HPMC as a Thickening Agent in Hand Sanitizers

Hand sanitizers have become an essential part of our daily lives, especially in the wake of the COVID-19 pandemic. These products help to kill germs and prevent the spread of diseases. One crucial component in hand sanitizer formulations is Hydroxypropyl Methylcellulose (HPMC), which serves as a thickening agent. In this section, we will explore the role of HPMC in hand sanitizer formulations and how it contributes to their effectiveness.

HPMC is a cellulose derivative that is commonly used in various industries, including pharmaceuticals and personal care products. In hand sanitizers, it acts as a thickening agent, giving the product a desirable consistency and texture. Without a thickening agent, hand sanitizers would be too runny and difficult to apply effectively.

The primary function of HPMC in hand sanitizers is to increase the viscosity of the product. This thickening effect allows the sanitizer to stay on the hands for a longer duration, ensuring better coverage and contact time with the skin. When applied, the sanitizer needs to remain on the hands for at least 20 seconds to effectively kill germs. The presence of HPMC ensures that the sanitizer adheres to the skin, preventing it from quickly evaporating or dripping off.

Furthermore, HPMC also enhances the overall sensory experience of using hand sanitizers. It provides a smooth and creamy texture, making the product more pleasant to apply.
