Hi

I want to use combination of Benzyl alcohol & Phenoxyethanol as preservatives for my new body lotion. Can any one tell me how much percentage of these preservatives should be used? When I should add these preservatives in formulation? should I add in water phase before heating or should I add in cool down phase? Comments will be really appreciated
