Penggunaan hijab dahulu hanya dianggap sebagai item yang 'ketinggalan zaman', namun berbeda dengan saat ini. Hijab kini telah dijadikan sebagai salah satu item fashion wajib yang dikenakan oleh sebagian besar wanita muslim di Indonesia. Meskipun populasinya semakin meningkat, namun peningkatan ini tidak diimbangi dengan perawatan khusus rambut yang tertutup di balik hijab, karena sering mengalami masalah rambut akibat nutrisi shampo yang kurang mendukung bagi wanita berhijab, sehingga diperlukan suatu perawatan khusus selain shampoo untuk mengatasi masalah ini. Produksi buah mentimun yang cukup tinggi di Indonesia masih belum sebanding dengan pemanfaatan buah mentimun itu sendiri, mentimun umumnya hanya dikonsumsi di kalangan masyarakat, padahal ekstrak buah mentimun kaya akan metabolit sekunder seperti sulphur dan silikon yang dapat digunakan untuk menstimulasi pertumbuhan rambut dan menutrisi rambut rontok pada wanita  berhijab. Penelitian diawali dengan pembuatan hair tonic dengan menggunakan bahan yaitu ekstrak mentimun (C. sativus) 25%, dan bahan tambahan seperti etanol 96 %, menthol, propilenglikol, metil paraben, natrium metabisulfit, akuades, dengan berbagai konsentrasi. Setelah pembuatan hair tonic maka dilakukan beberapa evaluasi fisik pada sediaan untuk melihat kestabilannya pada masing-masing konsentrasi untuk memenuhi persyaratan sediaan hair tonic dan mengatasi masalah pada rambut berhijab.Kata Kunci: Ketombe, hair tonic, mentimun, hijab, kosmetik

Kersen (Muntingia calabura L.) contains flavonoids that have the potential as antioxidants. However, its hydrophilic characteristics cause poor penetration so that its bioavailability is low. Research had been carried out on the preparation of ethanol extract of cherry leaves in ethosomal vesicle carriers. This study aimed to obtain the optimal phytosome suspension formula. Methods: Sample extraction was carried out by maceration method using ethanol as a solvent and was delipidated was by liquid-liquid method with n-hexane. The characterization of the extract included organoleptic, water-soluble extract content, ethanol soluble extract content, water content, ash content, acid insoluble ash content, and residual solvent.  flavonoid contents were carried out by the TLC method and antioxidant activity was determined using DPPH method. Phytosome preparation was prepared by solvent evaporation and thin film hidration with ratio of extract and phosphatidylcholine 1:1 with concentration of 0.5% (A); 1% (B); and 1.5% (C). The characterization included observing morphology of vesicles using optical microscope, determining the size distribution of vesicles using PSA, and calculating the sorption efficiency using a spectrophotometer at max 281 nm. Results: The characteristics of extract were dark green; thick; distinctive aroma; ethanol soluble content were 70.91%; water soluble content were 32.5%; water content were 1.19%; ash content were 1.25%; acid insoluble ash content were 0.49%; and the remaining solvent was 0. The identification of flavonoids showed positive results. The extract has flavonoids and strong antioxidant activity with 62.71 g/mL for IC50. The shape is single layer large vesicle (LUV), diameter was 445.7 nm (A); 420.7 nm (B); and 419.6 nm (C). Vesicle entrapment efficiency was 5.83% (A); 47.575% (B); and 68.81% (C). It can be concluded that the optimal phytosome suspension formula is C with 1.5% phosphatidylcholine and 1.5% of extract.

Background:  Majapahit leaves (Crescentia cujete L.) are known to contain biochemical compounds namely tannins, terpenoids, alkaloids, and saponins which are effective as antimicrobials. Objective(s): This study aimed to formulate ointment from n-hexane extract of majapahit leaves and to known its antimicrobial activity against P. aeruginosa. Methods: ointment ingredients are vaselin, cera alba, liquid paraffin, and menthol and 2% of Majapahit leaves n-hexane extract. Ointment stability test included organoleptic, homogeneity, viscosity, pH, and irritation tests. Evaluation of stability of ointment was obtained by using cycling test method. The irritation test was carried out by open patch test on 6 panellists. Diffusion method is used to obtain antimicrobial activity. Results: The antimicrobial   activity    (diameter   inhibition   zone)   of    the    ointment    against Pseudomonas aeruginosa bacteria was 11 mm and the positive control was 13 mm. The formula showed no change on texture, colour, aroma, viscosity, homogeneity, but there was slight increase in viscosity and pH. The ointment showed non-irritating for panellists thus the ointment formulation is safe for topical use. Conclusion: 2% n-hexane extract of Majapahit leaves can be formulated into ointment with good stability with strong antibacterial activity and non-irritating. Keywords:  antibacterial  activity,  majapahit  leaves,  N-hexane  extract,  ointment,  Pseudomonas aeruginosa
