A refreshing fusion of luscious lemon accord and sun kisssed sweet raspberries. Contains: Sodium Bicarbonate, SLSA, Cream of Tartar, Corn starch, Cocoa Butter, Glycerine, Polysorbate 80, fragrance. SLSA is Natural SLS is NOT...I make my bubble bars from sodium lauryl sulfoacetate SLSA (that's what makes the bubbles) It is a NATURAL product made from coconut and palm oils and Decyl Glucoside which is a natural, non-drying surfactant obtained from renewable plant based fatty alcohols glucose and coconut. Glycerin act as natural humectants and Boost bubbles!How to use a Bubble Bar.Break up your bubble bar in single bath portions. Most of my bubble bars are good for 3 to 4 baths depending on the hardness of your water and how many bubbles you want in your tub. Store remaining pieces in a zip-lock to keep away from humidity. Turn on your water and hold the bubble bar under the running water. Hold it until it is completely desolved. For the best results use hot water, agitate the water after your bubble bar is disolved and don't use any bath salts, salt will kill the bubbles. Lay back and enjoy!
