Summary: | In order to maintain skin health, experts recommend cleaning the face twice a day. However, the
cleanser can generate negative effects on the skin such as skin tightness, skin dryness, irritation, and
allergies. This research aims to make and evaluate the powder cleanser with active ingredients
of Centella asiatica L. ethanol extracts and providing mildness and moisturizing benefits as well. The
formula consists of ethanol extracts of Centella asiatica L. as active ingredients, sodium cocoyl
isethionate as the surfactant, maltodextrin as absorbent, kaolin as oil adsorbent and exfoliator, and
milk powder as filler. The evaluation of the formula including organoleptic, pH, flowability, moisture
content, washability, foaming ability, foam stability, and surface tension. Optimization of the formula
obtained that the formula consisting of 5% Centella asiatica L. ethanol extracts, 5% maltodextrin, 9%
kaolin, 3% milk powder, sodium cocoyl isethionate 2% was the best formula. It had a pale green color
appearance with specific odor, smooth texture, good flowability, pH of 5,84 - 5,87; the moisture
content of 0,683-0,687%; surface tension of 32,1 –32,3 dyne/cm2 ; forming 54 ml of foam after 5
minutes, and easy to wash. Statistical analysis of stability data at room temperature and the
accelerated test showed that the final formula was stable for 4 weeks. Furthermore, the formula was
non-irritant based on acute skin and ocular irritation test. There was no significant difference in the
degree of skin moisture before and after five days of using the powder cleanser found by the
determination of the transepidermal water loss (TEWL) parameter.
