, the composition may contain, in addition to the dicarboxylic acid having 5-7 carbon atoms in the molecule, various other detergent builders. However, these detergent builders must not reduce the detergency of the composition or increase the number of spots and streaks mentioned above. Examples of preferred detergent builders include nitrilotriacetates, polycarboxylates, citrates, water-soluble phosphates, especially polyphosphates, ortho- and pyro-
Mention may be made of mixtures of phosphates, zeolites, and mixtures of these builders. Sequestering agents can also optionally be used, including ethylenediaminetetraacetate, amino-polyphosphonates and phosphates (DEQUEST), and a wide variety of other polyfunctional organic acids and their salts. can be given. The amount of the builder and/or sequestering agent other than the specific dicarboxylic acid mentioned above is preferably 0.1-25% by weight (based on the total amount of the composition). The composition of the present invention may further contain soap as another optional ingredient. Soaps, however, have compositions that tend to produce excessive amounts of suds upon use.
It can be added as a foaming inhibitor. Soaps are salts of fatty acids, examples include alkali metal soaps such as sodium and potassium salts of higher fatty acids having preferably 8-24 and most preferably 10-20 carbon atoms, as well as ammonium salts and Examples include soaps such as alkanol ammonium salts.

Generally, the amount of soap present is at least 0.005% by weight, preferably 0.5-2% by weight (based on the total weight of the composition). Furthermore, the compositions of the invention may optionally contain thickeners (thickeners). The thickening agent helps improve the adhesion and distribution of the composition to the surface to be cleaned. Examples of preferred thickening agents include xanthan gum and other non-clotting thickening agents (eg, "Biopolymer PS83") (see US Pat. No. 4,329,448). The amount of the thickening agent incorporated into the composition of the present invention is:
The amount may be as small as 0.001% by weight, but preferably 0.01-3% by weight (based on the total amount of the composition). The compositions of the invention may also contain at least partially esterified resins. Examples of such resins include at least partially esterified adducts formed by the reaction of rosin with unsaturated dicarboxylic acids or their anhydrides, and monounsaturated aliphatic, cyclic, non-carboxyl-free resins. Examples include at least partially esterified derivatives derived from copolymer products of formula aliphatic or aromatic monomers and unsaturated dicarboxylic acids or their anhydrides. Preferred examples of copolymers of the latter type include copolymers of ethylene, styrene or vinyl methyl ether with maleic acid, fumaric acid, itaconic acid, citraconic acid, etc. or anhydrides thereof.
Styrene/maleic anhydride copolymers are preferred. Generally, the compositions of the present invention optionally contain at least partially esterified resin in an amount of 0.005-20% by weight, preferably 0.1-15% by weight, more preferably
It may contain 0.5-10% by weight. The compositions of the present invention may also optionally contain various other ingredients in addition to the ingredients already mentioned, examples of which include PH regulators, fragrances, dyes, optical brighteners, soil stains, etc. Examples include anti-adhesion agents, enzymes with cleaning effects, gelling control agents, freeze-thaw stabilizers, disinfectants, preservatives, and hydrotropes for detergents. The compositions of the present invention can generally be prepared at alkaline pH values, typically 8-11, preferably about 10-11. Alkalinizing agents such as sodium hydroxide and sodium carbonate can be used as regulators and buffers to adjust the pH to the desired value. Since the composition of the present invention is a liquid composition, it can be easily prepared by mixing the above-mentioned essential components and optional components in water.
