We highly recommend referring to the professional guidelines set out in the Australian Pharmaceutical Formulary Handbook (currently APF26) to ensure you comply with all requirements applicable to your compounding activities. This is a valuable resource used by all compounding chemists in Australia and it is updated on a regular basis. 



To help you choose the right base for your compounding needs, check out our Summary of Bases, which includes a description of every base, its benefits and its applications.
