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.

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

Wetting Efficiency

Wetting efficiency on textiles

Wetting efficiency on textiles, Cotton disc method (DIN EN 1772), 1 g/l in D.I. water, 20 °C

The wetting efficiency on textiles is an important criterion for assessing the performance of a surfactant. The wetting times of the alcohol ethoxylates were determined in aqueous solutions on cotton fabrics. The wetting performance, which corresponds to the time taken for a cotton disc to sink in aqueous solution, is a function of the degree of ethoxylation. The shorter the sinking time, the better the wetting efficiency

Wetting efficiency on hard surfaces

The wetting performance on hard surfaces such as metal or plastics can be assessed by contact angle measurements. The contact angle indicates how far a droplet of a surfactant solution spreads on the given surface. The lower the contact angle the better the wetting efficiency on the surface. Hydrophobic surfaces like plastics are usually more difficult to wet with water than hydrophilic surfaces. Ethoxylates based on short chain alcohols show an excellent reduction of the surface angles on hard surfaces compared to pure water.

Foaming Profile

Ethoxylates based on short chain alcohols are moderate to high foaming surfactants. Figure 4 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 behaviour is determined by the SITA foam method (foam generated by a rotating disc).
