We use only the highest quality solution for our foam. It’s 100% bio-degradable, non-staining, non-toxic, and hypoallergenic! It’s also safe for babies, pets, and the environment including lawns and gardens. Our foam is made up of Sodium Lauryl Sulfate, Glycerol & Water. These are also the main ingredients used in things like hand soap, toothpastes, shampoos, shaving creams, and bubble bath formulations but without the additional chemicals and perfumes. Sodium Lauryl Sulfate (SLS), a cleaning agent and surfactant, is an ingredient in many personal care and cleaning products. SLS is derived from natural sources like coconut and palm kernel oil. Multiple scientific bodies have reviewed SLS as an ingredient in personal care and cleaning products and determined its typical use in these applications to be safe for both consumers and the environment. The U.S. Food and Drug Administration (FDA) includes SLS on its list of multi-purpose additives allowed as a direct food additive. For more information on SLS click here. Glycerol, sometimes referred to as glycerin, is sugar alcohol widely used in a variety of personal care products, including toothpaste, hair conditioner, cosmetics, and moisturizers. The FDA is the primary regulator of over-the-counter products and food packaging materials. FDA has approved glycerol for use as an additive to food packaging materials. Glycerol also has been approved for use in skincare products. FDA has placed glycerol on its Generally Recognized as Safe List. For more information on Glycerol click here.
