Abstract
The purpose of the current work is to investigate the incorporation of olive leaves extract
standardized for oleuropein which have antioxidant, anti inflammatory, skin protectant and antiaging
properties into stable topical moisturizing day cream formulations. The physiochemical and
rheological properties, and accelerated stability tests of three cream formulas containing different
concentrations (0.1%, 0.4% and 1.0% w/w) of olive leaf extracts were assessed and compared
with commercial cream product containing no olive leaf extract. A questionnaire was distributed
to 100 volunteers to use the prepared creams containing olive leaf extracts and to compare with
the commercial cream containing no olive leaves extract. All physical and rheological properties
of the prepared formulations were found to be the same as the commercial cream product.
Stability studies showed a stable homogenous appearance and effective cream during three
months of storage at room temperature. Most of the volunteers are satisfied with the creams
containing olive leaves extract, and have noticed significant differences between these creams and
the cream containing no olive leaves extract.
