Abstract: 1,222,687. Softening textiles. PROCTER & GAMBLE CO. 5 June, 1968 [5 June, 1967 (2)], No.26713/68. Heading DIP. [Also in Division C5] A textile softener composition comprises, by weight of the total composition (a) from 1-25% of a softening agent selected from the group consisting of (I) zwilterionic compound of formula: in which R<SP>1</SP> and R<SP>2</SP> which may be the same or different, are each methyl, ethyl, n-propyl, iso-propyl, 2-hydroxyethyl or 2-hydroxypropyl, R<SP>3</SP> is a straight or branched C 20-30  alkyl or C 20-30 alkenyl chain which may be substituted with from 1-2 hydroxyl groups and may be interrupted by from 1-5 ether linkages and 1 amide linkage and R is an alkylene radical or a monohydroxyalkylene radical of from 1-4 carbon atoms (ii) tertiary amine oxides of formula: in which R<SP>4</SP> is a straight or branched C 20-30  alkyl or C 20-30 alkenyl chain and which may be interrupted by from 1-5 ether linkages and 1 amide linkage and which may carry from 1-2 hydroxyl substituents and from 1-2 chloro substituents, R<SP>5</SP> is a C 1-20 alkyl radical which may be interrupted by 1-5 ether linkages and 1 amide linkage and which may carry from 1 to 2 hydroxyl substituents and from 1 to 2 chloro substituents, R<SP>6</SP> is methyl ethyl, n-propyl, isopropyl, 2-hydroxyethyl or 2-hydroxypropyl or R<SP>5</SP> and R<SP>6</SP> together with the nitrogen atom may form a heterocyclic radical of from 4 to 6 carbon atoms, (III) tertiary phosphine oxides of formula: in which R<SP>7</SP> is an alkyl, alkenyl or monohydroxyalkyl radical of from 20 to 30 carbon atoms and R<SP>8</SP> and R<SP>9</SP> which may be the same or different are each alkyl or monohydroxyalkyl groups of from 1 to 4 carbon atoms (IV) ethoxylated alcohol compounds of formula: . in which R<SP>10</SP> is an alkyl radical of from 20 to 30 carbon atoms and X is an integer of from 3 to 45 (V) sulphated ethoxylated alcohol compounds of formula: in which R<SP>10</SP> is as defined above, M is an alkali metal, ammonium or substituted ammonium and y is an integer of from 1 to 20; (VI) anionic sulphonate compounds of formula: in which R<SP>10</SP> and M are as defined above and (VII) mixtures of two or more of (I) to (VI) (b) from 0 to 90% of a water soluble alkaline builder salt, (c) from 0.01 % to 1 % of a brightener compound (d) water. Specified alkaline builder salts of ingredient (b) are alkali metal, ammonium or substituted ammonium carbonates, borates, phosphates, polyphosphates, bicarbonates and silicates. Organic alkaline sequestrant builder salts specified are alkali metal, ammonium or substituted ammonium aminopolycarboxylates, alkali metal salts of phytic acid, water soluble salts of ethane-1-hydroxy-1, 1-diphosphonate, methylene diphosphonic acid, substituted methylene diphosphonic acid and polycarboxylate polymer and copolymers. Specified brightening agents, are bis-triazinylstilbene type, the bis-N-acylstilbene type, the stilbene triazole type and the dibenzothiophenedioxide type. Others mentioned are bisazoles, monoazoles, the pyrazoline type and the common type. The softener compositions may also contain other compatible softening agents such as ester, ether- or amide like condensation products containing polyalcohol, polyglycol, polyglycerol radicals and other suitable higher molecules, preferably long chain aliphatic radicals with 12 to 18 carbon atoms or sulphated or sulphonated long chain aliphatic alcohols, condensation product of long chain fatty acids with hydroxy- or amino sulphonic acid, as well as additives such as diluents e.g. sodium sulphate, tarnish inhibitors, bactericides, antiredeposition agents e.g. carboxymethyl cellulose, colours and perfumes. The compositions of the invention may be in granular, flake, tablet and liquid forms. The liquid forms containing solvents such as lower alcohols. to Specifications 987,417 and Disclaimers to Specifications 987,417 and 976,822 and reference is made to 1,081,556 and 1,222,686.
