Composition for the oxidation dyeing of keratin fibres, comprising particular fatty alcohols, a liquid fatty substance and a cationic polymer

Composition for dyeing keratin fibres, comprising:

• one or more oxidation dyes,
• one or more basifying agents,
• one or more non-oxyalkylenated fatty substances that are liquid at room temperature, chosen from hydrocarbons containing more than 16 carbon atoms selected from the group consisting of liquid parafins, liquid petroleum jelly, polydecenes, hydrogenated polyisobutene, squalane, and mixtures thereof,
• one or more oxidizing agents,
• one or more oxyethylenated fatty alcohols with a number of oxyethylene units of greater than or equal to 10,
• one or more oxyethylenated fatty alcohols with a number of oxyethylene units of less than 10;
• one or more non-oxyethylenated fatty alcohols that are solid at room temperature, and
• one or more cationic polymers,
• the content of one or more non-oxyalkylenated fatty substances that are liquid at room temperature ranging from 1% to 10% by weight relative to the total weight of the composition.
