1. A hair coloring and/or bleaching composition comprising:
a first aqueous component (i) comprising one or more oxidizing agent(s) in a cosmetically acceptable carrier; and,
a second aqueous component (ii) comprising one or more alkalizing agent(s) comprising ammonia, its salts or mixtures thereof in a cosmetically acceptable carrier,
wherein the first aqueous component (i) and the second aqueous component (ii) are mixed in a ratio ranging from 5:1 to 1:5, and the total composition after mixing the first aqueous component (i) and the second aqueous component (ii) comprises:
a) a linear and/or branched C12 to C30 fatty alcohol at from 0.5% to 20% relative to the total composition after mixing,
b) one or more polyoxyethylene C12-C30 alkyl ether nonionic surfactants at from 0.1% to 5% relative to the total composition after mixing,
c) a phosphate ester compound selected from the group consisting of alkyl phosphate ester, alkoxylated alkyl phosphate esters, and mixtures thereof at from 0.3% to 8% relative to the total composition after mixing;
d) an anionic surfactant other than the phosphate ester at from about 1% or less relative to the total composition after mixing;
e) optionally at least one oxidative dye precursor and at least one coupler or a mixture of two or more thereof;
wherein the first aqueous component (i) or the second aqueous component (ii) or both of the first aqueous component (i) and the second aqueous component (ii) comprise a gel-network system consisting of multi-lamellar sheets or vesicles or both, with d-spacing between 5 nm and 50 nm as measured by Small Angle X-Ray Scattering, and
wherein the first aqueous component (i) or the second aqueous component (ii) or both of the first aqueous component (i) and second aqueous component(ii) comprise a malodor suppressant consisting of isopropyl myristate.
