Occludents refers to substances or agents that have the ability to prevent or restrict the evaporation of moisture or the movement of air through a physical barrier. These substances are commonly used in various field applications such as cosmetics, pharmaceuticals, and materials science.
In the field of cosmetics and skincare, occludents are often included in products like moisturizers, creams, and balms to form a protective film on the skin's surface. This film acts as a barrier that minimizes water loss by reducing transepidermal water loss (TEWL). Occludents effectively lock in moisture within the skin, keeping it hydrated for longer periods and preventing dryness.
Pharmaceutical formulations also utilize occludents to enhance drug delivery methods and improve the efficacy of certain medications. By creating a barrier on the skin, occludents can slow down the evaporation of volatile medicinal compounds, ensuring their prolonged contact with the affected area and facilitating absorption.
Furthermore, occludents find applicability in materials science, where they are used to create impermeable layers in various contexts. These impermeable layers can prevent the passage of air, water, or other substances through a material, providing resistance to moisture, weathering, and other external factors.
Overall, occludents are substances that possess the ability to form a barrier, restricting the movement of air or moisture. Their wide utilization across different industries showcases their significance in maintaining skin health, enhancing drug delivery, and providing protective properties to materials.
