Oxidation Hair Dyes, classified under Type-3 as per IS 8481:2020, are permanent hair coloring products that are supplied in liquid, gel, or cream forms. These dyes work through a chemical reaction between primary intermediates and couplers in the presence of an oxidizing agent (usually hydrogen peroxide), resulting in long-lasting color that penetrates the hair shaft.
These formulations typically include:
Primary intermediates (e.g., para-phenylenediamine or its derivatives)
Couplers for color modulation
Emulsifying and conditioning bases for application ease and hair care
Fragrances, stabilizers, and pH adjusters
The product must be:
Homogeneous, stable, and easy to apply
Safe for use on hair and scalp with appropriate allergen warnings
Testing of Type-3 Oxidation Hair Dyes under IS 8481:2020 ensures chemical safety, performance reliability, and regulatory compliance, as these are products involving direct skin and scalp contact with active dye intermediates.
Confirm the presence and concentration of permitted dye intermediates and couplers
Verify pH value for scalp and hair compatibility
Check for heavy metals such as lead, arsenic, and mercury to ensure non-toxicity
Assess microbial safety (absence of harmful pathogens and total viable count)
Evaluate product stability over shelf life (including phase separation or degradation)
Ensure the absence of prohibited substances such as barium salts, coal tar dyes (if applicable), etc.
Verify allergen labeling and warning declarations (e.g., patch test advisory)
Ensure packaging and labeling comply with BIS and cosmetic regulations
