Why soap melts and how to prevent it

Why Does Bar Soap Melt? Causes and Solutions

Bar soap is a sustainable and eco-friendly alternative to liquid soap. However, many people experience the problem of their soap becoming soft, melting, or leaving a slimy residue in the soap dish. But why does this happen? And what can you do about it? In this article, you’ll learn the most common causes and the best solutions to keep your soap dry and long-lasting.

The Most Common Reasons Why Soap Melts

1. Too Much Water Exposure

Soap is made from fats, oils, and lye, all of which are water-soluble. If the soap sits in a puddle of water or is stored directly under the shower stream, it will start to dissolve. This problem is especially common with soap dishes that don’t have proper drainage, as they allow water to collect and soften the soap.

2. High Humidity

In poorly ventilated bathrooms, high humidity can cause moisture to accumulate in the soap. This leads to the soap swelling and losing its firm consistency. This issue is particularly noticeable during warm months or after hot showers.

3. Soft Soap Formulations

Not all soaps are the same. Natural soaps, which are often highly superfatted, contain more glycerin and moisture. While these soaps are very nourishing, they also tend to soften more quickly. Cold-processed soaps with a high content of unsaponified oils are also more prone to absorbing moisture.

4. Heat and Direct Sunlight

High temperatures can cause soap to soften or melt more quickly. If it’s placed on a windowsill or near a sunny spot in the bathroom, it will become softer. This is especially true for soaps with a high percentage of plant-based oils, which can liquefy under heat.

How to Prevent Soap from Melting

• Use a magnetic soap holder: Our magnetic soap holder keeps your soap suspended in the air, allowing it to dry completely from all sides. This prevents soap residue buildup on surfaces and extends the lifespan of your soap.
• Store your soap in our travel soap case: This innovative soap case features a removable suction cup holder inside, ensuring that your soap stays dry and doesn’t come into contact with water or the case walls. This keeps it ready to use, no matter where you are.
• Reuse soap scraps: If your soap has become soft, collect the remaining pieces in a soap bag and use them for showering or hand washing.

Conclusion: Proper Storage Makes a Difference

Bar soap is a great, sustainable alternative to liquid soap, especially since it doesn’t require a soap dispenser. The most common reasons for soap melting include excessive water exposure, high humidity, heat, or a soft formulation. With simple measures like a magnetic soap holder, a travel soap case, and proper drying, you can prevent your soap from melting and enjoy it for longer.
