"Sodium" refers to the element sodium. "laureth-" denotes a PEG (polyethylene glycol) ether of lauryl alcohol. The number after "Laureth-" indicates the average number of molecular units -CH2-CH2-O-. Phosphates are salts or esters of phosphoric acid.
Sodium laureth-4 phosphate is a substance which is used in cosmetic preparations where it acts as a surfactant (washing-active substance) and emulsifier (changes the interfacial tension of liquids like water and oil so that they can be mixed together).
