Formulation view Water-alcohol vehicle loaded with hydroquinone, glycolic acid, and kojic acid for potent lightening and exfoliation. Sulfites stabilize against oxidation. Alcohol causes drying; potent actives limit usage to non-sensitive skin overnight. Formulator's note: High irritation potential due to acidic pH and alcohol; strict regulatory compliance required for hydroquinone concentration; avoid for sensitive types.

Ingredients explained
- Hydroquinone
- Melanin inhibitor restricted in EU cosmetics; primarily industrial or intermediate use; strict compliance required
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Alcohol Denatured
- Denatured alcohol for solvency and penetration; causes dryness, use caution in sensitive skin.
- Glycolic Acid
- Glycolic acid for exfoliation; requires buffering at concentrations >10%, avoid combination with other acids.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Kojic Acid
- Tyrosinase inhibitor for whitening; EU limit 1% in water, unstable and requires light protection, potential irritation.
- Sodium Bisulfite
- Reducing agent and preservative in hair waving/straightening; irritating; restricted use
- Polyquaternium-10
- Cationic polymer for fabric or hair smoothness; generally low irritation but may conflict with other cationic actives
- BHT
- Lipophilic antioxidant at 0.01-0.05%; ineffective with acidic systems, label-sensitive, check regulatory limits as preservative alternative.
- Sodium Sulfite
- Sulfite antioxidant to prevent oxidation; sulfites are known allergens and must be strictly declared on labels.
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
