Technical Details & Test Data
- Processing of SIPERNAT® PC
SIPERNAT® PC Hydrated Silica exfoliating particles are tailored to cover the full range of scrub formulations, enabling different desquamation and sensory properties. The SIPERNAT® PC portfolio offers particles in different size, morphology and hardness that enable formulations for skin areas of different sensitivity (e. g. face, body, feet). The synthetic mineral nature of SIPERNAT® PC Hydrated Silica provides for consistent and high quality, reducing the microbiological burden in the formulations to a minimum. The hydrophilic surface of the SIPERNAT® PC Hydrated Silica particles not only makes them easy to incorporate into any type of scrub formulations but also ensures removal in waste water treatment after application. This makes SIPERNAT® PC an eco-friendly alternative for microplastic. SIPERNAT® PC Hydrated Silica due to its close relation to natural occurring silica is recognized as nature identical by major certification organizations, e.g. COSMOS

SIPERNAT® 250 PC and SIPERNAT® 9000 PC are composed of exceptionally sturdy round-edged Hydrated Silica particles and are therefore the preferred choice for formulations with a long lasting scrubbing effect. The large SIPERNAT 9000 PC particles are selected for strong desquamation or for the function of a sensory indicator when combined with smaller particles for the cleaning. SIPERNAT® 22 PC and SIPERNAT® 2200 PC both feature spherical and softer particles, providing for a gentle cleaning. With its small and soft particles, SIPERNAT 22 PC is specially recommended for its efficient but gentle desquamation. SIPERNAT® 2200 PC with the bigger particles leads to a more pronounced particle sensation in the formulations. As its particles disintegrate while rubbing on skin the product is a preferred choice when gentle cleansing is desired, e.g. for sensitive formulations.
Processing of SIPERNAT® PC
Hydrated Silica- Incorporate SIPERNAT® PC Hydrated Silica at low to moderate shear to prevent the destruction of the particle at any time during processing.
- Typical use concentration is 5 to 10 w.-%. Please note that for the same number of particles higher concentrations of SIPERNAT® PC products with bigger particle size are needed.

Storage & Handling
- Shelf Life
- 24 months
- Storage Conditions
Our silica products are inert and extremely stable chemically. However, due to their high specitic surtace area, they can absorb moisture and volatile organic comoounds from the surrounding atmosphere. Therefore, we recommend storing the products in sealed containers in a dry, cool place, and removed from volatile organic substances. Even if a product is stored under these conditions, after a longer period it can still pick up ambient moisture over ume, which could lead to is exceeding the specitied moisture content. For this reason, our recommended use-by date is 24 months after date of manuracture. Product more than 4 months old should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.
