Ethers can again be classified into two varieties: if the alkyl or aryl groups are the same on both sides of the oxygen atom, 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. Then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers. Electric Literature of 111-90-0.
Singh, Tej Pratap;Ahmad, Farhan Jalees;Jain, Gaurav Kumar;Verma, Navneet research published 《 Formulation development and characterization of nanoemulsion-based gel for topical application of raloxifene hydrochloride》, the research content is summarized as follows. Nanoemulsion-gels are nanosized droplets, and thermodynamically stable oil-in-water dispersion. Raloxifene hydrochloride a selective estrogen receptor modulator currently its more research is being laid on in treatment of diseases in estrogen deficient postmenopausal women. The objective of this research was to formulate nanoemulsion-gel of raloxifene for topical delivery. The oil, surfactant and cosurfactant were selected on the basis of maximal solubility of raloxifene. The screening of surfactant and cosurfactant were on the basis of their emulsification efficacy with oil to form homogenization mixture on gentle shaking. The nanoemulsions were prepared by ternary phase diagram method using different ratio of oil and surfactant-cosurfactant mixture (Smix) and nanoemulsion region obtained by excel sheet design triangular software. The composition of the optimized nanoemulsion contains 0.072 %w/v raloxifene, 14.29 %volume/volume oil phase (Labrafil-M2125CS), 33.33%volume/volume Smix (Cremophor-RH40:Transcutol-P, 1:1), and 52.38%volume/volume distilled water. The optimized nanoemulsion was converted into gel form by addition of 1%w/v Carbopol-934. The formulation NEG2 possessed droplets size 56.73±0.58 nm, zeta-potential -22.20±0.02 mV, spreadability 18.35±0.45 gcm-1sec-1 and viscosity 98.54 ± 0.39 mPas. The ex vivo permeation of NEG2 (22.38%) was comparatively lower to the permeation of NE3 (26.68%). Also, flux of NEG2 (11.96 ± 0.4 μgcm-2h-1) significantly lower permeability than NE3(16.28 ± 0.7μgcm-2h-1). But nanoemulsion-gel form is maintained more effective concentration within skin due to adhesive nature of gel form remain contact on the applied area for a long duration. Nanoemulsion-gel found stable during six months. The outcome of this study points out the nanoemulsion-gel better than nanoemulsion because of adhesive nature and less permeability. Consequently, It maintain more raloxifene concentration at applied skin.
Electric Literature 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.
