Questiоn 2 Answer аll the pаrts оf the questiоn A-C You аre developing a high-performance anti-ageing emulsion containing: Niacinamide (Vitamin B3) Argan oil Cetearylalcohol Polysorbate 60 and Sorbitan stearate (emulsifier blend) Phenoxyethanol (preservative) Hyaluronic acid (sodium salt) Deionised water A) Assign each ingredient to its respective phase (A, B, or C), providing justification based on polarity, solubility, and heat sensitivity. (10 marks) B) Design a detailed formulation protocol, specifying processing parameters such as temperature range, homogenisation method, and cooling profile. Explain how each step contributes to the formation of a stable emulsion. (10 marks) C) During stability testing, the emulsion shows signs of phase separation and viscosity loss after 14 days at 40 °C. Identify two possible physicochemical causes and propose evidence-based formulation adjustments to correct these issues. (5 marks)
