Hi, I’m an experienced cosmetic formulation chemist with hands-on expertise in BTMS-based conditioning systems, hair masks, and emulsion stabilization. I can review your current V3 formula, identify the root cause of the emulsion failure, and optimize both the formulation and manufacturing process for consistent, production-ready results. My deliverables will include an optimized formula with corrected percentages (if required), detailed step-by-step production instructions, equipment recommendations, pH and preservation verification, a complete INCI ingredient list, and clear notes for co-manufacturer handoff. I have worked on similar rinse-off hair care formulations involving conditioning emulsions, proteins, botanical actives, and high oil-phase systems. I’d be happy to review your formula PDF and discuss the best path to achieving a stable, scalable product. Best regards, SJ

Hello, I am a cosmetic formulation chemist with 8+ years of experience in rinse‑off hair care emulsions, including BTMS‑based systems. Based on your formula, the emulsion break is likely caused by insufficient high‑shear mixing during the oil‑water combination, mismatched cool‑down addition order, or the high oil phase (≈40%) relative to the emulsifier level. I will review your full formula, identify the root cause, and provide an optimized version (adjusting emulsifier ratios, oil phase percentage, or processing steps). I will deliver a production‑ready document including: corrected ingredient percentages (INCI‑ready), step‑by‑step kitchen and co‑manufacturer instructions (with temperatures, mixing speeds, and hold times), equipment requirements, pH target and preservation verification (including recommendations for stability testing). I have experience with similar conditioning masks and can share examples of past formula optimizations. Best regards.
