|The aim of this study was to develop a hydrophilic oral controlled release system (CRS) using the amorphous form of gliclazide, a BCS class II compound, listed on the WHO list of essential medicines. For this purpose, spray-dried dispersions (SDDs) of gliclazide were produced using various grades of hydroxypropyl methylcellulose acetate succinate (HPMCAS) or copovidone as carrier under fully automated conditions||Lu, Zheng, Yonglai Yang, Rae-Ann Covington, Yunxia Vivian Bi, Thomas Dürig, and Reza Fassihi||polysaccharides, acetylenics||life sciences|
Cigarette smoke was used to simulate a polluted environment and an experiment was performed to reveal how virgin and bleached hair are damaged by a polluted environment. The dry/wet combability, surface contact angle, tryptophan content, and cuticle morphology of the smoke exposed hair were evaluated, and compared to unexposed virgin hair. The results showed that pollution exposure can cause significant chemical damage to hair. In particular, virgin hair exposure to pollution can cause damage to the hair cuticles (higher wet/dry combing), protein degradation, and a more hydrophilic hair surface. The experiment also demonstrated that the styling polymer, polyimide-1 (isobutylene/dimethyl amino propyl maleimide/ethoxylated maleimide/maleic acid copolymer), can provide effective protection against such hair damage.

Gels made with three different polymers widely used as rheology modifiers in cosmetic formulations (cross-linked poly(acrylic acid), cross-linked poly(maleic acid-alt-methyl vinyl ether) copolymer and cross-linked poly(acrylic acid-co-vinyl pyrrolidone) copolymer) were characterized by rheological and sensory evaluation methods to determine the relationship between sensorial perception and corresponding rheological parameters.
