Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Synthetic Route of 111-90-0.
Ma, Qiuyan;Zhang, Jing;Lu, Bohong;Lin, Huaqing;Sarkar, Rajib;Wu, Tao;Li, Xuee research published 《 Nanoemulgel for Improved Topical Delivery of Desonide: Formulation Design and Characterization》, the research content is summarized as follows. This research aimed to develop a novel drug delivery system to improve treatment of skin disorders. The system is comprised of a Carbopol 980-based nanoemulgel (NE-gel) containing a desonide (DES; 0.05%, weight/weight) nanoemulsion (NE), which has a small particle size, high encapsulation efficiency, good thermodn. stability, good permeation ability, and high skin retention. DES-loaded NE (DES-NE) was prepared by high-pressure homogenization. The developed formulation was characterized by differential scanning calorimetry (DSC), X-ray diffraction, drug release, skin permeation, and drug retention. DES in vitro release and skin permeation studies with different formulations of artificial membrane and rat abdominal skin were performed with the Franz diffusion cell system. Confocal laser scanning microscopy (CLSM) was used to detect the localization and permeation pathways of drugs in the skin. Compared with com. available gel (CA-gel) and NE, the NE-gel release process conformed to the Higuchi release model (R2 = 0.9813). NE-gel prolonged the drug release time and allowed for reduced administration dose and frequency. The unit cumulative permeation of NE and NE-gel through the skin for 12 h was 63.13 ± 2.78 and 42.53 ± 2.06μg/cm2, resp., values significantly higher (p < 0.01) than that of the CA-gel (30.65 ± 1.25μg/cm2) and CA-cream (15.21 ± 0.97μg/cm2). The DES-NE and DES NE-gel skin drug retention was significantly higher than com. available formulations (p < 0.01). Hence, the prepared NE-gel is a potential vehicle for improved topical DES delivery for better treatment of skin disorders.
Synthetic Route of 111-90-0, Diethylene glycol monoethyl ether appears as a colorless, slightly viscous liquid with a mild pleasant odor. Flash point near 190°F. Used to make soaps, dyes, and other chemicals.
Diethylene glycol monoethyl ether is a primary alcohol that is ethanol substituted by a 2-ethoxyethoxy group at position 2. It has a role as a protic solvent. It is a diether, a primary alcohol and a hydroxypolyether. It derives from a diethylene glycol., 111-90-0.
