Function in Hair Dyeing:
Sodium Sulphite is an antioxidant and reducing agent commonly used in hair dye formulations.
It helps prevent the oxidation of the dye components before they are applied to the hair.
Role in Stability and Performance:
By acting as an antioxidant, Sodium Sulphite ensures that the hair dye ingredients do not
prematurely react with air or other environmental factors, which would render the product
ineffective. This increases the stability of the formulation and guarantees consistent results
when the product is used.
Common Usage:
Sodium Sulphite is widely used in both permanent and semi-permanent hair dyes to maintain
the dye’s potency. It is particularly important in formulations that require stability for long
periods, such as in pre-mixed hair dye kits.
