The cosmetic industry is one of the fastest growing industrial sectors that is constantly evolving by absorbing new technologies and incorporating innovative yet sustainable products. Cosmetic products are comprised of diverse formulations such as skin care, color cosmetics, hair care, makeup, body care products. Traditionally, cosmetic emulsions are stabilized using surfactants or polymers. Due to its adverse effects on environment, cytotoxicity effects, numerous health hazards, there is a strong drive to shift towards sustainable and surfactant free emulsions. With increasing consumer demand for a safer and more biodegradable products, formulating “surfactant- free” emulsions by replacing conventional stabilizers with particles has gained popularity. In this review, various important aspects and applications of particle stabilized emulsions in cosmetic formulations will be discussed. Importantly, novel ideas on surface modification of particles and use of Janus particles in cosmetic formulations will be discussed.

化妆品行业是发展最快的工业部门之一，通过吸收新技术并整合创新而可持续的产品而不断发展。化妆品由多种配方组成，例如皮肤护理，彩色化妆品，护发，彩妆，身体护理产品。传统上，使用表面活性剂或聚合物来稳定化妆品乳液。由于其对环境的不利影响，细胞毒性作用，许多健康危害，因此有很强的动力向可持续和不含表面活性剂的乳液转变。随着消费者对更安全，更可生物降解的产品的需求不断增长，通过用颗粒代替传统的稳定剂来配制“无表面活性剂”的乳液越来越受欢迎。在这篇评论中 将讨论颗粒稳定乳液在化妆品配方中的各个重要方面和应用。重要的是，将讨论有关颗粒表面改性和Janus颗粒在化妆品配方中的使用的新颖思想。
