Structured Surfactant Systems for Deposition of Perfume on Skin and Hair

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.

Water-soluble Phosphate Polymers in Bar Soap for Controlled Release of Antimicrobial Silver

This paper presents data on the antimicrobial performance of a silver ion-releasing phosphate polymer incorporated into a bar soap product. Two studies test the speed, efficacy and longevity of the antimicrobial effect, highlighting the potential of these materials for the controlled, sustained release of bioactive metal ions in cosmetic products.

Ingredient Delivery and Efficacy

Binding is not a new phenomenon, but interest in it continues for improved ingredient delivery and efficacy.

Wise Words from the Bench with Jean-Jaques Étienne, PhD

Some might consider olfaction solely the job of perfumers, but Jean-Jaques Étienne, PhD, believes it to be the job of perfumers as well as formulators.

Compass—Taking Action

There sure is a lot of activity around actives—from regulatory scrutiny over functional product claims, to ingredient research, development, optimization and efficacy testing.

How the ‘Stuff’ in Formulations Impacts the Delivery of Actives

Formulations contain many ingredients that are vital for some important function, such as providing stability. 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.

Bar Soap Containing Water-soluble Phosphate Polymers for Controlled Release of Antimicrobial Silver and Other Bioactive Metal Ions

This paper presents data on the antimicrobial performance of a silver ion-releasing phosphate polymer incorporated into a bar soap product. Two studies test the speed, efficacy and longevity of the antimicrobial effect, highlighting the potential of these materials for the controlled, sustained release of bioactive metal ions in cosmetic products.

Energizing and Invigorating Formulations With Caffeine Spheres

Pelletech has introduced cellulose-based beads loaded with 30% caffeine for energizing and invigorating personal care products.

Compass—Ties That Bind

Binding is not a new phenomenon, but interest in it continues for improved ingredient delivery and efficacy.

Saccharide Isomerate to Deeply Hydrate Skin and Scalp

Saccharide isomerate, designed to closely resemble a carbohydrate complex found in human stratum corneum, is shown here to provide up to 72 hr of deep hydration to skin and, for the first time, rinse-off soothing to the scalp. Its unique binding mechanism to skin and scalp create new opportunities for leave-on and rinse-off products.

Soy-based Binder, Thickener and Emulsifier for Personal Care

DuPont has launched a soy-based multifunctional polymer for a variety of personal care applications from sun care to hair care.
