Abstract:
Process of treating the hair comprising first permanently waving the hair with a thio reducing agent and thereafter applying to the hair an aqueous solution containing a neutralizing agent and a water-soluble diimide compound.
Abstract:
The process of dyeing keratinic fibers comprising first treating the fibers with an aqueous solution of water-soluble keratinic fiber reactive polysulfyhdryl polymer which has -SH groups that react with the keratinic fiber, said polymer being present in amounts of about 0.1-10 percent by weight of the aqueous solution then dyeing the keratinic fibers with a dye composition selected from the group consisting of reactive dyes and metallized monoazo acid dyes.
Abstract:
A hair dyeing composition comprises an aqueous solution of a hair coloring amount of a dye compound having the formula A-NR(CH2)n-NHR'' wherein R and R'' each independently are selected from the group consisting of hydrogen, lower alkyl and lower alkoxy, n is an integer of 2-6 and A is selected from the group consisting of anthroquinone, azo and benzene. The composition contains 0.01 to 3 percent of said dye compound and has a pH of about 4-10.
Abstract:
NEW HAIR DYEING COMPOUND RESPONDING TO THE FORMULA
1-(CH3-CO-NH-(CH2)N-NH-)ANTHRAQUINONE
IN WHICH N IS A WHOLE NUMBER LYING BETWEEN 2 AND 6 INCLUSIVE AND METHOD FOR MAKING THE SAME AS WELL AS AN AQUEOUS SOLUTION THEREOF AS A COMPOSITION FOR DYEING HAIR.
Abstract:
Compounds suitable for use in one step hair and keratin fiber dyeing compositions which do not require the use of separate dye modifiers and are exceptionally color stable, having the formula IN WHICH R is selected from the group consisting of hydrogen and alkyll R1 is selected from the group consisting of alkyl, alkoxy, and dialkylamino, R4 which can be in position 5 or 6 on the ring is selected from the group consisting of hydrogen, halogen, hydroxy, alkyl, alkoxy and NH2, and at least one of said R1 and R4 is said dialkylamino or said NH2 .
