Definitions

washing apparatus has been directed toward further increasing the intensity of the liquor motion as well as the water volume cycled per minute, and in this way to further improve the mechanical cleansing effect.
conventional washing agents such as higher molecular weight sulfates or sulfonates, caused too much foam.
nonionic surface-active agents such as ethylene oxide addition products to alkylphenols or polypropylene glycols, have been preferred. These products, as well, were found to have a relatively high foaming tendency in the ranges of concentration required for satisfactory wetting and cleansing effect when used in the modern dish washing machines.
alkylene oxide addition products are not biologically decomposed to a sufficient extent. For this reason, they often play a part in the formation of foam on sluices, dams and overflows. Furthermore, such products often exhibit, even in small amounts of only a few mg./ 1., a distinct toxicity toward fish and other water organisms.
Patented Dec. 21, 1971 thus, they can represent a considerable and undesired burden on waste waters and their treatment.
washing and cleansing compositions are characterized by a content of:
An object of the invention is the obtention of highly effective and extremely low-foaming dish and general purpose detergent combinations for dish washers which do not cause any waste water problems due to their biological harmlessness.
a further object is the obtention of low-foaming rinsing and washing compositions adapted for dish washers consisting essentially of (A) from 70% to 98% by weight of water-soluble polyvinyl alcohols having a molecular weight of between 1000 and 4000, and (B) from 2% to 30% by weight of foam inhibiting compounds selected from the group consisting of compounds of the formula wherein R is a member having from 8 to 22 carbon atoms selected from the group consisting of alkyl, alkenyl, alkadienyl, hydroxyalkenyl and alkylcycloalkyl; R is an alkyl having from l8 to 22 carbon atoms; R; and R are members selected from the group consisting of hydrogen and lower alkyl; and Me is an alkali metal.
Another object of the invention is the obtention of aqueous solutions of the above low-foaming rinsing and washing compositions.
a yet further object of the invention is the development of a method of washing and rinsing solid articles which comprises forcefully contacting said solid articles with water containing from 0.01 to 0.5 gram per liter of the above low-foaming rinsing and washing compositions.
the present invention relates to lowfoaming rinsing and washing compositions adapted for dish washers based on polyvinylalcohol and foam-suppressing agents, which is distinguished by a good compatibility with waste waters and harmlessness against fish and other water organisms.
compositions are characterized by a content of (A) from 70% to 98% by weight of watersoluble polyvinylalcohols having a molecular weight of between 1000 and 4000, and (B) from 2% to 30% by weight of foam-inhibiting compounds selected from the group consisting of aliphatic alcohols, aliphatic carboxylic acids and alkali metal salts thereof, aliphatic carboxylic acid amides and aliphatic amines, said compounds having at least one aliphatic or aliphatic-cycloaliphatic radical with from 8 to 22 carbon atoms.
the claimed combination is extraordinarily low foaming even under extreme application conditions, both in household dish washers as well as in commercial dish washers.
the compositions of the invention possess an excellent wetting effect with respect to hard surfaces such as porcelain. synthetics or metals.
the combinations of the invention are particularly suitable as low-foaming, clear rinsing agents for dishes and silverware of all kinds, possibly with a preceding alkaline pre-washing phase, as well as for washing and clear rinsing of alkaline-sensitive glassware such as drinking glasses and other glassware.
An exceptional run off of the rinsing water is obtained, resulting in shining, spot-free articles.
the biological decomposition of the foam inhibitors of type B is relatively good. Due to the fact that in practice the portion of component B of the mix- I ture is always relatively small, no disturbing burdens on the waste water are to be anticipated, even in cases where the biological decomposability is less due to the use of branched chain radicals or the like.
the water-soluble polyvinylalcohols having a molecular weight of between 1000 and 4000 used as component A are known products and are used in the trade. They can be obtained, for instance, by means of hydrolysis of polyvinyl acetates of the corresponding degree of polymerization. Within the framework of this invention such watersoluble polyvinylalcohols are preferred which have a hydrolysis degree of 85% to 90% and have molecular weights of approximately 1000 to 3000.
compounds of group B are, above all, saturated or unsaturated fatty alcohols with 10 to 18 carbon atoms.
Particularly useful are compounds of the formula R-OH wherein R is a member having 8 to 22 carbon atoms selected from the group consisting of alkyl, alkenyl, alkadienyl, hydroxyalkenyl and alkylcycloalkyl.
R is a member having 8 to 22 carbon atoms selected from the group consisting of alkyl, alkenyl, alkadienyl, hydroxyalkenyl and alkylcycloalkyl.
Employed in practice are above all mixtures of such fatty alcohols as are obtained from natural fats and oils.
suitable fatty alcohols are dodecyl alcohol, hexadecyl alcohol, tallow alcohol mixtures of the chain length C to C coconut fatty alcohol mixtures of the chain length C to C and the like.
alcohols of a corresponding chain length can be employed as well which are obtained through synthetic methods, as, or example, according to the Ziegler method.
branched chain alcohols with up to 22 carbon atoms can be utilized as can be obtained through the oxo-synthesis or through the Guerbet reaction.
RCOOH and R'COOMe are fatty acids with a chain length of C to C
Particularly useful are compounds of the formula RCOOH and R'COOMe wherein R is a member having 8 to 2.. carbon atoms selected from the group consisting of alkyl, alkenyl, alkadienyl, hydroxalkenyl and alkylcycloalkyl; R is an alkyl having from 18 to 22 carbon atoms; and Me is an alkali metal.
fatty acids or fatty acid mixtures are preferred which have been obtained from natural fats and oils as, for instance, from fatty acid mixtures obtained from coconut fats of the chain length C to C or C to C oleic acid, behenic acid as well as preliminary faction fatty acids containing larger amounts of fatty acids of the chain length C to C Fatty acids containing more than 18 carbon atoms can be employed in form of their alkali metal salts as well.
fatty acid amides or fatty amines of the chain length C to C come also into consideration as foam inhibitors such as, for instance, tallow fatty acid-N,N- diethylamide, dodecylamine, the tallow amine mixture prepared from tallow fatty acids of the chain length C to C13, Ctc.
the individual components in the low-foaming rinsing agents of the invention amount to approximately to 98% by weight of component A and 2% to 30% by weight of component B. In practice it was, in particular, that mixtures from to by weight of component A and 5% to 15% by weight of component B are particularly suitable.
concentrations of approximately 0.05 to 0.5 gm./liter, preferably 0.1 to 0.4 gm./ liter in the cleaning fluid are required.
concentrations are employed as rinsing agent subsequent to an alkaline washing phase, approximately 0.01 to 0.25 gm./liter, preferably 0.02 to 0.1 gm./liter are used. To a certain degree the concentrations are dependent upon the hardness of the water and the type of dishes. When washing or rinsing, utilizing hard and salty waters, or with plastic dishes, greater amounts of the rinsing agents are required.
compositions of the invention are prepared in the form of aqueous concentrates with a content of approximately 10% to 30% by weight of mixtures of components A and B.
the concentrates can be adjusted in such way that they possess a good temperature stability and do not tend to precipitate or separate into layers.
the concentrates are added into the washing and rinsing solution in the dish washing machines by means of an automatic dosing device as is common for such purposes.
the foam apparatus was constructed in similar manner as a modern dishwasher operating according to the jet spray system.
a pump By means of a pump about liters of water per minute were rotated and sprayed into the metering chamber by means of a rotating spray-arm provided with nozzles.
Foam heads from 0 to 280 mm. may be measured in reproducible manner, whereas larger foam volumes can no longer be measured accurately, and, therefore, they are indicated in the table as 280.
the liquor temperature during the tests was 50 C.
the hardness of the water used was 16 dH and the duration of the foam test lasted 5 minutes.
the reading of the foam height was done immediately after the machine came to a standstill and 30 seconds after the machine had come to a stop.
a liquid rinsing agent suitable for commercial dish washers had the following composition:
Percent Polyvinylalcohol (viscosity of a 4% solution at 20 C., 3 cp., hydrolysis degree: 88%) 20.0 Dodecyl alcohol 0.7 Water 79.3
the product developed practically no foam.
the above aqueous concentrate was dosed into the rinsing water in concentrations of 0.4 to 0.6 gm./liter. Spot-free, shining dishes were obtained.
EXAMPLE 7 An extremely low-foaming detergent for household dish washers had the following composition:
Percent Polyvinylalcohol (viscosity of a 4% solution at 20 C., cp., hydrolysis degree: 86%) 10.0 Sodium behenate 0.6
Low-foaming rinsing and washing compositions adapted for dish washers consisting essentially of (A) from 70% to 98% by weight of water-soluble polyvinyl alcohols obtained by hydrolysis of polyvinyl acetates, having a hydrolysis degree of between 85% and 90% and having a molecular weight of between 1000 and 4000, and (B) from 2% to 30% by weight of foaminhibiting compounds selected from the group consisting of compounds of the formula wherein R is a member having from 8 to 22 carbon atoms selected from the group consisting of alkyl, alkenyl, alkadienyl, hydroxyalkenyl and alkylcycloalkyl; R is an alkyl having from 18 to 22 carbon atoms; R and R are members selected from the group consisting of hydrogen and lower alkyl; and Me is an alkali metal.
component B is an acid compound selected from the group consisting of fatty acids having from 8 to 22 carbon atoms and alkali metal salts of fatty acids having from 18 to 22 carbon atoms.
