Silica Gel Orange
Aharnish Desiccant offers Silica Gel Orange, a high-performance, self-indicating desiccant known for its exceptional moisture-absorbing capacity. Infused with an organic indicator, Silica Gel Orange can absorb up to 40% of its weight in moisture, ensuring superior moisture control for a wide range of applications.
- Cobalt-free, non-toxic indicator
- Orange-to-green colour change
- Free from chlorides and sulfates
- Safe for pharma and diagnostics
Overview
This non-toxic and pollution-free desiccant complies with industry standards and regulations, making it an ideal choice for safe and environmentally responsible moisture management. As it absorbs moisture, the silica gel undergoes a gradual color change, starting from orange to yellow and eventually transitioning to green once it reaches its full moisture capacity, providing a clear visual indication for easy monitoring.
Our Silica Gel Orange is free from foreign impurities such as chlorides, sulfates, and other contaminants, ensuring high adsorption efficiency and consistent performance throughout its lifespan. It is widely used in industries requiring precise moisture control.
At Aharnish Desiccant, we ensure the supply of high-quality Silica Gel Orange in both bead and crystal forms, suited to a variety of commercial and industrial needs.

Silica Gel Orange — questions & answers
Yes. Orange silica gel uses a non-toxic organic indicator instead of cobalt chloride, so it is the preferred self-indicating desiccant for pharmaceutical, diagnostic and food-adjacent applications where cobalt-based indicators are restricted.
It starts orange when dry, shifts to yellow as it adsorbs moisture, and turns green once it reaches full moisture capacity — giving a clear, staged visual indication of remaining service life.
Yes. Reactivate it by heating at 100–120°C until it returns to its original orange colour, then cool it in a sealed container. It can be reused through multiple cycles.
It is commonly specified for pharmaceutical packaging, diagnostic kits, food containers, transformer breathers, optical instruments and electronic components — anywhere a cobalt-free indicating desiccant is required.

Silica Gel Blue
At Aharnish Desiccant, we offer premium-quality Silica Gel Blue, a synthetic, amorphous form of silicon dioxide embedded with cobalt chloride as a moisture indicator. This self-indicating desiccant exhibits a distinct color change—appearing deep blue when dry and gradually turning pink as it absorbs moisture. Once the material is saturated, the pink hue indicates the need for regeneration or replacement.
Silica Gel White
At Aharnish Desiccant, we offer premium-grade Silica Gel White, a highly effective moisture-absorbing agent ideal for use in high-humidity environments, particularly above 50% relative humidity. This non-reactive, physically adsorptive desiccant draws in water vapor through its intricate network of internal pores, without undergoing any chemical changes or producing harmful by-products.
