What is claimed is: 1. 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. 2. The composition according to claim 1 the oxidizing agent is selected from the group consisting of hydrogen peroxide, percarbonates, persulphates, and mixtures thereof. 3. The composition according to claim 1 wherein the primary intermediates are selected from the group consisting of toluene-2,5-diamine, 2-methoxymethyl-pphenylenediamine, N,N-bis(2-hydroxyethyl)-p-phenylenediamine, p-aminophenol and mixtures thereof. 4. The composition according to claim 1 wherein the couplers are selected from the group consisting of resorcinol, methyl-resorcinol, naphthol, m-aminophenol, 4-amino-2-hydroxytoluene, 2-methyl-5-hydroxyethylaminophenol, 2,4-diaminophenoxyethanol, 2-amino-4-hydroxyethylaminoanisole and mixtures thereof. 5. The composition according to claim 1 wherein the surfactants are selected from the group consisting of non-ionic surfactants, anionic surfactants and mixtures thereof, preferably, non-ionic surfactants. 6. Process for lightening or dyeing keratin fibers wherein the composition according to claim 1 is applied to the keratin fibers. 7. The composition of claim 1 , wherein the at least one chelant is in a range of from about 0.1% to about 3% by weight of the total weight of the composition. 8. The composition of claim 1 , wherein the at least one chelant is in a range of from about 0.25% to about 1% by weight of the total weight of the composition. 9. The composition of claim 1 , wherein the at least one chelant further comprises a carboxylic acid, a phosphonic acid, a polyphosphoric acid, a salt thereof, or a mixture thereof.
