Silica Beads are COSMOS approved micro beads, used as a Mattifying Agent and for Oil Absorption.

These are widely used for Make-Up, Colour Cosmetics, Baby Care and various Skin Care Applications.

Exceptional Moisture Control

Silica beads deliver superior moisture absorption due to their porous structure-capable of holding 20-40% of their weight in water. They are widely used as desiccants in packaging, electronics, pharmaceuticals, and food storage, ensuring sensitive products remain dry and uncontaminated throughout their shelf life.

Robust and Safe Design

The beads are renowned for their strong mechanical strength and low attrition, making them durable for repeated use after regeneration. They are chemically inert, non-toxic, and compliant with important safety regulations (RoHS, REACH), providing peace of mind when used in environments where safety and purity are paramount.

Easy Regeneration and Versatile Application

Silica beads can be regenerated and reused by heating at 110-120C for 2-3 hours. Available in a variety of packaging options, they serve multiple applications-from industrial drying processes to moisture protection in packed goods-making them a versatile solution for humidity control.

FAQ's of Silica Beads:

Q: How do silica beads function as a desiccant?

A: Silica beads work by absorbing moisture from their surroundings through their porous structure, effectively lowering humidity levels inside packaging or storage areas. This helps protect products from spoilage, degradation, or corrosion caused by excess moisture.

Q: What is the process for regenerating silica beads for reuse?

A: To regenerate silica beads, heat them at 110-120C for 2-3 hours. This process drives off the absorbed water, restoring their desiccant capacity and allowing them to be reused multiple times.

Q: When should I replace or regenerate silica beads in use?

A: Regeneration or replacement is required when the beads become saturated and lose their moisture-absorbing capacity. Color-indicating variants will change from blue or orange to another color, signaling it is time to regenerate or replace them.

Q: Where can silica beads be applied effectively?

A: Silica beads are utilized in diverse settings including packaging, electronics storage, pharmaceuticals, food preservation, and air or gas drying, where maintaining dry conditions is critical for product integrity.

Q: What are the benefits of using silica beads in packaging and storage?

A: Silica beads help prevent mold, corrosion, and spoilage by controlling moisture levels, extending the shelf life and quality of stored or shipped products, and maintaining their usability.

Q: How should silica beads be stored for optimal shelf life?

A: Store silica beads in tightly sealed containers in a cool, dry place. Proper storage can extend their shelf life up to two years, preserving their effectiveness as a desiccant.

Q: Are silica beads safe to use with food and pharmaceuticals?

A: Yes, silica beads are non-toxic, chemically inert, odorless, tasteless, and compliant with RoHS and REACH directives, making them suitable for use in food packaging and pharmaceutical applications.
