in silica™ Improve your high-value ingredients
- extended release of perfumes & actives
- stabilization of sensitive actives
- suitable for novel formulations
How to improve a high-value ingredient
1. You provide the ingredient or mixture
2. SiliCycle adapts the process according to your purposes and specifications, and generates optimal sphere-shaped composite material (1 to 100 microns spheres loaded with up to 75 % of ingredient).
3. Your ingredient, sequestered in silica microspheres is promptly shipped to you, along with characterization data.
4. The improved ingredient is yours, ready to be tested, formulated and commercialized.



Selected Attributes
in silica™ can improve hydrophobic and hydrophilic sensitive ingredients, volatiles, essential oils, synthetic fragrances with the following benefits:
- protection against degradation
- slow release for increased safety and efficiency (progressive desorption, indirect contact)
- flexibility in formulation of unstable, oxidable or viscous ingredients (incorporating lipophilic actives in aqueous formulations)
- modulated desorption for novel olfactory experiences (variation in duration, intensity and desorption order)
- ingredient’s integrity (no heating involved)
- cost-efficiency gains (less material for desired activity level)
- Silica-made
- Porous microspheres
- Ingredient sequestered during synthesis
- Environment-friendly
- Polymer
- Core-shell capsules
- Impregnation
- Regulatory banned
- Nanoparticle
The in silica™ Process
Main Attributes of in silica™
Stability of sensitive compounds
Degradation kinetics: Rétinol véritable™, hydrophilic silica sequestering retinol, oil, tocopherols and ascorbyle palmitate

Modulated liberation of compound
Modulation of the liberation kinetics in the destination environment (here, a hydrophilic compound in water)

Integrity of cargo
Modulation of the liberation kinetics in the destination environment (here, a hydrophilic compound in water)

Slow release of compound
Significantly delay in the release of a volatile compound (here, an essential oil exposed to air at ambient temperature)

Chemical versatility
Compounds from a wide range of chemical families can be sequestered

Multiple uses
Hydrophobic and hydrophillic compounds for numerous product classes can be sequestered:
- Vitamins
- Fragrances
- Vegetal natural oils
- Cooling agents (ex: menthol)
- Dyes
- Essential Oils
- Perfumes
- Animal natural oils
- Heating agents (ex: capsaicin)
- Sunscreens
