1. A dynamite composition of at least nitrate esters, oxidizer salts, carbonaceous fuel, antiacid the improvement comprising:
- the incorporation of from about 0.5 to about 3.0% by weight of a desensitizer selected from the group consisting of;
##STR19## and ##STR20## and ##STR21## and ##STR22## wherein R1 is a C3 to C10 group, but not a benzyl ring, which can contain elements other than carbon and hydrogen, and R2 is a C8 to C20 group and R3 is a C1 to C3 group.
