Solubility results obtained in all other modified lipids were less favorable, i.e., Celecoxib solubility was lower than in the corresponding natural lipid. Subsequent chemical refinement of the fatty phase with n‐hexane gives rise to the butter, while fractionation of the acetone extract yields oleine and stearine.9 However, although SB has been fully characterized with respect to its fatty acid composition as well as other physicochemical properties,13, 14 is used in food industry and in the manufacture of cosmetic products and pharmaceutical formulations for cutaneous application, to date the usefulness of SB for oral drug delivery systems remained unexplored. During digestion, TAGs initially undergo partial hydrolysis into free fatty acids (FFA) and diglycerides (DAG) by gastric lipase. The final product (anhydrous emulsion) was then stored at 20–25 °C for further use. Droplet sizes of emulsions obtained from SEFs made from natural lipids and their structured derivatives were dependent on both, the lipid composition and the oil‐surfactant ratio used for the preparations of the SEFs. Once everything is completely blended, add the essential oil. Enhancement of Lipase CAL‐A Selectivity by Protein Engineering for the Hydrolysis of Erucic Acid from Crambe Oil. Lipase‐catalyzed transesterification of SB with hexanoic acid, however, resulted in a lipid in which Celecoxib solubility was significantly increased. Values of determinations were recorded as mean ± standard deviations (SDs). The solubilizing capacity of a lipid is, however, a result of both, lipid constituents and physicochemical properties of the API. They were then equilibrated to 37 °C, before 1 mL of each of the anhydrous mixtures was added to a beaker containing 99 mL demineralized water and the resulting mixtures were manually shaken with ≈60 rpm for 1 min for emulsification. Kernel Fresh Premium Moisturizing Oil. Colloids and Surfaces A: Physicochemical and Engineering Aspects. In emulsions obtained from SEFs with a 1:2 oil‐surfactant mix ratio no significant difference (p < 0.05) in droplet size when comparing SEFs made from PKO or its structured derivatives was observed. Formation of DAG‐rich lipids was performed in a similar manner. Increasing the solubilizing capacity of these natural lipids without changing their regulatory status would be a unique chance for making use of these massive sources of natural lipids. Share your experience below. It is also useful for softening and healing dry or itchy skin or lips, as well as moisturizing hair. 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. They all have different characteristics and benefits. Working off-campus? Either one will add some air to the mixture, but if you keep it on the double boiler, it will flatten out as you stir it. Analysis of 1 μL sample was carried out with a flow rate of 0.57 mL min−1. The upper organic layer was collected. Then, the collected organic phase was dried with anhydrous sodium sulfate. Besides determining the solubility of Celecoxib in the different lipids, miscibility of the respective oils with model surfactants and cosurfactants was investigated to ascertain the suitability of the oils as potential LFCS type III (i.e., SMEDDS) excipients. Although structured SB and PKO (15.8 ± 0.4 mg mL−1) do not differ significantly (p < 0.05) as per the amount of Celecoxib dissolved, the use of the modified oils enhanced Celecoxib solubility in SB (15.5 ± 1.3 mg mL−1) in comparison to shea butter (7.9 ± 0.5 mg mL−1). These measurements were repeated after 24 h to screen the stability of the resulting emulsions. Solubility screening of Celecoxib in different oils was performed with a slightly modified saturation shake‐flask method27-29: in a 2 mL sample vial an excess of Celecoxib was added to 1 mL oil. However, boots baby lotion n oil work best for caucacians because they are not produced for the African skin though some pple might be lucky to have a good result with them. Prior to diluting the samples, the anhydrous formulations were visually examined for homogeneity and phase separation. Read full Disclaimer & Disclosure statements here. The presence of exogenous lipids in the duodenum stimulates the secretion of bile which contains phospholipids, cholesterol, and bile salts.4 The increased concentration of bile provides an emulsifying environment rich in micelles, into which lipids, the lipid digestion products and any available drug are solubilized.4, 12, 15-17 In the duodenum, pancreatic lipase then hydrolyses the remaining triglycerides to monoglycerides (MAGs), DAGs, i.e., partial glycerides that have a better capacity for drug solubilization and emulsification than their triglyceride counterparts18 and FFAs that may function as cosurfactants.12 Since there is evidence that (mixtures of) MCTs, MAGs, and DAGs have a higher solubilization capacity than LCTs, controlled modification of SB and PKO may result in new derivatives with desirable properties for the delivery of poorly soluble drugs. Overall, the majority of lipids available around the globe is rather unexplored in terms of their applicability in lipid‐based delivery systems. Hence, we aimed for enzymatic modification of these starting materials by using two different concepts for the synthesis of desired lipids. 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). Working off-campus? Experiments were performed as follows: first, in a 20 mL glass beaker, a 1:1 mixture (1.5 mL of each) of Tween 20 and Kolliphor RH 40 was prepared.
