I am looking for biodegradable oil in water and water in oil emulsifier that can be used for food, medicines, and cosmetics.
Dear Zoraida,
The following text describes some of biodegradable natural emulsifiers used in food and cosmotics.
1-In personal care product Saponins are naturally occurring compounds found in a vast number of plant species. Some of the more recognizable plants containing saponins include: quinoa, oats, soy, yucca, quillaja, soapwort, and soap berries. Saponins are classified as glucosides, where hydrophobic alcohols consisting of (sapogenin) and a sugar side chain, joined by an ether bond. The carbohydrate moiety consists of pentoses, hexoses, or uronic acids. The presence of both polar (sugar) and nonpolar (steroid or triterpene) groups provide saponins with strong surface-active properties. Their physiochemical and biological properties feature structural diversity, which have led to a number of traditional and industrial applications. Many saponins are added to shampoos, liquid detergents, toothpastes, and beverages as both an emulsifier and as a long-lasting foaming agent.
2-Natural compound that have made great strides toward the «perfect» naturally derived surfactant are alkypolyglucosides (APGs).
3-lecithins are wide use in food and cosmetic industry. They are group of phospholipids that are found in many plant and animal tissues. they are extracted from soybean, sunflower, egg or milk are an interesting option for green product formulators, and these have long been considered natural, especially coming from the food industry.

Green Cosmetic Surfactant from Rice: Characterization
and Application
Ibrahim Hanno 1 , Marisanna Centini 2,*, Cecilia Anselmi 2 and Claudia Bibiani 3
Abstract: During recent years, microwave irradiation has been extensively used for
performing green organic synthesis. The aim of this study was to synthesize, through a microwave-assisted irradiation process, a natural surfactant with O/W emulsifying properties. Our attention was focused on polyglycerol esters of fatty acids that are biocompatible and biodegradable non-ionic surfactants widely used in food and cosmetic products. The emulsifier was obtained using vegetable raw material from renewable sources: polyglycerol derived from vegetable glycerol and rice bran oil fatty acids. The natural emulsifier obtained was then characterized and evaluated for its emulsifying properties using different doses, oil phases, rheological additives, waxes, etc. The potential application in solar products, in comparison with other natural emulsifiers, was also evaluated.
Keywords: natural surfactants; rice bran oil; polyglycerol esters; microwave irradiation

Hi Rafik,
Thank you for your articulate response. This is very useful.
