Present invention relates to an aqueous oxidizing composition for hair which makes possible achieving homogeneous coloration of multiple damaged hair and especially provides excellent grey coverage with oxidative hair dyes. The object of the invention is an aqueous oxidizing composition for hair comprising one or more oxidizing agent, one or more polyol, one or more oil, one or more solid fatty alcohol and one or more surfactant wherein fatty alcohol to oil weight ratio is less than 1, weight ratio of surfactant to sum of fatty alcohol and oil is less than 0.25 and polyol concentration is less than or equal to 2% by weight calculated to the total of the composition.

Aqueous oxidizing composition for hair

Present invention relates to a process for manufacturing emulsion composition which comprises an oil phase dispersed in a continuous water phase which is stabilized with a surfactant as an emulsifier. The present invention is on a method for producing an emulsion comprising one or more fatty alcohol, one or more oil liquid at 20&#xb0; C. and one or more surfactant wherein one or more surfactant is added to the dispersion of one or more fatty alcohol and one or more oil liquid at 20&#xb0; C. in water at a temperature of 50&#xb0; C. or higher, preferably 60&#xb0; C. or higher with the condition that the temperature of the dispersion is at least 10&#xb0; C. higher than the melting point of fatty alcohol having the highest melting point, more preferably between 60 and 85&#xb0; C. wherein the emulsion thus obtained does not comprise dispersed droplets with a volume size larger than or equal to 10 &#x3bc;m measured directly without dilution of the emulsion at 20&#xb0; C. measured with a laser particle size analyzer suitable therefore.
