Abstract

Procedure for obtaining compositions to soften fabrics, characterized in that in a first stage, a granular composition (a) is formed from a clay of the smectic type, with an ion exchange capacity of at least 50 meq/100 g .; in a second step, about 1 to 40% by weight of a substantially water-insoluble quaternary ammonia unsightly agent of the formula is contacted (b): **(See formula)** where R1 and R2 represent hydrocarbyl groups having from about 10 to 22 carbon atoms, R3 and R4 represent hydrocarbyl groups containing from about 1 to 4 carbon atoms, X is an anion and n is an integer from 1 to 3; with (c) from 1 to 40% by weight approximately of a compatibilizing agent selected from the group consisting of: (i) fatty acids with approximately 8 to 30 carbon atoms in the alkyl chain; (ii) compounds selected from the group consisting of mono-, di- and tricarboxylic benzene acids, containing from 20 to 2 hydroxyl functions; and (iii) an amino-substituted compound of the formula: **(See formula)** wherein R1 represents an alkyl group containing from about 1 to 22 carbon atoms; R2 and R3 represent alkyl groups containing from about 1 to 10 carbon atoms, or hydrogen, but provided that not more than one of the R2 and R3 groups can be hydrogen; and Y represents -CONH2; -CON (R4) 2; or -COOH; wherein R4 represents an alkyl group containing from about 1 to about 4 carbon atoms or hydrogen; and (iv) mixtures of the compounds described above; and in a third step, the resulting combination of (b) with (c), is added to approximately 2-90% by weight of composition (a), based on the weight of the clay; so that in carrying out this sequence of operating steps, component (b) is coated with (c) and direct contact of (a) with (b) is avoided.
