近年来，在许多工业应用中，对基于非表面活性剂的皮克林乳液的需求显著增长，因为选择可生物降解和低毒性的可持续材料作为乳液稳定剂。通常，乳液是一种分散系统，其中合成的表面活性剂或大分子稳定了两个不混相（通常是水和油相），以防止聚并。然而，合成表面活性剂在某些应用中并不总是合适的选择，特别是在制药，食品和化妆品中，由于毒性和缺乏相容性和生物降解性。因此，本综述报告了最近（2018-2021）关于在各种皮克林乳剂配方中使用相对安全的可生物降解多糖颗粒、蛋白质、脂质及其组合的文献。此外，还概述了与这些固体颗粒的功能化或表面改性相关的各种可调因素，这些因素决定了皮克林乳液的稳定性。在皮克林乳状液中，固体颗粒积聚在两个不混相之间的界面上，通过形成物理屏障来减少聚并。使用生物衍生颗粒来生产更可持续的皮克林乳剂正变得越来越流行。
In recent years, the demand for non-surfactant based Pickering emulsions in many industrial applications has grown significantly because of the option to select biodegradable and sustainable materials with low toxicity as emulsion stabilisers. Usually, emulsions are a dispersion system, where synthetic surfactants or macromolecules stabilise two immiscible phases (typically water and oil phases) to prevent coalescence. However, synthetic surfactants are not always a suitable choice in some applications, especially in pharmaceuticals, food and cosmetics, due to toxicity and lack of compatibility and biodegradability. Therefore, this review reports recent literature (2018–2021) on the use of comparatively safer biodegradable polysaccharide particles, proteins, lipids and combinations of these species in various Pickering emulsion formulations. Also, an overview of the various tuneable factors associated with the functionalisation or surface modification of these solid particles, that govern the stability of the Pickering emulsions is provided. In a Pickering emulsion, solid particles accumulate at the interface between two immiscible phases to reduce coalescence by forming a physical barrier. Using bioderived particles is becoming popular to generate more sustainable Pickering emulsions.
