    Abstract: The present disclosure relates to an adjuvant composition comprising lecithin; and, an organosilicon surfactant of formula (I): R1—Si(CH3)2—Z  (I) wherein: R1 is a branched monovalent hydrocarbon group of from 5 to 8 carbon atoms containing at least two methyl groups; Z is R2 or R3; R2 is CH2CH2CH2—OC2H4—O)a(C3H6O)b(C4H8O)c—R4 in which R4 is hydrogen, a linear or branched monovalent hydrocarbon group of from 1 to about 4 carbon atoms or an acyl group, subscript a is from 1 to about 20, subscript b is from 0 to about 19, subscript c is from 0 to about 19 and the sum of subscripts a, b and c is from 1 to about 20; and, R3 is —CH2CH2CH2—O—CH(OH)CH2—N+(CH3)2—R5 [X−] in which R5 is a linear or branched hydrocarbon group of from 1 to about 4 carbon atoms or an acetyl group and X− is a saturated or unsaturated carboxylate anion of from 2 to about 22 carbon atoms optionally containing 1 or 2 hydroxyl groups.
