A revolutionary biocompatible & patented technology

The Parx technologies are incorporated in Saniconcentrates™ and these are made with the aid of our patented innovative techniques. The plastic receives an intrinsic change on micrometrical scale which results in antiseptic and antibacterial characteristics due to the improves mechanical/physical properties.

Using Saniconcentrates™ allows you to make the surface of your products more resistant to the attack by microbes and bacteria and make the surface more resistant to bio-film adhesion. Our technology delivers and antimicrobial performance of 99,9% or higher measures according to ISO 22196 or JIS Z2801. The technology does not rely on migration. The technology is not leaching out.

Saniconcentrates do not contain biocides. It mimics the defence mechanism of the human skin.

Saniconcentrates™ are produced with the aid of a bodies own trace-element, like it is present in the top layer of the human skin. In skin this trace-element is responsible for the defence mechanism agains bacteria and viruses. With the Parx technologies we create a similar defence mechanism in plastic and polymers.

No silver


Silver and Nano-Silver are the most common solutions used today to make products antimicrobial. But we have to realize that silver is toxic to all living cells and contributes to antibiotic resistance. Nano-silver particularly leaches out of the product so it can be inhaled or digested and silver affects our waste water treatment methods.

The Parx Plastics technology is not using any harmful substance. It is completely biocompatible, non-toxic and 100% safe.

Micrometrical scale


Nanoparticles are small, very small. So small that they cannot be controlled. That means they will always be able to exit the material they have been put into. Nano-particles can be really powerful and something powerful that cannot be controlled should be very well considered. 

For these reasons Parx Plastics is not using nano particles or nano materials. Our technology is in micrometrical scale, perfectly under control.

No biocides


The Parx technology allows you to make a change in the mechanical/physical surface property of a product. And this changed property results in an antibacterial performance of 99,9% and higher.

We are not using biocides or pesticides, and we are not using silver, nano-silver, nanoparticles, Triclosan or any other harmful substance. We cleverly use one of the most abundant trace elements in the human body to create a surface that act against bacteria in a mechanical/physical way.

No Migration

No leaching required

The technology realises an intrinsic, inert property change in and on the surface of the material. There is no migrating principle that creates the antimicrobial effect. The technology is intrinsic in the material.


Saniconcentrates™ allow you to reduce the amount of bacteria on the surface of a product/material by 99,9%* or more.

Clean, hygienic, protected and above all: safe and sustainable

*proven by independent tests according to ISO 22196 and JIS Z2801





Only the natural trace element Zinc; an essential mineral present in food, necessary in our daily diet as it is vital for the human immune system.

No migration

An intrinsic, inert change in and on the surface of the material. There is no substance migrating or leaching to act against bacteria. The functionality is purely due to the improved mechanical/physical characteristics.


We do not use silver or Nano-silver. Silver is toxic and the use of such an ion-release mechanism can be hazardous as these elements can be inhaled or digested while their antibacterial property remains.


No Triclosan, quaternary ammonium salts, pyrithione or any other harmful or toxic chemicals.


Our technologies are on a micrometrical scale. We do not use nanoparticles or nano-materials. Nanoparticles will leave the material they have been integrated in and the functionality will degrades over time. Our micrometrical scale solutions is perfectly controllable and lasts forever.


The functionality is through and through in the material. So it is not just on the surface and it cannot wear off.


Our technology does not migrate. So it does not loose its effectiveness and the technology does not wear out. It lasts forever.


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


We are using newly discovered methods in combination with one of the most important natural trace elements. We do not use chemicals, pesticides, biocides, silver or other harmful substances.


Temperature conditions do not influence the functionality of the technology.


The shape of a product does not influence the functionality of the technology.


Light has no influence on the performance of the technology.


We only use authorised (food grade) substances in our materials.


99,9% and higher EFFECTIVENESS ACCORDING TO ISO 22196 AND JIS Z 2801

ISO 22196 and JIS Z 2801 are international standard that specifies a method of evaluating the antibacterial activity of antibacterial-treated plastics and other non-porous surfaces of products. Following these standards our materials show an antibacterial effectiveness level of 99,9% and higher.

The bacteria’s used for the tests are: Staphylococcus Aureus (gram+) a common bacteria that causes serious food poisoning, and the Escherichia coli (E.Coli)(gram-) which is a common cause of skin infections, respiratory disease and food poisoning.

antimicrobial polymers


Flat plastic parts of 50x50x10mm are prepared of treated and untreated material. A specified doses of the bacteria are placed on both the treated and untreated plastic parts and both are placed in incubation for 24 hours at 35°C and a relative humidity of no less than 90% (ideal conditions for bacteria to grow). After the incubation period the specimens are studied and the viable bacteria count is determined. A prescribed equation records the results showing the difference in viable bacteria on the treated and untreated plastic parts.

We have not just limited our tests to the above two bacteria’s. An equal effectiveness level has been observed for other bacteria, such as Methicillin-resistant Staphylococcus aureus (MRSA), Acinetobacter Baumannii, Pseudomonas aeruginosa, Enterobacter cloacae, Clostridium difficile and Candida albicans.

By ISO 22196 the Parx Plastics technology proves indisputably to have a remarkable effectiveness level of 99,9% and higher for its antibacterial effect, on wide range of bacteria, without degrading in time.

Cytotoxicity is the ability of an (chemical) agent to cause physical or biological damage to human cells. We have identified that materials or products produced with the aid of Saniconcentrates are not cytotoxic and they are fully safe in contact with humans and nature. To scientifically proof this we executed three types of tests: “Test of cell viability by staining with Trypan blue”, “Production of Nitrite in THP-1 cells” and “Sage of cytotoxicity by LDHdosage.” The Parx Plastics innovations prove to be not cytotoxic and therefore fully safe for human cells.


To confirm the stability of our plastics we have performed migration tests according to the “Regulation (EU) No. 10/2011 on plastic materials and articles intended to come into contact with food”. The tests are to verify both the durability of the material and specifically the compatibility of the material for applications that come in contact with foodstuff.

The above-mentioned EU regulation prescribes that plastic materials and articles shall not release specific materials in quantities exceeding 5 mg/kg food or food simulant. We verified our materials and we applied the above tests to confirm if there was a supply of material in ionic form exiting our material and if so, in what quantities. The plastic specimens were placed in contact with for example these food simulants:

  • Food simulant A: Ethanol 10%

  • Food simulant B: acetic acid 3% (w/v)

  • Food simulant C: 10% ethanol (v/v)

  • Food simulant D: oil or saliva adjusted or a mixture of synthetic triglycerides or sunflower oil

In particular, we want to highlight the tests performed with Simulant B (acetic acid), which represents the most aggressive method. The test was performed under specific conditions with a temperature of 70°C for 2 hours as described by the legislation referred to above. Of this solution 50ml was used to completely immerse the specimens. The solutions obtained after treatment, were subjected to elemental analysis by ICP-AES using a tool “Ultima2” of the company Horiba Jobin Yvon. The results turn out to be phenomenal. We see migration levels that are *below 0,001PPM and these are considered negligible as the results are under the instrument toleranceConcluding: we see no migration.

* The tolerance of our instruments is 0,001 PPM. This is the lowest possible value we can measure, values lower than this tolerance cannot be measured. The EU regulation describes a minimum tolerance of 0,01 PPM.
