: In recent years, SLNs and NLCs are among the popular drug delivery systems studied for delivery of lipophilic drugs. Both systems have demonstrated several beneficial properties as an ideal drug-carrier, optimal drug-loading and good long-term stability. NLCs are getting popular due to their stability advantages and possibility to load various oil components either as an active or as a matrix. This review screens types of oils used till date in combination with solid lipid to form NLCs. These oils are broadly classified in two categories: Natural oils and Essential oils. NLCs offer range advantages in drug delivery due to the formation of imperfect matrix owing to the presence of oil. The type and percentage of oil used determines optimal drug loading and stability. Literature shows that variety of oils is used in NLCs mainly as matrix, which is from natural origin, triglycerides class. On the other hand, essential oils not only serve as a matrix but as an active. In short, oil is the key ingredient in formation of NLCs, hence needs to be selected wisely as per the performance criteria expected.

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.

The results of the research on estimation the molar heat of formation (enthalpy) of model triglycerides found in natural oils and fats are presented. In this work a calculation method and calorimetric one were used. It was found that combustion heat values determined by separate methods are comparable; their difference was a maximum of 155 kJ/kg, and thus was significantly lower than the tolerance for the calorimetric method according to PN 86/C-04062.
