Patent ID: 7989411

Claim:
A composition which comprises: (i) at least one component represented by formula (1), wherein, independently, one of the symbols B1, B2, B3 represents an acyl group represented by —CO—R and the remaining ones represent H; (ii) at least one component represented by formula (1), wherein, independently, two of the symbols B1, B2 and B3 represent an acyl group represented by —CO—R and the remaining one represents H; (iii) at least one component represented by formula (1), wherein, independently, each one of the symbols B1, B2 and B3 represents an acyl group represented by —CO—R; and (iv) at least one component represented by formula (1), wherein each one of B1, B2 and B3 represents H, with the proportion by weight of components (i)/(ii)/(iii) of 60-90/10-35/less than 10, wherein R′ represents H or CH 3 , and each one of m, n, or l represents, independently, a number from 0 to less than 9, the sum of m, n and l being in the range of over 5 and less than 9, wherein in the acyl group represented by —CO—R, R represents an alkyl or alkenyl group, linear or branched, of 6 to 9 carbon atoms, and wherein the proportion by weight (i)+(ii)+(iii)/(iv) is in the range of 2.0:0.5 to 0.5:3.
