Flea collar matrix
The plastic a flea collar is made of, named among its inert ingredients. It holds the actives and lets them out slowly.
Watched ingredients get highlighted on every product panel you open.
- Where it comes from
- Polymer plants.
- Why it's in the product
- The body of the collar.
- Safety and toxicity
- A collar is worn, not chewed, so the reason we flag synthetic toy materials, pieces chewed off and swallowed, does not apply.
General reference, not veterinary advice. Dose, breed, and existing conditions change the answer, so talk to your vet before changing what your pet eats. Think we got this wrong? Tell us and we log it publicly.
Not in anything we've scored yet
No product in our database lists this on its panel. That says more about how much we have scored so far than about how common the ingredient is.
