—(CH 2 ) s —; and combinations thereof;

(iii) each R is independently selected from the group consisting of H, C 1 -C 20 alkyl, C 1 -C 20 substituted alkyl, C 6 -C 20 aryl, C 6 -C 20 substituted aryl, alkylaryl, —OR 2 and combinations thereof;
(iv) each R 1 is independently selected from the group consisting of H, C 1 -C 8 alkyl or substituted alkyl, and combinations thereof;
(v) each R 2 is independently selected from the group consisting of H, C 1 -C 4 alkyl, substituted alkyl, aryl, substituted aryl, and combinations thereof;
(vi) each R 3 is a bivalent radical independently selected from the group consisting of aromatic, aliphatic and cycloaliphatic radicals with 2 to 30 carbon atoms, and combinations thereof; and
(vii) each R 4 is independently selected from the group consisting of H, C 1 -C 20 alkyl with molecular weight from 150 to 250 Dalton, aryl, substituted alkyl, cycloalkyl groups, and combinations thereof;
(viii) p is an integer of from about 2 to about 1000;
(ix) s is an integer of from about 2 to about 83;
(x) y is an integer of from about 0 to about 501;
(xi) n is an integer of from about 1 to about 50; and

b. from about 0.1% to about 50% by weight of the composition of a surfactant selected from the group consisting of anionic, cationic, amphoteric, nonionic surfactants, and combinations thereof; and
c. a material comprising an aldehyde group.

2. The composition of claim 1 , wherein at least 50% of the terminal R 4 groups have one or more tertiary amino groups.

3. A fabric care composition according to claim 2 wherein the organosiloxane polymer comprises a repeat unit having the structure of Formula II

to produce a copolymer comprising the first and second repeat unit having the structure of Formula III

wherein:
(i) said organosiloxane polymer comprising the following X moieties

(ii) each L is a linking bivalent alkylene radical, or independently selected from the group consisting of

—(CH 2 ) s —; and combinations thereof;

(iii) each R is independently selected from the group consisting of H, C 1 -C 20 alkyl, C 1 -C 20 substituted alkyl, C 6 -C 20 aryl, C 6 -C 20 substituted aryl, alkylaryl, —OR 2 and combinations thereof;
(iv) each R 1 is independently selected from the group consisting of H, C 1 -C 8 alkyl or substituted alkyl, and combinations thereof;
(v) each R 2 is independently selected from the group consisting of H, C 1 -C 4 alkyl, substituted alkyl, aryl, substituted aryl, and combinations thereof;
(vi) each R 3 is a bivalent radical independently selected from the group consisting of aromatic, aliphatic and cycloaliphatic radicals with 2 to 30 carbon atoms, and combinations thereof; and
(vii) each R 4 is independently selected from the group consisting of H, C 1 -C 20 alkyl, aryl, substituted alkyl, cycloalkyl groups, and combinations thereof;
(viii) s is an integer of from about 2 to about 8;
(ix) y is an integer of from about 0 to about 50;
(x) n is an integer of from about 1 to about 50
(xi) k is an integer selected from 0 to about 100; and
(xii) W is an alkylene radical derived from an organic molecule containing at least two groups selected from the group consisting of amino groups, hydroxyl groups, carboxy groups and mixtures thereof.

4. A fabric care composition according to claim 2 wherein the material comprising an aldehyde group is present in an amount of about 0.0001% to about 2% by weight of the composition.

5. A fabric care composition according to claim 2 wherein the surfactant is selected from linear or branched alkyl benzene sulfonate, alkyl sulfate, alkyl ethoxy sulfate, alkyl ethoxylate, alkyl glyceryl sulfonate, quaternary ammonium surfactant, ester quaternary ammonium compound and mixtures thereof.
