Sanitary Pads Raw Material Composition and Properties

# Sanitary Pads Raw Material Composition and Properties

Sanitary pads are essential hygiene products used by millions of women worldwide. Understanding the raw materials that go into their production is crucial for both manufacturers and consumers. This article delves into the composition and properties of the raw materials used in sanitary pads.

## Core Components of Sanitary Pads

The primary raw materials used in sanitary pads include:

– Absorbent Core: Typically made from wood pulp and superabsorbent polymers (SAP).
– Top Sheet: Usually composed of non-woven fabric or perforated film.
– Back Sheet: Often made from polyethylene film to prevent leakage.
– Adhesive: Used to secure the pad to the underwear.

## Properties of Raw Materials

### Absorbent Core

The absorbent core is the most critical component of a sanitary pad. It is designed to quickly absorb and retain menstrual fluid. The combination of wood pulp and SAP ensures high absorbency and comfort.

### Top Sheet

The top sheet is in direct contact with the skin, so it must be soft, breathable, and hypoallergenic. Non-woven fabrics are commonly used because they are gentle on the skin and allow for quick absorption.

### Back Sheet

The back sheet is responsible for preventing leaks. Polyethylene film is widely used due to its waterproof properties and flexibility. It ensures that the pad remains discreet and comfortable during use.

### Adhesive

The adhesive used in sanitary pads must be strong enough to keep the pad in place but gentle enough to avoid skin irritation. It is usually a pressure-sensitive adhesive that can be easily removed without leaving residue.

## Environmental Considerations

With increasing awareness of environmental issues, manufacturers are exploring eco-friendly alternatives for sanitary pad raw materials. Biodegradable options, such as organic cotton and plant-based SAP, are gaining popularity. These materials not only reduce environmental impact but also offer a safer and more sustainable choice for consumers.

## Conclusion

Understanding the raw materials used in sanitary pads helps consumers make informed choices and encourages manufacturers to innovate and improve product quality. By focusing on the composition and properties of these materials, we can ensure that sanitary pads remain effective, comfortable, and environmentally friendly.
