Ingredients for Stabilizing Hydrogen Peroxide in Hair Dye Shampoo

To help stabilize hydrogen peroxide in hair dye shampoo formulations and prevent quality degradation when exposed to air, you can consider using ingredients known for this purpose.

Based on common usage in hair coloring products, two ingredients that function as hair dye stabilizers are:

• PMP (3-Methyl-1-phenyl-5-pyrazolone): This ingredient is used in permanent hair dye products specifically to increase stability.
• Thioglycerin (Glycerol Monothioglycolate): While also known for breaking disulfide bonds in hair for perming and color penetration, it is also listed as a hair dye stabilizer to maintain product quality.

These ingredients help ensure the hydrogen peroxide remains effective and the product maintains its quality over time.
