Homogeneous, essentially nonaqueous adjuvant compositions with buffering capability

A homogeneous, essentially nonaqueous adjuvant composition consisting essentially of a spray oil having a minimum of 85% of unsulfonated residue value, a surfactant blend selected from the group consisting of (a) fatty alkanomides of the formula ##STR20## wherein R is a C.sub.6 -C.sub.25 alkyl group;

• R and R'are the same or different and are independently selected from the group consisting of hydrogen, --CH.sub.2 CH.sub.2 OH [or]and ##STR21## (b) PEG esters of the formula ##STR22## wherein R.sup.2 is a C.sub.2 -C.sub.25 fatty alkyl, R.sup.3 is a C.sub.2 -C.sub.25 fatty alkyl or hydrogen and m is a number from 1 to 100,
• (c) silicone surfactants of the formula ##STR23## wherein x is a number from 0 to 5, y is a number from 1 to 5, a is a number from 3 to 25, b is a number from 0 to 25, n is a number from 2 to 4 and R.sup.6 is a hydrogen, an alkyl group having 1 to 4 carbon atoms or an alkyl ester group having 1 to 4 carbon atoms,
• (d) ethoxylated fatty acids ##STR24## wherein R.sup.7 is a C.sub.6 -C.sub.25 alkyl group, p is a number from 1 to 100,
• (e) alkyl ethoxylates
• R.sup.8 O(CH.sub.2 CH.sub.2 O).sub.q H
• wherein R.sup.8 is alkyl group and q is a number from 1 to 100,
• (f) alkylphenol ethoxylates ##STR25## wherein R.sup.9 is hydrogen or C.sub.1 -C.sub.20 alkyl, R.sup.10 is hydrogen or C.sub.1 -C.sub.20 alkyl and n is a number from 1 to 100,
• (g) polypropylene glycols ##STR26## wherein t is a number from 1 to 100, (h) amine ethoxylates ##STR27## wherein g and h are numbers from 1 to 100 and R.sub.11 is a C.sub.1 -C.sub.25 alkyl and
• (i) mixtures of any of the above surfactants (a) through (h), and a buffering agent is in an amount sufficient to reduce the pH to below 7, wherein said surfactant blend is mixed with sorbitan fatty acid ester and/or a polyethoxylated derivative of a sorbitan fatty acid ester.
