How to Make Scented Slime

Scented slime takes clear glue, a saline activator, and a skin-safe fragrance oil. Here is the nine-step method we use, how much fragrance to add, why a skin-safe oil holds up where perfume does not, and how to handle it safely.

Scented slime is a stretchy craft putty you make from clear school glue and a saline activator, with a fragrance oil stirred in so it smells as good as it feels. The scent is what turns a basic slime into a party favor or a gift, and the choice that matters most is the oil. A skin-safe fragrance oil blends into the glue and holds its scent through repeated handling. We carry over 275 fragrance oils, and every product page lists the skin and lotion compatibility you need to pick one that is safe to touch.

This guide walks the full method: what to gather, the nine steps from glue to finished slime, how much fragrance to add, why a skin-safe oil outlasts perfume, and how to keep the activator safe for the kids who will be squishing it.

What You'll Need

Gather everything before you start, since the activator stage moves quickly once the slime begins to form. The measuring tools do not have to be exact; slime is forgiving.

Supplies

Clear Crafting Glue

One cup of clear PVA school glue. Clear glue gives the brightest color and shows off glitter; white glue works too for an opaque, pastel slime.

Skin-Safe Fragrance Oil

The scent. Use an oil rated for skin contact, since slime is handled directly. Check the product page for skin and lotion compatibility before you buy, and browse the range in our fragrance oils collection.

Baking Soda

A small amount firms the slime and helps the activator work.

Food Coloring

A few drops of water-based food coloring or any water-based colorant.

Glitter

Optional, for sparkle. Cosmetic or craft glitter both work.

Saline Contact Solution

The activator. It needs to contain boric acid and sodium borate to set the slime; check the label.

Mixing Bowl, Measuring Cup, and Spoons

For combining and portioning.

Rubber Spatula

For stirring and scraping the bowl clean.

Clamshell Mold

Optional, for packaging finished slime as favors or gifts.

Cover your workspace with butcher paper or newspaper first. Glue and food coloring drip, and a covered surface makes cleanup quick.

How to Make Scented Slime

The order matters: scent and color go into the glue first, and the activator goes in last and slowly. Add the saline a little at a time, because too much at once turns the slime stiff and rubbery.

Nine Steps from Glue to Slime

  1. 1

    Measure the glue

    Pour one cup of clear crafting glue into the mixing bowl. Scrape any glue clinging to the measuring cup with the rubber spatula so your measurement stays accurate.

    Measure the fragrance oil

    Measure about half a teaspoon of skin-safe fragrance oil and pour it slowly into the glue.

    Stir in the fragrance

    Stir the fragrance oil into the glue with the rubber spatula until it is fully blended and no streaks remain.

    Add the baking soda

    Measure about an eighth teaspoon of baking soda and add it to the glue.

    Add the food coloring

    Add a few drops of water-based food coloring until you reach the shade you want. Start light; you can always add more.

    Stir in the color and soda

    Stir until the baking soda and food coloring are fully dispersed. Baking soda tends to clump, so work out every lump before moving on.

    Add glitter

    Sprinkle in glitter to your preference and stir it through with the spatula. This step is optional.

    Add the saline activator

    Squeeze in a little saline contact solution and stir. Keep adding small amounts and stirring until the slime starts to ball up and pull away from the bowl. Once it does, coat your hands in saline and knead it by hand.

    Knead until it stops sticking

    Keep kneading and adding a little saline at a time until you can pick the slime up without it sticking to your skin. When it lifts clean, the slime is ready.

Make It Your Own

Once the slime lifts clean, it is finished and ready to play with or package. Pressing a batch into clamshell molds turns it into a party favor or a gift, and a printed label personalizes it for a birthday or a class party. Slime keeps best sealed in a clamshell or an airtight container between uses, which slows the scent from fading and stops the slime from drying out.

Frequently Asked Questions

How do you make scented slime?

Stir about half a teaspoon of skin-safe fragrance oil into one cup of clear school glue, add roughly an eighth teaspoon of baking soda, then a few drops of food coloring and glitter if you want it. Add saline contact-lens solution a little at a time, stirring, until the mixture pulls away from the bowl and stops sticking to your hands. It is ready when you can pick it up clean.

Can you use perfume to scent slime?

Perfume works poorly. Most perfume is mostly alcohol and water, which thins the slime and breaks down the stretch, and the scent fades fast as the alcohol evaporates. A skin-safe fragrance oil blends into the glue, holds its scent through repeated handling, and lets you control how much you add. Use the fragrance oil and skip the perfume.

How much fragrance oil do you put in slime?

About half a teaspoon of skin-safe fragrance oil per cup of glue is a good starting point. Add it to the glue before the activator and stir it in fully. You can adjust up or down to your preference on your next batch, but keep the fragrance at a skin-safe level, since slime is handled directly.

Is scented slime safe to handle?

Use a fragrance oil rated for skin contact, supervise children, and have everyone wash their hands after playing. The saline activator contains boric acid, which can irritate skin and eyes with prolonged contact, so do not leave slime on the skin for long, keep it out of eyes and mouths, and stop if any redness appears.

How do you make slime smell good for longer?

Use a skin-safe fragrance oil rather than perfume, mix it into the glue thoroughly so the scent is distributed evenly, and store the finished slime in a sealed clamshell or airtight container between uses. Sealed storage slows the scent from fading and keeps the slime from drying out.
