Definitions

  • the present invention relates to fabric softening agents, more particularly a ine compounds containing one or more long-chain alkyl or al enyl groups.
  • Fabric softeners are commonly used to render textiles soft to the touch after a laundry treatment and are incorporated into commercial laundry products such as detergents, rinsing agents, and laundry drying agents.
  • Representative commercially available fabric softeners include dimethyl distearyl ammonium chloride and 1-methyl-2-tal1owalkyl-3-tal1owamido-ethyl imidazoliniurn methosulphate.
  • These known fabric softeners display a serious drawback in that they have no or only very slow biodegradability, whereas their primarily domestic wide-scale use is attended with large amounts of them ending up, via the sewerage system, in the city waste water and complicating its purification.
  • Canadian Patent No. 1 164470 discloses the use of a wide range of protonated amines as additives for a number of formulations, including fabric softener formulations. No indication is given as to whether any of the disclosed compounds could themselves exhibit softening activity.
  • EP A 281 975 a wide range of amines is disclosed which act as a softening-activity imparting ingredient if formulated together with a carboxylic acid having of from 1 to 24 carbon atoms. No indication is given as to whether any of the disclosed compounds would be biodegradable.
  • EP 293953 pertains to fabric softeners comprising quaternary ammonium fabric softeners containing a single ester group.
  • the disclosed quaternary ammonium compounds are stated to be biodegradable, but further improvement in this respect is desired.
  • the disclosure does not pertain to the problem of formulating effective, biodegradable softeners based on amines.
  • DE-PS-2728841 discloses fabric softeners based on quaternary ammonium compounds containing two ester moieties. The disclosure does not pertain to biodegradability, nor does it address the aforementioned problem of formulating effective softeners based on amine compounds.
  • the present invention provides a biodegradable fabric softening agent which comprises as essential constituent an ester group-containing cationic nitrogen compound of the formula 1:
  • R represents an alkyl or alkenyl group having 7-22 carbon atoms
  • R' represents an alkyl or alkenyl group having 7-21 carbon lb atoms
  • R" and R 1 may be the same or different and represent an alkyl or hydroxyalkyl group having 1-6 carbon atoms, p equals 0 or 1, and Q X" represents an anion.
  • the amine is required to be protonated to provide a favourable softening action. This is generally effected by employing the amine in fabric softening compositions having a low enough pH to have the amine 5 present in the rinse in the protonated form. This means that the amine is present in softener compositions in conjunction with an acid. Hence the counterion X" is an acid radical.
  • an effective softener is 0 provided by the instant select group of protonated amines without additional steps being required.
  • additional steps such as described in EP 417987 referred to above, will negatively affect the performance of the instant softening agents.
  • the steps according to EP 417987 are applied to the amines according to the present invention, an even better softening performance is attained as compared with Armeen ® M2HT. Rather, it is stressed that no additional steps being required shows the unexpected and unique performance of the instant selected amines.
  • the cationic nitrogen compound is of the formula 2:
  • R' wherein R represents an alkyl or alkenyl group having 8-22 carbon atoms and R', R", R"', and X- may have the above-disclosed meanings.
  • the cationic nitrogen compound is of the formula 3:
  • R and R' represent an alkyl or alkenyl group having 8-22 carbon atoms and R", R'", and X ⁇ may have the above-disclosed meanings.
  • amine compounds of the latter formula display a further advantage in that they are more readily biodegradable than Armeen ® M2HT disclosed in EP-A-417 987, particularly if R" and R" 1 are methyl and R and R' are C15/17 saturated hydrocarbon.
  • R and R' preferably represent essentially linear alkyl or alkenyl groups that may be derived from fatty acids or mixtures thereof.
  • alk(en)yl groups usually derived from natural fatty acid mixtures, such as tallow alkyl, hydrogenated tallow alkyl (H-tallow alkyl), and coco alkyl, that are made use of.
  • These groups are also preferred for use in the biodegradable fabric softeners according to the present invention on account of their easy availability at a low price.
  • the proton in the protonated amine may be hydrogen derived from the acid fabric softener medium.
  • the counterion X" is an acid radical, preferably of an organic carboxylic acid and more particularly of a hydroxycarboxylic acid. Most suitable are citric acid, malic acid, and glycolic acid. Of course, acids are well-known to the person of ordinary skill in the art, and need no further elucidation here. To affect protonation of the instant amines the acid may simply be mixed with an equivalent amount of amine. Complicated melting processes, such as disclosed in EP-A-281975, are not required.
  • the present cationic nitrogen compounds can be prepared in the manner known for the preparation of analogous compounds.
  • preparation of a representative cationic nitrogen compound according to the present invention is described in detail, and the remaining biodegradable fabric softening agents according to the present invention are directly accessible to the skilled man through adaptation of the starting substances concerned.
  • the manner in which the present biodegradable fabric softening agent is applied is the same as for the conventional, now commercially available fabric softeners.
  • the usual possibilities in this respect are either using the agent in admixture with detergent, or adding it separately, i.e. during the rinse-cycle as a rinsing agent or else in the dryer.
  • the instant softening agents are particularly advantageous as rinse-cycle added softeners.
  • the fabric softening action envisaged and actualised here is at least the same as for the conventional quaternary ammonium fabric softeners.
  • a portion of the fabric softener will end up in the waste water, where, because of the present invention, there will be less harm to the environment as a result of accelerated biodegradability.
  • the present biodegradable fabric softening agents were tested for their fabric softening performance and found to be comparable with dimethyl dihardened tallow ammonium chloride, distearyl ammonium chloride and l-methyl-2-tallowalkyl-3-tallowamido-ethyl imidazoliniu methosulphate.
  • test towels treated with the fabric softeners in question were line dried for 24 hours and then cut up into STRIPS of 10 x 20 cm*--.
  • a test panel evaluated the softening action as compared with that of the standard test detergents (IEC), whereupon the observational data was statistically processed in accordance with DIN standard 10954.
  • the present quaternary ammonium compounds were tested for biodegradability in accordance with the EEC/OECD guidelines OECD 301D "closed bottle test".
  • OECD 301D closed bottle test
  • a test compound is added to an aqueous solution of mineral salts and exposed for 28 days under aerobic conditions to a relatively small number of micro-organisms.
  • the formal test regulations were departed from on the following minor issues:
  • the inoculum was taken from an apparatus containing activated sludge preconditioned in accordance with proposed amendments to the EEC guidelines; ammonium chloride was not included in the medium to avoid nitrification;
  • the dissolved oxygen concentrations were determined electrochemically using an oxygen electrode (WTW Trioxmatic EO 200) and an oxygen gauge (WTW 0X1 530), and biodegradability was calculated as the ratio of biological oxygen demand (BOD) to theoretical oxygen demand (ThOD) : BOD/ThOD.
  • the conversion was monitored with the aid of either TLC or GC. After 6 hours, the composition of the product was as follows: 90.4% of diester amine, 4.9% of onoester amine, and 4.7% of free fatty acid.
  • the diesteramine was converted into the corresponding cationic nitrogen compound by protonation with citric acid monohydrate. Said protonation was carried through by adding to water, with stirring, 5 wt% of the diester amine and the equivalent amount of 1.66 wt% of citric acid monohydrate. In the case of the embodiment using excess acid 5 wt% of the diester amine and 5 wt% of citric acid monohydrate were ' added to water. The addition of the diester amine to water resulted in a stable dispersion.
  • the ono ⁇ steramine was converted into the corresponding cationic nitrogen compound by protonation with citric acid monohydrate. Said protonation was carried through by adding to water, with stirring, 5 wt% of the monoester amine and the equivalent amount of 2.8 wt% of citric acid monohydrate. In the case of the embodiment using excess acid 5 wt% of the monoester amine and 5 wt% of citric acid monohydrate were added to water. The addition of the monoester amine to water resulted in a clear solution.
  • Biodegradability is indicated by means of the percentage of degradation after 28 days. A compound is considered to be “readily biodegradable” if biodegradation is ⁇ 60%. Further improved biodegradability is shown if the percentage is over 70%, which may be regarded as ultimate biodegradation. The margin of error in these tests usually is 10%.
  • R and R 1 are saturated C15/17 hydrocarbon
  • R" is a hardened tal low al kyl radical
  • Citri c acid equiv. amt. ++ 78
  • Citric acid excess amt. +++
  • Citric acid equiv. amt. 63 B Citric acid, excess amt.
  • Citric acid equiv. amt. 59 C Citric acid, excess amt.
  • protonated amines according to the present invention are favourable biodegradable softeners. It is also apparent that protonated amine formulations not in accordance with the present invention may make viable softeners but will not exhibit said surprising softening effect without additional steps.
