Synthesis and biodegradation testing of some synthetic oils based on ester [PDF]

open access: yesScientific Reports
Synthetic ester oils are widely used in many applications due to their ideal cleaning properties, lubricating performance and assured polarity. The majority of esters oils are more biodegradable. than any other base stock.

Studies on Surfactants, Cosurfactants, and Oils for Prospective Use in Formulation of Ketorolac Tromethamine Ophthalmic Nanoemulsions

open access: yesPharmaceutics, 2021
Nanoemulsions (NE) are isotropic, dispersions of oil, water, surfactant(s) and cosurfactant(s). A range of components (11 surfactants, nine cosurfactants, and five oils) were investigated as potential excipients for preparation of ketorolac tromethamine (

Synthesis and Characterization of High Glycolic Acid Content Poly(glycolic acid-co-butylene adipate-co-butylene terephthalate) and Poly(glycolic acid-co-butylene succinate) Copolymers with Improved Elasticity

open access: yesACS Omega, 2023
Poly(glycolic acid) (PGA) is a biodegradable polymer with high gas barrier properties, mechanical strength, and heat deflection temperature. However, PGA's brittleness severely limits its application in packaging, creating a need to develop PGA-based copolymers with improved elasticity that maintain its barrier properties and hydrolytic degradability ...

Propylene and butylene glycol: new alternatives to ethylene glycol in conjugated polymers for bioelectronic applications

open access: yesMaterials Horizons, 2022
Propylene and butylene glycol oligoether chains have been employed as alternatives to ethylene glycol in thiophene based semiconductors for OECTs. Their impact on electrochemical, microstructure, and swelling properties are discussed.

Condensation of 4-azafluorene with ?-butylene glycol and glycerin

open access: yesChemistry of Heterocyclic Compounds, 1986
1,4-Di (4-azafluoren-9-yl) butane and 9-(δ-hydroxybutyl)-4-azafluorene were obtained by condensing 4-azafluorene with γ-butylene glycol. From the first of these products, 1,4-di(7-aza-3-oxo-1,2,3,10b-tetrahydrofluoranthen-10b-yl)butane was synthesized by a series of successive transformations (cyanoethylation, hydrolysis, dehydrocyclization).

Antibacterial and antifungal properties of propylene glycol, hexylene glycol, and 1,3-butylene glycol in vitro.

open access: yesActa Dermato-Venereologica, 1991
The antimicrobial properties of three glycols, - propylene glycol, hexylene glycol, and 1,3-butylene glycol - against Candida albicans, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes A, Streptococcus mitis, and E. coli were studied in vitro. Within 20 h, 10% and 30% hexylene glycol in fresh tryptic soy broth were able to kill

Microbial Production of 2,3-Butylene Glycol from Cheese Whey [PDF]

open access: yesApplied and Environmental Microbiology, 1982
Six microorganisms that produced acetoin or diacetyl or both from glucose were tested for the production of 2,3-butylene glycol from lactose. Bacillus polymyxa and Streptococcus faecalis gave positive results and were tested in unmodified wheys. Cottage cheese whey was unsatisfactory, but
