- Claim:
2. The blonding agent according to claim 1 , wherein sodium percarbonate is present in an amount of from about 1-50% by weight.
- Claim:
3. The blonding agent according to claim 1 , further comprises at least one inorganic salt of peroxosulfuric acid and wherein the at least one inorganic salt of a peroxosulfuric acid is selected from sodium peroxodisulfate, potassium peroxodisulfate, ammonium peroxodisulfate, sodium peroxomonosulfate, potassium peroxomonosulfate, ammonium peroxomonosulfate, or mixtures of these compounds.
- Claim:
4. The blonding agent according to claim 3 , wherein the inorganic salt of a peroxosulfuric acid includes a mixture comprising from about 5 to about 40% by weight of ammonium peroxodisulfate based on the total weight of the blonding agent.
- Claim:
5. The blonding agent according to claim 1 , further comprising a persulfate, wherein the percarbonate and the persulfate(s) are present separately from one another.
- Claim:
6. The blonding agent according to claim 5 , wherein the weight ratio of the amount of percarbonate to the total amount of persulfate(s) is between about 2 to about 1 and about 1 to about 20.
- Claim:
7. The blonding agent according to claim 1 , wherein further comprising at least one inorganic alkalizing agent solid at 20° C. and 1013 mbar, wherein the at least one inorganic alkalizing agent is chosen from sodium silicate or sodium metasilicate having a molar SiO 2 /Na 2 O ratio of ≥2.
- Claim:
8. The blonding agent according to claim 1 , further comprising at least one complexing agent selected from: ethylenediaminetetraacetic acid (EDTA); N-hydroxyethylethylenediaminetriacetic acid; aminotrimethylenephosphonic acid; diethylenetriaminepentaacetic acid; lauroyl ethylenediamine triacetic acid; nitrilotriacetic acid; iminodisuccinic acid; N-2-hydroxyethyliminodiacetic acid; ethylene glycol-bis-(beta-aminoethyl ether)-N,N-tetraacetic acid; aminotrimethylenephosphonic acid, pentasodium aminotrimethylenephosphonate, and mixtures thereof, in a total amount of from about 0.1-1.4% by weight based on the weight of the blonding agent.
- Claim:
9. The blonding agent according to claim 1 , wherein sodium percarbonate is present in an amount of from about 4-10% by weight based on the weight of the blonding agent.
- Claim:
10. The blonding agent according to claim 3 , wherein the at least one inorganic salt of a peroxosulfuric acid is included in the blonding agent in an amount of from about 30-50% by weight based on the weight of the blonding agent.
- Claim:
11. The blonding agent according to claim 3 , wherein the inorganic salt of a peroxosulfuric acid constitutes a mixture comprising from about 15 to about 30% by weight of potassium peroxodisulfate, from about 10 to about 15% by weight of ammonium peroxodisulfate, and from about 2 to about 20% by weight of sodium peroxodisulfate, in each case based on the total weight of the blonding agent.
- Claim:
12. The blonding agent according to claim 5 , wherein the weight ratio of the amount of percarbonate to the total amount of persulfate(s) is between about 1 to 3 and about 1 to 6.
- Claim:
13. The blonding agent according to claim 7 , wherein the at least one inorganic alkalizing agent is present in an amount of from about 5 to about 40% by weight based on the weight of the blonding agent.
- Claim:
14. The blonding agent according to claim 8 , wherein the at least one complexing agent is present in a total amount of from about 0.5-1.4% by weight based on the weight of the blonding agent.
- Claim:
15. A method for lightening keratinic fibers, wherein a blonding agent according to claim 1 is mixed with water, applied immediately afterwards to the keratin-containing fibers, left on the fibers for from about 5 to about 60 minutes and then the fibers are rinsed with water and optionally washed with a surfactant-containing detergent.
- Claim:
16. The blonding agent according to claim 1 , free from hydrogen peroxide.
