It depends, but typically not exactly. Creating an “exact” match means duplicating all the same ingredients at the same addition rates in a fragrance. Fragrance recipes are complicated typically containing many ingredients, some at minute levels (<0.1%). Our fragrance duplications are often 90-95% “exact” and work very well when compared in the finished product. Note: it is important to always test fragrances matches side-by-side in the finished product, and not as supplied. When required, analytical evaluation of ingredients can be done.
