Non-oxidative permanent dye formulation for hair and synthetic fibers

A highly effective, easily employed permanent dye and gel composition for use on natural and synthetic fibers free from oxidants and activators for imparting a desired color into the fibers in a permanent and long-lasting, durable manner, and in a single one-step application said composition consisting essentially of

• A. between about 0.3% and 1.0% by weight of at least one certified dyestuff selected from the group consisting of dyestuffs designated as F,D&C dyes and D&C dyes;
• B. between about 1.0% and 2.0% by weight of xanthan gum;
• C. between about 1.0% and 1.50% by weight of ammonium chloride;
• D. between about 1.25% and 25% by weight of a mercaptan based reducing agent;
• and
• E. water forming the balance with the resulting pH of the composition ranging between about 3.0 and 7.0.

A single, one-step application process for permanently imparting a desired color into natural or synthetic fibers in a long-lasting durable manner comprising the steps of:

• A. mixing between about 0.001% and 5.0% by weight of a desired dyestuff into an aqueous solution wherein said dyestuff comprises a certified dyestuff selected from the group consisting of F,D&C dyes and D&C dyes;
• B. adding to the mixture of step A between about 0.01% and 8% by weight of a gelling agent comprising one selected from the group consisting of guar and cellulosic based compositions;
• C. intermixing therewith between about 0.01% and 4.0% by weight of ammonium chloride, with the ratio of the gelling agent and ammonium chloride being varied to control the viscosity of the final composition to between about 1,000 and 20,000 centipoise, forming a permanent dyestuff gel composition.
• D. intermixing into said permanent dyestuff gel composition between about 0.01% and 25% by weight of a mercaptan based reducing agent, with said reducing agent comprising at least 0.5% by weight of the dyestuff and being added to the composition immediately prior to use of the composition on the fiber;
• E. applying the fully formulated permanent dyestuff gel composition to the fibers to be dyed by rubbing or embrocating the composition into the fibers;
• F. allowing the permanent dyestuff gel composition to remain on the fibers for between about 5 and 30 minutes;
• and
• G. rinsing the permanent dyestuff gel composition from the fibers, leaving the fibers with the precisely desired permanent coloring embedded therein.

• F. allowing the permanent dyestuff gel composition to remain on the fibers for between about 5 and 30 minutes;
• G. applying heat to the fibers after the permanent dyestuff gel composition has been applied to the fibers with the temperature of the applied heat ranging between about 30.degree. C. and 70.degree. C.;
• and
• H. rinsing the permanent dyestuff gel composition from the fibers, leaving the fibers with the precisely desired permanent coloring embedded therein.
