Definitions
- the invention relates to alkaline cleansing agents and, more particularly, to cleansing agents containing additives which are stable against hydrolysis and which effectively prevent the deposit of calcium compounds due to the use of hard water.
- alkaline cleansing agents frequently contain not only the customary components, i.e., caustic alkalis, alkali carbonates, -silicates, -phosphates and/or -borates, detergents and foam suppressants, but also materials which are to serve to prevent the formation of calcium deposits from the hardness-formers in the water.
- Polymeric phosphates often are incorporated in alkaline cleansing agents to prevent the precipitation of the hardness-formers in the water.
- polyphosphates are not resistant to hydrolysis in the cleansing solutions and decompose into orthoand pyrophosphates within a comparatively short period of time. Losses of polymeric phosphates by hydrolysis frequently even occur during storage, especially when the cleansing agents are highly alkaline.
- R is a straight-chain or branched alkyl having 1 to 5 carbon atoms; plus (b) An aminopolyphosphonic acid of Formula 2 Rr-CXY NCXYR:
- Rr-CXY wherein X and Y individually represent either hydrogen or an alkyl having 1 to 4 carbon atoms: R, and R indrvidually may be a --PO H group or a group or radical of 'Formula 3:
- Examples for group (a) are hydroxyethane-, hydroxypropane-, hydroxybutane-, hydroxypentaneand hydroxyhexane-1,1-diphosphonic acids.
- aminotri-(l-ethylphosphonic acid), ethylenediaminotetra-(l-ethylphosphonic acid), ethylenediaminotetra-(l-ethylphosphonic acid), aminotri-(l-propylphosphonic acid), and aminotri-(isopropylphosphonic acid) may be named, and preferably aminopolyphosphonic acids of Formula 4:
- R (as in the preceding formulae) is a PO I-l group, R, and R may individualy be a PO H group or a radical having Formula 5:
- CHr-Ril -C Hg-N CHz-Ra R again having the same connotation as before; such as aminotri-(methylphosphonic acid), ethylenediaminotetra- (methylphosphonic acid) and diethylenetriaminopentamethylphosphonic acid).
- the concentrations in which the mixtures of hydroxyalkane-l,l-diphosphonic acid with aminopolyphosphonic acid are introduced in to the cleansing agents can vary within a wide range and lay between 0.5 and by weight, calculated on the content of alkali.
- the addition to the alkaline cleansing agent should be calculated in such a manner that the concentration of the mixture of (a) and (b) in the aqueous solution of said alkaline cleansing is substantially 0.05l g./l. These values relate to the pure free acids.
- Both the component acids can be added to the alkaline cleansing agent as free acid or in the form of the r water-soluble salts, preferably their alkali metal-, ammoniumor alkanolamine salts. Preferred are the sodium and potassium salts.
- the hydroxyalkane-l,l-diphosphonic acid and the aminopolyphosphonic acid or their salts, respectively, may be incorporated in liquid or solid cleansing agents.
- the manner of incorporation is not critical. Solids can be added to solid cleansing agents during the mixing step; they may be sprayed thereon in concentrated solutions; or they may be slurried and added to liquid material prior to spraydrying.
- the phosphonic acids named and their mixtures are readily soluble and completely resistant to hydrolysis and therefore are especially suited for addition to highly alkaline cleansers and to alkaline concentrates, but also to acid concentrates to which alkali later is added to produce an alkaline cleansing agent.
- the alkaline cleansing agents contain, aside from the mixture of hydroxyalkane-l,l-diphosphonic acid and aminopolyphosphonic, the commonly used alkali carriers in a concentration of 5-95 weight percent, such as caustic alkali, preferably NaOH, or KOH, alkali carbonates, preferably soda, alkali silicates, alkali phosphates, alkali borates, singly or in mixture, and, if desired or required, detergents, antifoams, bleaching agents, and disinfectants, in concentrations of 0.05 to weight percent.
- the amount of alkali in the alkaline cleansing agents should be calculated in such a manner that the concentration of the alkaline carriers in the aqueous solution of said alkaline cleansing agents is substantially 1-50 g./1.
- the cleansing agents according to the invention can be used in all cleansing and washing processes wherein a coating or calcium deposit and precipitation (stone formation) is apt to occur due to the hardness of the water employed, for instance in all kinds of washing and rinsing machines.
- the cleansers according to the invention containing a mixture of hydroxyalkane-l,l-diphosphonic acid with aminopolyphosphonic acid faultlessly prevent a formation of coating or stone even with the use of very hard water, e.g., of a hardness above 30.
- the effect is far better than with cleansers which contain the components (a) or (b) singly and also is superior to a purely additive effect of the single substances.
- the stone formation of coating deposit does not increase.
- the hardness degrees in this specification are so-calicd d.H., i.e., degrees of German hardness, a German industrial standard, wherein ld.H. equals 10 mg. (:10 per liter.
- Temperatures are in degrees centigrade; percentages are percent by weight; solutions are aqueous; unless otherwise specified.
- EXAMPLE 1 Stainless steel sheets were immersed for 2 minute: in 1% NaOH solution at 50, then rin ed for 2 minute in water at room temperature, and dried for 2-3 mmute.-. in a current of hot air. This cycle was repeated 500 times. Thereafter, the deposit (or coating) formed on the su faces of the sheets was determined by weighing. Tht NaOH solution was prepared with water of 36 hardness. and increasing amounts of hydroxyethane-l,l-diphosphonic acid, aminotri-(methylphosphonic acid) and mixtures of these two acids in weight proportions of 3: l, 1:], and 1:3, added. The rinse water also had a 36 hardness. The coating weights are listed as g./m.'- in Table l.
