Tween™ L-1505

Add to favourites
Tween L-1505 forms part of the Tween L series, evolved from the existing Tween polysorbate product line by including ethylene and propylene oxides to provide differentiated formulation and use benefits. Tween L-1505 has a high HLB (12.7) and low log P (1.92), offering superior spray retention and spreading for contact active ingredients. Tween L-1505 retains core polysorbate safety advantages while offering an effective green chemistry alternative to traditional ethoxylated alcohols, alkoxylated alcohols and NPE’s.
