The Art of Making Floating Soaps: Techniques, Processes, and Uses

Creating floating soaps is a fascinating art that combines traditional soapmaking techniques with a unique twist. This article will guide you through the process of making soap that floats, explore the history and potential of this technique, and share insights into soap lathering and quality.

History and Commercial Potential of Floating Soaps

Back in the 1980s, a method was developed to make soaps that float in water. While the initial commercial potential was deemed minimal, this technique offers new opportunities for those interested in marketing these unique soaps. If you are intrigued by the idea of developing this method for marketing purposes, I would be delighted to assist you. However, a non-disclosure agreement (NDA) is a prerequisite for any collaboration.

This method has been adapted for personal use at home, making soaps for bath time adventures. Various molds, like fish, crabs, and stars, were used to create fun and engaging soaps for children.

Salting-out Soap Process: Floating Soap Making

One of the essential techniques for making floating soaps is the salting-out soap process. This method involves boiling soap with a salt solution, which results in a cleaner soap floating on top of a liquid containing most of the salt impurities and excess lye. The process is divided into several phases that collectively ensure a high-quality and effective floating soap.

Salting-out Phase

To begin, heat the soap with a salt solution. The resulting mixture separates, with the cleaner soap floating on top. This phase is crucial as it removes unwanted impurities and improves the overall quality of the soap.

Fitting Phase

In the next phase, referred to as the Fitting or Change or Killing Phase, the soap is dissolved by heating it with water and added lye. This step allows for the saponification of the remaining fat or oil that did not react during the initial stages. The process ensures that all the soap is fully reacted and free from unprocessed fats.

Cooling and Solidification

After a period of heating, the mixture is cooled and allowed to dry. At this point, the solid soap is ready for the next phase of the process.

Closing Phase

The final phase involves dissolving the solid soap in water only. This process, known as Closing Soap, results in a solution that is then set for a few days. During this period, the neat or pure soap settles to the bottom, while the rest of the impurities rise to the top, creating a clear and pure soap.

Quality and Lathering of Soaps

The quality of your soap bar is determined by the oils you choose. For instance, castor oil at 5% content provides a stable lather, while coconut oil produces big, fluffy bubbles. Sugar can also be used to enhance lathering and bubbles, and can be replaced with honey or even beer or milk as alternatives to water. Lard gives a creamy lather, while olive oil, used in excess, will hinder lather formation.

The key is to find the right combination and balance of oils. Avoid having too many free oils, and maintain a superfat level of around 5% to ensure the soap bar is gentle and effective on the skin.

Personal Cleansing Preferences

While the quality and effectiveness of the soap are crucial, the method you use to cleanse your skin is a matter of personal preference. Whether you prefer hand cleansing, body cleansing, or any other method, it's all about finding the technique that works best for you.

We thought we would share a few examples of traditional cleansing methods to give you an idea of the different techniques available. Whether you prefer lathering bars, cream-based cleansers, or liquid soaps, the choice is yours.
