Abstract

Suggested is a method for identifying fragrance compounds with low environmental impact and high degree of sustainability encompassing the following steps: (a) providing a fragrance compound or a fragrance composition of interest; (b) calculating scores for each of the following parameters (b1) biodegradability; (b2) biodiversity; (b3) carbon dioxide impact; (b4) process safety with regard to ecological toxicity; (b5) process safety with regard to human toxicity; (b6) land use; (b7) renewability; (b8) traceability; (b9) waste generation; and (b10) water consumption and/or pollution, (c) summing up all scores and calculate the average product sustainability score (PSC); and (d) proceed with those candidates showing a PSC of at least 70.

First claim

The invention claimed is:

1. A method for identifying fragrance compounds with low environmental impact and high degree of sustainability encompassing the following steps:
(a) providing a fragrance compound or a fragrance composition of interest;
(b) measuring performance of the fragrance compound or fragrance composition for each of the following parameters followed by normalizing to a scale from 0 to 100 without dimension to identify fragrance compounds with low environmental impact and high degree of sustainability, based on calculating scores for each of the following parameters:
(b1) biodegradability;
(b2) biodiversity;
(b3) carbon dioxide emission;
(b4) process safety with regard to ecological toxicity;
(b5) process safety with regard to human toxicity;
(b6) land use;
(b7) renewability;
(b8) traceability;
(b9) waste generation; and
(b10) water consumption and/or pollution,

(c) summing up all scores and calculating the average product sustainability score (PSC); and
(d) proceeding with those candidates showing a PSC of at least 70, wherein
(i) the score for biodegradability of the compound or the composition is calculated according to OECD Method 301/302;
(ii) the score for the overall biodiversity S(BIO) is calculated according to the following equation (1):

wherein M stands for the molar mass of a specific compound and D stands for its biodiversity on condition that the formulation contains a to z compounds;
(iii) the score for the overall carbon dioxide impact S(CO 2 ) is calculated according to following equation (2):
