What Makes Cold Process Handmade Soap Different?

There are many cold process handmade soaps on the market—but not all soaps are made the same.

It’s a common misconception that all handmade soaps are identical. At markets and events, I often hear people say, “I bought one like this last week,” when in fact every maker, recipe, and ingredient choice is completely different.

So what actually makes cold process soap different?

Cold Process vs Melt and Pour Soap

Cold process soap is made from scratch using oils, water, and sodium hydroxide (caustic soda). Through a chemical reaction called saponification, these ingredients transform into soap.

Melt and pour soap, on the other hand, is a pre-made base that is melted down and customised with colours, fragrances, or additives.

While both are considered handmade, cold process soap allows full control over ingredients, formulation, and final quality.

Why We Use Palm Oil

Palm oil is one of the most debated ingredients in soap making.

We use sustainably sourced palm oil because it helps create a hard, long-lasting bar with a creamy lather and balanced skin feel.

The palm oil we use is certified under the Roundtable on Sustainable Palm Oil (RSPO), ensuring responsible sourcing practices.

According to the World Wildlife Fund, palm oil is a highly efficient crop, producing more oil per land area than most alternatives.

Butters in Soap Making

Ingredients like shea butter, mango butter, and cocoa butter are often used to enhance soap recipes.

While they can add luxury and skin feel, their functional impact in soap is often subtle. Due to their cost, we reserve these ingredients for leave-on skincare products.

Essential Oils and Fragrance

Fragrance is a key part of soap formulation and must be carefully balanced.

We use high-quality essential oils at the upper end of recommended usage rates to ensure a lasting scent.

For example, rose geranium essential oil is one of our most popular scents, but true, high-quality oil can vary significantly in price and purity.

This variation directly affects the final soap cost and quality.

Natural Colours vs Synthetic Colours

The colour of a soap often tells you a lot about its ingredients.

We use only natural colourants such as clays and botanical extracts.

Some soaps use synthetic colourants or mica-based pigments, which can create brighter colours but may not align with a fully natural formulation philosophy.

Choosing the Right Oils

The oils used in soap making dramatically affect performance, feel, and longevity.

For example:

• Olive oil creates a gentle, conditioning bar but low lather
• Coconut oil creates rich bubbles but must be balanced to avoid dryness
• Avocado, hemp, and macadamia oils add luxury and skin conditioning properties

Each oil plays a role in creating a balanced, well-performing soap recipe.

Final Thoughts

Cold process soap is not just “soap”—it’s a carefully balanced recipe where every ingredient matters.

Just like baking, the final result depends entirely on the quality and balance of the ingredients used.

When choosing a handmade soap, it’s worth remembering that no two bars are ever truly the same.
