Science
Mechanism of Action
As an ethoxylated surfactant, Amarantheth-20 reduces interfacial tension between oil and water, facilitating stable liquid crystal emulsion formation. Its amaranth base provides emollients like squalene and tocopherols, replenishing the skin's lipid barrier to reduce TEWL.
