Butters and waxes are commonly used in soap-making to add moisturizing properties and to harden the soap. They can also be used to add a creamy lather and to give the soap a more luxurious feel. Some popular butters used in soap making include shea butter, cocoa butter, and mango butter. Waxes such as beeswax and carnauba wax can also be used to add firmness to the soap. When using butters and waxes in soap making, it is important to use the proper amount in order to achieve the desired properties in the final product. It is also essential to use a high-quality, pure form of the butter or wax to ensure the best results.
