Vanconol® LFS-1905 Non-Foaming Surfactant

Vanconol® LFS-1905 Non-Foaming Surfactant

Abstract

Vanconol® LFS-1905 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, non-foaming behavior, penetration, emulsification, dispersion and detergency properties. It has strong emulsifying power, is stable to 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.

Main Features and Advantages

  • Non-foaming characteristics: With a foam volume of only 40 ml, extremely low foam, suitable for formulations that are highly foam-sensitive.
  • Ultra-low dynamic surface tension: Dynamic surface tension as low as 29.6 mN/m, providing excellent wetting.
  • Excellent acid and alkali performance: Exhibits even lower dynamic surface tension under acidic and alkaline conditions.
  • Strong formulation versatility: Can be used together with other nonionic and anionic surfactants.

Recommended Application Fields

  • Low-foam cleaning: Industrial cleaning formulations requiring low foam.
  • Dyeing and printing: Textile dyeing and printing pretreatment and scouring.
  • Acidic and alkaline environments: Wetting, penetration and detergency under acidic and alkaline conditions.
