AbstractThe authentication of neem oil and its blending with inexpensive vegetable oil, such as, palm oil is a common practice in the neem oil industry. This study was conducted to investigate the neem kernel (Azadirachta indica) oil (NKO) by blending with palm oil and characterize it by studying its effect on the physicochemical properties, dielectric properties and fatty acid profiles of the blend. Blending significantly influenced the color, dielectric, structural and antimicrobial properties of the virgin oil. The NKO was rich in oleic (44.97%), stearic (21.27%), palmitic (16.88%) and linoleic acids (14.08%). The addition of palm oil into NKO significantly influenced the fatty acids profile , which was further confirmed by the FTIR spectra and the dielectric data. Overall, determination of moisture content, palmitic and stearic acid content, color parameter "a" and dielectric measurements were found to be fastest and precise way to detect the NKO and PO blends.

The enormous use of metallic wood preservatives has caused destructive impact on environment as well as human health. Therefore realizing the urgency of switching to Environment friendly options such as natural oils are being tested for their antimicrobial properties. The present study aimed at investigating potential of Neem oil against the growth ofdecaying fungi. The ability of Neem oil to inhibit mycelia growth of Schizophyllum commune, Fusarium oxysporum, Fusarium proliferatum, Coniophora puteana and Alternaria alternata was tested at different concentrations of 0.25, 0.50, 0.75, 1.0, 2.0, 4.0, 6.0, 8.0 and 10%. Results of the study revealed Neem oil concentrations above 2% were significantly inhibitory to all the tested fungi.

Study Results

Permethrin Cream 5%, a topical scabicidal agent, is usually used for the treatment of infestation with Sarcoptes scabiei (scabies). Nowadays, neem oil,  a vegetable oil pressed from the fruits and seeds of the neem (Azadirachta indica A.Juss), is reported having an antiscabies effect. The aim of the study was to formulate and evaluate the physical properties of cream containing neem oil 5%. Methods of the study were characterization of physicochemical properties of neem oil, preparation and physical stability study at room temperature (25 oC) and 40 oC for three months storage of the neem oil 5% cream. Physical evaluation involved organoleptic, homogeneity, pH, tipe of cream and  viscosity. The study results showed that all of the physicochemical properties of neem oil met the requirement. The cream were white to yellowish white, characteristic neem oil odor, homogenous cream, pH ± 8, viscosity approximately 2000-8000 cps and o/w cream. Three months storage of the cream showed that the formula resulted a stable cream physically.Keywords: neem oil, permethrin, scabies, Azadirachta indica A.Juss

Chitosan is an environmentally friendly agent that is used to achieve the antimicrobial properties of textiles. Nowadays, the binding of chitosan to the textiles has been thoroughly researched due to the increasing demands on the stability of achieved properties during the textile care processes. Most crosslinking agents for chitosan are not safe for humans or environment, such as glutaric aldehyde (GA) and formaldehyde derivatives. Eco-friendly polycarboxyilic acids (PCAs) are usually used in after-treatment. In this work, chitosan powder was dissolved in citric acid with sodium hydrophosphite (SHP) as a catalyst. Standard cotton (CO) and polyester/cotton (PES/CO) fabrics were pretreated in 20% NaOH, similar to mercerization, in order to open the structure of the cotton fibers and hydrolyze polyester fibers, continued by finishing in the gelatin chitosan bath. Afterwards, the hot rinsing process, followed by drying and curing, closed the achieved structure. The main objective was to achieve durable antimicrobial properties to multiple maintenance cycles CO and PES/CO fabric in order to apply it in a hospital environment. The characterization of fabrics was performed after treatment, first and fifth washing cycles according ISO 6330:2012 by field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR-ATR), electrokinetic analysis (EKA), by the determination of tensile properties and mechanical damage (wear), and the antimicrobial activity. The application of 20% NaOH led to the swelling and mercerization of cotton cellulose, and hydrolysis of polyester, resulting in better mechanical properties. It has been confirmed that the chitosan particles were well implemented into the cotton fiber and onto to the polyester component of PES/CO blend. The presence of chitosan was confirmed after five washing cycles, but in lower quantity. However, achieved antimicrobial activity is persistent.

Polyhydroxyalkanoate (PHA) is biodegradable polyester, which can be synthesized by many microorganisms through catabolic pathway, without producing any toxic byproduct. Owing to it special and versatile properties, this polymer has attracted much attention as a possible replacement for traditional plastics in the future. Feasibility of PHA production from inexpensive substrates was investigated by using Alcaligenes latus, gram negative bacteria, which can be grown in various types of wastewater. Four substrates were employed, i.e., wastewater from palm oil industry (oil-lean palm oil and oil-rich palm oil), wastewater from soymilk industry, and a control synthetic wastewater. The results show that PHA copolymer, poly(hydroxybutyrate-co-hydroxyvalerate) P(HB-co-HV), is produced from the metabolic pathways of A. latus. Soxhlet extractor was then employed in extraction process of the PHA copolymer. The resulting copolymer was characterized by Fourier Transform Infrared (FTIR) spectroscopy, and Nuclear Magnetic Resonance (NMR) Spectroscopy.
