In the present article, microchannel emulsification is explored as a process method that precisely adds a dispersed phase into a continuous phase through an engineered dispersion plate. This approach is shown to produce emulsions with smaller droplets having tighter size distributions than conventional means, which leads to stable products with the limited need, if any, for surfactants.

Hydrolyzed jojoba esters were incorporated into formulas including a lotion, hand sanitizer and nonwoven wipes. Small, well-controlled clinical studies were then conducted to compare the formulas with or without glycerin. Results show the esters can potentiate the skin moisturizing effect of glycerin under varying formula conditions. A mechanism of action also is discussed.

This study examines the photostability of retinol and retinyl palmitate, finding they break down rapidly when exposed to UV radiation in the 290–400 nm range. This severely reduces their concentrations in finished formulations. However, when combined with ethylhexyl methoxycrylene, these retinoids are shown to be protected against photodegradation, thus preserving their concentrations both during the manufacturing process and following application to the skin.
