Ascorbyl tetraisopalmitate (VC-IP) is a novel form of ascorbic acid characterized by reduced water solubility due to complete acylation with palmitate. This study investigated the potential cosmetic application of VC-IP when encapsulated in lyotropic liquid crystal nanoparticles (VC-IP LCNPs) by using a high-pressure homogenization (HPH) method. The particle size, zeta potential, and polydispersity index (PDI) of the obtained VC-IP LCNPs were determined as 158.

Dynamic high-pressure microfluidization (DHPM) is an emerging treatment technology and has been widely used for the recovery of natural polysaccharides. The aim of the present contribution is to discuss the DHPM-assisted extraction and processing of polysaccharides from some foods and by-products by reviewing the instrument and working principle, procedures, key parameters, and effects of DHPM on the structures, food properties, and bioactivities of resulting polysaccharides. It was found that a DHPM instrument with Z-type chamber is preferable for extracting polysaccharides, and a DHPM with Y-type chamber is applicable for processing polysaccharides.

Introduction And Aims: This study aimed to investigate the efficacy of 3 bleaching methods on stained polymer-based CAD/CAM blocks in terms of surface roughness, hardness stability, discolouration reduction and susceptibility to re-staining following bleaching.
Methods: Two-mm-thick slabs (N = 128) were prepared from CeraSmart (CS), Grandio Blocs (GB), Vita Enamic (VE), and direct resin composite GrandioSO (RC). Coffee-stained specimens (n = 8) were subdivided into bleaching (BL) groups: in-office bleaching (OB), home bleaching (HB), whitening mouthwash (MW), and a control group with 14-day storage in water (CL).
