Phytaxyl. [Serobiologiques] SD alcohol 39-C, barley extract propylene glycol, polysorbate 20. 

Annatto extract is sold ia several physical forms, including dry powders, propylene glycol/monoglyceride emulsions, oil solutions and suspensions, and alkaline aqueous solutions containing anywhere from 0.1—30% active colorant calculated as bixia, norhixin, as appropriate. It... 

The course of the fermentation is tested by removal of samples, which are extracted with methyl isobutyl ketone. The extract is analyzed by paper chromatography in a system of dioxane toluene/propylene glycol. 

Plant extracts containing xanthophyll diesters are saponified in composition of propylene glycol and aqueous alkali to form crystals crystallization of xanthophylls is achieved without use of organic solvents crystals are isolated and purified Xanthophylls obtained from corn gluten meal at 50 C using ethanol with ethoxyquin as antioxidant...

Cellulose gum, Irish moss extract, and propylene glycol alginate are the hydrocolloids most of en used in this application at levels of between 0.25 and 1%, depending on the fruit-sugar ratio and the type of fruit. 

The product reacts slightly acid. If an entirely neutral /-propylene glycol is desired, the syrup first obtained should be made neutral with a solution of sodium methylate in methyl alcohol, and again concentrated and extracted as indicated. 

The first chapter followed a nontraditional path in polyurethane chemistry. We first assumed the role of an environmental chemist seeking to develop a solid extraction solvent to remove pollutants from water and air. We chose to use polyalcohols because of the spectrum of polarities they possess. Using ethylene and propylene glycol, one can design an extractant system by varying the amount of each compound in a block or random polymer.

Ambrette Seed Oil occurs as a clear yellow to amber liquid with the strong, musky odor of ambrettolide. It is a volatile oil obtained by steam distillation from the partially dried and crushed seeds of the plant Abeltnoschus moschatus Moench, syn. Hibiscus abeltnoschus L. (Fam. Malvaceae). It is refined by solvent extraction to remove fatty acids or by precipitation of the fatty acid salts. It is soluble in most fixed oils and in mineral oil, often with cloudiness, but relatively insoluble in glycerin and in propylene glycol. 

Balsam Pem Oil occurs as a yellow to pale brown, slightly viscous liquid having a sweet, balsamic odor. It is obtained by extraction or distillation of Pemvian Balsam obtained from Myroxylon pereirae Royle Klotzsche (Fam. Leguminosae). Occasionally, crystals may occur within the liquid. It is soluble in most fixed oils, and is soluble, with turbidity, in mineral oil. It is partly soluble in propylene glycol, but it is practically insoluble in glycerin. 

Note If the aqueous extract contains more than 20 mg of glycerin or more than 30 mg of propylene glycol, dilute the extract in a volumetric flask and transfer a suitable aliquot into a 500-mL glass-stoppered Erlenmeyer flask before proceeding with the test. The weight of the sample should be corrected in the calculation.
