Gentlex™ 611 L UP is an alkanolamide free, very mild, high pH and thus self-preserving, high active surfactant concentrate. A synergistic combination of high foaming/anionic surfactant, a cocamidopropyl betaine, and lauryl glucoside designed to build maximum viscosity even at low active levels. Gentlex™ 611 L UP can be diluted to yield high foaming, non-alkanolamide containing shampoos, body washes and skin cleansers with excellent viscosity potentiation. It can be used to make mild, high foaming light duty detergents such as hand dishwash detergents.
