SNO products contain only fruit and vegetable extracts for both our primary actives and surfactants. The predominant active in most of our products is a purified de-oiled citrus. This gives our products the commercial strength and the high dilution rates, thus making them very affordable when Ready to Use. Other ingredients include extracts from coconut, palm, and soybean primarily and other vegetable esters. Because our products are de-oiled they are more versatile to use on mirrors, windows, and other surfaces where streaking is a consideration. All of our products score a Zero on the hazardous listing of the MSDS which you can view http://www.thesnocompany.com/library/ just type in MSDS and a list will be viewable
