IXPER® products, based on calcium and magnesium peroxides, are used to provide the performance benefits of hydrogen peroxide (oxygen release, bleaching, reduction of odors, oxidation), delivered in a stable, sparingly soluble powder form.
The intrinsic chemical stability and the thermal stability are excellent, whereas the solubility in water is very low.
These inorganic peroxides are fine powders that are very insoluble. In the presence of water at their natural pHs, these products decompose to release oxygen.
As the pH drops, these products become more soluble and generate progressively higher ratios of hydrogen peroxide (active oxygen) to gaseous oxygen. Under acidic conditions, the available oxygen can be liberated within minutes.
The characteristics of IXPER® products, and in particular their ability to release oxygen slowly, make them suitable for use in a wide range of applications.
IXPER® 75C is Solvay’s 75% Calcium Peroxide grade: a high quality powder used in a wide range of applications in environmental, seed coating and oil drilling markets.
IXPER® 75C FCC
IXPER® 75C FCC is Kosher, Halal certificated Calcium Peroxide grade. It meets US Food Chemical Codex 9th Edition requirements for use dough conditioning.
IXPER® 60C is Solvay’s 60% calcium peroxide grade: a fine, very pale yellow, odorless used in a wide range of applications in environmental, seed coating and oil drilling markets.
IXPER® 70CG is a granular grade of Calcium Peroxide: a unique material offered by Solvay. It is specifically designed to avoid dust generated from handling other Calcium Peroxide grades.
IXPER® 35M is a Magnesium Peroxide based fine white powder containing approximately 35% of active ingredient.
IXPER® 35M is mainly used as a source for slow release oxygen in soil and ground water remediation, oxygenation of the bottom of lakes and ponds as well as wastewater and effluents.
IXPER® 35M Magnesium Peroxide is not classified as hazardous for transport.
IXPER® 25M is a Magnesium Peroxide based fine white powder containing approximately 25% of active ingredient.
It is mainly used as a source for slow release oxygen in soil and ground water remediation, oxygenation of the bottom of lakes and ponds as well as wastewater and effluents.
IXPER® 30MG is a granular grade of Magnesium Peroxide: a unique material offered by Solvay.
It is specifically designed to avoid dust generated from handling other Magnesium Peroxide grades. Its chemistry is similar to that of IXPER® 35M powder but the formulation provides even lower solubility in water resulting in reduction in release rates of actives and extension of effectiveness over time.
Soil and Groundwater Remediation
IXPER® products can be used to accelerate the natural attenuation of contaminated soils in a cost-effective manner.
The capability of aerobic microbes to biologically degrade contaminants, such as petroleum hydrocarbons, can be limited by inadequate levels of oxygen.
IXPER® products ensure that adequate oxygen is present over an extended period time.
IXPER® products may be used for the treatment of grease traps to help reduce sulfide-based odors, caused by anaerobic conditions.
IXPER® products provide peroxide and oxygen, thereby oxidizing sulfide compounds, which may be present in the grease trap.
The alkalinity also helps saponify the grease and reduce its level in the grease trap.
IXPER® products can be used in oxygenating the lower parts of artificial or natural lakes, as well as wastewater and effluent.
Oxygen concentration near the bottom of the lakes can be very low and many methods of increasing dissolved oxygen are unsatisfactory either because they require excessive agitation, which moves nutrients to the surface encouraging algae growth, or because they do not ensure sufficient oxygenation.
By sinking to the bottom and releasing oxygen over a period of time, IXPER® products can provide a more satisfactory method of oxygenating the lower layers.
Low Oxygen in the soil can be generated in waterlogged soils due to heavy rainfall or bad irrigation techniques. Crops growing at high temperatures or under a lot of sunshine have very high oxygen demand at the roots.
Under these conditions, the lack of oxygen reduces root growth resulting in stunted growth, poor yields, lack of seed germination, etc.
IXPER® products can be used for soil amendment in agricultural, horticultural and forestry applications. These products slowly decompose in the moist soil, generating oxygen and the corresponding hydroxide. This can have the following advantages:
- Increase total soil microbial population
- Enhance enzyme diversity
- Speed aerobic and biological activities at high moisture conditions
- Support healthy roots by enhancing symbiotic fungi growth
- Maintain and protect healthy plant roots
- Improve the hydraulic conductivity of the soil allowing more efficient movement of oxygen and nutrients. This effect is especially useful in heavy soils
- Give plants the ability to absorb more water and nutrients and use them more efficiently
IXPER® 75C Calcium Peroxide is widely used in the baking industry in the US as a component of dough conditioners.
IXPER® 75C Calcium Peroxide acts by oxidation of sulfhydryl groups in gluten, reforming the disulfide bonds that were broken during the mechanical mixing of the dough.
This application is not allowed in the EU, China and other countries.
IXPER® products may be used in toothpaste formulations where they help clean teeth and improve oral hygiene.
IXPER® products may be incorporated in hair bleaching formulations together with other oxidizers such as persulfates.
IXPER® is widely used as a curing agent in one-part polysulfide-based anhydrous sealants.
It is activated by atmospheric moisture which initiates the generation of active oxygen from the IXPER® leading to the oxidation of polyhydrosulfides.
IXPER® is used as a source of oxygen in aluminothermic processes and in other metallurgical applications.
The addition of IXPER to aluminothermic mixtures assists in ignition at lower temperatures and increases the temperature of the melt, making it easier to separate the slag from the metal.
