Claim:
Cyclodextrinyl-containing organosilicon compounds comprising units of the formula A a R b X c H d SiO (4−a−b−c−d)/2 (I) where A each is the same or different and is a radical of the formula CD—R 2 — (II) where CD is a mono- or multivalent, derivatized or underivatized cyclodextrin residue, and R 2 is a divalent, triazinylene radical, R each is the same or different and is a substituted or unsubstituted hydrocarbyl radical optionally interrupted by oxygen atoms, sulfur atoms and/or nitrogen atoms, X each is the same or different and is a radical of the formula —OR 1 , where R 1 is a hydrogen atom or substituted or unsubstituted hydrocarbyl optionally containing ether oxygen atoms, a is 0, 1 or 2, b is 0, 1, 2 or 3, c is 0, 1, 2 or 3, and d is 0, 1, 2 or 3, with the provisos that: the sum a+b+c+d is≦3; and the organosilicon compound has at least one A radical per molecule; in not more than 90% of units of the formula (I), is the sum of a+b+c+d equal to 0; wherein the cyclodextrin oxygen atom used for the chemical attachment of CD to R 2 may be replaced by S, NH or NR 0 where R 0 has one of the meanings indicated above for R.
