- 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.

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

Technical Details & Test Data
- Foaming Profile
Ethoxylates based on short chain alcohols are moderate to high foaming surfactants.shows the foaming profile of MARLIPAL 10, BIODAC x10 and LIALET 111 ethoxylates.
At room temperature the foam level of the ethoxylates increases with increasing degree of ethoxylation. The foaming behavior is determined by the SITA foam method (foam generated by a rotating disk).
