Preparation of radioactive diacetyl, acetoin, and 2,3-butylene glycol
Analytical Biochemistry, 1981Abstract Toluene-treated cells of Streptococcus diacetilactis produced large amounts of diacetyl and acetoin without 2,3-butylene glycol. With Na-[3-14C]pyruvate added to reaction mixtures in place of unlabeled pyruvate, diacetyl with specific activity of 6.1 × 104 cpm/μmol and acetoin with specific activity of 6.8 × 104 cpm/μmol were harvested ...

The bacterial formation of acetylmethyl-carbinol and 2:3-butylene glycol
Biochimica et Biophysica Acta, 1952Abstract The formation of acetylmethyccarbinol and 2:3-butylene glycol has been studied using washed cell suspensions of Aerobacter aerogenes. The results show marked differences in the production of the two four-carbon compounds from glucose and pyruvic acid and make it improbable that a simple decarboxylation of pyruvic acid to acetaldehyde ...

High molecular weight biodegradable polyesters were prepared from sebacic acid, ethylene glycol and butylene glycol through a simple non-solvent polycondensation with a low toxicity catalyst. The successful synthesis of the polyesters was confirmed by gel permeation chromatography, (1)H-nuclear magnetic resonance and Fourier transform-infrared ...

Case of allergic contact dermatitis due to 1,3‐butylene glycol
The Journal of Dermatology, 2014Abstract1,3‐Butylene glycol (1,3‐BG) is widely used in cosmetics, including low‐irritant skin care products and topical medicaments, as an excellent and low‐irritation humectant. We report a case of allergic contact dermatitis caused by 1,3‐BG. A 28‐year‐old woman suffered from an itchy erythematous eruption on her face.

Butylene Glycol, Hexylene Glycol, Ethoxydiglycol, and Dipropylene Glycol are viscous liquids used in the cosmetic industry as humectants, emulsifiers, plasticizers, and solvents. The results of acute, subchronic, and chronic oral toxicity studies using a variety of animal species indicate a low order of toxicity for the Glycols ...
