Surface Active Property

One of the most characteristic properties of surface active agents is their ability to reduce the surface tension of water. Ethoxylates based on short chain alcohols provide a typical surface tension reduction. Upon addition of ethoxylates, the water surface tension of 72 mN/m can be reduced to values below 30 mN/m

The Critical Micelle Concentration (CMC) is a further characteristic property of a surfactant. The CMC is the concentration at which single surfactant molecules start to build micellar aggregates. CMC values as well as surface tension data at 0.1 g/l resp. 1.0 g/l for the ethoxylates based on short chain alcohols are recorded

Solubility and Gel Formation With Water

Solubility in water

As for all alcohol ethoxylates the solubility of this product group mainly depends on the base alcohol and the length of the water soluble polyethylene glycol ether chain. Accordingly, the solubility increases with the degree of ethoxylation. Ethoxylates based on short chain alcohols with 3 to 5 moles of EO are only sparingly soluble in water whereas higher ethoxylated types are readily soluble in water and show excellent wetting properties.

Gel formation in water

Aqueous solutions of short chain alcohol ethoxylates cover a large range of viscosities from free flowing liquids to solid gels in dependence of the amount of water added. The gel phases typically occur at medium concentrations and can have significant stability even when additional water is added.

Overview of the gel formation of the different alcohol ethoxylates.

Storage and Handling
  • LIALET 111-7 should preferably be stored in stainless steel tanks. It is suggested to keep the product at temperature below 40°C, it is preferable to avoid heating above 60°C and to store under nitrogen in order to minimize yellowish phenomena.
  • LIALET 111-7 is a cloudy liquid at room temperature and it becomes homogeneous and transparent at temperature about 30°C, it becomes a solid wax at t emperature lower than 15°C.
  • Improvement of appearance and handling at low temperature can be achieved by mixing the product with 15 weight% water to obtain a clear liquid up to a temperature about 5 - 10 C°.
  • Shelf-life is 36 months from production date for product in its original and sealed packaging.
