Abstract(s)
The Hop (Humulus lupulus L.) are known worldwide as an essential flavor in the beer
industry. Its compounds have been showing health benefits in terms ofphytochemical,
pharmacological and biological profiles, due to their antimicrobial, antioxidant, anti-inflammatory
and anticancer activities. This study intends todevelop a gel formulation incorporating
hydroalcoholic extracts of different varieties of hops such as Cascade, Polaris and Spontaneous,
from the cones and thevegetative plant parts, in different percentages. The essential oil of Thymus
zygis was used as a natural conservative and the analysis of the composition was made byGC and
GC-MS. Later evaluation of the physical-chemical parameters, stability and capacity to inhibit
microbial growth was made. The pH measurement results of theformulations tend to be adjusted to
the natural pH skin. The relative density obtained values of 1 and 0.857. It was found that there were
no changes in the phase separation in the centrifugation, vibration, stability and accelerated test.
However, changes were observed in the UV-Visible spectra, in texture, consistency and viscosity,
and in the color test. In the light test there was phase separation in the samples, which may be related
to the manufacturing technique of the formulations.However, this formulations anti aging with
phenols from Hop can be development in order to obtain formulations with relevant properties for
the consumers and the cosmetic industry.
