    Abstract: A process for reducing the residual content of free alkylating agent in aqueous solutions of cationic surfactants comprising aftertreating the solutions with at least one of the following amine compounds:a) ammonia;b) tertiary amine corresponding to the general formula (I) ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 independently of one another represents linear or branched, optionally hydroxy-substituted alkyl radicals containing 1 to 18 carbon atoms or an alkenyl radical containing 8 to 18 carbon atoms;c) amino acids containing 2 to 8 carbon atoms; andd) oligopeptides having an average molecular weight of about 500 to about 5000,at an elevated temperature.

    Abstract: A package construction for non-aqueous liquid detergent composition includes an outer package of water-permeable, water-insoluble plastic film or textile fabric and an inner package formed of water-soluble material, with an appropriate quantity, e.g. 100 grams, of the non-aqueous liquid composition sealed within the inner bag. A water-impermeable, water-insoluble outer bag or wrapper protects the package and its contents from exposure to moisture or high humidity prior to actual use in the aqueous wash bath. A preferred composition for use with this package construction is a non-aqueous liquid heavy duty no- or low-phosphate built laundry detergent composition which comprises a suspension of hydroxy polycarboxylic acid, e.g. sodium citrate, builder salt in liquid nonionic surfactant. The stability of the composition is improved by the addition of alkylene glycol monoalkyl ether solvents. Stability may be further enhanced by grinding the solid particulate matter, including builder salt, bleach and other minor ingredients to a particle size below about 15 microns. The non-aqueous liquid formulations remain pourable at temperatures as low as about 5.degree. C.
