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 microorganisms (bacteria and fungi) revealed that the above formulation showed a biologic load < 10 CFU/mL in all samples. In conclusion, liquid crystalline systems that have presented formation of a lamellar mesophases were developed. Furthermore, the formulation and products tested presented the adequate microbiological quality in accordance with official recommendations.383-390engCamellia sinensis/glycolic extractLiquid crystal systems/cosmetic applicationsLiquid crystal systems/characterizationLiquid crystal systems/microbiological controlArtigo10.1590/S1984-82502016000300004S1984-82502016000300383WOS:000390332400004Acesso abertoS1984-82502016000300383.pdf
