Clean and pure: Our commitment to removing pesticides from your products

All types of oils can potentially contain pesticides, as pesticides are often used in agriculture to protect crops from insects, diseases, and other pests. Oils that are derived from crops that are commonly treated with pesticides, such as vegetable oils and fruit oils, are more likely to contain pesticides than oils derived from other sources.


Common oils that may contain pesticides:

  • Vegetable oils: Vegetable oils, such as soybean oil, corn oil, and canola oil, are often derived from crops that are treated with pesticides to protect against pests and diseases. These oils may therefore contain residues of pesticides.
  • Fruit oils: Fruit oils, such as citrus oil, olive oil and avocado oil, are also often derived from crops that are treated with pesticides. These oils may therefore contain traces of pesticides.
  • Animal oils: Animal oils, such as lard and tallow, may also contain pesticides if the animals were exposed to pesticides through their feed or the environment.
  • Essential oils: Essential oils, which are extracted from plants using steam distillation or other methods, may also contain pesticides if the plants were treated with pesticides.

Overall, any type of oil can potentially contain pesticides, and it is important to carefully check the source and quality of the oil to ensure that it is free of pesticides.


Reasons to remove pesticides from extracts and oils:

  1. Pesticides can be harmful to human health.
  2. Pesticides can affect the quality of extracts and oils.
  3. Pesticides can be harmful to the environment.
  4. Pesticides can lead to legal and regulatory issues.


Methods for removing pesticides from oils: adsorption, extraction, and chemical degradation

There are several methods that can be used to remove pesticides from oils, depending on the specific type of pesticide and the characteristics of the oil. Some of the key methods for removing pesticides from oils include the following:

  • Adsorption: Adsorption is a process in which pesticides are removed from the oil by binding to a solid adsorbent material, such as activated carbon or clay. The adsorbent material is mixed with the oil, and the pesticides are attracted to the surface of the adsorbent, where they are retained. The adsorbent material can then be removed from the oil using filtration or centrifugation.
  • Extraction: Extraction is a process in which pesticides are removed from the oil by mixing the oil with a solvent, such as hexane or ethanol. The solvent dissolves the pesticides, which are then separated from the oil using techniques such as distillation or filtration.
  • Chemical degradation: Chemical degradation is a process in which pesticides are broken down into smaller, less toxic compounds using chemical reactions. This can be achieved using a variety of chemicals, such as oxidizing agents or enzymes, depending on the specific type of pesticide.

At SpinChem, we have a wealth of experience in selecting the most effective solid adsorbent materials for removing pesticides from oils. We understand that different adsorbent materials are better suited for different types of pesticides and oils, and we use our expertise to carefully select the right material for the job.

Our team of scientists and engineers has extensive knowledge of the properties and characteristics of different adsorbent materials, and we use this knowledge to carefully evaluate the options and make informed decisions. We also conduct rigorous testing to ensure that the selected material is effective at removing pesticides from the oil, and we regularly review and update our selection process to ensure that we are using the most advanced and effective materials available.

Examples of pesticides that has been efficiently removed are: 

  • myclobutanil
  • malathion
  • spinosad
  • acequinocyl
  • and more...

By using our expertise in selecting solid adsorbent materials, we are able to provide our customers with oils that are free from pesticides and other contaminants, while maintaining the integrity and quality of the finished product. We are committed to delivering the highest quality products to our customers, and we believe that our careful selection of solid adsorbent materials is a key factor in achieving this goal.

Application 1008
Activated carbon decolorization, fast and without filtration

Activated carbon is a common choice for removing impurities or capturing compounds from a product batch. However, the carbon may itself foul the product and be difficult to separate. The rotating bed reactor offers a clean way to deploy activated carbon that removes the need for time-consuming filtration and extends the lifetime of the solid phase.  

Application 1035
Dramatically improved deionization with a rotating bed reactor

Removing ions from liquids is common in industry and society. Ions are remediated in applications ranging from the production of pharmaceuticals to the treatment of communal waste streams. Likewise, the nuclear energy sector deals with the removal of ionic radioactive substances from water on a daily basis.

Application 1024
Decolourization more efficient in rotating bed reactor than in fixed bed reactor

A fixed bed reactor (FBR), also known as a packed bed reactor or column, is a traditional technology for processes such as adsorption or heterogeneous catalysis. Achieving the required level of purification or conversion means running the liquid through the reactor at a sufficiently low flow rate, and the throughput of a fixed bed reactor is therefore often limited.

Application 1026
Decolourization with activated carbon in a production scale rotating bed reactor

The rotating bed reactor (RBR) is a clean way to use activated carbon for purification, which eliminates the need for time-consuming filtration and extends the lifetime of the solid phase. It is available on scales ranging from milliliters to hundreds of cubic meters and offers faster decolorization, elimination of filtration, and extended adsorbent lifetime.

Application 1045
Pesticide remediation in extracts and oils

Pesticide residue can ruin a batch of a botanical extract, creating large problems for producers. Curated adsorbents, specifically chosen for your situation, can be used to remediate the pesticides. With a rotating bed reactor, you are equipped to respond to contaminants showing up on your test results.

Exploring the effectiveness of different types of activated carbon

Contaminations in liquids can often be removed using an adsorbent, such as granular activated carbon (GAC). The best choice of adsorbent is unique for each contaminant, and the effectiveness depends on many parameters. Failing to investigate these can lead to unnecessarily high material costs and long processing times.

Application 1048
Heavy metal remediation in extracts and oils

Plants accumulate heavy metals from the soil in which they grow, and consequently the metals are found in any extracts produced from them. If the soil contains high levels of heavy metals, the resulting concentrate may be unfit for human consumption, and need remediation.
