Disclosed is the use of benzotropolone derivatives of formula whereinR, Rand Rindependently from each other are hydrogen; C-Calkyl; or COR;Ris hydrogen; or COORRis hydrogen; or C-Calkyl;Ris hydrogen; hydroxy; C-C-alkoxy; or &#x2014;O&#x2014;(CO)&#x2014;R;Ris hydrogen; C-Calkyl; or COR; orRand Rtogether may form a five or six membered ring; orRand Rtogether form a five or six membered ring; andR, R, Rindependently of each other are C-Calkyl;for protecting body-care and household products from photolytic and oxidative degradation.

Stabilization of household, body-care and food products by using benzotropolone containing plant extracts and/or related benzotropolone derivatives

The present invention relates to the use of selected metal complex compounds and ligands as oxidation catalysts as well as to a process for removing stains and soil on textiles and hard surfaces. The metal complex compounds have hydrazide ligands, preferably with electron withdrawing groups in the phenyl ring adjacent to the acyl group. Further aspects of the invention are formulations comprising such metal complex compounds, novel metal complex compounds and novel ligands.

Use of metal hydrazide complex compounds as oxidation catalysts

Disclosed is the use of benzotropolone derivatives of formula (1), wherein R, Rand Rindependently from each other are hydrogen; C-Calkyl; or COR; Ris hydrogen; or COORRis hydrogen; or C-Calkyl; Ris hydrogen; hydroxy; C-C-alkoxy; or -0-(CO)&#x2014;R; Ris hydrogen; C-Calkyl; or COR; or Rand Rtogether may form a five or six membered ring; or Rand Rtogether form a five or six membered ring; and R, R, Rindependently of each other are C-Calkyl; for protecting body-care and household products from photolytic and oxidative degradation. 

The present invention relates to the use of metal complex compounds with terpyridine ligands as oxidation catalysts. The present invention relates also to formulations comprising such metal complex compounds, to novel metal complex compounds, and to novel ligands. The metal complex compounds are used especially tor improving the action of peroxides, for example in the treatment of textile material, without at the same time causing any appreciable damage to fibres and dyeings.
