Summary

This review examines the role of polymeric rheology modifiers in emulsion-based cosmetics such as skin and hair care products. The study discusses how various polymers are used to stabilize cosmetic emulsions and achieve desirable flow characteristics, providing context for understanding the types of synthetic polymers commonly used in personal care formulations.

Body Systems

Emulsions play a crucial part in the whole beauty and care market, especially in skin and hair care domains where, due to their extraordinary versatility, they represent most of the finite products. Being thermodynamically unstable, one key aspect of their formulation is the use of stabilizers that ensure a long lifetime under different conditions. In this framework a key role is related to rheology modifiers, which include all those raw ingredients added to achieve, among others, desirable inflow characteristics that would not be possible to gain in their absence. In this review, strong attention was dedicated to different polymers and formulation strategies to understand the key role of these ingredients, widely used in emulsion-based cosmetics formulations.
