Comparatively Speaking: Homopolymer vs. Periodic vs. Statistical Copolymers

Tony O'Lenick discusses the differences between types of copolymers including: homopolymer, periodic (block) and statistical (random) and grafted.

Comparatively Speaking: Linear vs. Branched vs. Dendrimer Polymer Structures

Industry expert Tony O'Lenick explains the difference between polymer structures, the simplest being a linear chain with a single backbone, then increasing in complexity with one or more side chains or branches. Special types of branched polymers include dendrimers.

Comparatively Speaking: Cofactors vs. Coenzymes

Enzymes for DNA repair or Coenzyme Q10 for antioxidant and antiaging benefits have become typical ingredients in today's skin care. Here, industry expert O'Lenick illustrates the difference between cofactors and coenzymes.

Comparatively Speaking: Emulsion vs. Colloid

Industry expert Anthony O'Lenick, Jr., explains the different between an emulsion and a colloid.

Comparatively Speaking: Fatty Acids vs. Ozone Acids

Industry expert Tony O'Lenick describes the differences between the formation of fatty acids by saponification followed by acidulation, and ozone acid by the reaction of unsaturated acids with ozone.

Strong, Self-healing Hydrogel Created for Tissue Engineering

Researchers from the University of Tokyo have created a strong, self-healing hydrogel with applications in tissue engineering and drug delivery. The material incorporates a binder made from long chains of polyethylene glycol, an ingredient commonly used in skin care.

Comparatively Speaking: Proteins vs. DNA vs. Sugars

Industry expert Tony O'Lenick discusses the structural differences between the biopolymers DNA, sugars and proteins, which are all important to life but function differently in the cell and in cosmetic products.
