Why is My Soap Not Hardening?

One of the most asked questions we came across so far when it comes to soap making is Why is my soap not hardening? We all know hardness is a key characteristic of handmade soap. This factor ensures the durability and lather of a soap. As it is a challenge for both professionals and beginners, we are here to help you with a detailed blog on it.

Why is My Soap Not Hardening?

What is Soap Hardness?

As the name suggests, soap hardness is the physical firmness of the soap bar. It is basically influenced by the presence of fatty acid composition in the soap and also depends on the type of lye used. If your soap is hard, then it has better durability and is resistant to dissolving quickly in the water while offering longevity.

Reasons: Why is My Soap Not Hardening?

Like most of you have asked, why is my soap not hardening? Here are some of the common reasons behind it.

Why is My Soap Not Hardening?

1. Incorrect Lye-to-Oil Ratio

When you are making a DIY soap, if you choose the incorrect oil-to-water ratio, then it can result in a soft soap because of the presence of extreme superfat.

2. Too Much Soft Oil (e.g., Olive, Castor)

If your recipe has too much soft oil, like olive oil and castor oil, then your soap may take longer to harden, but if you maintain the water content, it gets easier.

3. Not Enough Curing Time

We have to understand that these DIY soaps usually need 4-6 weeks to cure completely. So, you also need curing time for your homemade soap recipes.

4. High Humidity During Curing

Another reason is the temperature change; high humidity does not give you an ideal soaping temperature, which can make your soaps softer.

5. Water Content Too High

Using too much water while making soap can also make the soap soft. Although it will eventually harden, it will take a longer duration of time.

6. Soap Not Fully Saponified

Another reason why your soap may not be hardened is that the soap might not have been fully saponified. This means you have to correct your ingredient measurements.

7. Added Ingredients Retaining Moisture

There are some additives that you may have used while making the soap, like honey, aloe vera, or milk, which might keep it soft for a longer period of time.

8. Not Enough Hard Oils or Waxes

When it comes to making soap, you can never go wrong with hard oils or waxes, so the wrong proportion of these ingredients can also be the reason why your soap is not hardening.

9. Glycerin Overload

The wrong glycerin ratio or an overload of this ingredient, especially during the melt and pour phase, can result in a soft soap.

10. Mistake in the Recipe or Measuring

Last but not least, the common mistake can be a little issue in your measurements or the recipe. So, pay attention when you follow the soap-making recipe.
