“…3), except M. purpureus dye at dyeing pH of 3, woolen yarn treated with mordant FeSO4.7H2O was obtained darker colors than woolen yarn treated with mordant alum. The same result informed that mordant FeSO4.7H2O produced darker colors than mordant alum on polyester cotton and wool fabrics [23,24] and silk and wool fabrics [9]. This is presumably due to the influence of the chemical content available on mordant materials, namely the existence of Fe 2+ from…”

Coastal areas are famous for its diversity and abundance of marine flora and fauna. Several tonns of seaweeds grows annually and during low tide they are easily avaliable either in growing or drift form. The current investigation was focus to target these marine flora to provide an alternative to toxic colorants. The brown seaweed, Stoechospermum marginatum were collected form the coastal area of Arabian sea during low tide. Seaweed colorants can be used as sustainable and eco-friendly source to make a value added product. Extraction process were optimized by varying solvent medium (alkali, acidic and distilled water), solvent concentration and extraction time. Eco-friendly metal salt like ferrous and alumium sulphate were used to developed twenty-four soft shades on S/J 100% cotton. Dye exhaustion, color measurements and fastness properties such as wash, crock and light fastness of resultant fabric have been studied. The optimized condition of extraction process was 5g/L sodium hydroxide for 3hrs processing time. The dyed fabric having 5g/L sodium hydroxide extarcted dye and mordanted with ferrous sulphate shows maximum exhaustion percentage as well as good to very good fastness property while the Δa and Δb values of color measurements shows that the dyed fabric has reddish-yellow shade.

“…Tujuan pewarnaan ini tidak hanya untuk meningkatkan daya tarik produk, tetapi juga untuk membantu pasien membedakan antara obat-obatan yang dikonsumsi dan membantu membedakan dosis dari obat yang sama, sehingga mengurangi kesalahan dalam penggunaan obat (Šuleková et al, 2017). Berbagai zat pewarna, terutama zat pewarna sintesis memiliki dampak negatif bagi tubuh manusia karena bersifat karsinogenik, serta adanya aturan terbaru di negara Jerman, AS, India dan beberapa negara Eropa lainnya yang melarang penggunaan dari beberapa pewarna sintesis, sehingga membuat penggunaan pewarna ini semakin sedikit (Kundal et al, 2016). Hal ini menyebabkan permintaan akan pewarna alami yang berasal dari alam terus meningkat karena sifatnya yang ramah lingkungan, tidak ada efek samping, tidak beracun serta memiliki aktivitas antioksidan yang baik bagi tubuh.…”

The rind of dragon fruit (Hylocereus lemairel (Hook.) Britton & Rose) is a waste material that has not been optimally utilized. The rind contains betacyanin pigment that has many benefits in pharmaceutical products. The study aimed to characterize the physicochemical properties, to evaluate the stability and to apply betacyanin in dragon fruit rind as a natural dye. The extraction process was done by using water as solvent which was sonicated at 50 kHz for 30 minutes at 25 °C. Extract was freeze dried for 48 hours. The dried extract was purified by using preparative TLC and physicochemically analyzed by using UV-Vis and FTIR spectrophotometer. The stability of betacyanin extract against pH and temperature was examined and applied as a dye in tablet imprinting. The result of this study indicated that betacyanin was found at Rf value of 0.6 same as the betacyanin standard. The maximum wavelength of betacyanin was obtained at 534 nm and the IR spectra showed similarity with betacyanin standard with the same functional groups between 4000-600 cm-1 although there was a slight shift in the wavenumber but it still in the range. The stability study were stable at temperature below 40 °C and at range pH 4-6. Betacyanin applications as natural dye of tablet have been successfully carried out with good color stability during 3 months of storage at room temperature.
