"Milking" Plants for Sustainable, Pure Extraction

Plant Advanced Technologies has developed a process to "milk" plants in order to obtain active and natural extracts without damaging the plants.

Comparatively Speaking: Density vs. Specific Gravity

This edition of "Comparatively Speaking" by industry expert Tony O'Lenick compares a product's density with its specific gravity, which are important measurements for formulators to understand especially when considering product specifications.

Traditional Microscope Gets a 3-D Upgrade

Researchers at Ohio State University have invented a single lens that enables microscopic objects to be viewed from nine angles at once to create a 3-D image.

Eco-friendly Equipment Cleaner

Ecover Belgium NV has introduced an ecological, all-purpose cleaner suitable for cleaning the appliances and machinery used to manufacture food and cosmetics.

Syntopix Backed in Microemulsion Surfactant Challenge

Syntopix Group Plc has secured backing from Intelligent Formulation Ltd. for a 30-day international research challenge. Over the month-long project, Syntopix will work with world experts to characterize microemulsions made from environmentally friendly surfactants, especially those used to make skin care.

Comparatively Speaking: Refractive Index vs. Refraction of Light

Tony O'Lenick explains the difference between the refractive index and refraction of light to produce color. These terms can be used by the formulator to produce transparent emulsions and predict the color of emulsions, respectively.

Comparatively Speaking: GLC vs. GPC

Tony O'Lenick explains the difference between two types of chromatography: gas liquid chromatography (GLC) and gel permeation chromatography (GPC), both used to separate compounds in mixtures.

Comparatively Speaking: Density vs. Specific Gravity

Formulators often are faced with product specifications for which the tests are not chemical but physical. Oftentimes, the terms describing these physical traits are not clearly defined. Two such terms are density and specific gravity.

Peer Review and Scientific Journals: A Debate

"How do you feel about peer review in scientific journals?" Rachel Grabenhofer, editor of Cosmetics & Toiletries magazine, recently asked. Here's how readers responded.

Comparatively Speaking: Green vs. Greening Cosmetic Formulations

Tony O'Lenick explains the difference between 'green' cosmetic formulations and 'greening' cosmetic formulations, and introduces the concept of the Green Star Rating.
