Sodium pareth sulfate, also known as sodium polyoxyethylene alkyl ether sulfate, is a surfactant found in some detergent products such as hand or body washes, but not as commonly as other chemicals such as sodium laureth sulfate (SLES). It is the sodium salt of a sulfated polyethylene glycol ether.
It is produced similarly to SLES starting from fatty alcohols with 10 to 16 carbon atoms.[1]
