Structured Surfactant Systems for Deposition of Perfume on Skin and Hair
By: Caroline Mabille, PhD, Rhodia Aubervilliers Re…
To maximize perfume delivery from structured cleansing formulations, the fragrance must be introduced before structuring the formulation into multilamellar vesicles. Structured formulations fragranced in such a way are shown here to improve perfume deposition and duration versus micellar systems, with no negative impact on perfume burst during use.

How the ‘Stuff’ in Formulations Impacts the Delivery of Actives
By: Steven Abbott, PhD, Steven Abbott TCNF Ltd. an…

However, what does this “stuff” do in terms of helping or (usually) hindering the delivery of the all-important active? And how much of the active is actually available to deliver? A few simple questions and measurements, described here, can provide a wealth of insight.
