The inventions by Parx Plastics to create a powerful and safe method to inhibit the growth of bacteria combines an innovative method for preparation with the clever use of one of the most abundant trace elements in the human body. We incorporate this element inside the polymers. We do not integrate it as a nanoparticle.

The characteristic of a nanoparticle allows it to come out of the material and transfer to the ambient, where it can be inhaled or digested while the effects in the product deteriorates. We feel there are too many downsides and perhaps dangers to the use of nanoparticles so we truly incorporate our feature in the polymer. It becomes one with the polymer without the dangers of exiting the material. Furthermore the polymers characteristics remain untouched. No change is made to their mechanical and physical property and even after mechanical stress, variations of temperatures and light exposure there is no degradation of the antiseptic effect. The effect lasts a lifetime.

During the research and discovery of our technology we thoroughly analyzed the natural processes and the way our world has found a correct balance to maintain a healthy biodiversity; the result of our efforts has been an incredibly efficient biocompatible technology against gram+ and gram- bacteria’s without cytotoxicity for human cells and without the use of biocides.

Sanipolymers developed by Parx Plastics have these characteristics:


Parx Plastics makes use of the natural trace element that is an essential mineral of exceptional biologic and public health importance.


Parx Plastics does not use silver or Nano-silver to achieve the antibacterial/antimicrobial effect. Silver is toxic and the use of Nano-silver can be hazardous as nanoparticles can come loose from the materials and inhaled or digested while their antibacterial property remains.


No Triclosan is used to achieve the antibacterial/antimicrobial effect. Triclosan is a toxic/pesticide. The use of Triclosan is regulated in the USA and EU and currently under review by the FDA and Health Canada. The use of Triclosan in food packaging is not allowed in EU. Triclosan penetrates the skin on contact and enters the bloodstream.


The Parx Plastics solution is not on a Nano scale. The disadvantage of Nanoparticles is that they can leave the material they have been integrated in and the function degrades over time. Our solution is not in Nano scale, so cannot leave the material and therefor cannot be inhaled or digested and the function does not degrade over time.


The technology is incorporated in the plastic, so it is not a coating. The function is through and through in the material. So it is not just on the surface and the great advantage is that it cannot wear off.


Our materials are created by means of innovative technology and methods with the clever use of one of the most important natural trace elements, which is securely incorporated inside the material without the possibility of exiting the material.


Parx Plastics makes use of innovative technologies and newly discovered methods in combination with one of the most important natural trace elements. We do not use chemicals or pesticides.


Our technology cannot escape from or exit the material like nanoparticles can. So it does not loose effectiveness and the technology does not wear out.


Temperature does not impact the functionality of our technology.


The shape or form of a part created with our materials does not impact the function of the material.


Light or the absence of light does not influence the functionality of our technology.


Our technology is fully ROHS compliant.


Our technology meets the applicable EU directives for food contact material.


As Sanipolymers™ proof to show no migration, there is no FDA clearance needed when applied in plastics that come in contact with foodstuff.


Substances used in relation to our technology are all authorized substances for the use in plastics. So no limitations are applicable.

The European Commission has announces Parx Plastics as one of Europe’s TOP 3 Startups.
The European Commission’s vice-president Neelie Kroes introduced the Tech All Stars competition by urging the backing of Europe’s young startups “Europe has the talent. It needs founders like you to believe it. It’s you who can come up with the good ideas and shake it all up. Start forging tomorrow’s economy. Create the jobs. Change the world. Because that’s what startups and entrepreneurs do.”

Antibacterial: a global interest

Controlling the breeding of bacteria has now reached global awareness and will be the main focus in the consumer market for upcoming years. Antibacterial and antiseptic objects would not only help reducing risks in underdeveloped countries, but shows to be a valuable precaution and contribution to the (food) safety in the modern world.

In this context Parx Plastics has done extensive biomimetic research in cooperation with renown universities, and has been able to find a unique way to create Sanipolymers™. Plastic objects created with Sanipolymers™ thus obtain functionalities to effectively inhibit the growth of bacteria up to 98-99% according to ISO 22196 tests.


In the current market products with antibacterial properties are available achieved by means of nanosilver. But Nano-silver is expected to be put on regulatory procedures in the USA and in Europe as the dangers of this non-biocompatible material are brought to the attention of the public by health and environmental watchdog groups. The EU has legislation in preparation restricting the marketing of products enhanced by Nano-silver.

Nano materials are often defined as being between 1 and 100 nanometers (a nanometer is one billionth of a meter) and among researchers the biggest fear is that Nano-silver could escape from its intended products. Then Nano-silver could easily be ingested or inhaled into the human body while still remaining its antibacterial properties. The risks of this for the human health has not yet been extensively researched but the experts’ hypotheses are enough for creating legislation. Especially as the market sees an increase in the demand for antibacterial items the need is felt to restrict the use of nanosilver.

  • Silver is toxic to all living cells
  • Silver contributes to antibiotic resistance
  • Nano-silver is still in Nano scale and comes out of the materials
  • Nano-silver can be digested or inhaled and will for example be in peoples lungs while their antibacterial property remains
  • Silver disturbs bacterial activity when cleaning sewage
  • Because of rapid increase of the use of Nano-silver, more regulations and laws are being created to abandon Nano-silver
“The estimated yearly growth of the antimicrobial market is 40%, and silver is marketed as an alternative to antibiotics. However, bacteria can become resistant to both silver and antibiotics, and the use of silver can actually mediate the antibiotic resistance. The medical consequences of the use/misuse of silver cannot be underestimated.”

“In its opinion on toxicity aspects of nano silver, the Federal Institute for Risk Assessment (BfR) had recommended to waive the use of nano silver in foods and articles of daily use…”

  • Triclosan is a poison to human health, plants, animals and the environment as a whole (ecotoxic)
  • Triclosan degrades with light in dioxin and other chlorinated priority pollutants
  • Triclosan give bioaccumulation
  • Risk of development of resistance
  • Triclosan is under review by FDA and Health Canada
  • In the EU Triclosan may not be used for food contact materials
“Animal studies have shown that triclosan alters hormone regulation.” & “Other studies in bacteria have raised the possibility that triclosan contributes to making bacteria resistant to antibiotics.”

FDAU.S. Food and Drug Andministration

“Given the rapidly developing scientific database for triclosan, the Agency intends to accelerate the schedule for the registration review process for this chemical. Currently, the Agency intends to begin that process in 2013, ten years earlier than originally planned.”

EPA – United States Environmental Protection Agency

According to the European Commission, Scientific Committee on Consumer Safety there are several reasons why the use and release of triclosan into the environment could pose a risk:

  • Bacteria exposed to low concentrations of triclosan could activate resistance genes that they could in principle transfer to other bacteria.
  • Triclosan, like any other biocide, contributes to the selection of more resistant bacteria, because it eliminates competition.
  • Resistance to triclosan could lead to resistance to other biocides or antibiotics.
