The rheology of a pre-neutralized, hydrophobically modified acrylic polymer was investigated by dynamic mechanical measurements using this methodological approach to establish its viscoelastic profile and stability in formulations. Properties of several polymer-containing emulsions were studied and their particle size distribution investigated by laser diffraction.

Informatics techniques have been developed that are capable of manipulating huge data sets that underpin modern formulation—from mining for information, to analyzing vast amounts of data. This article highlights how the use of computer technology can increase the efficiency and efficacy of formulating.

Naturally occurring and synthetic avenanthramides were evaluated for their efficacy to inhibit substance P-induced release of histamine from mast cells. In vivo tests showed that four synthetic avenanthramides demonstrated ability to significantly reduce histamine-induced itch and redness. Dihydroavenanthramide D was also shown to be an excellent antioxidant.

A preservative efficacy testing method, called accelerated double challenge, rapidly—in 14 days—assesses the ability of a product or material to resist microbial contamination. It also maintains a high degree of correlation with longer-term preservative challenge protocols.
