Mustapha H.

Cosmetic Chemist & Product Formulator

I help founders and brands develop high-performing formulas that are stable, scalable, and ready for manufacturing. You get clean documentation, practical ingredient choices, and a process that protects your timeline and budget. Projects start at £500 for a paper formula + method (includes 2 revisions). £1500+ includes lab sampling/prototype support. What I can formulate: • Skincare, haircare, and body care: serums, moisturisers, cleansers, toners, oils, balms, body lotions, body washes, deodorants, scalp serums, shampoos, conditioners, masks, leave-ins • Performance targets: barrier repair, hydration, brightening, anti-ageing, acne support, scalp comfort, frizz control, curl definition, body smoothing • Natural-origin focused formulas (including 95%+ where feasible) and performance-led synthetic systems What you receive: • Formula (INCI + percentages) plus manufacturing method • Raw material function rationale plus substitution guidance • pH and viscosity targets, stability considerations, and scale-up notes • Optional sample or lab batching support depending on scope How I work: 1. Brief and constraints (claims, market, region, budget, texture, packaging) 2. Prototype strategy (1–2 directions) 3. Delivery of formula + method + iteration based on feedback I’m direct, quick to communicate with, and focused on formulas that manufacture cleanly and perform as promised.
