AI Technical Summary
Existing hair dye products are prone to oxidation and degradation during storage, resulting in poor storage stability, low dyeing reaction efficiency, and poor color fixation, leading to loss of effective ingredients and short-lasting color.
This hair dye employs an antioxidant layered structure, using emulsifiers and cetearyl alcohol to construct a stable layered emulsion system. It combines ascorbic acid, sodium sulfite, and chelating agents to inhibit oxidation reactions, and adds humectants and pH adjusters to improve spreadability and penetration during dyeing. Vacuum homogenization is used to enhance structural stability.
It improves the storage stability and dyeing efficiency of hair dye, enhances the color-fixing effect of dye, prolongs the color durability, and reduces ineffective oxidation side reactions.
