A foaming and cleansing agent. We use primarily decyl polyglucose (which is derived from corn and coconut oils) in combination with other plant-based cleansers. They are very mild and make suds that are rich and creamy. Decyl polyglucose is a fatty polyglycoside prepared by reacting cornstarch glucose with natural fatty alcohol. Sodium Laurel Sulfate or Sodium Laureth Sulfate are the most common surfactants found in personal care. There are many rumors that these ingredients cause cancer. Even though these rumors are unsubstantiated, we don't use them because they are cheap detergents that can be irritating to skin and eyes.

A substance produced in the lungs that reduces surface tension and helps keep the small air sacs open.
The primary ingredient in most cleaners. Surfactants improve the penetrating power of water, create suds, and dissolve grease. The name is a conjunction of the terms surface active ingredient, which describe its function. Most surfactants are skin and eye irritants, and most are quite toxic to aquatic animals, hence the importance of their biodegradability. Surfactants are classified as anionic, nonionic, or cationic on the basis of their electrical charge.*surfactants (uncharacterized): Eye irritant. Used in a wide range of household cleaning products.
