What is the optimal pH range for green tea extract to be effective and stable?
Answer
Optimal pH for Green Tea Extract Stability and Effectiveness
Based on information for green tea extracts, the recommended pH range for optimal effectiveness and stability is typically between 4.0 and 6.5.
Maintaining the formulation within this pH range helps preserve the beneficial compounds, such as EGCG, which are responsible for the antioxidant and other skin benefits of green tea extract. It is also important to store products containing green tea extract away from light and heat to maintain their quality.
