Liquid Crystals in O/W Emulsions with Urea: Development and Testing
By: O.D.H. Santos, F. Sacai, M. Ferrari and P.A. R…
Using a ternary phase diagram, the authors developed systems based on nonionic surfactants, light paraffin oil, water, and (optionally) urea. Systems in which lamellar liquid crystals formed and in which urea was an ingredient showed higher occlusive power and lower TEWL in in vitro tests.

Humectants: More Than Meets The Eye (or Skin)
By: Ken Klein, Cosmetech Laboratories
Whenever we are asked to formulate an emulsion, we think of and usually add a humectant. A humectant being defined as “a substance that promotes retention of moisture.” It is derived from Latin “hu-mecta-ns, hu-mecta-nt, present participle of hu-mecta-re, to moisten, from hu-mectus, moist, from hu-me-re, to be moist.” But these versatile materials deserve our respect. They have functions that go far beyond this simplistic definition!

Advances in Polymers for Hair Conditioning Shampoos
By: Robert Y. Lochhead and Lisa R. Huisinga, Schoo…
The dilution-deposition mechanism is the core of the modern conditioning shampoo. It is described here, along with polymer inventions that enhance benefits and improve the clarity of conditioning shampoos, and enable conditioning from shampoos that do not contain a cationic polymer.

Busy Signals Explain Itch from Dry Skin
By: Gil Yosipovitch, MD, and Kelly L. Barham, MD
This review of literature suggests that crosstalk between the stratum corneum and nerve fibers in the epidermis is the process by which itch is transmitted to the central nervous system. A rationale is presented for using moisturizers to reduce itch.
