1. Fabric treatment composition comprising a textile compatible carrier and particles having a layered structure comprising oxygen atoms and silicon and/or phosphorus atoms, and comprising organic functional groups which are bonded to silicon and/or phosphorus atoms in the layers by direct covalent bonds between the silicon and/or phosphorus atoms and a carbon atom, characterised in that the functional groups are selected from:

  • (i) a group of the formula;




    Y-T 



    (i) in which;

    Y comprises a chain of at least 6 carbon atoms optionally interrupted by one or more heteroatoms selected from N, O and S providing there are at least 3, preferably at least 4 carbon atoms for each heteroatom in the chain, Y being linked to said silicon or phosphorous atom through a carbon atom, and T represents H or a terminal group which is not capable of self-cross-linking and/or forming covalent bonds to cellulosic and/or proteinaceous fibres during domestic washing and rinsing cycles;

    (ii) a group of the formula;




    R1

    NR2R2



    (II) in which;

    R1 represents an alkylene group of at least 4 carbon atoms, each R2 is independently lower alkyl and —

    NR2R2 is preferably, but need not be, a terminal group;

    (iii) a group of the formula;

    embedded imagein which;

    R3 represents an alkylene group of at least 3 carbon atoms, each R4 is independently selected from alkyl groups of from 1 to 25 carbon atoms provided at least one R4 is lower alkyl of 1 to 16 carbon atoms, (iv) a group of the formula embedded imagein which each R1a group is independently selected from C1-4 alkyl or hydroxyalkyl groups or C2-4 alkenyl groups;

    each R2a group is independently selected from C8-28 alkyl or alkenyl groups;

    R3a is a linear or branched alkylene group of 1 to 5 carbon atoms, X is embedded imageand p is 0 or is an integer from 1 to 5, with the proviso that one of R1a and R2a is an alkylene group of at least 3 carbon atoms attached to said silicon or phosphorus atom;

    (v) a group of the formula;

    embedded imagein which R1a, p and R2a are as defined above;

    (vi) a group of the formula;

    embedded imagein which;

    T is as defined above, R5 represents a group of at least one carbon atom, preferably at least 3 carbon atoms, which may be interrupted by one or more heteroatoms selected from N, O and S providing there are at least 3 carbon atoms for each heteroatom, n is an integer of at least 6; and

    (vii) a group of the formula;

    embedded imagein which;

    T and R5 are as defined above, each R6 independently represents an alkyl group, a fluorinated alkyl group, an amino substituted alkyl group, an alkyl group substituted with a sugar moiety, or a sidechain comprising an ethoxylated and/or propoxylated chain, and x is an integer of at least 5.
