Abstract:
A computer-implemented method can be used for controlling sorting of plastic compounds. The method involves providing a computer-based database containing entries on a plurality of markers each identifying a specific plastic compound; receiving scan data from a sample of a plastic compound; identifying a marker in the sample of the plastic compound based on the received scan data and the plurality of markers of the database; and sorting of plastic compounds based on the identified marker of the sample of the plastic compound.
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.
