| dc.description.abstract | Background : The content of orange peel is phenolic compounds are known to
have activity as antioxidants which can be made to face mist skincare that meet the
standard for face mist for moisturizers.
Purpose : to test the antioxidant activity of sweet orange peel, formulate the extract
into a face mist, measure the antioxidant activity of the face mist, and examine the
moisturizing effectiveness of the face mist.
Method : Experimental methods were used in this research. The extract was
obtained by maceration using 96% ethanol solvent and concentrated. The
antioxidant activity was conducted using the DPPH with a maximum wavelength
of 516 nm. Evaluation of face mist includes organoleptics, pH, viscosity, and
spraying patterns. Long-term stability tests were carried out at room temperature
(28±2)℃ for 12 weeks and accelerated stability tests were carried out for 6 cycles
at temperatures of (4±2)°C and (40±2)°C.. The irritation test was used by 10
volunteers who were dripped with the face mist and observe if irritation occurred.
The effectiveness test as moisturizer was done by spraying the preparation on the
back of the volunteer's hand and the moisture was measured after 5, 30, 60, 120,
180 minutes and mesured again after 5 days application of face mist use using a
skin analyzer.using a skin analyzer.
Result : The extract yield obtained 32.85%. The IC50 value of the ethanol extract
of sweet orange peel was 9.7651 μg/mL, the vitamin C comparison was 3.1685
μg/mL, and the face mist F1(0.048%) is 128.4169 μg/mL, F2 (0.073%) is 114.3516
μg/mL, and F3(0.097%) is 91.1397 μg/mL. The product face mist is a slightly thick,
transparent yellow liquid with a characteristic orange peel odor, homogeneous,
stable during storage, the spray pattern diameter is (7.17 ± 0.35) cm to (17.90 ±
0.89) cm. Stability test pH 5.67- 5.40 and viscosity 15.467cP-15.833 cP. Irritation
test result is non-irritating product. The moisturizing effect to the skin after 3 hours
of use represent the recovery percentage of the face mist formulation for F0, F1,
F2, F3, and positive control is 75%, 144%, 177%, 242%, and 281%. The
moisturizing effect to the skin after 5 days of use represent the percentage of the
face mist formulation for F0, F1, F2, F3, and positive control is 205%, 261%, 313%,
315%, and 294%.
Conclusion : The ethanol extract of sweet orange peels has very strong antioxidant
activity. The ethanol extract of sweet orange peels is formulated into a concentrated
face mist which has strong antioxidant activity, provides a good moisturizing effect,
qualify as facial care product with pH 4.5-6.5, viscocity <150 cP, minimum
spreadibility 5 cm – 7 cm, and is stable during storage. | en_US |
