I have no idea what this "magic" ingredient is; however I do know that most (if not all) commercial fragrances will comprise of very many more components than your attempts do. The average number of ingredients in a fragrance will be in the 30s, if not more. There are exceptions of course, but generally you would expect to find that number. These ingredients will be a mixture of Essential Oils , bases and individual synthetics. Thus, each fragrance will be made of many hundreds of individual chemicals. It may be, that this special something you are trying to find is composed of complexity of ingredients together with experience of the Perfumer who created it.
It is rarely true that there is a magic something that fixes the problem.
