STEPANOL® WA-100

1 of 52 products in this brand
STEPANOL® WA-100, derived through Stepan's advanced sulfation process of fatty alcohol with SO3, is a high-quality, spray-dried sodium lauryl sulfate powder with remarkable purity. Its versatility shines through, as it serves as an excellent foaming agent and mouth dispersant in dentifrices. Notably, its low levels of unsulfated material eliminate the bitter taste often associated with other sodium lauryl sulfates, enhancing the overall sensory experience in toothpaste formulations.

Product Applications

STEPANOL WA-100 can be used as a foaming agent and mouth dispersant in dentifrices. Because of its low levels of unsulfated material, STEPANOL WA-100 will not cause toothpaste formulations to have the bitter taste associated with other sodium lauryl sulfates. STEPANOL WA-100 can also be used in powdered formulations such as hand cleaners and powdered baths and can be used in liquid hand soaps and shampoos.
