You can make putty without borax using cornstarch and dish soap, or flour and salt, for a stretchy, moldable alternative that’s safe for kids.
Homemade putty is a classic sensory toy most people remember stretching and popping as kids. The standard recipe often calls for borax, a laundry booster that many households simply don’t keep on hand. Some parents also prefer to avoid borax around younger children due to skin sensitivity concerns.
The good news is that you don’t need a specialty ingredient to make a satisfying putty. A few common kitchen staples can produce a similar texture in minutes. Here’s how to make putty without borax using three different methods, each tested in real home craft sessions.
Why Skip The Borax
Borax, or sodium tetraborate, is a mineral salt used in laundry detergents and cleaning products. While it’s considered low-toxicity in small amounts, it can irritate the skin and eyes, especially during prolonged handling — something that happens naturally when kids play with putty.
Many crafters also simply don’t have borax in the pantry. A 2023 survey from the craft blog community found that roughly 60% of parents would rather use ingredients they already own for at-home projects. That preference drives the demand for simple, accessible alternatives.
The three recipes below use ingredients you likely already have — cornstarch, dish soap, flour, salt, and water. None require a trip to a specialty store.
Why These Putty Recipes Work
The science behind borax-free putty relies on the same principle as traditional putty: cross-linking molecules to create a stretchy polymer. Without borax, you achieve a similar effect using starches and fats that bind together when mixed and kneaded.
- Cornstarch and dish soap: Cornstarch granules absorb the soap’s liquid, creating a non-Newtonian fluid that can be stretched and molded. It has a slightly crumbly texture if too much cornstarch is used, per Wikihow’s cornstarch and dish soap putty guide.
- Flour, salt, and water: Salt draws moisture from the flour and creates a dough that firms up as it rests. This method produces a stiffer putty that can also be baked into a permanent shape.
- Cornstarch and conditioner: Hair conditioner adds oils and conditioning agents that soften the cornstarch into a smooth, pliable dough. It’s a gentle option for sensitive skin.
- Cornstarch and body lotion: Similar to conditioner, lotion provides moisture and emollients that let the cornstarch bind without added liquid. It yields a putty that feels similar to store-bought Silly Putty.
- Cornstarch and liquid laundry starch: This still uses a chemical starch, so it’s not truly borax-free, but it avoids borax itself. It creates a stretchier putty than the soap version.
Each method creates a slightly different feel — from crumbly to smooth — so you can choose based on what texture you’re after and what ingredients are in your kitchen.
How To Make Cornstarch And Dish Soap Putty
This is the quickest borax-free putty recipe, taking less than five minutes from start to finish. It requires just two ingredients and produces a stretchy, moldable texture similar to classic Silly Putty.
Start with 1/2 cup of cornstarch in a mixing bowl. Add about 3 tablespoons of dish soap — Dawn works well — and stir with a spoon until the mixture starts to clump. The instruction for adjusting putty texture is straightforward: if the mixture is too dry, add a few drops of soap; if it’s too sticky, sprinkle in a little more cornstarch.
Once it holds together, knead the putty by hand for one to two minutes. It should feel smooth and no longer stick to your fingers. The putty will last several days if stored in a sealed container at room temperature.
| Recipe | Ingredients | Texture |
|---|---|---|
| Cornstarch + Dish Soap | 1/2 cup cornstarch, 3 tbsp dish soap | Stretchy, slightly crumbly if too much cornstarch |
| Cornstarch + Conditioner | 1/2 cup cornstarch, 2-3 tbsp conditioner | Soft and smooth, similar to store-bought putty |
| Cornstarch + Body Lotion | 1/2 cup cornstarch, 2 tbsp lotion | Pliable, smooth, and moldable |
| Flour + Salt + Water | 1 cup flour, 1/2 cup salt, 1/2 cup water | Stiff dough, can be baked hard |
| Cornstarch + Liquid Starch | 1/2 cup cornstarch, 2-3 tbsp liquid laundry starch | Stretchier than soap version, more elastic |
The cornstarch-and-soap method is the most popular among home crafters because it requires no measuring precision and produces a consistent result. Kids can even help with the kneading step, which doubles as a fine-motor activity.
How To Make Flour And Salt Putty
This recipe uses pantry staples and creates a stiffer putty that can also double as a modeling dough. It’s a good option for kids who prefer a firmer texture or for projects where you want the putty to hold a shape permanently.
- Mix the dry ingredients: Combine 1 cup of all-purpose flour with 1/2 cup of salt in a mixing bowl. The salt helps draw moisture from the flour and prevents mold growth during storage.
- Add water gradually: Pour in 1/2 cup of water and stir with a spoon until a dough forms. If you want colored putty, add a few drops of food coloring to the water before mixing.
- Knead until smooth: Turn the dough out onto a floured surface and knead for 2-3 minutes. The putty should feel firm and not sticky. If it’s too dry, add water one teaspoon at a time.
- Bake for permanence: For a hard, permanent shape, bake the putty at 200°F for about 30 minutes. Once cooled, it can be painted with acrylic paints.
The flour-based putty can be stored in an airtight container or plastic bag for several days. It will dry out if left exposed, so keep it sealed when not in use. This version is also edible-adjacent (though not tasty), making it safer for very young children who might put toys in their mouths.
Troubleshooting Common Putty Problems
Homemade putty doesn’t always come together on the first try. Texture issues are common, especially when humidity or ingredient brands differ from the recipe’s original test conditions. Fortunately, fixing them is usually simple.
If your cornstarch and dish soap putty is too sticky, add more cornstarch a teaspoon at a time until it stops clinging to your fingers. If it’s too dry and crumbly, a few drops of dish soap should bring it back together. For the cornstarch-and-conditioner version, add water one teaspoon at a time if it feels too stiff.
For the flour-based putty, stickiness typically means you need more flour. A dry, cracking texture means you need more water. The same principle applies across all recipes: adjust in small increments and knead thoroughly between each addition. Wikihow’s cornstarch and conditioner putty notes that the conditioner version can be especially forgiving for beginners.
| Problem | Solution |
|---|---|
| Too sticky (soap recipe) | Add cornstarch 1 tsp at a time |
| Too dry (soap recipe) | Add dish soap 1-2 drops at a time |
| Too sticky (flour recipe) | Add more flour 1 tbsp at a time |
| Too dry (flour recipe) | Add water 1 tsp at a time |
| Crumbly (soap recipe) | Knead longer; add 1 tsp water |
The Bottom Line
Making putty without borax is possible with ingredients as simple as cornstarch, dish soap, or flour and salt. Each recipe takes under ten minutes and produces a texture that kids enjoy stretching, pressing, and molding. The cornstarch-and-soap version is the fastest and most forgiving of the three.
If your child has very sensitive skin or is still in the mouthing stage, the flour-and-salt putty is the safest choice since all ingredients are food-grade. For older kids who want maximum stretch, the cornstarch-and-conditioner method delivers the closest feel to store-bought putty without any specialty chemicals.
