Objective: Capsaicin is a bioactive compound with poor solubility in water. Transfersomes can increase the solubility and thus the penetration ofcapsaicin into the epidermis. Transfersomes also offer the advantage of being ultradeformable vesicles that are made using the thin layer hydrationmethod. The aim of this study is to determine the effect of the hydrophilicity of surfactants on the characterization and in vitro penetrative ability ofcapsaicin transfersomes in gels using non-ionic surfactants with different hydrophile-lipophile balances, namely, Span 80, Tween 80, and a mixtureof Span 80, and Tween 80.Methods: The best characterization result for transfersomes is the formula using Tween 80. The total cumulative amount of capsaicin penetratedfrom the transfersome gel using Tween 80 is 1663.89±1.58 mg/cm2, the percentage is 57.96±0.05%, and the flux is 166.38±0.15 μg/cm2.hr−1.Results: In terms of the transfersome gel using a mixture of Span 80 and Tween 80, the cumulative amount of capsaicin penetrated is1539.8±21.23 μg/cm2, the percentage is 54.47±0.75%, and the flux is 153.98±2.12 μg/cm2.hr−1. Finally, from the transfersome gel using Span 80, thecumulative amount of capsaicin penetrated is 1395.10±7.23 mg/cm2, the percentage is 50.80±0.26%, and the flux is 139.51±0.72 mg/cm2.hr−1.Conclusions: The best characteristics resulted from the transfersome formulation using Tween 80, which demonstrated the highest entrapmentefficiency calculation result, the smallest particle size, the best deformability index, and the highest penetration when compared to the other twoformulations.

Hiperurisemia adalah keadaan dimana terjadi peningkatan kadar asam urat dalam darah diatas normal. Tanaman kenikir (Cosmos caudatus) merupakan tanaman yang banyak dijumpai di lingkungan sekitar, serta tanaman yang sudah tidak asing lagi dan telah banyak dikonsumsi sebagai sayuran. Salah satu kandungan dalam kenikir adalah senyawa golongan flavonoid. Pada penelitian ini mikroemulsi ekstrak kenikir digunakan untuk menurunkan kadar asam urat pada tikus yang diinduksi hati ayam. Mikroemulsi dibuat dengan menggunakan virgin coconut oil (VCO) sebagai fase minyak, Tween 80 dan Span 80 sebagai surfaktan dan gliserin sebagai kosurfaktan. Penelitian menggunakan 15 ekor tikus putih jantan galur wistar yang diinduksi jus hati ayam. Tikus dibagi menjadi 3 kelompok, yaitu kelompok kontrol negatif mikroemulsi placebo, kontrol positif mikroemulsi Allopurinol 3,6 mg/200 g BB tikus, serta kelompok perlakuan mikroemulsi daun kenikir  10 mg/200 g BB tikus yang diberikan secara peroral. Pengukuran kadar asam urat dilakukan pada hari ke-0 (kadar awal), hari ke-7 (kadar setelah induksi) dan hari ke-13(kadar setelah perlakuan). Persen penurunan kadar asam urat dalam darah dianalisis secara statistika dengan taraf kepercayaan 95%. Hasil uji statistika menyatakan ada perbedaan antara kelompok kontrol negatif dan positif dengan kelompok perlakuan mikroemulsi daun kenikir memiliki nilai signifikansi 0,000. Sehingga mikroemulsi daun kenikir dapat menurunkan kadar urisemia tikus yang diinduksi ekstrak hati ayam namun memiliki kemampuan yang tidak sebaik mikroemulsi allopurinol. Kata Kunci : Mikroemulsi, Kenikir (Cosmos Caudatus), Hiperurisemia, Ekstrak Hati Ayam, Allopurinol.

The preparation suppositories contain 250 mg of paracetamol on different bases using Novata BD, Novata BCF and composition of Novata BCF/BD (1:1). Suppositories were prepared by the fusion method. The prepared formulations with or without surfactants (Tween 80, Span 60) at concentrations of 2% and 4% (w/w) were tested for hardness, to tal time of de for ma tion, disintegration time, content uniformity and release of the drug. The release of the drug was carried in the apparatus with the stirrer shade in phosphate buffer (pH 7.2) at 100 rpm. The physical properties of the prepared suppositories were according with the requirement of Polish Pharmacopoeia 9th edition. Addition of 4 % Tween 80 to suppository bases significantly increased the drug release from all the investigated formulations. However, incorporation of Span 60 did not result in improvement of the drug release significantly.

Surfactants were evaluated in the greenhouse for their ability to enhance glyphosate [N-(phosphonomethyl) glycine] toxicity to common milkweed (Asclepias syriacaL.) and hemp dogbane (Apocynum cannabinumL.). Ethoxylated amines were among the most effective groups of surfactants. Nonionic ether and ester ethoxylates combined with a dimethyl amine or a quaternary ammonium salt were more effective than any of these surfactants alone. Effectiveness of ethoxylated amine surfactants was altered by pH changes. Cat-ionic surfactants tended to be more effective than nonionic surfactants. With exceptions, surfactants were more effective with increased ethoxylation. Amine surfactant effectiveness increased with increasing concentrations up to 0.3% (w/v). Surfactant effectiveness on a molar basis was more closely related to the ethylene oxide content of the surfactant than was effectiveness on a percentage basis. Contact angle was not related to surfactant effectiveness at high or low surfactant concentrations. Ethoxylated stearyl ether and amine surfactants gave optimum effectiveness at hydrophile-lipophile balance (HLB) values of 15 to 16 and 19 to 20, respectively. Surfactants with a low HLB were usually less effective. Effectiveness of surfactant combinations was quite variable and difficult to predict. Therefore, the indiscriminate addition of surfactants to glyphosate spray mixtures which already contain a surfactant should be avoided.

Abstract Suppositories with cocoa butter containing dehydroepiandrosterone (DHEA) without and with the addition of Span 80 and Tween 80 as surfactants with low and high HLB values were prepared. The physical properties and the drug content of all prepared suppositories were in accordance with the pharmacopoeial requirements. The release study tests in three dissolution media such as water, lactic acid solution at pH 4.2 and phosphate buffer at pH 7.4 were carried out. In acidic and alkalic media only about 10% and 27% of DHEA were released, respectively. The addition of Span 80 to the suppository mass did not improve the release process, but the addition of Tween 80 caused the increase in the amount of DHEA released in the acidic medium to about 35%. The data showed that rectal administration of suppositories with DHEA based on cocoa butter caused about 30% availability and after vaginal administration, only topical activity can be expected. By the addition of Tween 80 to the suppository mass availability of DHEA of about 35% from vaginal suppositories can be achieved.
