Irritant Spray, Pepper Spray, Animal Repellent: What's What and What's Allowed?

The Terminology Maze

In German law and retail, several terms are used that mean similar but not identical things:

Pfefferspray (pepper spray): General term for OC-based sprays
Reizstoffspray (irritant spray): Broader term covering CS gas and OC sprays
Tierabwehrspray (animal deterrent spray): Legal classification allowing sale without permit restrictions
CS gas: Tear gas compound (2-chlorobenzalmalononitrile)
OC: Oleoresin capsicum — the active component in pepper sprays

Understanding which category a product falls into determines what you can legally buy and carry.

OC vs. CS: The Chemistry

OC (Oleoresin Capsicum)

Derived from chilli peppers. Causes intense burning pain in eyes and skin, temporary blindness (20-45 minutes), and respiratory distress.

Advantages: Works on people regardless of mental state (including those under drug influence), animals, and is considered more physiologically reliable than CS.

Disadvantages: Slightly slower onset than CS in some formulations.

CS (2-Chlorobenzalmalononitrile)

Synthetic tear gas compound. Causes tearing, eye pain, respiratory irritation, skin burning.

Advantages: Fast onset.

Disadvantages: Effectiveness on highly agitated individuals (adrenaline, drugs) is less reliable than OC. Considered by some to be less effective for civilian self-defense than OC.

Recommendation for most users: OC formulation.

The "Tierabwehrspray" Legal Classification

Under German law (Waffengesetz), sprays classified as "Tierabwehrspray" (animal deterrent) can be purchased and carried by adults (18+) without a weapons permit.

Key point: This is a legal classification based on labeling and packaging, not just the chemical content. The same OC compound can be in a "Tierabwehrspray" (legal without permit) or a "Selbstverteidigungsspray gegen Menschen" (may require permit in certain formulations).

What to buy: Look for the "Tierabwehrspray" label on the packaging. This confirms legal carry without Waffenschein for adults.

What's NOT Allowed Without Permits

Sprays explicitly labeled for use against humans (without the Tierabwehrspray classification) — legal ambiguity, avoid
CN gas (chloroacetophenone, older tear gas compound) — prohibited
Mace brand original formulation (CN-based) — not the OC-based Mace sold today

Concentration and Size

Concentration: OC sprays are often rated in SHU (Scoville Heat Units) or OC percentage. For self-defense, 1-3% OC concentration in a stream spray is typical. Higher concentration is not necessarily more effective.

Spray pattern:

Stream: Long range (3-5m), accurate, less wind-sensitive. Preferred for outdoor use.
Fog/mist: Faster to deploy, more area coverage, wind-sensitive. Better indoors.
Gel: Good range, sticks to target (reduces secondary contamination), less wind-sensitive.

Size: 40-50ml canisters are common and practical. Enough for multiple deployments.
