The Impact

This study aimed to investigate the impact of VCO and castor oil compositions on the physicochemical properties of liquid soap from patikan kebo (Euphorbia hirta) extract and compare it with the marketed liquid hand-soap. The liquid hand-soap was manufactured by adding patikan kebo extract with VCO and castor oil as fatty acid sources. The concentration of VCO and castor oil were varied in 5 formula with ratio 1 : 0, 3 : 1, 1 : 1, 1 : 3, and 0 : 1 of 200 mL of soap perspectively. Several tests such as organoleptic inspection, homogeneity, density, viscosity, foam volume and stability, pH, insoluble materials, free fatty acids, total active ingredients, and total plate number, were performed to determine the physicochemical properties of prepared handsoap. The results of the five formulas were known to the greater VCO the higher the viscosity and percent height of foam, the greater the castor oil the higher the value of specific gravity The five liquid soap formulas produced meet the requirements of SNI 2588-2017. The second liquid soap formula with a ratio of VCO and castor oil 3: 1 was declared to be the best product with free fatty acid 0.78%, pH 8.31, total active ingredient 24.3%, ethanol insoluble material 0.29%, specific gravity 1.09 g/mL, foam high stability 82.85%, and no colonies in testing the Total Plate Figures. It can be concluded that variations in the concentration of VCO and castor oil may affect the physicochemical properties of liquid soap for hand washing extracted from Patikan kebo.

Abstract Studies were made of the influence of a number of polymerization variables on the tensile strength of vulcanized evaporated films from low-temperature high-solids GR-S latexes. Previous reports of film tensiles on the order of 3000 pounds per square inch for latexes of 70/30 butadiene-styrene charge ratio were confirmed. The levels of accelerator necessary for optimum vulcanized properties were found to be considerably lower than those normally used, particularly for latexes shortstopped with dithiocarbamate salts. Microscopic coagulum found in some latex samples had a pronounced effect in decreasing film tensile of vulcanizates. Cured films from latexes emulsified with mixtures of fatty acid and rosin soap possessed considerably better tensile strengths than those from latexes using all fatty acid soap emulsification. Wide variations on Mooney viscosity had relatively little effect on ultimate film tensiles. Incorporation of small amounts of lignin into the latex as the ammonium or sodium salt decreased cure rates of films and aided in giving more reproducible tensile results. Both lignin and the sodium salt of cresyl monosulfide improved the aging characteristics of films.

The structural damage of molecules irradiated by electrons is generally considered to occur in two steps. The direct result of inelastic scattering events is the disruption of covalent bonds. Following changes in bond structure, movement of the constituent atoms produces permanent distortions of the molecules. Since at least the second step should show a strong temperature dependence, it was to be expected that cooling a specimen should extend its lifetime in the electron beam. This result has been found in a large number of experiments, but the degree to which cooling the specimen enhances its resistance to radiation damage has been found to vary widely with specimen types.

Effect Of Light

Cyanobacteria are Gram negative prokaryotes that are capable of oxygenic photosynthesis. Although there are many similarities between eukaryotes and cyanobacteria in electron transfer and phosphorylation during photosynthesis, there are two features of the photosynthetic apparatus in cyanobacteria which distinguishes them from plants. Cyanobacteria contain phycobiliproteins organized in phycobilisomes on the surface of photosynthetic membrane. Another difference is in the organization of the photosynthetic membranes. Instead of stacked thylakolds within a chloroplast envelope membrane, as seen In eukaryotes, IntracytopIasmlc membranes generally are arranged in three to six concentric layers. Environmental factors such as temperature, nutrition and light fluency can significantly affect the physiology and morphology of cells. The effect of light Intensity shifts on the ultrastructure of Internal membrane in Anabaena variabilis grown under controlled environmental conditions was examined. Since a major constituent of cyanobacterial thylakolds are lipids, the fatty acid content also was measured and correlated with uItrastructural changes. The regulation of fatty acid synthesis in cyanobacteria ultimately can be studied if the fatty acid content can be manipulated.
