The invention relates to oral and dental hygiene and cleaning agents which contain, in relation to their weight, between 0.001 and 25% by weight polylactic acid particles and between 1 and 30% by weight precipitated silicic acid(s) with a specific surface area according to ISO 5794-1, Appendix D, of ≦60 m
2
/g. said agents exhibit a reduced damaging action in comparison to pure silicate-based compositions. In particular, the sensitivity of the teeth during and after the cleaning process is reduced.

The present invention provides compositions comprising metal complexes, and related methods. In some embodiments, metal complexes of the invention may be useful as catalysts for chemical reactions, including metathesis reactions, wherein the catalysts exhibit enhanced activity and stereoselectivity. In some embodiments, the invention may advantageously provide metal complexes comprising a stereogenic metal atom. Such metal complexes may be useful in enantioselective catalysis.
