Definitions

• the present invention relates to a process for the oxidative coloring of hair, in which an optimal color balance between the hairline on the one hand and hair lengths and hair tips on the other hand is achieved.
• a process for the oxidative dyeing of hair based on a dye carrier mass F, which contains a developer substance-coupler substance combination and which is used after mixing with an oxidizing agent, in which a first Step the dye carrier mass F is mixed with a preparation A containing an oxidizing agent and then the mixture FA thus obtained is applied to the hairline (hair growth) and allowed to act and in a second step the dye carrier mass F is mixed with a preparation B containing an oxidizing agent and then the mixture FB thus obtained is applied to the hair lengths and hair tips and allowed to act, the preparation B having a more acidic pH than the preparation A, and finally rinsing the hair with water, optionally aftertreated and then drying, the task set being convincing is solved.
• the dye carrier composition F contains developer substances, in particular 1,4-diaminobenzene, 2,5-diamino toluene, 2,5-diaminobenzyl alcohol, 2- (2'-hydroxyethyl) -1, 4-diaminobenzene, 4-aminophenol , 4-amino-2-aminomethylphenol, 4-amino-3-methylphenol, 4-amino-2-methoxymethylphenol, 4-amino-2-ethoxymethylphenol as well as tetraaminopyridine or their physiologically compatible, water-soluble salts.
• developer substances in particular 1,4-diaminobenzene, 2,5-diamino toluene, 2,5-diaminobenzyl alcohol, 2- (2'-hydroxyethyl) -1, 4-diaminobenzene, 4-aminophenol , 4-amino-2-aminomethylphenol, 4-amino-3-methylphenol, 4-amino-2-methoxymethyl
• the developer substances and the coupler substances are contained in the dye carrier mass F in an amount of 0.01 to 8.0 percent by weight, preferably 0.02 to 4.0 percent by weight.
• the total amount of developer-coupler-substance combination contained in the dye carrier mass F described here should be about 0.01 to 12.0 percent by weight, but preferably 0.2 to 6.0 percent by weight.
• the dye carrier mass F can also contain other color components, for example the self-coupling dyes 6-amino-2-methylphenol, 2-amino5-ethoxyphenol and 2-amino-5-methylphenol and also conventional direct dyes, for example triphenylmethane dyes such as diamond Fuchsine (CI 42 510) and Leather Ruby HF (CI 42 520), aromatic nitro dyes such as 2-nitro-l, 4-diamino-benzene, 2-amino-4-nitrophenol, 2-amino-4-nitro-6 -chlorophenol, 4-amino-3-nitrotoluene.
• the self-coupling dyes 6-amino-2-methylphenol, 2-amino5-ethoxyphenol and 2-amino-5-methylphenol and also conventional direct dyes, for example triphenylmethane dyes such as
• constituents mentioned are used in the amounts customary for such purposes, for example the wetting agents and emulsifiers in concentrations of about 0.5 to 30 percent by weight, the thickeners in an amount of about 0.1 to 25 percent by weight and the care substances in one Concentration from about 0.1 to 5.0 percent by weight.
• the dye carrier mass F described above is mixed with the preparation A or B containing an oxidizing agent immediately before use, and an amount sufficient for the hair dye treatment, depending on the fullness of the hair, is generally about 60 to 200 g , this mixture according to the inventive method on the hair.
• the preparation A is adjusted to a pH of 2.3 to 5, preferably 2.3 to 4.0, while the preparation B a pH of 0.8 to 3, preferably 0.8 to 2, 5 has.
• the pH of the preparations A or B is adjusted by adding physiologically compatible organic or inorganic acids, with phosphoric acid being preferred. This can also be used in combination with primary, secondary and tertiary phosphates.
• the dye carrier mass F is mixed with the preparations A or B containing an oxidizing agent mixed in a ratio of about 4: 1 to 1: 4, with a mixing ratio of about 1: 1 being preferred.
• the pH value of the dye carrier mass F is reduced by mixing with the preparations A or B, the lowering of the pH value in connection with preparation B being greater.
• the pH of the mixtures FA and FB is between 7.5 and 13, the pH of the mixture FA being 0.5 to 1.5 higher than the pH of the mixture FB.
• the dye carrier mass F1 is mixed in a ratio of 1: 1 with the preparation A, so that the mixture FIA is formed.
• the dye carrier mass F1 is mixed in a ratio of 1: 1 with the preparation B, so that the mixture FIB is formed.
• the pH of the mixture FIA is 10.4, while the mixture FIB has a pH of 9.4.
• the FIA mixture is applied to the hairline (hair regrowth) of gold-orange colored hair 4 weeks ago and left to act at room temperature for 20 minutes. 7 minutes before the end of the exposure time of the mixture FIA, the mixture FIB is applied to the lengths and tips of the hair and allowed to act. After these 7 minutes, the mixtures FIA and FIB are rinsed out with water and the hair is dried.
• the hair has taken on a very balanced golden orange color, which has excellent stability against shampoo treatments.
• the dye carrier mass F2 is mixed in a ratio of 1: 1 with the preparation A, so that the mixture F2A is formed.
• the dye carrier mass F2 is mixed in a ratio of 1: 1 with the preparation B, so that the mixture F2B is formed.
• the pH of the mixture F2A is 10.5, while the mixture F2B has a pH of 9.5.
• the mixture F2A is applied to the Hairline (hair growth) of a hair dyed red 4 weeks ago and leaves it to act at room temperature for 30 minutes. 10 minutes before the end of the exposure time of the mixture F2A, the mixture F2B is applied to the lengths and tips of the hair and allowed to act.
