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 components of sanitary pads include the top sheet, absorbent core, back sheet, and adhesive. Each of these components plays a vital role in the overall functionality and comfort of the pad.

### Top Sheet

The top sheet is the layer that comes into direct contact with the skin. It is typically made from non-woven fabric or perforated film. The material must be soft, breathable, and quick-drying to ensure comfort and prevent irritation.

### Absorbent Core

The absorbent core is the heart of the sanitary pad, responsible for absorbing and retaining menstrual fluid. It is usually composed of a blend of fluff pulp and superabsorbent polymers (SAP). Fluff pulp provides bulk and structure, while SAP enhances absorbency and retention.

### Back Sheet

The back sheet is the outermost layer of the sanitary pad, designed to prevent leakage. It is commonly made from polyethylene film, which is waterproof and flexible. Some back sheets are also breathable to enhance comfort.

### Adhesive

Adhesive is used to secure the sanitary pad in place within the underwear. It is typically a pressure-sensitive adhesive that is strong enough to hold the pad in place but gentle enough to be removed without leaving residue.

## Properties of Raw Materials

The raw materials used in sanitary pads must possess specific properties to ensure the product’s effectiveness and safety.

### Softness and Comfort

The top sheet and other materials in contact with the skin must be soft and non-irritating. This is crucial for preventing discomfort and skin irritation during use.

### Absorbency and Retention

The absorbent core must have high absorbency and retention capabilities to effectively manage menstrual flow. This ensures that the pad remains dry and comfortable throughout use.

### Leakage Prevention

The back sheet and overall design of the pad must prevent leakage, providing confidence and security to the user.

### Breathability

Breathable materials help to reduce moisture buildup and prevent odors, enhancing the overall comfort and hygiene of the pad.

### Hypoallergenic Properties

Given the sensitive nature of the skin in the intimate area, the materials used must be hypoallergenic to minimize the risk of allergic reactions.

## Conclusion

The raw materials used in sanitary pads are carefully selected to ensure comfort, absorbency, and safety. Understanding the composition and properties of these materials helps in appreciating the technology and innovation behind this essential hygiene product. As consumer demands evolve, manufacturers continue to explore new materials and technologies to enhance the performance and sustainability of sanitary pads.
