The novel primary intermediate, 1-(5-amino-2-hydroxyphenyl)ethane-1,2-diol and a method for producing same, are disclosed. The novel intermediate can be employed as a replacement for p-aminophenol in oxidation dye formulations.

Substituted p-aminophenol, process of preparation and use in dyeing hair

The invention provides compositions and methods for the oxidative coloring of human hair. The compositions of the invention contain as a primary dye intermediate a 1-(4-aminophenyl) pyrrolidine, or a cosmetically acceptable salt thereof. The compositions may also contain at least one other primary intermediate and conventional coupling compounds, in addition to an oxidizing agent and other components typically used in oxidative hair dye preparations. Preferred dye intermediates in the compositions of the invention include 1-(4-aminophenyl) pyrrolidine and 1-(4-amino-3-methylphenyl) pyrrolidine, or cosmetically acceptable salts thereof, which produce intense neutral colors when used in admixture with a suitable coupling agents, such as 3-aminophenol, in conventional hair dye base formulations.

Oxidative hair dye compositions and methods containing

A two part aqueous composition for coloring human hair which forms a gel on mixing of an alkaline aqueous lotion first part having a pH of from about 7 to about 11 containing from about 0.005% by weight to about 5% by weight of at least one primary intermediate and at least one coupler for the formation of oxidation dyes, from about 0.1% to about 5% of a monomeric quaternary ammonium compound having one long chain alkyl substituent, from about 0.5% to about 15% by weight of an amphoteric surfactant and at least 70% by weight water, and an aqueous developer second part having a pH of from about 2 to about 6 containing from about 0.5% by weight to about 40% by weight of a peroxide oxidizer and from about 0.1% by weight to about 20% by weight of a water insoluble anionic polymer which dissolves in the formed gel.

Two-part aqueous composition for coloring hair, which forms a gel on

A process of imparting antistatic surface modifications to protein fibers by treating them with a polymeric high molecular weight quanternary ammonium salt having long chain organo groups as side chains which contain at least 12 carbon atoms in the chain.

Process for treating protein fibers to impart antistatic surface

A hair conditioning composition containing an amino functional silicone polymer in aqueous emulsion such as amodimethicone, and an effective amount for increasing the combability of hair of a cationic surfactant-emulsifier containing at least one long chain fatty acid residue which has between 12 and 18 carbon atoms, and an effective amount for increasing the combability of hair and for improving the durability of the conditioning effect of at least one cationic polymer in an aqueous carrier. The process of the invention involves the application of the aforementioned conditioning composition before or after shampooing whereby the durability of the conditioning effect is further enhanced.
