Sodium c pareth sulfonates (inci)

"Sodium" refers to the element sodium. "Pareth-" denotes a PEG ether of an alkyl alcohol. The prefixed numbers "C x-y" indicate the length of the alkyl (carbon) chains. The number after "Pareth-" indicates the average number of molecular units -CH2-CH2-O-.

Sodium C pareth sulfonates are substances which act as emulsifiers (surface-active substances which are used as additives in cosmetic products in order to combine two immiscible liquids - e.g. oil and water - into an emulsion) or as surfactants (washing-active substances).

Agents that act as surfactants are

Sodium C12-15 pareth-15 sulfonatesSodium
C12-15 pareth-3 sulfonatesSodium
C12-15 pareth-7 sulfonates.

Agents which act as emulsifiers are

Sodium C12-15 pareth-3 sulphonatesSodium
C12-15 pareth-7 sulphonates.
