What is the difference between SUMU-SU soap and commercial soap?
Commercial soap usually contains synthetic detergents and chemicals that can strip away the skin’s protective oils and moisture from the skin. Commercial soap usually often contains sodium lauryl sulphate (SLS), which is a caustic detergent that is usually found in carpet cleaner, car wash. The next time you walk down the soap aisle at the store enjoying the clean scent and colorful packaging…Pay attention and look at the labels. SUMU-SU Soap, however, is handcrafted with 100% natural ingredients and is designed to provide moisturizing properties to the skin. It is combined with nature’s own pure vegetable, distilled rice water, pure essential oils and organic botanicals. It does not contain any sodium lauryl sulfate (SLS), synthetic fragrances, colorants and preservatives.
What is Sodium Lauryl Sulfate (SLS)?

How are your soap made?
Our soap is cold process soap, which require mixing lye and oils together. With the chemical reaction, the soap goes through the saponification process and the curing process, which takes about 4-6 weeks.
What does curing soap mean? Why does that take 4-6 weeks?
Curing the soap means slicing it up, allowing airflow between the bars, letting the water evaporate, which makes the soap gentler. A long cure is necessary to produce the best quality of a bar of soap. Did you know some of the food products require lye? Some of the food products such as olives (make it less bitter), bagels or pretzels require lye (sodium hydroxide) to make the final products. Lye can be dangerous, however, as long as the correct amount is being used and it goes through the chemical reaction, the result is safe.
Is there lye in your soap?
Soap making requires lye in the process. The lye and oils are combined during the saponification once the saponification process is completed. There is no lye in the finished bars of SUMU-SU soap. What is the difference between essential oil and fragrance oil? Essential oils are extracted from plants and fragrance oils, as known as perfume oils, are usually synthetic. Fragrance oils do not possess the natural healing properties of essential oils and can cause skin irritation.
