Scaling of the Scalp with Alcohol Extract of Portulaca oleracea
ABSTRACT
Portulaca oleracea extract in this study suggest the possibility of using scalp hair cosmetics was conducted
for the purpose. 20 subjects composed of bachelors and bachelorettes in their 20s, who consented to this
study after being given a full explanation, underwent patch tests with 0 to 2% alcohol extract of purslane. The
results were evaluated macroscopically and by use of a mexameter. Cutaneous erythema was not observed
in cases of 0 to 1% extract, and thus it was proved to be safe for cosmetics. Out of 27 women in their 20s
who consented to this study after being given a full explanation, 14 were given a scaling agent containing 1%
alcohol extract of purslane experimental Group. In the case of the other 13, the extract was not contained in
the scaling agent control Group. Two types of scaling agents were applied to respective groups, and were let
stand for 15 minutes. Then, all of subjects shampooed their hair and let the cold breeze blow their hair dry.
Their scalps were scanned at most 9 times (0, 3, 6 and 9 times). The results showed that dead skin cells and
oxidized sebum came away earlier than normal, and that the scalp did not become dry after the application of
the agent, and moreover that reddish regions subsided. It implies that the scaling agent containing the alcohol
extract of purslane is superior to the one containing only ethanol and glycerin in anti-inflammatory, antibacterial
and sedative effects, and the results are consistent with previous researches regarding the alcohol extract of
purslane.
