Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Area of Science:

Pharmaceutical Sciences
Infectious Disease Control
Materials Science

Background:

Hand hygiene is a critical strategy for preventing the spread of infections, including COVID-19.
Instant hand sanitizers offer a convenient alternative to soap and water, especially when unavailable.
Alcoholic and alcohol-free hand rub gels are effective formulations for infection control.

Purpose of the Study:

To explore the properties and behaviors of hydrogels in hand rub formulations.
To understand the role of hydrogels in creating stable and effective sanitizing products.
To guide the development of new and improved hand rub gels considering various media and regulations.

Main Methods:

Review of hydrogel properties and their application in hand rub formulations.
Analysis of different gelling agents, including cellulose derivatives and synthetic polymers.
Consideration of hydrogel behavior in hydroalcoholic and aqueous systems.

Main Results:

Hydrogels are essential for stable, easily dispersible hand rub formulations with desirable sensory properties.
Various gelling agents exhibit different rheological properties and compatibility, particularly with alcohols.
Understanding these properties is key to optimizing hand rub gel performance.

Conclusions:

Hydrogel properties significantly impact the efficacy and user experience of hand rub gels.
Careful selection of gelling agents is necessary for developing high-performing alcoholic and alcohol-free sanitizers.
Development must align with international regulatory standards for disinfectants and sanitizers.
