Acne Treatment

Azelaic (AZ) acid is a non antibiotic drug used for an acne treatment. The AZ dry emulsion power was prepared by mixing power of AZ with dry emulsion base. The 20% AZ cream was obtained by addition of water into powder mixture with a ratio of 1:1 by weight. The dry emulsion base consisted of virgin coconut oil with an emulsifier, hydroxyproplymethylcellulose (HPMC). The physical properties of each primary coconut oil emulsion (COE) were evaluated as percent creaming, theirs viscosity and particle sizes. The results were shown that the emulsion system of 7.5% HPMC provided the suitable formulas with oil droplet particle size 1.23 ± 8.15 micrometer and its viscosity of 30405.02 ± 480.58 cps. After drying process, the moisture content of coconut oil dry emulsion (CODE) was 2.94%. The yield percentage of dry powder was 58%. Moreover, the flowability of dry emulsion powder was appeared to be fair (with an angle of repose of 35.35). After dry emulsion powder mixing with 20 % AZ and water, the AZ cream was appeared to be stable for at least one week with no significantly different in pH and amount of AZ. Thus AZ dry emulsion preparation could be used an alternative recipe for acne treatment with good stability during one week after reconstitution.

Development of stable dry emulsion capable to self- reform into emulsion by reconstitution in water is presented. The major compositions of oil in water (o/w) emulsion were cold pressed-coconut oil (or virgin coconut oil from four different companies) as oil phase and water as phase containing an emulsifier [hydroxypropylmethylcellulose (HPMC)] and a densifier or solid [tapioca starch (T)]. Dry emulsions were prepared by placing liquid emulsion in condition at 60 °C. The percentage yield of dry emulsion was between 59-62%. After sieving, the most flowability data of dry emulsion granules were passable as a result of some oily parts appeared in particles. The moisture contents in dry emulsion granule were relatively low. The antioxidant activity of oil, primary emulsion (PE) and reconstitute emulsion (RE) were also investigated with Trolox as standard. It was found that the order of antioxidant activity of coconut oil as decrease as following: oil, emulsion and reconstitute emulsion respectively. After 2 freeze-thaw cycles, all reconstituted emulsions were shown to be unstable. The four different brands of virgin coconut oil showed no significant different physical and antioxidant properties of PE and RE. Thus, the process of making a virgin coconut oil dry emulsion might not be affected by any different sources of virgin coconut oil.

Yield And Quality

Awareness of virgin coconut oil (VCO) as a functional food supplement has grown enormously. The treatment of raw material and processing parameters is crucial as they affect the overall yield and quality of the oil. Meanwhile, the microencapsulation technology offers better handling, good oxidative stability, and longer shelf life of the VCO powder. Although good quality liquid and powdered oils can be obtained through sophisticated methods, the process involved is expensive and required high maintenance. By utilising dry kernel and coconut milk-based extractions methods, high-grade quality of VCO can be achieved. During microencapsulation, the spray drying method can preserve the phenolic and antioxidant compounds and maintain the low rancidity of the VCO. This paper evaluates the recent findings of the oil extraction methods and the development of VCO microencapsulation. These methods offer good quality, reproducible and economic viability.

Performance And Emission

Biodiesel has become more attractive recently, because of its environmental benefits and the fact that it is made from renewable resources. Over the past few decades, most of the countries depending on diesel engines for transportation. Some of its valuable advantages like highest thermal efficiency made it very popular. At the same time, the cost of diesel fuel is increasing, due to the depletion of fossil fuels. In this current scenario, we need an alternative fuel instead of diesel fuel. Many of the researchers have successfully placed several works on generating energy from different types of alternative sources including solar and some kind of conversion processes including renewable agricultural products into liquid fuel. One of the biggest challenges for developing countries in relation to energy consumption is to develop and implement technologies that help to improve efficiency of automobile engines, also to reduce the emissions of harmful gases and particulate matters. In order to avoid environmental impacts, emissions are reduced or eliminated by introducing renewable energy resources. The present research chronicles the production and testing of renewable biodiesel fuel derived from virgin coconut oil on a diesel engine, to analyses the engine performance and emission characteristics. In the first phase of work, production of biodiesel fuel from virgin coconut oil using transeterification process with two types of catalysts (homogenous and heterogeneous). The preliminary results shows that, with the addition of homogenous catalyst called Potassium Hydroxide (KOH) with methanol shows much higher activity than that of heterogeneous catalysts, and it shows more similar properties with diesel fuel. The results obtained from the chemical test and physicochemical properties of transesterified biodiesel fuel clearly proves the above-mentioned statement. The chemical tests such as GCMS and FT-IR clearly shows that the biodiesel fuel has sufficient amount of volatile components and functional groups. Then, physicochemical properties include, Fire point, Flashpoint, density, and viscosity were analyzed. Finally, Engine performance and Emission characteristics were analysed to confirm, whether this biodiesel fuel is suitable for diesel engines, without any engine modifications. It was found to be, the transesterified virgin coconut oil biodiesel has similar properties to that of the diesel fuel. From the physiochemical properties and engine performance clearly shows that, coconut oil biodiesel is suitable for diesel engine on blending, at a blending percentage level of 20% with conventional diesel fuel. Since the obtained transesterified biofuel can be used as an alternative fuel for diesel engines. The several journal reports and find outs from experimental investigation clearly depicts that the efficiency of the transesterified biofuel mainly depends upon the amount of catalyst adding and type of catalysts present in the biofuel, whether it is homogenous or heterogeneous catalyst is suitable with methanol. Finally, from the analysis made from biodiesel fuel. Coconut Oil Biodiesel fuel has less emission characteristics than that of the diesel fuels.
