Abstract: Recebido em 16/1/08; aceito em 22/9/08; publicado na web em 15/4/09 DEVELOPMENT OF LIQUID-CRYSTALLINE SYSTEMS USING SILICON GLYCOL COPOLYMER AND POLYETHER FUNCTIONAL SILOXANE. For the construction of the phase diagrams, the method of the aqueous titration was used. There were prepared 5 ternary diagrams, varying the surfactant and the oil phase. The liquid-crystalline phases were identified by polarized light microscopy. The formulations prepared with silicon glycol copolymer, polyether functional siloxane (PF… Show more

“…Silicones are increasingly used in cosmetics because of their many advantages, such as non-comedogenicity, film formation, skin hydration, good skin feel, and consumer acceptance. Thus, the association of liquid crystal and silicones will promote formulations that are more stable, efficient, penetrating, and retain skin moisture (Chorilli et al, 2009).…”

“…They are thermodynamically stable and can be classified as either thermotropic or lyotropic systems. Thermotropics are formed by arrangement of individual molecules (pure substances) and lyotropics, by micelles (surfactants mixed with a solvent, usually water) (Aouada et al, 2006;Chorilli et al, 2009;Prestes et al, 2010; Chorilli et al, 2011;Calixto et al, 2014;Oyafuso et al, 2015). It is well known that surfactants tend to spontaneously self-associate and can form highly ordered aggregates, such as lamellar, hexagonal, and cubic liquid crystalline phases, at higher concentrations (Fraser et al, 2009;Calixto et al, 2014).…”

“…178 LCs are divided into two categories: thermotropics, which are structured by means of temperature, and lyotropics, which occur by association with amphipathic compounds and solvents. The mesophase lyotropics are mostly lamellar, hexagonal, or cubic, 179 as shown in Figure 4. LCs are usually based on water as a solvent, surfactant (may contain cosurfactants), and an oily phase.…”
