  • Patent number: 6458343
    Abstract: A composition comprising a compound selected from the group consisting of compounds of the following structural formula (1A): and the protonated and quaternized derivatives thereof of the following structural formula (1B): wherein R1 is a C2 to C22 hydrocarbyl group or is an ether group of the formula R—O—(R3)v—C3H6—, where v is 0 to 10 and R is a C1 to C22 hydrocarbyl group; R2 is hydrogen or a C1 to C22 hydrocarbyl group, or is  and (R3)yH, where y is 1 to 100; each R3 is independently selected from a group consisting of an ethylene oxide group (C2H4O), a propylene oxide group (C3H6O), a butylene oxide group (C4H8O) and mixtures thereof; each R4 is a C3 to C2, hydrocarbyl group; R5 is hydrogen or a C1 to C8 hydrocarbyl group; and x is 1 to 100; and A− is an anion.

  • 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,
