- —NO2, —NH2, —NHR′, or —NR′2;
- n is a number from 1 to 5;
- R′ is H or any of the lower alkyls ranging from C1 to C6;
- wherein R″ is
- or R′;
- R′″ is the hydrocarbon backbone of fatty acids;

- where there are two or more R′, R″, R′″, R″″, or R′″″ groups attached to the same carbon, each R′, R″, R′″, R″″, or R′″″ group may be the same as or different from the other R′, R″, R′″, R″, or R′″ groups attached to that carbon;
- (ii) an active agent according to the structure of Formula (VIII)
- or a salt thereof;
- and
- (iii) isohexadecane, polysorbate, phenoxyethanol, one or more C12-C16 alcohols, and one or more polyols.
