1. Personal wash composition comprising (1) 0% to 99% by wt. of a surfactant material selected from the group consisting of anionic, nonionic, amphoteric, cationic surfactants and mixtures thereof;
- and (2) 0.1 to 90% of structured benefit agent composition comprising;
(a) 0.1 to 99.9% by wt. of structured benefit agent composition of one or more benefit agents or mixtures thereof;
(b) 99.9 to 0.1% of structured benefit agent of structuring material selected from the group consisting of natural or synthetic waxes natural or synthetic hydrogenated oils or fats, fatty acids, fatty alcohols, salts of fatty acids, hydroxy fatty acids, fatty acid esters, and mixtures thereof, wherein the crystal in said structuring material has an aspect ratio defined by A/B>
1, the length A being understood as the longer of the two dimensions when considering length and width, B; and
(3) separate hydrophobic benefit agent, wherein, when said structured benefit agent composition is separately formed and separately combined with a carrying composition in which the structured benefit agent carrier will be used to deliver said benefit agent to a substrate there is provided enhanced benefit of the separate hydrophobic benefit agent if at least 5% relative to the effect provided by the same separate hydrophobic benefit agent in the absence of structured benefit agent in the final composition.

Abstract
The present invention comprises a structured premix or “delivery vehicle” composition designed as a carrier to enhance the benefit (e.g., via enhanced deposition or other mechanism) of a separate hydrophobic benefit agent(s) (for example, perfumes, skin lightening agents, etc.), from personal product compositions (e.g., liquid and bar cleansers, creams, emulsions, hair composition, deodorant etc.). When the structured benefit agent composition is separately prepared and combined with the personal product composition (preferably while structured, premix composition is still in molten or liquid state), the personal product composition with structured benefit agent carrier provides enhanced deposition of the structured benefit agent and enhanced effect of the separate hydrophobic benefit agent(s) in or on the carrier or in the presence of structured benefit agent carrier.
