Hair Dye Shampoo Formulation Inquiry

Regarding the hair dye shampoo formula you provided, we've reviewed the ingredients against our available products.

Based on our search:

• Cetearyl Alcohol is available and suitable as a thickener.
• A form of Hydrogen Peroxide is available (15% gel), though its suitability for a shampoo base at 2% would need careful evaluation.
• A derivative of P-paraphenylene diamine (PPD), N-Phenyl-p-phenylenediamine sulfate, which functions as a primary dye intermediate, is available.
• However, the Resorcinol specified in your formula is not available in the form used for hair dye. The products we have that contain "Resorcinol" are for skin whitening.
• Sodium sulfate is also not available, and the listed concentration (20%) appears unusually high for this type of product.

Formulating hair dye is highly complex, requiring precise ratios and specific types of chemicals for safety, stability, and desired color results. Due to the unavailability of key ingredients like the correct Resorcinol and Sodium Sulfate, and the potential safety concerns associated with hair dye chemicals, we cannot validate your formula or provide a specific alternative.

We strongly recommend that hair dye formulations be developed by or in consultation with experienced cosmetic chemists who can ensure the safety, stability, and efficacy of the final product.
