摘要：
Active substances for which controlled release is desired, are released by a process in which a shaped body (S) containing a composition (C) comprises a silicone-containing polymer (P) containing at least one Si—C bonded amino acid group and active substance (A) is contacted with water, resulting in the release of active substance (A) from the composition (C).
