Abstract
Polysaccharides, polynucleotides, and polypeptides are basic natural polymers. They have various applications based on their properties. This review mostly discusses the application of natural polymers as emulsion stabilizers. Natural emulsion stabilizers are polymers of amino acid, nucleic acid, carbohydrate, etc., which are derived from microorganisms, bacteria, and other organic materials. Plant and animal proteins are basic sources of natural emulsion stabilizers. Pea protein-maltodextrin and lentil protein feature entrapment capacity up to 88%, (1–10% concentrated), zein proteins feature 74–89% entrapment efficiency, soy proteins in various concentrations increase dissolution, retention, and stability to the emulsion and whey proteins, egg proteins, and proteins from all other animals are applicable in membrane formation and encapsulation to stabilize emulsion/nanoemulsion. In pharmaceutical industries, phospholipids, phosphatidyl choline (PC), phosphatidyl ethanol-amine (PE), and phosphatidyl glycerol (PG)-based stabilizers are very effective as emulsion stabilizers. Lecithin (a combination of phospholipids) is used in the cosmetics and food industries. Various factors such as temperature, pH, droplets size, etc. destabilize the emulsion. Therefore, the emulsion stabilizers are used to stabilize, preserve and safely deliver the formulated drugs, also as a preservative in food and stabilizer in cosmetic products. Natural emulsion stabilizers offer great advantages because they are naturally degradable, ecologically effective, non-toxic, easily available in nature, non-carcinogenic, and not harmful to health.

A Review of Biopolymers’ Utility as Emulsion StabilizersNirmala Tamang 1, Pooja Shrestha 2 , Binita Khadka 2, Monohar Hossain Mondal 3,* , Bidyut Saha 4,* and Ajaya Bhattarai 1,*
Environmental pollution has become a major problem in the past decade, and the public has become aware of it, which has led to an increase in the demand for environmentally friendly products that utilize biopolymers, such as lipids, polysaccharides, and proteins, among others, that are inexpensive renewable raw materials that can be considered as an alternative to petroleum-based, non-biodegradable plastic products [105,106]
A number of biopolymer stabilizers have been found to be more effective in various industries, such as food, pharmaceuticals, and cosmetics, than synthetic emulsion stabilizers
