Definitions
- This invention relates to a laundering agent, containing detergent, builders, a combination of polyphosphate with zeolite and, if desired, further usual additives.
- bleaching agents particularly perborate.
- optical brighteners are added and furthermore for example enzymes, carboxy methyl cellulose, EDTA etc.
- a problem occuring with the laundering agents having a combination of phosphate with zeolite is the incrustation which is considerably higher than with phosphate only. This incrustation shows from the ash content after a number of test launderings. Also the above article from Tenside Detergents relates to this problem and it appears therefrom that for instance a combination of 30% zeolite A with 5% NTA gives a low ash content, but on the other hand does not possess a very good primary laundering power. Without further additives mixtures of polyphosphate and zeolite A lead to a higher ash content than laundering agents containing polyphosphate only. A combination which is particularly good as regards ash content is 20% polyphosphate plus 10% NTA, a system, of which also the primary laundering activity appears to be reasonably good.
- NTA is a relatively expensive component which moreover should not be used in unlimited quantities. As appears from the above mentioned article from Tenside Detergents, relatively large amounts of NTA would be necessary to arrive at a good result. Also a ternary system of phosphate, zeolite and NTA is not ideal and complicates the system.
- this invention provides a laundering agent, containing active detergent, builders, a combination of polyphosphate with zeolite and, if desired, further usual additives, which is characterized by the fact that it also contains at least 0.3% and no more than 10% of a compound of the formula RO-(C 2 H 4 O) x -CH 2 COOM or R-CO-NH-(C 2 H 4 O) x -CH 2 COOM., wherein R is an aliphatic or alkyl aromatic hydrocarbon residue containing at least 8 carbon atoms, x is a number having an average value of 0.5-20, and M is hydrogen or a cation acceptable in laundering agents.
- the abovementioned lower limit of 0.3% is based on a replacement of the usual amount of polyphosphate (30 to 40%) with about the half amounts of polyphosphate plus zeolite (and if desired NTA) . In the case of an amount of less than 0.3% of the present ether carboxylic acids the effect is then too small.
- the upper limit given is only a economical one.
- the polyether carboxylic acid itself is a detergent and in principle could also constitute entirely or partially the detergent component. However, at present, this is not (yet) economically feasible for mass production, for the polyether carboxylic acids are considerably more expensive than for instance the so-called ABS-products (alkylbenzene sulphonates). This is the reason why an amount of more than 10% ethercarboxylic acid economically is senseless and usually and preferably no more than 5% thereof is used and even more preferably even less.
- the present laundering agent is of the usual, strongly basic kind.
- active detergents it may contain all usual anionic, non-ionic and zwitterionic surfactants. Usually a number of surfactants is used in combination.
- the total content of active detergents usually is 7-16% of a laundering powder.
- the combination of polyphosphate and zeolite usually constitutes 25-45% by weight of the laundering agent.
- sodium perborate as a bleaching agent is also used in an amount of generally 15-25%.
- any other bleaching agent can be used, such a trichloro cyanuric acid.
- an optical brightener is used, usually in a small amount of no more than 0.5%.
- a further usual ingredient is carboxymethyl cellulose which is usually used in an amount of 0.5-5%.
- an enzyme particularly a proteolytic enzyme, may be present in amountss upto 3%.
- alkaline builder is present, usually sodium carbonate and sodium silicate and the like.
- the remainder of the laundering agent can be constituted by so-called neutral builders, i.e. sodium and magnesium sulphates.Furthermore, additional EDTA as a complexing agent can be present in a small amount (upto 1%). In such a laundering agent the present ethercarboxylate is now incorporated in an amount in the abovementioned range.
- ethercarboxylic acids in as far as they are derived from alcohols,are commercially available many years already and they have been described in numerous publications, which also applies to their preparation.
- the ethoxylation may be carried out both with a basic catalyst (NaOH), and with an acidic catalyst (e.g SbCl S ).
- a basic catalyst NaOH
- an acidic catalyst e.g SbCl S
- ethoxylation products are formed according to a broad distribution and in the last case a much narrower distribution of ethoxylation products is formed.
- the ethercarboxylic acids derived therefrom show the same distribution pattern. For the i present purpose both kinds are useful.
- NaTPP sodium tripolyphosphate
- a laundering powder intended for laundering at 90°C was composed as follows:
- the polyether carboxylic acid can also be incorporated as the free acid in the alkaline laundering agent, whereby the salt is formed in situ without the relatively small added amount influencing the pH to an important degree.
- the polyether carboxylic acid may be used in the form of a crude reaction mixture, as is obtained during its preparation after treatment with a small amount of water and acid, as disclosed in Dutch patent application 8103860.
- the optimum nature of the ethercarboxylic acid (or salt thereof) somewhat depends on the other ingredients of the laundering agent, particularly the active detergent, and in this respect the known variations in the hydrphobic residue and the average number of oxyethylene units are possible.
- the product used in the above experiment will be satisfactory in a great number of cases or will even constitute the optimum product.
