It's hard to find an example of these surfactants at our suppliers' stores, but I did find Silaphos MDE 124, INCI laureth-4-phosphate (the alkyl ether type of phosphate, sometimes found as sodium laureth-4-phosphate).

Surfactants: Phosphate esters (category)
Phosphate esters are a category of anionic surfactants that include alkyl phosphates and alkyl ether phosphates. We don't use phosphate esters in our bath & body products much as they are generally used in household cleaning products due to their low pH. They are very mild to the skin and might show up in facial or body cleansing products.
