Hydrolysis-Resistant Esters
By: John A. Imperante, Phoenix Chemical
Hydrolytic instability of esters in cosmetic products can be reduced, compared to that of standard straight chain esters, by using non-hydrolyzable esters synthesized from a diol reaction sequence. Two commercial dimer diol di-esters, given as examples, enable stable formulations at extremes of pH.

A Hydrophobically Modified Inulin Surfactant for Preparing and Stabilizing Nanoemulsions
By: T. Tadros, Consultant; E. Vandekerckhove, A. …
Nanoemulsions prepared and stabilized with hydrophobically modified inulin as the surfactant require much less surfactant than nanoemulsions prepared and stabilized using conventional surfactants such as alcohol ethoxylate because they have a reduced Ostwald ripening rate.

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!

Anti-dandruff Efficacy of Sodium Shale Oil Sulfonate Versus Coal Tar
By: Guido Gayko, PhD, Jürgen Warnecke, MD and Clau…
Coal tar is an effective antidandruff active, but it contains compounds that are proven carcinogens. In this article sodium shale oil sulfonate is shown in preliminary results for the first time to have antidandruff efficacy equivalent to that of coal tar with none of coal tar’s toxic potential.
