A tool designed to determine the correct amount of fragrance oils, specifically essential oils, to incorporate into handmade soap recipes ensures a balanced and safe final product. For example, a user might input the type of soap base, its weight, and the desired fragrance strength, and the tool would calculate the precise volume or weight of essential oil required.
Accurate fragrance blending is critical for both the quality and safety of handmade soaps. Too much essential oil can cause skin irritation or sensitization, while too little may result in a barely perceptible aroma. Historically, soap makers relied on experience and rough estimations. The development of online calculators and dedicated software provides a more precise and reliable method, particularly for those new to soap making or working with unfamiliar essential oils.
