Ingredient Availability and Antioxidants in Hair Color Formulations

Here is information regarding the availability of the ingredients you listed and the use of antioxidants in hair color formulations:

Ingredient Availability:

• Tetrasodium Pyrophosphate: Available as Tetrasodium Pyrophosphate (TSPP).
• Disodium Phosphate: A product with the exact name Disodium Phosphate was not found in our search. However, Disodium Phosphate is listed as a Hydrogen Peroxide Stabilizer in example hair developer formulas.
• Phosphoric Acid: A product with the exact name Phosphoric Acid was not found in our search. Phosphoric Acid is also listed as a Hydrogen Peroxide Stabilizer in example hair developer formulas.
• Sodium Stannate: Available as Sodium Stannate (Trihydrate).
• Active Protex OX: Available as ActiveProtec™ OX.
• Ascorbic Acid: Available in several grades, including Vitamin C (L-ascorbic acid) (Ultra-Fine), Vitamin C (L-ascorbic acid) (Fine), and Vitamin C (L-ascorbic acid) (Standard).
• PPD (p-Phenylenediamine): A derivative, N-Phenyl-p-phenylenediamine sulfate (4ADS), is available and functions as a primary oxidation base in hair dyes.
• DPE (Diaminophenol HCl): Available as DPE (2,4-Diaminophenoxyethanol HCl) (Coupler / Secondary).
• MAP (m-Aminophenol): A product with the exact name m-Aminophenol was not found in our search.
• RL (Resorcinol): A product with the exact name Resorcinol was not found in our search, although related compounds are available. Resorcinol is listed as a coupler in hair dye formulations.

Antioxidants in Hair Colorants:

Yes, ActiveProtec™ OX and Ascorbic Acid are suitable for use as antioxidants in hair colorant formulations. ActiveProtec™ OX is designed to prevent oxidation and discoloration in various formulations, including those containing Vitamin C and other ingredients used in hair products. Ascorbic Acid is also a common antioxidant in hair dye systems.

An example hair coloring formula shows the use of Ascorbic Acid at 0.5% and ActiveProtec™ OX at 1%. These concentrations are typical for providing antioxidant protection in formulations containing oxidative dyes and couplers like the ones you mentioned (PPD, DPE, MAP, RL). The specific required amount can vary depending on the complete formula composition and desired stability, but these percentages provide a good starting point and are generally considered sufficient for this purpose.
