Abstract

ABSTRACT OF THE DISCLOSURE
A detergent composition comprising, as hardness ions complexing agent from 10% to 50% by weight of a water soluble salt of the citric acid; from 5% to 60% by weight of a water soluble salt of a fatty acid having a carbon atoms chain length from 6 to 24 C; and with a phosphor content from 0% to 2.5% by weight. To the said composition additives may be added, such as bleaching agents, optical brighteners, builders, alkalinazing agents, surface-active agents, fillers, and the like substances usually used in combination with detergent compositions.

Description

~A~EGRO~ND AND SU~MARY O~ ~HE INVEN~ION
============_====_=_====_===_========
~ he present invention refers to dried, ~inPlly divicLed detergent compositions, and more particularly to those powaery detergent compo3ition for use either by hand washing or in automatic washing machines, to launder or wa~h any type of fabric.
It i8 known that in order to be efficient to a satiefactory degree, a detergent composition mu3t be formed by at lea~t 5 (a) one or more surface active agents;
(b) one or more hardness ions removal agents, in oder to reduce the hardnees of the washing ~ater;
(¢) agents performing an alkalizing function;
(d) optic~l brighteners or chem~cal bleaching agents, in order to increase the whiteness of the fibers treated ~ith them.
~ he composition i8 genera~ly completed by additive3 to be present in sm~ll amounts, exerting ~ariou3 supporting a¢tion~, a8 ~ell as by inert fillers.
~he hardness ion~ seques.tering agents are commonly te~med "buildersn, and are ~urther responsible of variou3 desirable actions, exerted concurrentlg with their sequestering action, su¢h as for example, the peptizing action, the aispersing action, the anti-redeposition . . ~F

~i3~

acti~)n, r~he cla~ of substances which nowadays still perform this number o~ functions in the most satiefactory manner are the polypho~phates. ~o the polypho~phate3, however, it has been attributed a crucial action in promoting under particular conditions ~n uncontrolled propagatio~
of seaweedes within any surface ~aters (eutrophication factor), which leads to an adverse effect resulting from the alteration of the environmental conditions with consequent lo~ering of the oxygen content of the waters, due to ~ermentatio~ processes connected with the final stage o~ the seæweeds vit~l ¢ycle. ~he lowering of the oæygen content in the waters also adversely affects the vitPl cycle of the aquatic fauna.
In detergents, the substitution of polyphosphates is not an ~asy matter, since at present no other substaxce~
are avP~lable which are ~ureIy harmless from the vie~point of the environmental pollution and which pos~es~ the number of requirements ~hich are typic~l of a good builder.
D~E~__IPIIQN=O~ ~HE INVEN~ION

Quite surprisingly, it has bee~ found that it is pos9ible to substantiPlly reduce or even eliminate the polypho~phate content in the detergent composition3, without affeoting their ~ashing efficiency, by parti~lly ~38~9~

or totally substituting the polyphosphate~ in the detergent composition by a synergic combination of a ~oap and a soluble salt of the citric acid, hccording to a main aspect, the detergent compositions according to the present invention are characterized by a content of from 10% to 50% of a water soluble, pre~erably an alkzline-metal salt of the citric acid, a~d from 5~
to 60% of a water soluble, preferably an aIk~line-metal g~lt of natur~l or synthe~ic fatty acids, with a chain 7ength of from 6 to 24 atoms o~ carbon.
~ h; g kind o~ alkaline-metals fatty acias s~lts are commonly aesigned as "soaps", and 80 they will be ter~ed heins~ter.
It is essential that the two aforementioned compounds be simultaneously present in a detergent compo~ition, slnce ~either of them has the power of individually performing the action of builder, ~
required ~f a substantial reduction or a complete substitution of the polyphosphates is desired in the detergent compositio~
~ he sy~ergic action o~ the citrate and of the soap according to the invention i8 best shown when the ~sshing i~ done at high temperature~, where the diminished complexing po~er of the citrate is compensated by the de-hardening action of the soap 1~3~Z94 -., c2using the precipitation of the hardness ions present in the water, in the form of water-insoluble soaps.
~he lprecipitate thu~ ~ormed within the wa~hing solutio~
kas no eignificant tendency to ~tick to the w~shing machine or to the ~abrics.
~ he detergent compositions according to the present invention are furthermore characterized by a P content ranging between 0~ and 2.~% by weight in the final ~etergenu compositio , ~hich i8 a significantly reduced content if co~pared to the ordinary detergent~ used for t~e w&shing of fabrics, in which the P content ge~erP~ly has a much higher v~lue, in the range of 6 to 8% or more. ~he detergent ¢ompositions acoording to the pr2sent invention are therefore provided with a low eutrophication po~er, since the percentage o~ P is at a lo~ or at a zero vPlue. ~he citrate ~ich i8 present i ~hese compositions has a very low toxicity to~ard any se~weeds, invertebrates, fishes and ma~mal~. ~oreover it has a good biological degr2dabilty both in the w~ter ~a in the eart~ both in aerobic and anaerobic conaitions~
~he soPp too h~ a very low level of toxicity, ~n~ it c~n be wholly degraded into C02 and water i~ a very quick manner. ~herefore tke pollution power of the citrate and the soap results to be a particularly low one, wkile the dsgree of thsir ecologic consistency appears to be high.

.

~ Tarious surface-active agent~, ~Ikalizing agent~, supportin~ agents, atain removing agents, bleaching age~i~, optical brightener~, anti-redeposition agents, ~d ~ulert filler~ may be added to the composition according to the invention. ~he said agents are ~ell known in the art, ~nd will be not described ~urther.
1~ the composition according to the in~ention PlSo other sequesteri~g agents dif~erent from polyphosphates Pnd citrate mlght be used, in order to achieve some Pdditional performances of the detergents, i~ addition to tho~e ~lready quite satis~actory, which can be obtained wlth the detergents according to the inventio~.
Among the several sequestering agents ~hich cPn be u ed in combination in the composition according to the invention, the following organic acids, ~nd their salts, c~n be me~tioneas poly-carboxyl acids (other than citric acid); hydroxy-carboxyl acids; ~mino-carboxyl acids; carboxyl-~lkil-ethers; carboxyl -2nd phosphonic acids (with a m~ximum P ~alue of 2.5 in weight/c~lculated on the total weight of the composition); polyPnionic polymers.
~ g æ~ ex~ple of inorganic type agents de~elopping a comple~ing action, the compound~ corresponaing to the general formula:

(~at2/~1)X Me23-(sio23Y

113~Z9~L

may be mentioned, ~here ~at i8 a cation of the valénce n, exchangeable wQth calcium, x i8 a number from 0,7 to 1.5, Me i~ a member selected from the group co~ ting of aluminum and boron, and y is a ~umber from 0.8 to 6~
he compo~ition according to the in~ention c~n be prepared by any process which i8 suitable for the production of powdery detergents-~ he~e compositions are preferably prepared by aproces3 by ~hich the alkali metal ~alt of the citric acid, the soap ~nd the other components of the composition, which are stable under heat condition~
the form of aqueous pulpy batche3 are transformed by hot drying, preferably by hot atomization, into easy to handle powders, particularly into beads. ~o the thu~
obtai~ed powdered composition it is pos~ible to add some compone~ts, such as perborates, enzymes, perfumes nd the like components that cannot be subjected to the heat-drying proce~s.
~ he detergent compositions of the present in~ention do ~ot present the problems ~hich sre peculiar of the compositions with a lo~, or no conte~t of polyphosphates~
~ ne of these problems is con~tituted by the tendency to ~orm incrustations o~ the metallic parts of the ~ashing machine, and particularly on the tank or o~ the 1;138294 drum of the wa~hing machine~, or on the movable parts of the pump a~d o~ the discharge valve, on the pre~sure ~witch~ and especiPlly on the heati~g elements of the said machines. Particularly in the case of incrustation~
on the heating elements several adverse effects might occur. At ~irst, the thus formed incrustation tends to reduce the heat e~change between the heating elements a~d the ~ash~ng ~ater bath. ~his entrains the risk of an undue increa~e in the temperature of the heating element~, 80 that the heating elemerLts will probably ha~e a shorter average life. ~oreover, the washing cycle nill last for a longer time, if the switching from the one to the next ~tep of the cy¢le is controlled by a thermostat. As a re~ult, not only a waste of time will be produced, but also a ~aste of energy. In the case ~n w~ich the switching ~rom the one to the next step of the cycle is controlled by a timer, the result will be that a temperature lower than that requested w~ll be attæined in the concerned washing step. ~hi~
w;ll produce, according to statistical data, a lo~ering of the washing ef~iciency.
~ 11 the abo~e factors have an adverse influence on the average liie of the washing machine.
~ nother problem connected with detergents having a low, or even no content of polyphosphates, is that o~
the loading of the fabrics~ due to the deposition of 1~38Z94 sQlts on the washed fabrics. ~he fabrics might therefore becom greyish and rougher to the feel, and these factor~
are both of a fundamental importance as to the stand~rd of the ~a~hing.
~ he average life of the fabrics i8 al~o adversely a~fectea.
- ~inslly, tho problem which probably is the mo~t importa~t in detergent compositions with a lo~, or eve~ no conte~t of polyphosphates is the prob~em o~ the washing performance of the detergent.
~ he user~ are presently accustomed to employ high sta~dara detergents ~hich permit to obtain guite satisfactory results. ~his is also due to the sign~ficant contribution of polyphosphates ~hich occur in the presently used detergents.
~ he detergent~ of the present invention permit to keep at a good standard the effects of the ~ashing of fabrics, and to ~ep u~damaged, in the mec~n;cal wa~hing~ the compnnents of a wa~hing machine. By the u~e of the detergents according to the invention, the incrustations on the machins drum, on the tank surfaces ~n~ on the heating element~ are eliminated or reduced to a minimum, Pn~ also incrustations on ths washed fabric~
~re very reduced~ wi~h a good efficiency o~ deter~ency.
