Abstract

Raw materials that constitute reaction products of two compounds (1) and (2) having the general formulas (1) and (2), wherein the first compound (1) having the general formula (1): R 1 —(CH 2 ) a —(CHR 2 ) b —(CR 3 2 ) c —(CHR 4 ) d —(CH 2 ) e —R 5 , and the second compound (2) has the general formula (2): Y-A-Si(OR1)r(R2) 3-r , exhibit anti-wrinkle properties. They are used in laundry detergents, fabric softeners or textile treatment compositions that are applied to the textile outside a washing machine or a dryer.

First claim

What is claimed is:

1 . A raw material that constitutes the reaction product of two compounds (1) and (2) having the general formulas (1) and (2), wherein the first compound (1) has the general formula
R 1 —(CH 2 ) a —(CHR 2 ) b —(CR 3 2 ) c —(CHR 4 ) d —(CH 2 ) e —R 5   (1)
where R 1 , R 2 , R 3 , R 4 and R 5 , independently of one another, are each an OH, NH 2 , NHR′ and/or SH reactive group, and R′ is a linear or branched alkyl chain having 1 to 10 carbon atoms, an alkaryl or aralkyl group having 6 to 10 carbon atoms, or an aryl group having 5 to 10 carbon atoms, and a, b, c, d, and e can each be 0 or an integer between 1 and 10, with the condition that the sum of a+b+c+d+e is an integer greater than 1; and the second compound (2) has the general formula
Y-A-Si(OR1) r (R2) 3-r   (2)

where Y is NCO, Br or Cl, COOH, COCl , an epoxy, aldehyde or acrylate group; A is a linear or branched alkyl chain having 1 to 20 carbon atoms, an alkaryl or aralkyl group having 6 to 20 carbon atoms, or an aryl group having 5 to 20 carbon atoms; OR1 is a hydrolyzable group; R2 is a linear or branched alkyl group having 1 to 6 carbon atoms; and r is a number from 1 to 3.

2 . The raw material according to claim 1 , characterized in that at least 2, functional groups of compound (1) are reacted with compound (2).

3 . The raw material according to claim 1 , characterized in that the compound having the formula (1) only comprises OH as the groups R 1 to R 5 , and/or the sum of a+b+c+d+e in the compound having the formula (1) is greater than 1, but no more than 20.

4 . The raw material according to claim 1 , characterized in that the compound having the general formula (2) is a functional silane derivative that is capable of reacting with respect to OH groups and NH 2 groups.

5 . The method of producing a raw material according to claim 1 , characterized in that a solution is prepared from the first compound having the general formula (1) in an organic solvent, optionally at an elevated temperature, and, after cooling, the compound having the general formula (2) is added at room temperature, at a molar ratio of compound (2) to compound (1) of 1:1 to (2+b+2c+d):1, optionally while adding a starter or a catalyst.

6 . A textile treatment composition, comprising at least one raw material according to claim 1 in amounts of 1 to 50 wt. %.

7 . The textile treatment composition according to claim 6 , characterized in that the composition is a liquid to gel-like textile treatment composition, the at least one raw material being present in amounts of 1 to 20 wt. %.

8 . The textile treatment composition according to claim 7 , characterized in that the textile treatment composition is a liquid to gel-like composition on non-aqueous basis, comprising less than 5 wt. % water (according to Karl Fischer).

9 . A kit, composed of a spray dispenser and a textile treatment composition according to claims 7 .

10 . A method for using a textile treatment composition according to claim 7 , characterized in that the textile treatment composition is applied onto the dry or moistened, or still moist, textile by way of a spray dispenser.
