# Sanitary Pads Raw Material Composition and Properties

Sanitary pads are essential personal care products designed to provide comfort and hygiene during menstruation. The effectiveness and comfort of these products largely depend on the raw materials used in their construction. Understanding the composition and properties of these materials is crucial for both manufacturers and consumers.

## Core Components of Sanitary Pads

The primary raw materials used in the production of sanitary pads include:

– Top Sheet: This is the layer that comes in direct contact with the skin. It is usually made from a non-woven fabric that is soft, breathable, and quick-drying.
– Absorbent Core: The core is responsible for absorbing menstrual fluid. It is typically composed of a blend of wood pulp and superabsorbent polymers (SAP).
– Back Sheet: This layer prevents leakage and is usually made from a polyethylene film that is impermeable to liquids.
– Adhesive: Adhesives are used to secure the pad to the underwear. They are designed to be strong enough to hold the pad in place but gentle enough to avoid skin irritation.

## Properties of Raw Materials

Each component of a sanitary pad has specific properties that contribute to the overall functionality and comfort of the product:

– Top Sheet: The top sheet must be soft to prevent irritation and allow for quick absorption of menstrual fluid. It should also be breathable to reduce the risk of skin irritation and discomfort.
– Absorbent Core: The core needs to have high absorbency to manage menstrual flow effectively. The combination of wood pulp and SAP ensures that the pad can hold a significant amount of fluid without leaking.
– Back Sheet: The back sheet must be impermeable to prevent leaks while being flexible enough to move with the body. It should also be quiet to avoid any noise during use.
– Adhesive: The adhesive should provide a secure fit without causing discomfort or leaving residue on clothing. It must also be hypoallergenic to minimize the risk of allergic reactions.

## Environmental Considerations

With increasing awareness of environmental issues, there is a growing demand for eco-friendly sanitary pads. Manufacturers are exploring alternative materials such as biodegradable plastics, organic cotton, and plant-based SAP to reduce the environmental impact of these products. These materials not only offer similar performance but also decompose more quickly in the environment, making them a more sustainable choice.

## Conclusion

The raw materials used in sanitary pads play a critical role in their performance and user comfort. By understanding the composition and properties of these materials, consumers can make informed choices, and manufacturers can continue to innovate and improve their products. As the demand for eco-friendly options grows, the industry is likely to see more advancements in sustainable materials, further enhancing the quality and environmental impact of sanitary pads.
