Abstract
The present invention relates to a process for preparing or selecting compositions having a fragrance burst of at least 20% relative to a product before dilution as well as enhanced deposition. The composition is selected such that perfume and surfactant in said composition yields a calculated “Perfume Burst Index” (PBI) value of less than 3 as per algorithm defining the PBI.
