Patent number: 6211139
Abstract: A composition comprising: (a) a compound of the following structural formula:
wherein each of R* and R** is independently a linear, branched or cyclic alkylene group containing 2 to 12 carbon atoms, wherein no two nitrogen atoms are separated by fewer than 2 carbon atoms; each of A1, A2, A3, A4, and A5 is independently a straight or branched alkylene containing 2 to 4 carbon atoms; each of R1, R2, R3, R4, and R5 is independently —H or RAC(O)— wherein RA is straight or branched alkyl or alkenyl containing 7 to 21 carbon atoms and 0 to 4 carbon-carbon double bonds; provided that at least one of R1, R2, R3, R4, or R5 is RAC(O)—; each of Q1, Q2 and Q3 is independently —H, —CH3, —C2H5, —C3H7, —C4H5, benzyl, —CH2COOH, or —CH2COOA−; or, if R* is a —CH2CH2— group, Q1 and Q3 together or Q1 and Q2 together may be a —CH2CH2— group to form a six-membered piperazine ring; or, if R** is a —CH2CH2— group,
