Evaluation of sunscreening and antibacterial activity of the cream containing pomegranate peel extract

Abstract

Cosmetic products are formulated for application on the body for the purpose of
cleansing, beautifying, or altering appearance and enhancing the beauty. The ozone layer in the
stratosphere practically prevents the UV photons from reaching the earth’s surface of concern
for human skin damage, therefore, only UV-B and UV-A radiation are relevant. In the present
study an attempt has been made to formulate a cream containing alcoholic extract of
pomegranate peel extract. The quantity control parameters of Punica granatum were performed
as per WHO guidelines. The cream was formulated using pomegranate peel extract in two
concentrations (10% and 25%). The UV analysis of different concentrations of prepared creams
are done along with standard cream which has TiO2 as the active ingredient. The extraction of
peel was carried out by continuous hot percolation using Soxhlet apparatus and the
phytochemical screening revealed the presence of flavanoids, tannins, anthocyanins and
polyphenolic compounds. The evaluation of antibacterial activity is done by cup and plate
technique using ethanolic extract of pomegranate peel against Staphylococcus aureus,
Pseudomonas aeruginosa. The results showed that the ethanolic extract of pomegranate peel
has very good sensitivity against both gram positive and gram negative organism.
