Sensory texturizing agents in cosmeceuticals: Navigating the skin-bioactive interface and recent advancements

The quest for perfect skin has long captivated humanity, blending art and science in elegant alchemy of cosmeceuticals products that promise not only beauty but tangible therapeutic transformation. Central to these products are texturizing agents or rheology modifiers that govern viscosity, thixotropy, spreadability, and sensory perception while ensuring emulsion stability and controlled release of actives. Traditionally, synthetic polymers like carbomers, acrylates copolymers, and silicones have dominated due to their unparalleled robustness, pH independent thickening, and viscoelastic properties in complex oil in water and water in oil systems. However, escalating regulatory scrutiny, microplastic concerns, and clean beauty movement have accelerated a transition toward natural and bio based alternatives, reflecting a broader shift from synthetic to sustainable paradigms in cosmeceutical design. Recent advances showcase polysaccharides, microbial exopolymers, and plant derived biopolymers achieving rheological profiles rivaling synthetics, often with superior skin compatibility, biodegradability, and ecofriendly life cycle impacts. Hybrid and bio engineered modifiers like modified cellulose (e.g. EcoFlexy) and fermented polymers (e.g. hyaluronic acid), modified konjac glucomannan (e.g. Inagel Green), exemplify this convergence, offering high performance thickening with natural origin and enhanced sensory attributes. Hence, this review combines the latest evidence on mechanisms, safety performance metrics highlighting opportunities in biotechnology driven texturizers to resolve the texture absurdity and propel cosmeceuticals toward high efficacy formulations.
