All parts of A. indica (neem) and R. communis (castor) plants have mostly been used as natural remedies in the control and treatment of several ailments, control of pests and insects, animal feeds and production of industrial products globally. The seed oils of A. indica and R. communis are known to have antidiabetic, anti-helminthic, antifertility, antioxidant, antibacterial, anti-inflammatory, anti-cancer, insecticidal and mosquitocidal activity. This study reports for the first time the chemical composition of A. indica and R. communis seed oils from Marigat, Baringo County, Kenya. Seed oils of A. indica and R. communis were   extracted from mature dried seeds through cold pressing and boiling respectively and chemical composition determined using Gas Chromatography (GC)-Mass Spectrometry (MS).  The constituents of both seed oils were dominated by saturated and unsaturated fatty acids, cyclic esters and methyl esters. The predominant constituents of R. communis were (Z)-6-Octadecenoic acid (37.33%), Ricinoleic acid (30.22%) and 13-Hexyloxacyclotridec-10-en-2-one (26.67%) while those of A. indica were 2-hexyl-1-decanol (30.97%), Octadecanoic acid (29.69%) and Oxalic acid, 6-ethyloct-3-yl ethyl ester (15.55%). Oils contained Hexadecanoic acid and Octadecanoic acid which are used in the manufacture of several products such as candles, soaps, lotions, perfumes and cosmetics. Octadecenoic acid is important in control of human diseases and Ricinoleic acid in production of alkyd resins for surface coating and biofuel.  From the results, A. indica and R. communis seed oils constituents have potential in the agricultural, industrial, comestics and pharmaceutical sectors but require further fractionation to isolate the bioactive compounds.

Modified alkyd resins with different amounts of vegetable oil contents (sunflower oil) and different catalysts are synthesized with the incorporation of post-consumer polyethylene terephthalate (PET) as a partial substitute for phthalic anhydride. It is found that the properties of the products obtained are directly related to the oil content. The polymerization reactions are followed by the acid value. The modified binder contains 50% oil and 10% PET in the presence of LiOH as the catalyst by using microwave irradiation. The AV value is attained in a short amount of time; it is found that the glass Transition Temperature (Tg) of the modified binder is -1.7 °C. The stiffness and roughness of the printed fabrics by using the modified binder are better than those of the commercial binder for both cotton and cotton/polyester fabrics. Moreover, it is clear that the overall fastness properties of the fabrics printed by using the modified binder in the formulation of printing pastes are higher or comparable to those that use commercial binders.

Purpose This study aims to propose a solution to decrease the environmental pollution caused by alkyd resins that harm the environment during their production and use. Design/methodology/approach A commercially produced polish formulation was used in the study. To reduce the use of this formulation in finishing polish, a water-saturated transparent solution of hydroxyethyl cellulose was used as a transparent filling material. Findings The use of hydroxyethyl cellulose at its optimum concentration in finishing polish only reduced the gloss by 0.027 per cent. The amount of alkyd was reduced by 24 per cent in weight. Research limitations/implications The literature contained highly limited information on this subject. No transparent filling material was found. Thus, no comparison can be made with other studies. Practical implications The results obtained from this study can help manufacturers in the polish industry to produce varnish in a more cost-effective and eco-friendly way. Originality/value Considerable amount of volatile organic compounds released into the atmosphere as a result of the use of solvent-based dye/varnishes in the woodworking industry alone proves the importance of water-based systems. The results of this study indicate both economic and environmental gain.
