wherein the effective amount of the at least one chelating agent ranges from 4.36% to 17.08% by weight based on the total weight of the composition, and
wherein the at least one chelating agent is a mixture of at least one salt of etidronic acid and at least one salt of diethylenetriamine pentaacetic acid, the molar ratio of the at least one salt of etidronic acid to the at least one salt of diethylenetriamine pentaacetic acid ranging from 3:1 to 1.2:1.
2. The composition according to claim 1 , wherein the composition comprises at least one hair strengthener, and/or at least one free radical scavenger.
3. The composition according to claim 1 , wherein the composition is a cosmetic composition.
4. The composition according to claim 1 , wherein the composition is a hair cosmetic composition.
5. A composition, the composition comprising:
a cosmetically effective amount of at least one chelating agent dissolved in a water-based medium, suitable for chelating cationic transition metals in an oxidation alkali medium;
at least one hair oxidative dyeing or bleaching agent; and
at least one oxidant,
wherein the composition is a ready-to-use hair dyeing and/or bleaching composition having an alkaline pH,
wherein the total molar concentration of the at least one chelating agent in the composition ranges from 4.6 mM to 18 mM, and
wherein the chelating agent is a mixture of at least one salt of etidronic acid and at least one salt of diethylenetriamine pentaacetic acid, the molar ratio of the at least one salt of etidronic acid to the at least one salt of diethylenetriamine pentaacetic acid ranging from 3:1 to 1.2:1.
6. The composition according to claim 1 , wherein the composition is a part of a kit for dyeing and/or bleaching hair, wherein the composition is individually packaged and the kit further comprises an individually packaged hair dyeing and/or bleaching composition comprising at least one hair oxidative dyeing or bleaching agent, and an individually packaged oxidizing composition comprising at least one oxidant.
7. The composition according to claim 1 , wherein the composition is used for decreasing and/or preventing color deviation in the hair, and/or chromaticity deviation, and/or hair damage provoked by a ready-to-use hair dyeing, and/or bleaching composition comprising at least one oxidant.
8. The composition according to claim 5 , wherein the composition is applied to the hair, and wherein the hair is rinsed with water after an application time of the ready-to-use hair dyeing and/or bleaching composition in the hair from 1 minute to 1 hour.
9. A method for dyeing and/or bleaching hair, the method comprising:
a) applying to the hair a composition having an alkaline pH and comprising an effective amount of at least one chelating agent, suitable for chelating cationic transition metals in an oxidation alkali medium,
wherein the effective amount of the at least one chelating agent ranges from 4.36% to 17.08% by weight based on the total weight of the composition, and
wherein the chelating agent is a mixture of at least one salt of etidronic acid and at least one salt of diethylenetriamine pentaacetic acid, the molar ratio of the at least one salt of etidronic acid to the at least one salt of diethylenetriamine pentaacetic acid ranging from 3:1 to 1.2:1;
b) optionally rinsing the hair;
c) optionally drying the hair; and
d) applying a ready-to-use hair dyeing and/or bleaching composition comprising at least one hair oxidative dyeing or bleaching agent, and at least one oxidant, and rinsing the hair with water after an application time of the ready-to-use hair dyeing and/or bleaching composition in the hair from 1 minute to 1 hour.
10. The method of claim 9 , the method further comprising at least one treatment step with at least one hair care product selected from the group of shampoos, conditioners, masks, sprays, oils and/or serums.
11. The composition according to claim 8 , and wherein the hair is treated with at least one treatment step with at least one hair care product selected from the group of shampoos, conditioners, masks, sprays, oils and/or serums.
12. A method for dyeing and/or bleaching hair, the method comprising:
applying to the hair a composition comprising:
a cosmetically effective amount of at least one chelating agent dissolved in a water-based medium, suitable for chelating cationic transition metals in an oxidation alkali medium; at least one hair oxidative dyeing or bleaching agent; and
at least one oxidant,
wherein the composition is a ready-to-use hair dyeing and/or bleaching composition having an alkaline pH;
wherein the total molar concentration of the at least one chelating agent in the ready-to-use composition ranges from 4.6 mM to 18 mM; and
wherein the chelating agent is a mixture of at least one salt of etidronic acid and at least one salt of diethylenetriamine pentaacetic acid, the molar ratio of the at least one salt of etidronic acid to the at least one salt of diethylenetriamine pentaacetic acid ranging from 3:1 to 1.2:1; and
rinsing the hair with water after an application time of the ready-to-use hair dyeing and/or bleaching composition in the hair from 1 minute to 1 hour.
