Oxidant Hair Developer Formulation

I want to bring a professional-grade oxidant cream (hair developer) to market and need a cosmetic chemist who can create a complete, ready-for-production formula. The goal is a smooth, stable cream that mixes cleanly with oxidative colour and powder lighteners, is gentle on the scalp, and maintains potency throughout its shelf life.

Right now I’m open on final peroxide strength, so please design a base formula that can be adapted to standard 3 %, 6 % and 9 % versions without reformulating from scratch. I will supply brand positioning and packaging specs; what I need from you is the chemistry.

Deliverables
• Full ingredient list (INCI names) with exact percentages
• Recommended suppliers and grades for each raw material
• Step-by-step manufacturing procedure with critical control points
• Target specs for pH, viscosity and stability
• Basic preservative efficacy and accelerated stability test plan

Acceptance will be based on bench-scale batches meeting the target specs and showing no phase separation or loss of active peroxide during accelerated testing.

If you have experience formulating peroxide creams, especially for salon use, I’d love to see your approach and timeline.
