Sanitary Pad Materials: Composition and Properties

Sanitary pads are essential hygiene products used by millions of women worldwide. Understanding the materials that make up these pads is crucial for both comfort and health. This article explores the composition and properties of sanitary pad materials, shedding light on their functionality and benefits.

Core Components of Sanitary Pads

Modern sanitary pads consist of multiple layers, each serving a specific purpose:

• Top Layer (Coverstock): Usually made from non-woven fabric or perforated plastic film, this layer allows quick absorption while keeping the surface dry.
• Absorbent Core: Typically composed of wood pulp, superabsorbent polymers (SAP), or a blend of both, this layer traps and retains fluid.
• Back Sheet: A waterproof layer, often made of polyethylene, prevents leaks and keeps moisture from reaching clothing.
• Adhesive Strip: Found on the underside, this ensures the pad stays securely in place.

Properties of Sanitary Pad Materials

The materials used in sanitary pads are carefully selected for their unique properties:

1. Absorbency

The absorbent core, particularly SAP, can hold many times its weight in liquid, making it highly effective for menstrual flow management.

2. Breathability

Modern top layers are designed to allow air circulation, reducing moisture buildup and discomfort.

3. Softness

The top layer is often treated to be gentle on skin, minimizing irritation during prolonged wear.

4. Odor Control

Some pads incorporate materials with odor-neutralizing properties or include fragrance additives.

Emerging Material Innovations

Recent developments in sanitary pad technology include:

• Biodegradable materials like bamboo fiber or organic cotton for eco-friendly options
• Antibacterial treatments to reduce infection risks
• Thinner yet more absorbent cores for improved comfort

Understanding these materials helps consumers make informed choices about the products they use, balancing comfort, protection, and environmental impact.
