Abstract:
Disclosed is the use of benzotropolone derivatives of formula wherein R1, R2 and R7 independently from each other are hydrogen; C1-C3alkyl; or COR8; R3 is hydrogen; or COOR9 R4 is hydrogen; or C1-C3alkyl; R5 is hydrogen; hydroxy; C1-C3-alkoxy; or —O—(CO)—R10; R6 is hydrogen; C1-C3alkyl; or COR8; or R5 and R6 together may form a five or six membered ring; or R6 and R7 together form a five or six membered ring; and R8, R9, R10 independently of each other are C1-C30alkyl; for protecting body-care and household products from photolytic and oxidative degradation.
Abstract:
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.
