Definitions

• ester salts e. g.
• R is a hydrocarbon radical or group having a secondary carbon atom
• R1 and R2 are aliphatic hydrocarbon radicals and the group R1-C-Rz contains from to 18 carbon atoms
• soap or soap solutions do not have.
• Soaps namely give rise to insoluble calcium and magnesium soaps in'hard water, which unnecessarily increase the soap consumption and causes undesired salt precipitation on the material to be washed.
• soaps in aqueous solution owing to hydrolysis give a more or less alkaline reaction which may have an unfavourable influence on thematerial to'be washed.
• acid medium soaps decompose with the formation of fatty acid which decreases or even nullifies the washing and purifying action of the soap whereas most kinds of soap in salt-containing water, such as sea water, sho'wn'o or practically no washing action.
• ester salt solutions for washing purposes the following drawbacks occur.
• the purpose of the invention is toimprove these properties which are present in insuflicient quantity, whereas the good properties, such as the resistance to hard water, to acids and if desired, the neutral reaction in aqueous solution,-
• ester salts with resinous products and particularly neutral or acid salts of resinous acids. This was not'at all -to "be expected, because the salts of the resinous acids behave in many respects as saltsof high molecular fatty acids.
• the quantity of resin and or resinate added is rather large, viz. 15-50% of the quantity of ester salt whereas preferably 30-40% are added.
• ester salt solutions are completely neutral, consequently have a pH value 7 it could be expected that this is no more the case in the presence of resinous acid salts as these hydrolyse in a certain degree in aqueous solution. It appears, however, that same does not give rise to difliculties in the present case.
• the resin and the resinous acid as well as the resinous salts dissolve in the ester salt solution without the lathering capacity etc. prejudicially influencing in any degree the saponification of the resin, and also the neutralization of the resinous acids which can be controlled such that this takes place incompletely and consequently a certain excess of resinous acids is present.
• On dilution with water it was surprisingly established that although a certain hydrolysis of the resinous salts takes place the pH value does not exceed '7.
• ester salts enriched according to the inlution are added in coarsely granulated condition.
• the addition can also take place at a lower temperature but the conversion then takes place less smoothly whereas a higher temperature gives rise to a too strong lather formation.
• other desired constituents such as glycerol, perfume, colouring agent or the detergent action promoting salts, such as phosphates, etc. can be added.
• Example II When using solid ester salts or ester salts separated from solution by lye washing agents, sham- Docs and the like can be prepared in dry condition.
• Solid ester salts can be kneaded with lye and the necessary quantity of molten resin or the like and left alone at room temperature or somewhat elevated temperature for some time in order to obtain a complete conversion.
• the rather pastelike water containing mass obtained can be dried by kneading with anhydrous pyrophosphate and by making of an excess of pyrophosphate be brought in such a form that the product can be pulverized and sieved.
• the pyrophosphate considerably contributes to the detergent action and cannot be regarded as an indifferent filler.
• ester salts separated by lye from a solution When ester salts separated by lye from a solution are started with, the lye remaining in these salts can be neutralized by kneading with the desired quantity of molten resin and if still an excess of lye should be present the non-combined, lye can be neutralized with acid pyrophosphate (anhydrous) whereupon by the addition of neutral pyrophosphate (anhydrous) the mass is converted into a dry product that is pulverized and vention with resinous salts consequently have not sievedonly maintained the original favourable properties but also obtained new ones making them more and better suitable as a detergent, shampoo, etc. than when no resin or resinous salts have been added.
• acid pyrophosphate anhydrous
• resinous salts consequently have not sievedonly maintained the original favourable properties but also obtained new ones making them more and better suitable as a detergent, shampoo, etc. than when no resin or resinous salts have been added.
• resinous salts can take place as well with ester salts as such as in solution.
• Example I When making a solution one can proceed as follows: An ester salt solution with a content of 20% of active substance is heated to 80-90 C. 70
• rosin product used in the claims 0 is intended to include resin or the resin products referred to in the specification, rosins, derivatives of resins and their water-soluble salts, unless otherwise limited.
• rosin product comprising between 15% and 50% of the quantity of the sulfate ester salt.
• a process as defined by claim 1 characterized in that the product has a pH of approximatel 6 to 7.
• a process for the preparation of strongly lathering and purifying washing agents adapted for use in hard water and sea water comprising mixing in dry condition a water soluble salt of a sulfate ester containing a hydrocarbon group having a secondary carbon atom, an unsaponified rosin product, and sufficient alkali to efiect neutralization and saponifica-tion of the rosin product, and kneading the mixture to eifect saponification of the rosin product, said rosin product being present in the mixture to the extent of from 15% to 50% of the quantity of the sulfate ester salt therein.
• a process as defined by claim 5 characterized in that a paste-like mixture is obtained, and drying the paste-like mixture.
• a process as defined by claim 5 characterized in that a paste-like mixture is obtained, drying the paste-like mixture, and mixing with the dry material an anhydrous alkali metal pyrophosphate.
• a strongly lathering and purifying washing agent for use in hard water and sea, water comprising a composition containing a water soluble salt of a sulfate ester containing a hydrocarbon group having a secondary carbon atom and a water soluble salt of a rosin product, the salt of the rosin product comprising between 15% and 50% of the salt of the sulfate ester.
