Why does my slime smell like plastic or have a sour smell?

Looking at most recipes, PVA glue will be used to make slime. If the raw material of the PVA glue used, that is–PVA, is not pure and contains impurities, then the slime you make will have an odor. Although it doesn’t smell good, it’s usually not nauseating.

What are these bad smells?

PVA smells unpleasant mainly because the production process is not pure and contains residual sodium hydroxide, sodium acetate, and other impurities.

Why does the slime I buy have a scent but smell disgusting?

There are roughly two reasons. Usually, the scent we add to slime is artificial. Some scents exist naturally, but the extraction cost is too high, so they are artificially synthesized.

Reason 1: You are allergic to a specific scented chemical molecule.

Reason 2: The slime contains CH₂O(formaldehyde), Kathon, and other preservatives. No one can tolerate these smells.

Slime is primarily composed of water and is a natural breeding ground for germs. To extend the shelf life of slime and prevent slime from getting moldy, bactericidal substances need to be added to kill germs.

The manufacturer adds fragrance to cover up the smell of formaldehyde or Kathon, but this does not eliminate the formaldehyde or Kathon. They still exist. (There may be other preservatives that are not allowed in toys)

How to add scent to slime?

  1. Choose edible flavors as scents.
  2. Check the instructions and dilute it by slime weight.
  3. Add the diluted scents after your slime is complete and ready for normal play. Do not add scents during the production process.
