Dye composition having a low content of ammonia

An aerosol device comprising a means of generating, in foam form, a composition for dyeing keratin fibers comprising:

• (a) at least one amphoteric surfactant having a concentration of at least 0.5% by weight relative to the total weight of the composition;
• (b) at least one organic alkaline agent;
• (c) at least one oxidizing agent;
• (d) at least one oxidation dye precursor;
• (e) an amount of ammonia of less than 1.5% by weight relative to the total weight of the composition;
• and
• (f) at least one cationic polymer.

A nonaerosol device comprising:

• (1) a composition for dyeing keratin fibers comprising
• (a) at least one amphoteric surfactant having a concentration of at least 0.5% by weight relative to the total weight of the composition,
• (b) at least one organic alkaline agent,
• (c) at least one oxidizing agent,
• (d) at least one oxidation dye precursor,
• (e) an amount of ammonia of less than 1.5% by weight relative to the total weight of the composition, and
• (f) at least one cationic polymer;
• (2) a bottle equipped with a mechanical pumping system;
• and
• (3) a dispensing system enabling the composition to be delivered in foam form.

A process for dyeing human keratin fibers, said process comprising applying a composition comprising:

• (a) at least one amphoteric surfactant having a concentration of at least 0.5% by weight relative to the total weight of the composition,
• (b) at least one organic alkaline agent,
• (c) at least one oxidizing agent,
• (d) at least one oxidation dye precursor,
• (e) an amount of ammonia of less than 1.5% by weight relative to the total weight of the composition, and
• (f) at least one cationic polymer
• to wet or dry human keratin fibers for a period of time sufficient to develop a desired coloration.
