摘要:
Diglycidyl-substituted pteridine compounds of the general formula: ##STR1## wherein n is the whole number 1 or 2, R.sub.2 and R.sub.2 are the same or different, and are either hydrogen, a hydrocarbon radical, or together form a 5- or 6-membered carbocyclic or heterocyclic ring; processes for their preparation; and compositions and methods for their use as cytostatic agents.
摘要:
This invention is directed to compositions of the developer-coupler type for the dyeing of hair, consisting essentially of substituted benzotriazoles as coupling components and, as developer components, the conventional components used in oxidation dyes.
摘要:
This invention is directed to novel bis-(2,4-diaminophenoxy)-alkanes and a method of preparing them. This invention is also directed to the use of said bis-(2-4-diaminophenoxy)-alkanes, or the salts thereof, as coupler components in developer-coupler oxidation hair dyeing compositions.
