The droplet sizes of emulsions obtained from all SEFs containing structured SB derivatives were significantly (p < 0.05) smaller than those of emulsions obtained with the two unmodified SB grades. The flow rate was set at 1 mL min−1, the column temperature was 40 °C and a wavelength of 250 nm was used for detection. Higher droplet size therefore correlated with increased oil concentration as was also evident in SBO formulations. 16 Learn How to Get Rid of and Even Prevent Mask AcneThese 3 simple steps teach you how to get rid of mask acne and prevent it from coming back! Natural lipids such as SB and PKO are GRAS compounds and with regard to safety issues would thus represent the excipients of choice for lipid‐based formulations. First, the samples were analyzed by peak identification of the different FAMEs to a standard FAME‐Mix (Sigma CRM47885, Steinheim, Germany). Practical Application: The structured triglycerides synthesized in this work on the basis of natural shea butter oils could function as suppository bases and oil phase in oral and parenteral lipid‐based formulations for improving the solubility and absorption of poorly soluble drugs. Share Share on Facebook Tweet Tweet on Twitter Pin it Pin on Pinterest. It is well described that during random interesterification, saturated fatty acids of most vegetable oils, usually located at the outer sn‐1 and sn‐3 positions of the triglyceride may get transferred to the sn‐2 position.31 During lipid digestion in the upper GI tract stearic acid located at the sn‐2 position (2‐MAG) of triglycerides will be absorbed into the systemic circulation without digestion by the intestinal lipase since the enzyme typically digests at sn‐1 and sn‐3 positions.32, 33 Free stearic acid, in contrast, may complex with calcium and magnesium ions to form poorly absorbed soaps in the intestine.31 In our present investigation, modified SB may contain sn‐2‐bonded stearic acid and/or free stearic acid (FFA). All reactions were started by adding 10% (wenz/woil) Lipozyme TL IM to the corresponding oil (average calculated molecular weight of 716.63 or 885.17 g mol−1 for PKO and SB, respectively).21, 22 PKO and SB reaction mixtures were incubated with magnetic stirring during 90–112 h at 50 and 60 °C, respectively. Thin‐layer chromatography (TLC) was used to preliminarily check the modification of the oils during the transesterification reaction with glycerol. The organic solvent was then evaporated under a stream of nitrogen. Both processes led to different mixture compositions, which were subsequently studied to determine their capability to solubilize Celecoxib. For GC‐analysis (GCMS‐QP2010S, Shimadzu, Duisburg, Germany) of fatty acid methyl esters a BPX‐70 column (0.25 mm diameter, 0.25 μm film thickness, 30 m length; SGE Analytical Science, Victoria, Australia) was used. From literature it is well known that TAGs can be subjected to enzyme‐catalyzed acidolysis as shown for instance for cocoa‐butter equivalent production or for the synthesis of structured triglycerides such as Betapol (1,3‐oleoyl‐2‐palmitoyl‐glycerol) for which several concepts using a variety of commercial lipases have been described.19, 20 In the present study, we have investigated the lipase‐catalyzed modification of SB and PKO with the aim to improve their applicability in oral lipid‐based drug delivery systems for pharmaceutical use. Moreover, emulsions obtained from SEFs containing structured SB derivatives were characterized by a lower polydispersity, which is an indicator for droplet homogenity.24 All emulsions (i.e., 100‐fold aqueous dilutions of the different SEFs) were stored at 20 ± 2 °C for 24 h. Thereafter, they were examined for phase separation and droplet size variation. Values of determinations were recorded as mean ± standard deviations (SDs). Table 3 shows properties of the self‐emulsifying oil formulations (SEFs), in the anhydrous form (before dispersion in water) and in the hydrated state (after dispersion in aqueous phase). Natural lipids which are generally regarded as safe (GRAS) would thus represent the more favorable excipients, but the natural lipids commonly used in LCFS type III formulations have a relatively low drug solubilizing capacity and thus require the use of surfactants and/or cosolvents. Values of determinations were recorded as mean ± standard deviations (SDs). 635405. There are many carrier oils to choose from. This triple-combination will cleanse your body, while adding moisture to enhance your natural glow. Palm kernel oil is cold pressed from the kernels of the oil palm's fruit. IOG, KZ, and UTB thank the COSMOS project, which has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No. Injector and detector temperatures were set at 250 °C. Incorporation of one or two equivalents of hexanoic acid enabled better Celecoxib solubilization than the diglyceride‐rich oil. For the formation of DAGs and MAGs, glycerol was added to the corresponding oil in a molar ratio of 1.5:2 (Figure 1). The reactions were stopped by extracting them twice with one reaction volume of n‐hexane. We also thank Novozymes for the generous gift of lipase TL IM. Therefore, tailoring these natural triglycerides (TAGs) into structured derivatives with potential for improved solubilization capacity and excipient miscibility would be desirable. Therefore, products from PKO modification and the MAG/DAG‐rich product of SB glycerolysis might perform much better in combination with other APIs. Palm kernel oil is cold pressed from the kernels of the oil palm's fruit. During the transesterification reactions the NEFA percentage reached 15% for SB and 25% for PKO, while during the acidolysis these values were 36 and 27%, respectively. It has a rich, caramel, nutty aroma and light brown color. Kernel Fresh Premium.

The droplet sizes of the diluted emulsions are shown in Table 3 while Figure 4 depicts the appearance of the anhydrous emulsions obtained by mixing the SEFs with distilled water. A total of 0.1 mL of the supernatant then was diluted to 10 mL using acetonitrile. After an equilibration time of 30 min, the droplet size and polydispersity index of the resulting emulsions were determined using a Zetasizer (Malvern Instruments, Germany) at 25 °C and a light scattering angle of 90°. Priest Cedex, France). A total of 0.1 mL of the resulting stock solution was then further diluted to 1 mL using acetonitrile. The composition of the resulting mixtures is given in Table 2. The EFA or NEFA amount of the samples was calculated by comparing the EFA amount determined by the NaOMe method toward the whole FA amount determined by the H, Solubility of Celecoxib in unmodified and enzymatically modified shea butter (SB) and palm kernel oil (PKO) (mean of. While they are great for the skin, they tend to go rancid quickly and should be avoided in large amounts. Sale. SB is predominantly composed of stearic acid and oleic acid, the major component of PKO is lauric acid.13, 14 The longer chain length of stearic acid and oleic acid may be more amenable to extensive esterification and hydrolysis than lauric acid. It is very similar to coconut oil in that it has a high percentage of lauric acid, which adds a smooth texture to body butters, soaps, and salves. Argan Oil is expensive, as is Rosehip Seed Oil, but in small amounts, they can do wonders for your skin. Preliminary experiments (data not shown here) had indicated that stable emulsions typically would either form spontaneously or not at all.
