In recent years, interest in the class of water‐soluble polymers—hydrophobically modified alkali soluble emulsion (HASE)—has increased on a surprising scale. With respect to other associative polymers, they have several advantages in terms of cost and ease of handling and utilization. In addition, unlike the solvent‐based formulations, these water‐soluble systems do not contain volatile solvents and hence do not contribute to environmental problems. In solutions, HASE polymers form a transient network through molecular associations between the hydrophobic groups. Due to these hydrophobic interactions, they have been increasingly used as rheology modifiers for various applications, such as paints, cosmetics, and personal care and paper coating products. These associative polymers have an architectural richness that allows the fine tuning of several physicochemical properties, and their optimal use requires controlling polymer concentration, molecular weight, size of the hydrophobic groups, and characteristics of the polymeric backbone. We give an overview of several studies on HASE polymers reported in the literature, focusing on the molecular structure, the synthetic methodologies, and—more specifically—on the factors that affect the rheology of their aqueous mixtures. As a general rule for the optimal HASE design and formulative exploitation, we highlight that the hydrophobic hanging groups are responsible for the rheological changes in the liquid phase, while the steric hindrance of the polymeric backbone and of the hydrophobic groups causes the stiffness.

Polymers have been used extensively in personal care products. The polymers used in personal care products range from both synthetic and natural polymers. The high demand for using polymers in personal care products is mainly because it is easy to obtain various final performance product attributes just by altering the structures and properties of the polymers. One of the polymers used in personal care products is polyacrylates. The term “acrylates” is defined as non-cross-linked copolymers containing a combination of acrylic acid, methacrylic acid and their simple esters. Polyacrylates in personal care products play important roles as thickeners, rheological modifiers, media for delivery of active ingredients, film formers, emulsifiers, moisturisers, dispersants, waterproofers and conditioners. Their key functionalities include the ability to increase the viscosity of solutions, form physical gels, stabilise dispersions and emulsions, induce particle aggregation, solubilise hydrophobic compounds, modify surface properties and facilitate the controlled release of active compounds.
