Cold Process vs Hot Process vs Melt-and-Pour: Which Soap is Best for You?

🧼 Introduction: Cold Process Soap vs Hot Process Soap

When it comes to handmade soaps, there are three main methods: cold process, hot process, and melt-and-pour. Each produces unique soaps with different textures, looks, and skincare benefits.

In this article, we will explore the differences between cold process soap vs hot process soap to help you make an informed choice.

At Milele Soaps, we specialize in cold process soaps because they retain the maximum goodness of natural oils. Let’s compare all three methods so you can choose the best one for your skin.

🌿 What is Cold Process Soap?

Cold process soap is made by mixing natural oils with lye and letting it cure for 4–6 weeks.

Pros:

• Retains glycerin (natural moisturizer)
• Smooth, creamy lather
• Long-lasting bar
• Fully customizable with natural ingredients

Cons:

• Requires curing time (not instant use)

🔥 What is Hot Process Soap?

Hot process soap uses the same ingredients as cold process but is “cooked” with heat (usually in a slow cooker), speeding up saponification.

Pros:

• Ready to use in 1–2 weeks
• Rustic, textured look
• Good for adding herbal infusions after cooking

Cons:

• Less smooth finish
• Fragrance may not last as long

🍯 What is Melt-and-Pour Soap?

Melt-and-pour soap starts with a pre-made soap base that is melted, customized, and poured into molds.

Pros:

• Very easy for beginners
• No lye handling required
• Creative designs (layers, embeds, colors)

Cons:

• Not fully “from scratch”
• Usually contains synthetic ingredients
• Less moisturizing than cold process soaps

Cold process soaps are usually harder and last longer, especially after curing.
