C12-13 PARETH-2.

Valuable CAS 66455-14-9 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A nonionic surfactant and emulsifying agent that helps stabilize formulations by reducing surface tension between oil and water phases. With its low HLB value of 6.3, it excels as a co-emulsifier in both oil-in-water and water-in-oil systems.

Summary
