Recent Developments Related to the Formulation of Water-in-Oil-in-Water (W/O/W) Emulsions with Improved Emulsion Stability …Paul Thau
F
or over fifty years, numerous publications have been written and patents issued related to multiple emulsions, particularly W/O/W emulsions. This interest stems from the significant applications of these complex emulsion systems to entrap watersoluble materials, particularly as topical delivery systems for controlled and sustained release of active ingredients. These emulsions are of practical use to formulators working in the areas of pharmaceuticals, cosmetics, food chemistry, and agriculture. Despite numerous attempts, cosmetic chemists were unsuccessful in formulating multiple emulsions with acceptable stability at room temperature and 40 ºC until the last twenty years. A major factor for this achievement has been the synthesis and commercial availability of a group of lipophilic polymeric emulsifiers, most of which have molecular weights in excess of 5000. The objective of this review article is to document the progression of advances for the use of these new emulsifiers, in conjunction with our understanding for the use of specific stabilizing additives, associated with improved understanding of colloid chemistry and knowledge about processing techniques to produce a W/O/W emulsion with acceptable stability at all standard temperature conditions.
Background information Multiple W/O/W emulsions are composed of aqueous droplets, which are dispersed inside oil drops. These oil droplets are themselves dispersed in an external aqueous phase. There are two interfaces in these complex systems. A hydrophobic emulsifier with a low HLB value stabilizes the first one and a hydrophilic emulsifier with a high HLB is present at the second interface.1 Potential applications for multiple emulsions include uses for cosmetic, pharmaceutical, and food products. Most of these uses
are aimed for slow and sustained release of active ingredients from an internal reservoir into the continuous aqueous phase. They can also improve dissolutions or solubilization of insoluble materials. Due to these properties, multiple emulsions find applications related to protecting sensitive and active molecules such as vitamins C and E from the external phase. Numerous patents related to the use of multiple emulsions for special applications, including protecting

the stability of sensitive active ingredients have been issued. Despite the sustained release and protective properties of multiple emulsions in protecting ingredients from degradation, on a practical level significant problems may arise due to thermodynamic instability and a strong tendency for coalescence, flocculation, and creaming. In addition, the stability of W/O/W emulsions may be affected by a number of factors, including the method of preparation, the osmotic balance between the internal and external water phase, the phase volume ratio, and the type and concentration of the emulsifier.3 Until twenty years ago, most studies relating to multiple emulsions were based on conventional nonionic surfactants. However, most of these surfactant systems were reported to produce multiple emulsions with limited emulsion stability.4 In contrast, several new types of polymeric emulsifiers, when appropriately formulated with good processing techniques, were demonstrated to significantly improve the physical stability of multiple emulsions.5 Schematic illustration of a W/O/W double emulsion Based on detailed studies of the preparation of droplet. Originally printed in Reference 11. stable W/O/W multiple emulsions, T. Tadros advises that the following conditions should be fulfilled. A) Two emulsifiers, one with a low and another with a high HLB should be used. One emulsifier should be used to produce the primary W/O emulsion and the other for the W/O/W multiple emulsion. B) Polymeric emulsifiers that provide steric stabilization are necessary to maintain long-term physical stability. C) An optimum osmotic balance between the internal water droplets and the outer continuous phase is recommended.3,5 A publication by A. Kovács, entitled “Structural analysis of W/O/W emulsions by means of DSC,” provides useful information related to investigating the complex and variable structures of W/O/W emulsions.1 His studies include microscopic observations combined with differential scanning calorimetric (DSC) measurements in order to identify the formed structure at development stages in case of different components, preparation methods, and stirring rates. It was concluded that multiple emulsions prepared with non-polar lipophilic agents contained fewer multiple droplets than those containing polar agents, at constant surfactant concentration. This observation was confirmed both by microscopic analysis and DSC studies. In addition DSC studies were found to be an adequate tool for the following:1 1. Quantitatively measure the mass fraction of different aqueous phases. 2. Detect the relationship between the stirring rate and the mass fraction of inner aqueous droplets. 3. Give feedback for the formulation technology, by characterizing the structure of multiple emulsions. 4. Follow the micro-structural changes occurring during storage. The authors of this publication recommended that the next stage of investigation should be to analyze the rheological behavior and the drug release profile of the multiple emulsion compositions.1 A 2009 publication by D.D. Vasiljevic et al., entitled “Rheological and droplet size analysis of W/O/W multiple emulsions containing low concentrations of polymeric emulsifiers,” is noteworthy since it provides significant pathway related information related to the formulation of functional W/O/W emulsions with improved stability at room temperature and 40 ºC.3 “In this study, W/O/W multiple emulsion systems containing low concentration levels of lipophilic polymeric emulsifiers, cetyl dimethicone copolyol and PEG-30 dipolyhydroxystearate, were evaluated. The concentrations of the primary emulsifiers were set at 1.6 and 2.4% w/w in the final emulsions. Rheological and droplet size analysis of the investigated samples showed that the type and concentration of the primary emulsifiers markedly affected the characteristics of the multiple emulsions. The multiple emulsion prepared with 2.4% w/w of PEG-30 dipolyhydroxystearate as the primary emulsifier exhibited the highest apparent viscosity, yield stress, and elastic modulus values, as well as the smallest droplet size. Furthermore, these parameters remained relatively constant over the study period, confirming the high stability of the investigated sample. The results obtained indicate that the changes observed in the investigational samples over time can be

attributed to the swelling/breakdown mechanism of the multiple droplets. Such changes could be adequately monitored by rheological and droplet size analysis.” Based upon their extensive studies, the authors of this meritorious publication stated that semi-solid W/O/W emulsions based on lipophilic polymeric emulsifiers offered potential advantages as a vehicle for dermatological and cosmetic preparations.

Theoretical explanation for the superiority of polymeric emulsifiers versus low molecular weight monomeric emulsifiers for the preparation of W/O/W emulsions In an article published in a text, entitled “Multiple Emulsions Stabilized by Biopolymers,” published in 2008, the authors (Lutz and Aserin) explained that monomeric emulsifiers can migrate from the W/O interface to the oil phase, and the hydrophilic surfactant can be transported to the inner interface and alter the required hydrophilic/hydrophobic balance of each of the phases. In contrast, polymeric amphiphiles are known to be multi-anchoring amphiphiles with irreversible adsorption capabilities that can improve the droplets interfacial coverage during emulsification. Since they provide strong steric stabilization capabilities they are able to form thick and flexible films that in most cases are anchored into the oil-water interface. Droplet size reduction and increased shelf-life stability is achieved with the use of polymeric amphiphiles.6

Role of electrolytes in improving stability of W/O/W emulsions The inclusion of electrolytes (sodium chloride, magnesium sulfate, etc.) in the external water phase of W/O/W emulsions plays an important role in the stability of multiple emulsions by balancing the osmotic pressure between the oil, internal, and external phases.7 Rationale for the use of W/O/W multiple emulsions as a means of prolonged delivery of drugs The drug contained in the innermost phase is forced to partition itself through several phases prior to release at the adsorption site. Thus, the partition and diffusion coefficient of the drug and strength of the middle membrane phase, which is a multi-molecular layer of oil, water, and emulsifier, at both the interfaces of multiple emulsion systems, controls the drug release from these systems.8,9 (Continued on page 6)

General information related to W/O/W multiple emulsions Oil phase components: As a general rule, mineral oils produce more stable multiple emulsions than those produced from vegetable oils. The order of decreasing stability and percentage of entrapment has been found to be light liquid paraffin > squalene > sesame oil > maize or peanut oil.10 Rheological evalution: The rheology of multiple emulsions is an important parameter as it is related to emulsion stability and performance properties. The viscosity and interfacial elasticity are two major parameters, which relate to product rheology.10 Viscosity measurement: It is recommended that the viscosity be measured by a Brookfield rotational viscometer. Samples are sheared for one minute at 100 rpm, using an appropriate spindle.10 Interfacial rheology: An oscillatory surface rheometer is recommended for this measurement.10 Use application for multiple emulsions: Employed to protect natural colorants A recently filed U.S. Patent Application, entitled “Multiple Emulsions for Colorants,” provides an interesting example for the utility of multiple emulsions in protecting ingredients prone to oxidation and exposure to light.11 The abstract for this application reads as follows:
The Soul & Science of Beauty. www.evonik.com/personal-care
“The present invention is related to a multiple emulsion of water-in-oil-in-water (W/O/W) type for stabilization of natural coloring agents, such as anthocyanin, phycocyanin, carthamus, huito, calcium carbonate, carmine, and carminic acid, against changes in pH values, oxidation, and light as well as against ingredient interactions. The inventors of the present invention have surprisingly found that the stability of natural coloring agents can be increased by dispersing the waterdispersible coloring agents as W/O/W multiple emulsions. Especially, the pH stability of the natural coloring agents is increased considerably by encapsulation in a W/O/W multiple emulsion allowing for the result.” Polyglycerol polyricinoleate is the low HLB polymeric emulsifier described in this patent application used for a multiple emulsion composition to protect a variety of natural colorants from oxidation. Prototype W/O/W emulsion exhibiting stability and light skin feel The following prototype W/O/W emulsion, submitted for publication in 2005 by Uniqema Inc., illustrates some of the techniques employed in recent years to formulate W/O/W emulsions with improved stability and light skin feel.12 The formulation composition consists of a low HLB polymeric emulsifier, selection of lipophilic oils and esters, and inclusion of an appropriate concentration of electrolyte.

Caveats and recommendations Despite recent advances made since the availability of lipophilic polymeric emulsifiers for the formulation of W/O/W emulsions, one of their drawbacks continues to be limited long-term stability. Publications that report on the use of multiple emulsion technology for food, pharmaceutical, dermatological, and cosmetic applications provide information related to additives, stabilizers, and processing methodologies to enhance formulation stability and efficacy.13-16 A publication authored by Figen Tirnaksiz et al., entitled “A topical W/O/W multiple emulsion prepared with poloxamine 908 as a hydrophilic surfactant: Formulation, characterization and release study,â€? provides useful information particularly related to stability of W/O/W emulsions after extended stability testing at 40 ÂşC and room temperature.15 The formulations studied are shown below, together with stability information.

The formulations containing 1% cetyl dimethicone copolyol and 1 or 2% poloxamine 908 were the most stable of those tested. However, it should be noted this stability profile would not be acceptable for most cosmetic and dermatological formulations considered for commercialization. Since the stability of multiple emulsions is influenced by numerous formulation and process variables, achieving formulations with longer-term stability will depend on further advances in our knowledge of these variables and the use of stabilizing agents. Conclusion With the introduction of a range of lipophilic polymeric emulsifiers during the past twenty years, the feasibility for successfully formulating stable and functional W/O/W emulsions has increased; however, formulating W/O/W emulsions exhibiting longer-term stability at elevated temperatures continues to be a challenge. It is anticipated that this complex emulsion delivery system will gain increased usage for development of topical delivery compositions for prolonged release of active agents, incorporation of incompatible materials, and protection of active ingredients by dispersion in the internal phase of W/O/W emulsions.
