The current status of controversy regarding the use of certain preservatives in cosmetic products makes it necessary to seek new ecol. alternatives that are free of adverse effects on users. In our study, the natural terpene thymoquinone was encapsulated in chitosan nanoparticles. The nanoparticles were characterized by DLS and TEM, showing a particle size of 20 nm. The chem. structure, thermal properties, and release profile of thymoquinone were evaluated and showed a successful stabilization and sustained release of terpenes. The antimicrobial properties of the nanoparticles were evaluated against typical microbial contaminants found in cosmetic products, showing high antimicrobial properties. Furthermore, natural moisturizing cream inoculated with the aforementioned microorganisms was formulated with thymoquinone-chitosan nanoparticles to evaluate the preservative efficiency, indicating its promising use as a preservative in cosmetics. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Recommanded Product: 31566-31-1).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 31566-31-1

Effects of Glyceryl Monostearate on the Retrogradation of Pea Starch was written by Wang, Ling;Lan, Xuyue;Xu, Wen;Du, Qinling;Deng, Sha;Jia, Dongying. And the article was included in Starch/Staerke in 2022.Recommanded Product: Glyceryl monostearate The following contents are mentioned in the article:

Pea starch (PS) jelly is prone to retrograde, resulting in increased hardness and decreased taste. Based on this, the effects of glyceryl monostearate (GMS) on the retrogradation properties of pea starch are investigated. The rheol., texture, thermal, mol., and crystal properties of PS-GMS blends are studied, and the possible interaction between PS and GMS is also analyzed. The addition of GMS reduces the hardness of pea starch gel, increases its springiness, and improves its quality. As the concentration of GMS increases, the onset temperature, conclusion temperature, and gelatinization enthalpy of the blend gels decrease. Moreover, GMS also reduces their ordered structure and crystallinity. The changes in the storage modulus after the addition of NaCl and urea indicate that GMS interactes with amylose mainly through hydrogen bonding. It can be concluded that GMS inhibits the retrogradation of PS gel by interacting with amylose through hydrogen bonds. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Recommanded Product: Glyceryl monostearate).

The aim of this study was to combine fluconazole (FZ)-loaded solid lipid nanoparticles (FZ-SLNs) and chitosan films (C-films) for the potential administration of FZ across the buccal mucosa using a Box-Behnken design. The chitosan films containing FZ-SLNs (C-FS-films) and C-films were prepared using a film casting method. The ATR-FTIR anal. confirmed the presence of hydrogen bonds between the NH⁺₃ groups of chitosan and the OH or COO^– groups of glyceryl monostearate in the films. Addnl., FESEM anal. of the morphol. of C-FS-films revealed the presence of FZ-SLNs in the films. Permeation studies using porcine buccal mucosa demonstrated that FZ from the C-FS-films was more permeable than in C-films. The antifungal activity of the C-FS-films was evaluated against Candida albicans, and inhibition zones were observed Thus, C-FS-films represent an exciting drug carrier for the treatment of candidiasis via the buccal mucosa.

For metabolome sample preparation, rapid quenching of cellular metabolism without severe loss of intracellular metabolites is important. Here, we comparatively evaluated the two sampling methods, cold methanol quenching and fast filtration, for one of the most important industrial microorganisms, yeast Saccharomyces cerevisiae. The latter, using a vacuum manifold system capable of processing up to twenty samples simultaneously, was developed here. The results showed that the cold methanol quenching method resulted in severe losses of intracellular metabolites but that sugars and sugar phosphates were highly preserved. In comparison, the fast filtration method better preserved most metabolites with less extracellular contamination. Our results suggested that the fast filtration method with a vacuum manifold system can be widely applied to yeast metabolome anal. due to its simplicity, robustness, and lack of significant intracellular metabolite loss.

And the article was included in International Journal of Biological Macromolecules in 2022.Name: Glyceryl monostearate The following contents are mentioned in the article:

Edible double network oleogels were prepared by hydroxypropyl methylcellulose (HPMC) and glyceryl monostearate (GMS) by the cryogel-templated method. Hot GMS soybean oil solutions were absorbed by HPMC cryogels, which were further homogenized and cooled to form oleogels containing both the HPMC network and GMS network. The crystal network constructed by GMS crystal clusters significantly enhanced the mech. and rheol. attributes of oleogels. Both the HPMC network and the GMS network were built up due to hydrogen bonds. According to the normalization anal. of FTIR and the deepening of the shift of the absorption peak, hydrogen bonds could also be formed between HPMC and GMS to connect the two independent networks. Double network oleogels were further used to fabricate cookies and cakes, assessed by the texture profile anal. The combination of the HPMC network and GMS network in preparing oleogels will promote the application of oleogels as the fat replacer.

Physicochemical properties and oxidative stability of duck fat-added margarine for reducing the use of fully hydrogenated soybean oil was written by Shin, Dong-Min;Yune, Jong Hyeok;Kim, Tae-Kyung;Kim, Yea Ji;Kwon, Hyuk Cheol;Kim, Do Hyun;Jeong, Chang Hee;Choi, Yun-Sang;Han, Sung Gu. And the article was included in Food Chemistry in 2021.Recommanded Product: Glyceryl monostearate The following contents are mentioned in the article:

Soybean oil (SBO) and fully hydrogenated soybean oil (FHSBO) have been used for margarine production However, SBO-based margarine requires a considerable amount of trans fatty acid-containing FHSBO due to its low m.p. We aimed to reduce the FHSBO content in margarine by employing duck fat, which has a higher m.p. than SBO. Margarines were prepared using different ratios of duck fat and reduced levels of SBO and FHSBO. Physicochem., sensory, and oxidative properties of the margarines were evaluated. The quality characteristics of margarine improved when duck fat replaced SBO and FHSBO. Furthermore, the lipid oxidation parameters were lower in duck fat-added margarines than the control during storage at 60°C for 28 days. The margarine containing 80% duck fat showed the best sensory properties. Collectively, duck fat can replace SBO in margarine while reducing the use of FHSBO and maintaining desirable physicochem. properties, oxidative stability, and sensory properties.

Insights into the formation and digestive properties of lotus seed starch-glycerin monostearate complexes formed by freeze-thaw pretreatment and microfluidization was written by Ou, Yujia;Wei, Zhixi;Jiang, Xiangfu;Wu, Guoyan;Xie, Wen;Zheng, Baodong;Zeng, Hongliang. And the article was included in International Journal of Biological Macromolecules in 2022.Recommanded Product: 31566-31-1 The following contents are mentioned in the article:

The objective of this paper was to investigate the formation and digestive properties of lotus seed starch-glycerin monostearate complexes (LSG) formed by freeze-thaw pretreatment and microfluidization. The results showed that the preparation of LSG with six freeze-thaw cycles at 60 MPa had the highest complex index (69.92%). The formation of LSG led to the conversion of the crystalline pattern of lotus seed starch from C-type to V-type and increased the proportion of the microcrystalline region. In addition, the digestive results indicated that LSG had a high resistance to digestive enzymes, which was conducive to increasing the content of resistant starch. Based on the above investigation, the formation and digestive properties showed that the appropriate number of freeze-thaw cycles of pretreatment could facilitate the complexation of starch and lipid under low-pressure microfluidization, which made for the directional regulation of helical conformation and anti-digestion.

The synthetic chems. in food contact materials can migrate into food and endanger human health. In this study, the traveling wave collision cross section in nitrogen values of more than 400 chems. in food contact materials were exptl. derived by traveling wave ion mobility spectrometry. A support vector machine-based collision cross section (CCS) prediction model was developed based on CCS values of food contact chems. and a series of mol. descriptors. More than 92% of protonated and 81% of sodiated adducts showed a relative deviation below 5%. Median relative errors for protonated and sodiated mols. were 1.50 and 1.82%, resp. The model was then applied to the structural annotation of oligomers migrating from polyamide adhesives. The identification confidence of 11 oligomers was improved by the direct comparison of the exptl. data with the predicted CCS values. Finally, the challenges and opportunities of current machine-learning models on CCS prediction were also discussed.

The aims of this study were to develop a nanostructured lipid carrier (NLC) system and optimize an appropriate NLC formulation using design of experiments (DOE). The results showed that the formulation containing glycerol monostearate (GMS) 0.35 g, stearic acid (SA) 0.50 g and iso-Pr myristate (IPM) 0.65 g was optimal with entrapment efficiency (%EE) (59.21%), particle size (233.7nm) and zeta potential (-41.26 mV). Moreover, solid lipid (GMS, SA) and liquid lipid (IPM) had significant impact on NLC characteristics. The pos. effect on the %EE was due to the interaction between GMS and IPM, and SA and IPM. The optimal formulation EWH-NLC at concentration 125 μg/mL expressed the highest inhibitory activity against NO production in RAW 264.7 macrophages with no cytotoxicity. The release profile of EWH-NLC in the cream base exhibited sustained release behavior that best fitted with Higuchi model. These results suggest that the NLC is a suitable carrier for EWH in topical application with a sustained-release profile.
