摘要:
Synthetic fibers and synthetic fiber textile materials finished with mineral oil finishes, silicone oil finishes or both can be simultaneously stripped of these finishes and dyed in one liquor comprising as essential ingredientsa) anionic and/or amphoteric surfactants,b) dyes, andc) optionally further compounds selected from the group consisting of the nonionic surfactants, the terpene hydrocarbons/alcohols, sorbitol esters and their alkoxylates, fatty acid ethanolamides, alkylpolyglycosides and solvents.The treatment is carried out at pH 4.0 to 7.5 at 80-110.degree. C. and at a liquor ratio of 5:1 to 100:1.
摘要:
Stable compositions for dyeing of human hair in an aqueous carrier, providing durable, light-fast hair colorations, comprisinga) 0.0001% to 2.5% by wt. of at least one cationic directly acting hair dyestuff;b) 0.1% to 10% by wt. of at least one zwitterionic (amphoteric) surfactant; andc) 0.1% to 5% by wt. of at least one water-soluble UV-absorbing compound bearing an anionic group,all percentages calculated to the total composition.
摘要:
New condensation products of the formula ##STR1## wherein R represents alkyl, cycloalkyl, aralkyl, aryl, or halogen, M represents hydrogen, an alkali metal or alkaline earth metal or an ammonium group, and n is a number from 1 to 3; these products are particularly useful as dyeing assistants for dyeing synthetic polyamide fibres with anionic dyes.
