ABSTRACT: Halobetasol propionate (HP) is an ultra-potent corticosteroid used in management of severe and recurrent cases of Atopic Dermatitis (AD). The marketed cream formulations are based on synthetic surfactants which often aggravate AD. The present studies investigate biocompatible pluronic lecithin organogel (PLO) of Halobetasol propionate in management of AD. Methyl propionate, also known as methyl propanoate, is the organic compound with the molecular formula CH 3 CH 2 CO 2 CH 3. It is a colorless liquid with a fruity, rum-like odor. Preparation. Methyl propanoate can be prepared by esterification of propionic acid with methanol.
MDL: MFCD00055235 Synonyms: 2-Bromo-2-methylpropionic Acid Isopropyl Ester, Isopropyl 2-bromoisobutyrate Isobutyl propionate appears as a colorless liquid. Less dense than water. Vapors heavier than air. May be mildly toxic by ingestion, inhalation and skin absorption.

Synthetic flavoring substances and adjuvants may be safely used in food in accordance with the following conditions. (a) They are used in the minimum quantity required to produce their intended effect, and otherwise in accordance with all the principles of good manufacturing practice. (b) They consist of one or more of the following, used alone or in combination with flavoring substances and ISOPROPYL PROPIONATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Updated use levels and food categories collected as part of the FDA’s SLR project are available from the FEMA office for this flavor ingredient upon request.
