Vanconol® LFS-1904 Non-Foaming Surfactant
Abstract
Vanconol® LFS-1904 Non-Foaming Surfactant has a chemical composition of a mixture of acetylenic diol polyether and branched alcohol polyether. This product offers excellent dynamic surface tension performance, low foam, penetration, emulsification, dispersion and detergency properties. It is an excellent emulsifier with strong emulsifying power and non-foaming behavior, is stable in acidic and alkaline solutions, and has strong formulation versatility, allowing use together with other nonionic and anionic surfactants in cleaning and dyeing formulations that require low foam.
