DUSTLESS DYESTUFF PREPARATIONS

摘要

Solid formulations of organic dyestuffs, or of optical brighteners, characterized in that they contain a mixture of (a) 70-90% by weight of a mineral oil, (b) 0.5-10% by weight of an amide of the formula in which R represents C10-C22-alkyl or -alkenyl, R1 represents H or C1-C4-alkyl, or the two R1's together represent a 1,2-ethylene bridge and R2 represents alkylene, and R3 represents H, C1-C6-alkyl or phenyl, (c) 0.5-15% by weight of a non-ionic surface-active agent and (d) 0-8% by weight of a cationic or anionic surface-active agent, and processes for the production of low-dust and low-foam solid dyestuff formulations.
