Abstract
Produk kosmetik seperti lip balm yang mengandung tabir surya
memiliki keefektifan dapat dilihat dari nilai Sun Protection Factor
(SPF) yang tertera pada label produk kemasan. Banyaknya produk tabir
surya yang beredar dipasaran diperlukan pembuktian untuk melindungi
konsumen dari kosmetik yang tidak memenuhi persyaratan standar
mutu sediaan. Penelitian ini bertujuan untuk mengetahui mutu fisik,
nilai SPF pada beberapa produk sampel lip balm di pasaran, dan
kesesuaian nilai SPF pada label kemasan sampel produk lip balm.
Penelitian ini menggunakan 3 sampel produk lip balm merek X,
Y, Z yang mencantumkan nilai SPF. Sampel dilakukan pengujian mutu
fisik yang meliputi uji organoleptis, homogenitas, pH, daya sebar, daya
lekat, dan titik lebur. Selanjutnya dilakukan pengukuran nilai SPF
secara in vitro diukur absorbansinya menggunakan metode
spektrofotometri UV-Vis dengan panjang gelombang 290 – 320 nm
interval 5 nm dan hasil uji dianalisis berdasarkan persamaan Mansur.
Hasil pengujian mutu fisik pada penelitian ini menunjukkan
bahwa sampel memenuhi kriteria mutu fisik sediaan lip balm yang baik
yaitu seluruh produk homogen, memenuhi rentang persyaratan pH
bibir, memiliki daya sebar dan daya lekat yang baik. Ketiga sampel
produk lip balm merek X, Y, Z yang terukur secara in vitro metode
spektrofotometeri UV-Vis memiliki rata – rata nilai SPF sebesar
17,5989; 12,6685; dan 11,5038. Hal tersebut tidak sesuai dengan label
kemasan sampel produk lip balm.
Cosmetic products such as lip balm that contain sunscreen have
their effectiveness, which can be seen from the Sun Protection Factor
(SPF) value stated on the product packaging label. The large number of
sunscreen products on the market requires proof to protect consumers
from cosmetics that do not meet the requirements for product quality
standards. This research aims to determine the physical quality, SPF
value of several sample lip balm products on the market, and the
suitability of the SPF value on the packaging labels for sample lip balm
products.
This research used 3 samples brand of lip balm products X, Y,
Z which included SPF values. Samples were subjected to physical
quality testing which included organoleptic tests, homogeneity, pH,
spreadability, stickiness and melting point. Next, the SPF value was
measured in vitro and the absorbance was measured using the UV-Vis
spectrophotometric method with a wavelength of 290 – 320 nm at 5 nm
intervals and the test results were analyzed based on the Mansur
equation.
The results of physical quality testing in this study showed that
the samples met the physical quality criteria for good lip balm
preparations, namely that the entire product was homogeneous, met the
lip pH requirement range, had good spreadability and adhesion. The
three samples brand of lip balm products X, Y, Z which were measured
using the in vitro UV-Vis spectrophotometry method had an average
SPF value of 17,5989; 12,6685; and 11,5038. This does not match the
lip balm product sample packaging label.
