Comparatively Speaking: Essential Fatty Acid vs. Trans Fatty Acid

Tony O'Lenick explains the difference between essential fatty acids, which occur in nature, and trans fatty acids, which are synthesized. In addition, while essential fatty acids are often found in skin care, trans fatty acids are not.

Comparatively Speaking: Liquid, Soft and Dry Extracts vs. Tinctures

In the following excerpt, Tony O'Lenick looks to Tony Dweck to explain the difference between liquid, soft and dry extracts and tinctures.

Comparatively Speaking: Naturally Occurring vs. Naturally Derived vs. Chemically Modified Butters

Tony O'Lenick explains the difference between naturally occurring, naturally derived and chemically modified butters since some butters possess better cosmetic properties, which is of use to the formulator.

Comparatively Speaking: Singlet vs. Triplet State of UV Filters

In this discussion, Tony O'Lenick looks to Craig Bonda to explain the photochemical differences between the singlet and triplet states of UV filters. These differences are important to the formulator, as their chemical reactions can lead to the destruction of sunscreens.

Comparatively Speaking: Precision vs. Accuracy in Formulating

Tony O'Lenick explains the difference between precision and accuracy as it relates to formulating; for instance, in the case of raw material consistencies between batches.

Amphiphilic Silicones to Extract Botanical Actives

Silicone-based compounds enable chemists to extract the desired fractions of materials from plants as well as impart cosmetic aesthetics. Here the authors discuss how to extract actives using amphiphilic silicones that have different partition coefficients, which are obtained by altering the ratio of oil-, water- and fluoro-soluble groups on the silicone molecule.

Comparatively Speaking: Adsorption vs. Absorption

Tony O’Lenick explains the difference between absorption and adsorption for the benefit of novice formulators.

Comparatively Speaking: Fatty Alcohols vs. Fatty Acids vs. Esters

In the present discussion of fatty alcohols, fatty acids and esters, Tony O’Lenick recruits Ismail Walele of Phoenix Chemical to explain the differences between them.

Comparatively Speaking: Traditional vs. Non-traditional Natural Oils

Industry expert Tony O'Lenick discusses the differences between the structures of traditional natural oils and non-traditional natural oils.

Comparatively Speaking: Natural Oils vs. Man-made Glyceryl Esters

Industry expert Tony O'Lenick compares natural oils with man-made glyceryl esters, noting that natural oils are made by living systems using enzymes and are currently an attractive option for their sustainability.

Comparatively Speaking: Types of Flow Behavior

The following excerpt is adapted from an article by Kelly Dobos of Kao Corp. that discusses fluid viscosity of cosmetic products, specifically types of flow behavior, which can be used by the formulator to determine the rheological properties of formulations.

Comparatively Speaking: Alkoxylation vs. Ethenification

Industry expert Tony O'Lenick discusses the difference between alkoxylation and ethenification; for one, while the two are related, ethenification uses an ester as the reactant rather than alcohol.
