These monoesters replace in the detergent previously used phosphates which caused eutrofication and endangered the ecology.
10 Claims, N0 Drawings DETERGENT BACKGROUND OF THE INVENTION The present invention relates to washing, dishwashing and cleaning detergent compositions in the form of powders, granules, pastes, or liquids, in which the phosphates previously used in such detergents are completely or partly replaced by chemicals which are more suitable from the eutrophic point of view. The invention discloses the replacement of the phosphates which are undesirable from the eutrophic point in view by aliphatic carboxylic acids and/or their salts, such as lactic acid, acetic acid, tartaric acid and citric acid, or by aromatic carboxylic acids such as, e.g., benzoic acid, phthalic acid and tri-, tetra-, pentaand hexabenzenecarboxylic acids and/or their salts.
SUMMARY OF THE INVENTION The present invention concerns the use of the salts of particularly the fruit acids as these have proved most suitable as substitutes for phosphates. The reason herefor is that they decompose easily biologically, forming few toxic substances, and they do not pollute lakes and rivers with phosphor or nitrogen.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT To increase the washing efficiency of these carboxylic acids it has proved suitable to let the carboxylic acids or part of the carboxylic acids incorporated in the detergent compositions react with lower alcohols to form monoesters. The a'lakaline salts of acid esters exhibit both lipophilic properties (alkyl groups) and hyd'rophilic properties (carbonyl group, COONa). Since the dirt particles generally are embedded in fat these monoesters have proved suitable for use in a system consisting of mixture of fat and water wherein the alkyl group imparts the lipophilic properties to the molecule whereas the esterified COOH-groups impart the typical acid character to the molecule, i.e., its capability of forming complex heavy metal ions. Owing to the strengthened lipophilic property the dispersing and emulsifying properties of such compounds are hightened. The reason for the restriction to monoesters in this connection is that the higher esters are much less soluble and for this reason do not provide the same efficiency in detergents. In addition, the biological decomposibility of the compound must be taken into consideration. Furthermore, the biological oxygen consumption, the so called, BO -values, is lower in the case of monoesters than in the case of higher esters.
.The esters are generally produced by esterifying the anhydrous acid with its respective alcohol and with a suitable catalyst or while using other suitable methods.
In the formulae given below X represents Na, K, or
NH, and R the alcohol rest having one to eight carbon atoms.
Examples of monoesters: XO CCH--CHCO -R 1. Sodium ethylene dicarboxylic acid monoethylester NaO- CCH=CH-CO CH H 2. Potassium ethylene dicarboxylic acid monoethyl ester KO CCl-l=CH-CO CH V 3. Potassium ethylene dicarboxylic acid monobutyl ester XO C-CH -CI-I(OI-I)CO R 4. Sodium oxyethane dicarboxylic acid monoethyl Na-O CCH CH(OH)-CO CH 5. Sodium oxyethane dicarboxylic acid monoisoamyl ester 6. Ammonium ethane dicarboxylic acid monopropyl ester NH4-O2C CH2CH2CO2C3H7 7. Potassium ethane dicarboxylic acid monoethyl ester KO2C-CH2CH2 CO2C2H5 8. Sodium dioxi-succinic acid monomethyl ester Na-O C-CH(OH)CH(OH)CO -CH 9. Potassium dioxy-succinic acid monosecbutylester K-O CCH(OI-I)CH(Ol-l- )CO CH(CH )C I-I 10. Sodium l.2.3.-propene tricarboxylic acid monoethyl ester NaO CCH =C(CO I-I)CH- 2 2 2 s 11. Ammonium tricarballylacid monohexylic ester l2. Sodium-Z-hydroxypropane tricarboxylic acid monoisoamylester NaO C-Cl-I C(Ol-l)-CO HCH- 2 2 5 11 l3. Potassium-2-hydroxypropane tricarboxylic acid monopropylester KO CCH -C(OH)CO HCI-I CO C H Naturally, the invention is not limited to the monoesters enumerated above but also other carboxylic acid monoesters which are harmless from a toxicological point of view may be used. One condition is, of course, that they are acceptable from a water-preservation point of view. In addition, they must give satisfactory washing results. Experiments have shown that to strenester gthen the efficiency of these esters it is advantageous to add polyvalent higher alcohols in amounts up to 25 percent, preferably between 0.5 and 8 percent, calculated on the amount of the above esters.
The anionic, amphote ric or nonionic surfactants which may be present in the detergents in accordance with the invention contain in their molecule at least one hydrophobic group having eight to 30 carbon atoms and a group making them water-soluble, this group being of anionic or nonionic character. Soaps, sulphonates, and sulphates are of importance as anionic active detergents. Also phosphate surfactants could be used. The sulphonates may be alkylaryl sulphonates, alkyl sulphonates, alkene sulphonates, oxyalkene sulphonates and oxyalkane sulphonates. Also sulphonated esters may be used. The sulphates may be, e.g., alkyl sulphate, fatty alcohol ether sulphate, sulphated amides of fatty acids, sulphated monoglycerides, sulphating products of ethoxylated and/or propoxylated fatty alcohols, alkyl phenols, fatty acid amides, and so on. Sulphonates of fatty acid esters of oxethane sulphonic acid and dioxypropane sulphonic acid, fatty alcoholic esters of lower aliphatic and aromatic thiomonoand dicarboxylic acids as well as condensation products of fatty acids with aminoethane sulphonic acids are useable. Synthetic, capillary-active carboxylates as well as condensation products of fatty acids with amino-carboxylic acids or with protein hydrolysates as also phosphate esters of fatty alcohols and fatty acids may be used.
As nonionic surfactants may be used, e.g., alkyl phenols, fatty alcohols, alkyl amines, fatty acids and fatty acid alkylol amides, fatty amides polyglycol esters, phosphate esters of ethoxylated fatty alcohols, block polymerisates of ethylene oxide and propylene oxide, etc.
Also amphoteric surfactants may be used, such as imidazoline derivates of fatty acids, carboxybetaines, compounds with the phosphoric acid groups in the acid rest, or with sulphonic or sulphuric acid groups.
Foam stabilizers of foam inhibitors as well as corrosion inhibitors may be included and so may dirtcarrying substances, optical brighteners, perfumes, bactericides, enzymes, dyes, and water. Also different types of'bleaching agents containing oxygen or chlorine and activators and stabilizers belonging thereto may be included.
In summary, all surfactants and aids used in connection with detergents and cleaning agents may be combined in accordance with the principle of the present invention and the enumeration given above is not to be considered as any restriction whatsoever.
