Can Slime be Scented

Typically, slime has no scent or odor. When the manufacturer does not add fragrance to it, you won’t smell anything.

Of course, we can add scent to slime to make it smell good. And, when you make homemade slime, you can try adding any scented product you like, such as perfume, essential oils or even body wash.

What Makes Slime Smell Good

The ingredient that makes slime smell good is fragrance. This general term includes a variety of chemicals.

Using different fragrances will make your slime toys smell unique. For example, some slime smell like sweet fruit or candy, while others make you feel like you’re in the garden.

Sometimes, manufacturers add fragrances that match the color of the toy. Like pink slime is usually strawberry scent, while brown slime may smell like coffee or chocolate.

How Much Scent to Add to Slime

Like food coloring, we only need to add a little fragrance (usually less than 1%) for the slime toys to smell good.

In fact, because of our sensitive sense of smell, too much fragrance can actually make slime smell bad. Therefore, when making homemade scented slime, we don’t add much fragrance.

Non Allergenic Fragrance

In actual production, our researchers spend effort to find a suitable formula. Because adding even a small amount of wrong fragrance to slime may cause allergies.

According to the European Toy Directive[1], we cannot add allergenic fragrances to toys. Chemical names and CAS numbers of these allergenic fragrances:

How to Make Scented Slime

At the factory, we make scented slime in the lab at our R&D center.

We will start mass production only after you have tested and approved the samples. Often, different customers’ slime recipes are unique and complex. On the contrary, the ingredients and operation of homemade scented slime are simpler.

Ingredients

  • PVA glue (preferably transparent)
  • Essential oils (can also be other scented ones)
  • liquid starch

Optional: glitter powder, food coloring, etc. (this can make slime more interesting)

Instructions

  • Step 1: Prepare a bowl and pour 300ml of glue.
  • Step 2: Drop in essential oil or other fragrances and stir evenly with a spoon. You can use a little more or less depending on your preference. Try not to mix multiple spices as the smell can get weird.
  • Step 3: Pour 150-300ml of liquid starch. We use liquid starch to make the slime flexiable and less stickness. You can add a little liquid starch first, and when you find it is too sticky, you can add it again.

Add glitter and food coloring in the second step, it can make your slime colorful and fun.

Tips and Warnings

The recipes online may teach you to make slime by mixing borax and glue. They are certainly effective, but please note that borax is not safe. If you’re going to make and play with kids, you’d better not use it.

The viscosity of slime is difficult to control when making it. The above recipe may not correct, you need to adjust it by adding liquid starch or glue during the mixing. When it’s too sticky, add liquid starch, and when it’s too hard, then add glue.

Since homemade scented slime does not have any added preservatives and antiseptic substances, it does not last long. Generally you should throw it away after 3-5 days, even if it doesn’t seem to have any problems. Because there are many bacteria growing in it where you can’t see it.

Making scented slime isn’t a simple job in the lab. We will test chemical ingredients to ensure the toys are actual non toxic and safe. Everything should meet the EU Toys Directive. At the same time, we also need to take into account the fun, durability and stability of slime.

How to Scent Slime Without Essential Oils

If you don’t like the smell of essential oils, you can try adding perfume or other scented lotions to your slime. But whatever you add, make sure it’s less.

Ingredients

  • baking soda powder
  • shampoo

Optional: glitter powder, food coloring

Instructions

  • Step 1: Prepare a bowl and pour 1 cup of baking soda.
  • Step 2: Squeeze 1 pump or 1 tablespoon of shampoo and mix it into the baking soda powder. If you like the slime fluffy, add more shampoo.

You can add coloring and glitter to make the slime more beautiful and interesting.

Tips and Warnings

Since the shampoo has scent, you don’t need to add additional fragrance. And the shampoo can foam, making the slime fluffy, like clouds. People make cloud slime at home using the above recipe.

If your shampoo is unscented, you can also switch to body wash or other scented lotion. Of course, you can also spray a little perfume.

Why Does My Slime Smell Bad

Sometimes, slime smells bad, and some reasons can cause it.

Reason 1: PVA Glue

When making slime at home, we use glue, which is the main ingredient. If the glue you use smells bad, the resulting will too.

Also, adding too much fragrance to slime can turn it into a bad smell.

Reason 2: Expired and Moldy

Usually, homemade slime has a short shelf life of only 4-5 days and is prone to spoilage. When slime goes bad, it may emit a bad smell. Especially those made with liquid starch or cornmeal, which can become a haven for bacteria and fungi.

Moldy slime will smell terrible and you’d better throw it away as soon as possible.

Reason 3: Fragrance Fades

The shelf life of a high-quality slime toy is usually 12-18 months, but the scent will fade with time. This is normal, and the scent is the result of the evaporation of fragrance. As the fragrance in the slime becomes less and less, the scent will fade or even disappear. And then you may find it smells bad.

Some substandard slime toys contain illegal ingredients which have an unpleasant odor. Unscrupulous merchants add additional fragrances to cover up these odors. When the scent fades, the bad smell will come out.

Reason 4: Allergy

You may be allergic to a certain fragrance ingredient. Sometimes, the body “alters” our sense of smell to protect us, making scented slime smell bad.

If you or your kids have sensitivities, it’s crucial to be aware of any ingredients that might cause allergies. Choosing slime toys that are fragrance-free or free of allergenic fragrances is the best option.

Reason 5: Dislike the Fragrance

Well, you won’t be surprised here, everyone has their own favorite scent. Occasionally, one may not prefer a certain taste.

How to Store Scented Slime

The key to storing scented slime is to seal it tightly and avoid contact with air.

The smell of scented slime comes from fragrance. The molecules of fragrance are active and will escape from the slime flying into the air. This is why slime has a scent.

However, as you continue to expose slime to air, the smell will evaporate and eventually fade and disappear. Therefore, sealing is the most important thing when storing this toy.

Putting the slime into the sealed bag or plastic box can keep the scent. When the kids aren’t playing with the slime, put it back in the packaging and seal it. It will emit a rich scent when the next play.

Conclusion

We can add different fragrances to the slime to give it scent. Although people like scented slime, according to European standards, slime toys cannot contain allergenic fragrances.
