This product can cause pH drift and is therefore not recommended for inexperienced formulators. It is important to ensure that your formulation has a final pH between 3 and 6 (5.2 - 5.5 recommended). Please refer to the attached product specification for a fuller explanation, in particular section 9 on formulation. Aesthetic problems that can result from incompatible pH can include crystaline deposits of sodium benzoate or waxy deposits where constituent ingredients 'drop out' depending on the product formulation. Where these become evident it is generally only aesthetic rather then the preservative being ineffective.
