Biocidal Products (PT1–PT22): Product Types, Use Areas and Correct Compliance Approach

Biocidal products are products used in critical areas such as disinfection, protection and pest control. There are three essential elements for a successful biocidal license: correct product type (PT) selection, clear use definition and consistent documentation. PT1–PT22 classification requires that formula, use area and label claim are consistent, measurable and auditable with each other. When the correct framework is established, the process proceeds predictably, efficiently and robustly in the face of audits.

Product Types (PT1–PT22) and Main Groups

A. Disinfectants (PT1–PT5)

PT1 – Human hygiene: Products for hand and skin hygiene.

PT2 – Surface/area & algicide: Disinfection/alg control in environment, surfaces and water systems.

PT3 – Veterinary hygiene: Animal production and equipment hygiene.

PT4 – Food and feed area: Food contact surfaces and production area.

PT5 – Drinking water: Disinfection in drinking water.

B. Preservatives (PT6–PT13)

PT6 – Product preservatives (preventing deterioration during storage)

PT7 – Film preservatives (coating/film layers)

PT8 – Wood preservatives

PT9 – Fibre/leather/rubber/polymer preservatives

PT10 – Construction material preservatives

PT11 – Industrial water systems

PT12 – Slimicides

PT13 – Metalworking fluid preservatives

C. Pest Control (PT14–PT19)

PT14 – Rodenticides

PT15 – Bird control products

PT16 – Control of other invertebrates

PT17 – Fish control (special cases)

PT18 – Insecticide/acaricide etc.

PT19 – Repellents/attractants

D. Other Biocides (PT20–PT22)

PT20 – Control of other vertebrates

PT21 – Antifouling products

PT22 – Embalming & anatomical preparation

Important: Product type (PT) should be evaluated together with formula, use scenario and label claim. Contradiction in this trio prolongs the process.

Compliance Approach: Simple, Consistent, Defensible

PT Verification

Fix the correct PT according to the product's actual use; wrong PT creates unnecessary test/documentation and time loss.

Claim–Data Consistency

Expressions such as "antibacterial/antiviral/algicide" must be proven in the dossier.

Document Integrity

Label, SDS (Safety Data Sheet) and technical content should convey the same message.

Quality Infrastructure

Keep purity/specification documents ready for active substance and co-formulants.

Planned Progress

Create role and time plan for internal teams; manage revisions in a controlled manner.

Use Scenario and Claim Examples (Summary)

• Disinfectants (PT1–PT5): Human hygiene, surface/equipment, food area and drinking water applications.
• Preservatives (PT6–PT13): Protection of product/surface/flow against microbial deterioration.
• Pest control (PT14–PT19): Rodent, bird, invertebrate and insect control; repellent/attractant solutions.
• Other (PT20–PT22): Niche and technical applications (e.g. antifouling).

Common Mistakes

1. Wrong PT selection: Test and content plan becomes void, schedule extends.
2. Claim–data gap: Failure to prove label claims increases rejection/deficiency risk.
3. Inconsistent documentation: Label, SDS and technical content convey different messages.
4. Unpreparedness: Delay in active substance and quality proofs extends market entry time.

Simple Roadmap

1. PT verification (PT1–PT22)
2. Clarification of claim and use text (measurable/auditable)
3. Evidence structure (efficacy approach, quality, safety – planning without going into technical detail)
4. Document integrity (Label + SDS + technical content compliance)
5. Schedule and responsibility (internal coordination and stakeholder management)

Conclusion

Biocidal license success begins with correct product type (PT), consistent claim–use and integrated documentation. This framework accelerates in audits and market access, reduces risks.
