Cosmetics Formulation Development

Is there any ready-made base that I can add this ingredient to and use? And if I use ready-made base, do I need to use additional preservatives, activeprotecox, activeprotecox? Or if there is no ready-made base that can be mixed? Please help recommend mixing methods and binders. Thank you.
