Why Cold Process Soap?

Cleansing soaps as we know them today date back in history thousands of years, to when the ancient Babylonians combined animal and vegetable fats with ash for cleansing purposes.

Although modern-day soaps are made with advanced ingredients, they essentially take their core form from these historical versions, old-fashion soap, gently cleaning and nourishing the skin.

Making cold process soap has been passed down through the ages to create the highest-quality soaps for ultimate cleansing and moisturization through the soap production process.

What Is The Cold Process Method To Make Soaps?

In cold processing soap making, the oil or fats are mixed in sodium hydroxyl lye in a process called saponify. Alternatively, colors, fragrances, and other additives are also possible in a saponification step.

The name 'cold process soap making' might make you believe that the finished product won't involve heat, but that's not actually true. The heat produced in oils in lye and hydroxide is dependent upon the quantity of the base ingredients.

This heat-generated part or gel phase is commonly encountered in soap making processes. Aside from the gel phase, external heat is not required to neutralize the lye.


Old Fashioned Cold Process Soap Making

The traditional way of soap making is often considered a "cold process" because no external heat is used in the saponification phase.

Cold process soap makers can precisely control the saponification process by avoiding heat and only mixing to a stable emulsion (trace), which allows for intricate soap designs such as swirls and other patterns.

The most common technique of artisan soap creation is cold soap making, which is also the preferred way to make handcrafted soaps since it offers a huge and limitless range of design options.

This technique is renowned as one of the best ways to preserve natural ingredients added to the soap, such as essential oils, and create an extra-soft finish with no rough edges.

• Intensifies the fragrance

Many soaps are fragranced with natural extracts; cold processed soap is cured for between four and six weeks, intensifying the scent such as lavender, jasmine, vanilla, and chocolate, to name a few

• Preserves natural ingredients like liquid oils

Olive oil, shea butter, hemp oil, and coconut oil are all luxuriant natural products that are fully preserved by the cold process.

• Feels like a lotion
