Formulation and Characterization of a multiple Emulsion containing Vitamin - C

Abstract

Multiple Mixes have been proposed to have multitudinous uses including their use for improvement of bioavailability or as a dragged medicine delivery system. But the essential insecurity of this system needs to be overcome before they find implicit operation in medicinals. Multiple mixes are frequently stabilized using a combination of hydrophilic and hydrophobic surfactants. The rate of these surfactants is important in achieving stable multiple mixes. The purpose of the study was to prepare a stable multiple conflation containing a skin anti-aging agent and using paraffin oil emulsion. Vitamin C, was incorporated into the inner waterless phase of water- in- oil emulsion- in- water (w/ o/ w) multiple conflation at a attention of 1. Multiple conflation was prepared by two step system. Stability studies were performed at different accelerated conditions, i.e. 8°C (in refrigerator), 25°C (in roaster), 40°C(in roaster), and 40°C at 75 RH (in stability cabin) for 28 days to prognosticate the stability of phrasings. The ideal of this study was to prepare multiple conflation of Ascorbic acid by two step emulsification using different non-ionic surfactants, Tweens and Agar, and estimate for stability, chance medicine ruse. The study concluded that stable multiple conflation with high ruse effectiveness can be prepared by two step emulsification system using agar- agar primary emulsifier and Tween 80 as secondary emulsifier. F2 formulation is the best formulation than the F1 and F3 formulations based on phase separation and other tests.

Formulation and Characterization of Double Emulsions W/O/W Stabilized by Two Natural Polymers with Two Manufacturing Processes (Comparative Study)

“…Herbert [14] emerged as a pioneer in 1965, utilizing multiple emulsions for the controlled release of drugs in pharmaceuticals [15,16]. Double emulsions can be used for the encapsulation of drugs like vitamins [17], vaccines [18], or even certain bioactive compounds extracted from plants [19]. The conception and development of hydrophilic drug distribution systems is an ongoing process in pharmaceutical research.…”
