Composition for lightening or dyeing keratin fibers with a low amount of oxidizing agent

Composition for dyeing keratin fibers, consisting of:

• at least 40% by weight of fatty substances which are emulsions in water and free of carboxylic acid groups relative to the total weight of the composition;
• wherein the fatty substances free of carboxylic acid groups are selected from the group consisting of:
• liquid hydrocarbons, liquid fatty alcohols, and any mixture thereof, and
• wherein the composition is free of any fatty acid comprising a carboxylic acid group, any fatty substance comprising a COO group and any fatty substance having oxyalkylene units and/or glycerol units;
• at least one alkalizing agent, wherein the at least one alkalizing agent comprises monoethanolamine alone or in combination with other alkalizing agents;
• at least one surfactant,
• at least two oxidative dye precursors comprising one or more primary intermediates and one or more couplers wherein the oxidative dye precursors are aromatic diamines, amino phenols, aromatic diols and/or derivatives thereof wherein the precursors are un-neutralized and/or are cosmetically acceptable amine salts and/or aromatic phenol or diol salts,
• at least one oxidizing agent at a concentration of from 1.5% to 2.1% by weight by weight relative to the total weight of the composition,
• at least one chelant in a range of from about 0.01% to about 5% by weight of the total weight of the composition, wherein the at least chelant comprises aminocarboxylic acid comprising diethylenetriamine-N, N′, N″-polyacids, ethylenediamine disuccinic acid (EDDS), ethylenediamine-N,N′ diglutaric acid (EDDG), glycinamine-N,N′disuccinic acid (GADS), 2-hydroxypropylenediamine-N—N′-disuccinic acid (HPDDS), ethylenediaminetetraacetic acid (EDTA), ethylenedicysteic acid (EDC), ethylenediamine-N—N′-bis(ortho-hydroxyphenyl acetic acid) (EDDHA), diaminoalkyldi(sulfsuccinic acids) (DDS), N, N′-bis(2-hydroxybenzyl)ethylenediamine-N,N′diacetic acid (HBED), ethylene diamine tri(methylene phosphonate), hexamethylene diamine tetra(methylene phosphonate), polyethyleneimine, polyphosphoric acid, etidronic acid, methylglycine diacetic acid, N-(2-hydroxyethyl)iminodiacetic acid, minodisuccinnic acid, N, N-dicarboxymethyl-L-glutamic acid, N-Lauroyl-N, N′, N″ ethylenediamine diacetic acid, a salt thereof, or a mixture thereof,
• water at a wt % of less than 50 wt % relative to the total weight of the composition;
• alcohol consisting of ethanol, propanol, isopropanol, propylene glycol, hexylene glycol, dipropylene glycol, propylene carbonate or any mixture thereof;
• and,
• at least one or more of a pH modifier, a thickener, a conditioning agent, an anionic polymer, a cationic polymer, a nonionic polymer, an amphoteric polymer, a zwitterionic polymer, an antioxidant, a penetrating agent, a pigment, a film forming agent, a sequestrant, a perfume, a dispersing agent, a radical scavenger, a ceramid, a preservative, an opacifying agent, and any combination thereof.
