Soap formulation kit: learn how to create your own soap recipes

Have you always dreamed of making your own soap, but feel overwhelmed by the variety of oils available and the technical concepts behind the saponification process? Learning to craft handmade soap is one of the best things I ever decided to do. With the right foundation, you can get creative and produce a wide range of practical, cost-effective soaps. However, when you want to move beyond the recipes found in books and start formulating your own soaps, many questions naturally arise.

Which oil should you choose? Why does each oil require a different amount of caustic soda? How do you accurately calculate the proportions for every ingredient? To help you answer these questions, I’ve created my soap formulation kit. A collection of educational resources designed to guide you through the world of soap formulation and help you grasp the essentials needed to develop your own unique recipes.

What is the soap formulation kit?

The soap formulation kit is a learning tool designed to make the formulation process more accessible to beginners. Instead of having to search for information across numerous websites, compare various sources, and struggle to figure out complex calculations on your own, you are provided with several complementary resources that allow you to progress at your own pace.

The kit includes:

• A concise guide covering the fundamentals of soap making, along with supplementary materials.

• A list of 30 oils useful for soap formulation.

• A Google Sheets-based formulation calculator to assist you with your calculations.

Whether you are a complete beginner or already experienced in making soap, these tools will help you gain a better understanding of ingredients and take your first steps toward formulating your own recipes independently.

A guide to understanding soap making

Before creating your own recipes, it is essential to understand how soap making works. The guide included in the kit will help you discover the fundamental principles of saponification and the role of the various ingredients. You will gain a better understanding of the production stages, the importance of proportions, and the necessity of performing precise calculations before preparing a recipe.

The goal is not simply to follow instructions without understanding them, but rather to begin grasping the logic behind each formulation. This understanding will gradually enable you to make more informed choices and approach your future experiments in a more methodical way.

A list of 30 oils useful for formulating your soaps

Choosing oils is one of the most engaging stages in formulating handmade soap. Each oil has a unique fatty acid composition, which influences the characteristics of the finished soap. Some contribute to its hardness, while others help create lather or affect its cleansing properties. However, with so many vegetable oils available, it can be difficult to know where to begin.

That is why this kit includes a list of 30 oils useful for soapmaking. This list serves as a practical starting point for discovering oils commonly used in soap formulation and gaining a better understanding of their specific qualities. It will allow you to explore various raw materials, compare their properties, and consider potential combinations to create your own recipes.

As you experiment, you will also be able to observe how adjusting the proportions of an oil or swapping one oil for another, affects the characteristics of your soap. The goal is not to memorize every property of every oil, but rather to learn how to use them thoughtfully to develop well-balanced formulations.

A soap calculator on Google Sheets

The amount of caustic soda required to make soap is a crucial factor. Every oil has its own unique saponification value, which means that different oils do not necessarily require the same amount of sodium hydroxide (NaOH) to undergo saponification. For this reason, you should never replace one oil with another in a recipe without recalculating the amount of caustic soda needed.

To assist you with this step, the kit includes a soap formulation calculator in Google Sheets. This tool helps you work with the oils you have selected and calculate the corresponding amount of caustic soda, based on the parameters set within the spreadsheet. Instead of performing every calculation by hand, you have a practical resource for exploring different oil combinations and understanding how the required quantities change when you modify your recipe.

The calculator also serves an educational purpose: it allows you to put the concepts covered in the guide into practice and gain a better understanding of the mechanics of formulation. However, it does not replace the need to understand the calculations yourself or to carry out essential checks before you begin production. It remains vital to verify the parameters used, the saponification values, the purity of the caustic soda, and your desired superfatting percentage.

Why learn to formulate your own soaps?

Following a recipe is an excellent way to discover the craft of soapmaking. However, learning to formulate your own soaps opens up new possibilities.

Gain creative freedom

You can experiment with different combinations of oils, adjust proportions, and explore the specific characteristics you want to achieve in your soap.

Better understand your ingredients

Instead of choosing an oil simply because it appears in a recipe, you learn to consider its properties and the role it plays within the formulation.

Understand lye calculations

Mastering these calculations allows you to understand why every recipe requires a specific amount of lye tailored to its composition and why any change must be verified.

Gradually develop your independence

With practice and a solid knowledge base, you will be able to build, analyze, and adjust your own formulations, rather than relying solely on recipes created by other soapmakers.

Whether you make soap for your own enjoyment, as gifts for loved ones, or as part of a professional soapmaking venture, understanding formulation provides a valuable foundation for your continued progress.
