Abstract

Fabric treatment compositions 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 by direct covalent bonds between the silicon and/or phosphorus atoms and a carbon atom.

The functional groups are selected to impart lubricating properties to the particles.

Claims

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;

$\begin{array}{cc}\stackrel{+}{{\mathrm{—<br><br>R}}^3<br><br>{\mathrm{—<br><br>NR}}^4<br><br>R^4<br><br>R^4}& \left(\mathrm{III}\right)\end{array}$

in 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

in which each R_1a group is independently selected from C_1-4 alkyl or hydroxyalkyl groups or C_2-4 alkenyl groups;

each R_2a group is independently selected from C_8-28 alkyl or alkenyl groups;

R_3a is a linear or branched alkylene group of 1 to 5 carbon atoms,

X is

and p is 0 or is an integer from 1 to 5,

with the proviso that one of R_1a and R_2a is an alkylene group of at least 3 carbon atoms attached to said silicon or phosphorus atom;

(v) a group of the formula;

in which R_1a, p and R_2a are as defined above;

(vi) a group of the formula;

in 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;

in 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.

2. A composition as claimed in claim 1 in which —

Y-T is an alkyl group of from 6 to 20 carbon atoms.

3. A composition as claimed in claim 1 in which each R² is lower alkyl of from 1 to 6 carbon atoms.

4. A composition as claimed in claim 1 in which at least one of R² is an alkyl group of at least 8 carbon atoms.

5. A composition as claimed in claim 4 in which each R² is an alkyl group of at least 8 carbon atoms.

6. A composition as claimed in claim 1 in which T is selected from hydrogen, alkyl, ether, carboxylic acid, SO₃ and SO₄ groups, phosphate and phosphonate.

7. A composition as claimed in claim 1 in which the particles comprise two or more different functional groups selected from formulas (I) to (VII).

8. A composition as claimed in claim 1 wherein the particles comprise layers which further comprise atoms selected from magnesium, aluminiun, nickel, zirconium and mixtures thereof.

9. A composition as claimed in claim 1 wherein the particles are of a clay in which the organic functional groups have been introduced during formation of the clay.

10. A composition as claimed in claim 1 wherein the particles are of an organophyllosilicate.

11. A composition as claimed in claim 1 which is a main wash detergent composition and wherein the textile compatible carrier comprises a detergent active compound.

12. A composition as claimed in claim 1 which is a fabric conditioner comprising one or more fabric softening or conditioning agents.

13. A composition as claimed in claim 1 comprising one or more further components selected from builders and enzymes.

14. A composition as claimed in claim 1 comprising from 0.01% to 50% by weight of the particles.

15. A composition as claimed in claim 14 comprising from 0.1% to 20% by weight of the particles.

16. A method of treating a fabric comprising contacting a fabric with the fabric treatment particles as defined in claim 1.

17. A method of treating a fabric to provide enhanced lubricating properties to the fabric comprising contacting a fabric with the fabric treatment particles as defined in claim 1.

18. A method of treating a fabric to decrease the Kawabata shear of the fabric measured according to the Kawabata Shear Test defined herein, comprising contacting a fabric with the fabric treatment particles as defined in claim 1.

19. A method of treating a fabric to provide improved softness and/or ease of ironing and/or anti-wrinkle properties and/or anti-abrasion properties, comprising contacting a fabric with the fabric treatment particles as defined in claim 1.
