Personal product composition comprising a structured benefit agent composition and a delivery vehicle
European Patent EP1479365
Publication Date: Aug 31, 2011
Assignee: Unilever PLC Unilever N.V.

The present invention comprises a structured pre-mix or "delivery vehicle" composition designed to enhance delivery (e.g., via enhanced deposition) of hydrophobic benefit agent(s), for example, moisturizing oils, from personal product liquid compositions.

When the structured benefit agent composition is separately prepared and combined with the personal product composition, a personal product carrying composition is provided which yields enhanced delivery of the benefit agent(s). It should be noted that not only the benefit agent which is structured will benefit from enhanced delivery, but also benefit agents which are separately found in the composition (e.g., entrapped within a network formed by the structured benefit agent or added separately and not as part of the pre-mix) also may have enhanced delivery. The separate, not necessarily independently structured benefit agent (and certainly not structured as delivered in the invention if not added with the pre-mix) may be other hydrophobic benefit agents (e.g., perfumes, shine enhancing benefit agents, emollients) or hydrophilic benefit agents (e.g., glycerol). Hydrophobic benefit agents (e.g., oils) can provide moisturizing and/or conditioning benefits to the skin or hair. At present, however, it is extremely difficult to achieve high levels of deposition from personal product compositions, particularly wash-off products, such as personal wash liquid and bar cleansers.
