Development of nanotechnology-based drug delivery systems with olive vegetable oil for cutaneous application BJPS
Silva,Silas Arandas Monteiro e; Lacerda,Rísia; Bernegossi,Jéssica; Chorilli,Marlus; Leonardi,Gislaine Ricci.
ABSTRACT Liquid-Crystalline Systems represent active compounds delivery systems that may be able to overcome the physical barrier of the skin, especially represented by the stratum corneum. To obtain these systems, aqueous and oily components are used with surfactants. Of the different association structures in such systems, the liquid-crystalline offer numerous advantages to a topical product. This manuscript presents the development of liquid-crystalline systems consisting, in which the oil component is olive oil, its rheological characterizations, and the location of liquid crystals in its phase map. Cytotoxic effects were evaluated using J-774 mouse macrophages as the cellular model. A phase diagram to mix three components with different proportions...

Green tea glycolic extract-loaded liquid crystal systems: development, characterization and microbiological control BJPS
Bernegossi,Jéssica; Barbosa,Raquel Maria Cunha; Rustice,Patrícia Maciel; Chorilli,Marlus.
ABSTRACT Liquid crystal systems (LCSs) have interesting cosmetic applications because of their ability to increase the therapeutic efficiency and solubility of active ingredients. The aim of the present research was to develop green tea glycolic extract-loaded LCSs, to characterize and to perform microbiological control. The ternary phase diagram was constructed using polysorbate 20, silicone glycol copolymer (SGC) - DC 193(r), and distilled water with 1.5% glycolic green tea extract. The systems were characterized by polarized light microscopy. Formulations selected were characterized as transparent viscous systems and transparent liquid system indicated mesophases lamellar structure. The results of the microbiological analysis of mesophilic aerobic...
