Preparation of Silica Particles Encapsulating Retinol Using O/W/O Multiple Emulsions

Distribution of Macropores in Silica Particles Prepared by Using Multiple Emulsions

“…These results showed that the macropores were packed inside the particles as the concentration of PEG increased. The formation of silica particles with macropores inside the particles in multiple emulsions was confirmed in our previous study (24).…”

Vitamin A enrichment: Caution with encapsulation strategies used for food applications

“…Besides these "classic" systems, other structures have been reported for vitamin A encapsulation. For example, multiple oil/water/oil emulsions and silica particles have been mixed together (Lee, Oh, Moon, & Bae, 2001). The preparation of distearoyl phosphatidycholine liposomes containing entrapped complexes of hydroxypropyl-β-cyclodextrin with retinol has been reported (McCormack & Gregoriadis, 1998).…”

Nanoparticle Coated Submicron Emulsions: Sustained In-vitro Release and Improved Dermal Delivery of All-trans-retinol

“…Liposomes (8), multiple emulsions (9), polymeric systems (10), solid lipid nanoparticles (11,12), egg albumin microspheres (13), and collagen microparticles (14) have been investigated as dermal delivery vehicles of retinoids; however significant challenges remain in the development of highly stable formulations which can deliver sufficient doses of all-trans-retinol to the target skin layers.…”
